The deleterious effects of screen time on young children include focus issues and emotional dysregulation. As used in the sentence above deleterious means:
Rationale:
Deleterious means harmful. The context highlights negative consequences of screen time on young children, specifically mentioning focus issues and emotional dysregulation, indicating that screen time adversely affects their well-being and development.
A: fateful. This option suggests an inevitable or disastrous outcome, which does not align with the context of describing negative effects on children's health and behavior.
B: prodigious. This term implies something remarkably great in extent or size, which contradicts the context that emphasizes adverse effects rather than significant or impressive attributes related to screen time.
D: minimizing. This word refers to reducing or lessening something, which does not relate to the negative impacts outlined in the context regarding the harmful consequences of screen time on children.
Ever since the president, vice-president, secretary, and treasurer resigned, the general has been the virtual ruler of the country. Virtual means
Rationale:
Virtual means informal, indicating that the general holds power in a manner that is not officially recognized or sanctioned but still exerts significant influence over the country's governance. This aligns with the context of the general's role following the resignations of key officials.
B: surreptitious suggests secretive actions, which does not accurately describe the general's influence as it is openly acknowledged despite lacking formal authority.
C: indiscrete implies a lack of discretion, which does not relate to the nature of the general's authority, focusing instead on behavior rather than power dynamics.
D: incomparable suggests uniqueness or a lack of equivalent, which does not pertain to the essence of informal authority that the term "virtual" conveys in this context.
1. In October 2018, James P. Allison and Tasuku Honjo were awarded the Nobel Prize in Physiology of Medicine for their groundbreaking efforts in inhibiting the impact of cancer in patients through immunotherapy. James P. Allison, 70-year-old immunologist and native Texan, works at the prestigious Anderson Cancer Center in Houston. Tasuku Honjo is a 76-year-old immunologist and native of Kyoto, Japan who currently leads a variety of important medical research efforts at Kyoto University. Their research efforts span several decades, in two extremely different national contexts, but their recent international collaborations have reignited the profession over the last ten years.
2. Together, their cutting-edge research has helped make cancer immunology one of the most innovative branches in the field of medicine. Their current project, which focuses on mitigating negative immune regulation, has helped uncover new strategies for “inhibiting the brakes of our immune systems” through T-cell immunotherapy. Though cancer rates continue to decline throughout developed countries, it still remains the second leading cause of global mortality rates, contributing to millions of deaths each year. Thanks to their findings, many research initiatives, which had previously given up on the prospects of immunotherapy practices, are reinvesting hundreds of millions of dollars into an entirely new class of drugs that might help
According to the article, which statement is true?
Rationale:
James P. Allison and Tasuku Honjo have discovered new relationships between certain proteins and cancer. Their research, particularly focusing on T-cell immunotherapy, reveals how immune regulation can be manipulated to combat cancer effectively. This innovative approach has significantly advanced cancer immunology, showcasing their contributions to understanding and treating cancer through immunotherapy strategies.
A: CTLA-4 and PD-1 are two types of cancer that have been cured by CTLA-4 and PD-1. This statement misrepresents the terms; CTLA-4 and PD-1 are immune checkpoint proteins, not types of cancer.
B: All cancers have been cured by James P. Allison and Tasuku Honjo's therapeutic practices. Claiming all cancers are cured is exaggerated; their work has advanced immunotherapy, but not all cancer types are resolved.
D: James P. Allison and Tasuku Honjo just recently started studying cancer. Their extensive research spans several decades, indicating long-term commitment to cancer study, contradicting the assertion of a recent commencement.
The teenagers' guilty…………. caused them to confess to the vandalism of the school locker room.
Rationale:
The teenagers' guilty conscience caused them to confess to the vandalism of the school locker room. A conscience refers to an inner sense of right and wrong, prompting feelings of guilt that can lead to confession. In this context, the teenagers’ moral awareness compelled them to admit their wrongdoing regarding the vandalism incident.
A: consensus A consensus involves a general agreement among a group, which does not apply to the teenagers' individual feelings of guilt and moral responsibility in this situation.
B: conscious A conscious state refers to being aware or alert, lacking the emotional depth associated with feelings of guilt that would drive a confession.
C: conscientious Conscientious relates to being diligent and responsible, but it does not capture the emotional aspect of guilt that leads to the teenagers’ confession.
1. Forty years ago, a person diagnosed with type 1 diabetes (T1D) would have found their life altered considerably. T1D frequently begins to manifest in childhood but can be diagnosed at any age. However, thanks to recent advances, managing this chronic condition now comes with conveniences that allow for less worry and fewer challenges for people who live with T1D.
2. People with T1D must be attentive to their food intake, carefully monitor their blood glucose levels, and take regular doses of insulin tasks that often make people feel alienated from their friends who are able to eat what they want without worry. If someone with T1D takes too much insulin for their food, they can experience hypoglycemia, a sudden drop in blood sugar, leading to debilitating symptoms such as headache, sweating, shakiness, and even fainting. But if they don't take enough insulin, they will experience hyperglycemia which causes symptoms such as excessive thirst, frequent urination, lethargy, headaches, and blurred vision.
3. Recently, however, advances in blood glucose monitoring and insulin delivery have simplified disease management for many people with diabetes. Roughly 64% of current patients with T1D in the U.S. use an insulin pump for consistent, accurate delivery of insulin rather than relying on daily insulin injections (Smith & Harris, 2018). Insulin pumps generally contain an insulin reservoir and a computer chip that monitor insulin delivery through a cannula inserted under the patient's skin, usually on the lower part of the stomach. While the cannula site must be changed every few days, the pump frees the individual from needing frequent injections and delivers insulin more consistently than Injections.
4. Additionally, patients can now also use a continuous glucose monitor (CGM) to promote better regulation of blood sugar. CGMs use a sensor inserted under the skin to transmit blood glucose information to a smartphone app or even directly to an insulin pump. Patients can then use an app to monitor their insulin intake and blood sugar at any given time, Furthermore, the app can alert the patient to changes in blood sugar that could lead to dangerous reactions. Patients and their caregivers can use the information stored on the app to adjust diet and Insulin delivery to promote better overall health (Wong, 2023).
5. Perhaps the most exciting recent development in diabetes management is that of the hybrid, closed-loop system, or artificial pancreas. In 2016, the FDA approved the first of these devices, which combine glucose monitoring and insulin delivery in one automated system (Smith & Harris, 2018). These systems, now commercially available, allow patients with T1D a level of ease of management that enables them to go about daily tasks without the need to carry kits containing syringes, vials, finger prick devices, and test strips.
6. While a cure for T1D remains a goal of researchers, consistent improvements in patient care and management have vastly improved life for many patients living with T1D. While patients wait for a cure, modern medical technology now offers them a vastly improved quality of life
A major advantage of the hybrid closed-loop system is that it
Rationale:
Provides automated monitoring and insulin dosing with minimal input from the patient. This innovation significantly reduces the burden of diabetes management, allowing individuals with T1D to focus on daily activities without constant intervention in their treatment.
A: keeps the patient disciplined about diet and treatment. While discipline is important, the hybrid closed-loop system primarily automates monitoring and dosing, reducing the need for constant manual management.
C: eliminates the need for consistent treatment. The system does not eliminate treatment; rather, it simplifies and automates insulin delivery, ensuring ongoing management is still necessary for health.
D: results in fewer hospitalizations related to management of T1D. Although the system may improve management and reduce complications, it does not guarantee fewer hospitalizations, as other factors influence patient health.
To unify the group, the president suggested a slogan contest to foster
Rationale:
To unify the group, the president suggested a slogan contest to foster connectedness. This approach encourages collaboration and shared identity among members, making it easier for individuals to bond over a common goal and feel a stronger sense of belonging within the group.
A: invigoration. While invigoration implies energizing the group, it does not specifically address the relational aspect that a slogan contest aims to enhance.
B: enlightenment. Enlightenment focuses on gaining knowledge or insight, which does not capture the essence of creating unity and relationships among the group members through a shared slogan.
D: stimulation. Stimulation suggests excitement or activity; however, it overlooks the essential element of building meaningful connections, which is the primary goal of the slogan contest.
1. When e-cigarettes, more commonly known as vapes," first came on the market, they were touted by their makers as a far safer way to enjoy the pleasures of smoking. However, while it is true that vaping is less dangerous than cigarette smoking recent research has revealed that the use of e-cigarettes, especially among young people, poses serious health risks.
2. Being "less dangerous" than cigarettes is hardly a stamp of approval for vapes. After all, according to the Centers for Disease Control and Prevention (CDC), long-term cigarette smoking kills half of all users. While e-cigarettes may not be quite this deadly, it is clear that addiction to nicotine -which, the CDC notes, is present in 99% of all vape products (2022a) - is unhealthy, furthermore, scientists have yet to fully learn or understand the long-term health effects of vaping.
3. Of particular interest to health officials is the fact that vape use has reached troublesome proportions among young people, and there are specific health concerns for these younger users. According to the CDC, in 2022, 1 in 7 high school students and 1 in 30 middle school students reported that they had usedavape product in the last 30 days (2022b). These numbers are deeply troubling given the unique health consequences vape products can have on young people.
4. Our brains don't finish developing until about the age of 25. According to the CDC (2022a), "Each time a new memory is created or a new skill is learned, stronger connections - or synapses -are built between brain cells. Young people's brains build synapses faster than adult brains. Nicotine changes the way these synapses are formed." These changes can affect processes like attention, learning, and impulse control. Furthermore, addiction to nicotine can lead to mood disorders, and nicotine can serve as a gateway drug to substances such as marijuana (which can also be delivered by vape), heroin, and cocaine. The CDC also reports that many young people are using nicotine to self-medicate, an unhealthy and ultimately ineffective way to deal with stress, anxiety, and depression. 5. Beyond these risks, scientists are still learning the other possible harmful effects of e-cigarettes. The CDC notes that some ingredients in the aerosol produced by vapes may be harmful to lungs, and we may see more of this damage as use becomes long-term. Some vapes have been known to explode or catch fire, gravely injuring their users.
Which question is left unanswered by the article?
Rationale:
Vaping's impact on long-term health remains unanswered. While the article discusses the immediate risks and addiction associated with vaping, it emphasizes that scientists have yet to fully understand the long-term health effects, leaving this question open.
A: Why were e-cigarettes developed? The article does not address the motivations or historical context behind the development of e-cigarettes, focusing instead on their current health implications.
C: How does nicotine affect young brains? Although the article mentions nicotine's effects on synapse formation in young brains, it does not delve into the specifics of those effects, leaving the question partly unanswered.
D: How common is e-cigarette use among teens? The article provides statistics on teen vaping prevalence, clearly answering this question with specific figures from the CDC regarding usage among high school and middle school students.
1. In 2010, author Rebecca Skloot published The Immortal Life of Henrietta Lacks, the story of a Black woman who died of cervical cancer in 1951. The book, an immediate bestseller, examines the roles of race, class, gender, and ethics in medical research and considers the implications, both positive and negative, of Henrietta Lacks's remarkable but inadvertent role in some of the most significant medical advances of the twentieth century.
2. In 1951, Lacks, a 30-year-old wife and mother of five, went to Johns Hopkins Hospital in Baltimore for treatment of cervical cancer. She was unable to pay for treatment and stayed in a segregated ward. During a procedure to place radium on her tumor, Lacks's doctor cut a sliver from the tumor, placed it in a petri dish, and handed it off to the lab assistant of George Gey, a Johns Hopkins cancer researcher. Sadly, cervical cancer is a particularly pernicious disease, and Henrietta succumbed in October 1951 after a brief but terribly painful struggle, leaving behind her young children.
3. George Gey had been trying unsuccessfully to grow human cells in culture - until Henrietta's cells arrived. Labeled HeLa, Henrietta's cancer cells doubled in culture within 24 hours - and they never stopped. HeLa cells multiplied so rapidly and persistently, Gey eventually began giving them away to other researchers. According to Skloot, Hela became the "workhorse" of research labs everywhere. They were used to test the polio vaccine and in the development of HIV medications and cancer treatments. HeLa cells were central to the development of the HPV vaccine and were some of the first human cells sent into space to determine how zero gravity affected human cellular activity.
4.While Gey never profited from Hela cells, eventually others did. HeLa "factories" soon sprang up, and researchers and labs could order vials of HeLa cells through catalogues. The production and sale of HeLa cells became a multi-million-dollar industry. Lacks's surviving children, however, continued to live in poverty in Baltimore, unaware of their mother's contributions to science
5. Media coverage and scientific interest eventually made its way to the Lacks family. Scientists sought the children's DNA to better map Henrietta's genome, and the media sought to learn more about the woman behind the cells. One journalist easily obtained Henrietta's medical records and published large portions of them without the family's knowledge or consent. Thousands profited from HeLa cells and their story, but the Lacks family never saw a penny.
6. Today, laws protect patients' privacy and require consent for all invasive medical procedures. However, the debate about who owns human tissue once it has left its owner's body is still unsettled. The legal and scientific communities must balance the rights of human subjects with the benefits to science that human cells can provide. the rare occasions when human cells provide the kind of scientific - and economic value that HeLa did, who should benefit? While there is no doubt that the Lacks family was first dismissed and later exploited, this bioethical debate is far from settled.
HeLa cells are considered immortal because
Rationale:
HeLa cells multiplied every 24 hours in culture and never stopped. This unique characteristic of continuous division is what defines them as "immortal," allowing significant contributions to medical research and treatments.
A: they didn't die even when exposed to toxins. The notion of cells not dying from toxins does not capture the essence of HeLa's immortality, which is based on their relentless replication.
C: they can cure diseases when injected into patients. While HeLa cells are pivotal in research, they do not directly cure diseases upon injection; their significance lies in their use for testing and studies.
D: they led to a cure for HIV and cancer. HeLa cells facilitated research advancements but did not directly lead to cures; they are instrumental in understanding diseases rather than being standalone solutions.

It can be inferred that Rebecca Skloot
Rationale:
Rebecca Skloot disapproves of the way the science community treated Lacks and her family. The narrative emphasizes the ethical implications surrounding Henrietta's story, highlighting the exploitation and lack of consent her family experienced, which Skloot critiques throughout her book, advocating for recognition of Henrietta's contributions and the importance of respecting individual rights in medical research.
B: thinks that people should profit when their tissue donations prove to be useful. The text does not suggest that Skloot advocates for profit from tissue donations; rather, it critiques the lack of consent and compensation for Lacks's family.
C: approves of George Gey's decisions but not of other researchers' decisions. Skloot's work does not indicate approval of Gey’s actions; instead, it highlights ethical concerns regarding exploitation and the broader issues within medical research practices.
D: believes HeLa's value to science outweighs Henrietta's individual rights. Skloot’s narrative focuses on the ethical dilemmas and personal rights, indicating a belief that individual rights should not be overshadowed by scientific advancement.
A student dilutes a solution with water, this causes the concentration to
Rationale:
Diluting a solution with water causes the concentration to diminish. This occurs because adding water increases the volume of the solution while the amount of solute remains constant, resulting in a lower concentration of solute per unit volume.
A: strengthen. Adding water cannot enhance the concentration; instead, it spreads the solute over a larger volume, leading to a reduction in concentration.
B: propel. This term implies movement or force, which is irrelevant in the context of concentration changes resulting from dilution with water.
C: waver. Wavering suggests fluctuation or instability, which does not accurately describe the consistent decrease in concentration that occurs when a solution is diluted.
1. "They won't starve; if they're hungry enough, they'll eat." Parents of "picky" eaters hear this statement from well-meaning friends and fellow parents all the time. However, for parents of children with Avoidant Restrictive Food Intake Disorder or ARFID, the statement is untrue.
2. According to the National Eating Disorders Association (NEDA), between 0.5% and 5% of the general population may have ARFD. The disorder often affects young children and can be distinguished from simple pickiness; individuals with ARFD restrict their diet so severely, they suffer poor health as a result. In very severe cases, malnutrition and failure to thrive can occur.
3. ARFID is considered an eating disorder and a psychological condition; however, unlike other eating disorders such as anorexia and bulimia, people with ARFID do not restrict their food intake out of concern for their appearance or weight. Sufferers of ARFID limit their diet due to a lack of interest in food or out of a sense of extreme anxiety or fear around food and the process of eating (Eddy, n.d.).
4. While the causes of ARFID aren't yet well understood, traumatic events involving eating, such as a choking incident, a severe allergic reaction, or painful responses to food (cramping, diarrhea, or vomiting), can lead to worsening restrictive behavior. However, not all cases can be traced to such an incident. Children with ARFID may also suffer from sensory challenges that cause them to avoid certain food textures and flavors. Common comorbidities include ADHD, autism spectrum disorder, depression, and anxiety (Eddy, n.d.).
5. Attempting to pressure a child with ARFID to eat something they are uncomfortable with can heighten their anxiety around food and mealtimes. Instead, families of children with ARFID should seek treatment. Cognitive behavior therapy is the recommended treatment, though some patients may also need medication for anxiety or underlying physiological feeding issues. NEDA also notes that family-based therapy may be helpful for children with ARFID. Left untreated, ARFID can lead to serious physical health conditions in patients.
6. Multiple resources designed to help parents with children diagnosed with ARFID are available. NEDA lists a number of resources on its website, Additionally, numerous social media support groups have formed. One of the most notable resources is the Instagram feed of 8-year-old Hannah. Recently featured on ABC News, Hannah's Instagram, titled "My ARFD Life," shares videos of her experiences with foods. In a technique known as exposure therapy, Hannah is gradually introduced to new foods, exploring their texture. smell, and other features before eventually tasting them and sharing her reaction with her followers.
7. Like other mental health conditions, ARFID poses immense challenges to those who suffer from the disorder and to their families. The risks to physical and overall mental health can be scary, as well. Fortunately, as new information comes to light regarding this recently identified disorder, resources and professional knowledge have begun to increase. With proper care and support, patients with ARFID can drastically improve their quality of life.
ARFID is similar to other eating disorders in that it:
Rationale:
ARFID can lead to serious medical complications in patients. This disorder is characterized by extreme dietary restrictions, resulting in malnutrition and, in severe cases, failure to thrive, highlighting the significant health risks involved.
A: is caused by an individual's view of their appearance. ARFID does not stem from concerns about appearance; it arises from anxiety and lack of interest in food, distinguishing it from other eating disorders.
B: occurs mainly in adolescents and young adults. While ARFID can affect any age group, it primarily impacts young children, contrasting with other eating disorders that often manifest in older adolescents and adults.
D: can be made worse by media messages around ideal body types. Unlike disorders driven by appearance concerns, ARFID's causes are largely rooted in anxiety and sensory challenges, making media messages less relevant.
Given the words vitamin, revitalize, and vital, what does the root vit mean?
Rationale:
Life. The root "vit" originates from the Latin word "vita," meaning life. This root underscores the importance of vitality and the essential nature of life itself, connecting to terms like vitamin and revitalize, which emphasize nourishment and rejuvenation.
B: essential. While "vit" suggests importance, it specifically denotes life rather than merely essentiality, which does not encompass the full depth of the root's meaning.
C: healthy. The term healthy pertains to well-being, but it does not capture the fundamental essence of life inherent in the root "vit."
D: birth. Birth refers to the beginning of life, yet "vit" is rooted in the ongoing concept of life, not solely its inception or origin.
The highly vaunted team was preparing for the playoffs. Vaunted means
Rationale:
Vaunted means boasted about. In the context of the highly regarded team preparing for the playoffs, it indicates that their achievements and skills have been widely praised and celebrated, highlighting their reputation in the competitive arena.
B: worked over This suggests a sense of being manipulated or overworked, which does not convey the sense of admiration associated with vaunted.
C: absolutely servile This implies a submissive or subservient attitude, contrasting sharply with the positive connotation of vaunted, which denotes respect and acclaim.
D: most captious This refers to being overly critical or nitpicking, which does not align with the celebratory and esteemed nature of the term vaunted.

The author of the passage probably included Henrietta's age and mentioned her young children in order to
Rationale:
Henrietta's age and her young children evoke empathy and highlight the tragedy of her untimely death, emphasizing the human cost behind her medical legacy and the ethical considerations it raises.
A: point out how dangerous cancer is. While the passage discusses cancer's severity, the mention of Henrietta's family specifically aims to elicit emotional resonance rather than simply illustrate cancer's dangers.
C: suggest that Henrietta's age led to the immortality of her cells. The text does not imply any connection between her age and the unique characteristics of her cells; they are instead attributed to their biological properties.
D: suggest that Henrietta's children might also have immortal cells. The extract focuses on Henrietta's contributions and does not indicate any potential for her children to possess similar immortal cells, making this option unrelated.
The athlete's performance required the application of his practical experiences. Application means
Rationale:
Application means putting into action. This aligns with the context, as the athlete's practical experiences must be actively utilized to enhance performance, demonstrating the necessity of translating knowledge into tangible efforts.
A: making an attempt. This implies a trial without the connotation of using prior experiences effectively, which is essential for optimal performance in athletics.
C: taking a risk. This suggests uncertainty or danger, which does not capture the essence of utilizing experiences in a structured, purposeful manner during performance.
D: putting to use. While similar, this phrase lacks the immediacy and active engagement implied by "putting into action," which emphasizes the dynamic nature of applying experiences.
My new rain boots are supposed to be to water. Which word should go in the blank?
Rationale:
My new rain boots are supposed to be impervious to water. This answer is appropriate as "impervious" means not allowing fluid to pass through, which is essential for effective rain boots designed to keep feet dry.
B: Precipitate refers to a process of causing something to happen suddenly, unrelated to waterproof characteristics. It does not convey any resistance to water.
C: Susceptible denotes vulnerability or likelihood of harm, which contradicts the purpose of rain boots that should protect against water exposure.
D: Immune suggests a resistance to something, typically in a biological context. It does not accurately describe the waterproof nature of rain boots.

6. While scientists are still learning about its effects, it is already clear that vaping is a dangerous habit, especially for young people. The Federal government, schools, parents, and the healthcare industry are grappling with ways to effectively educate young people on this dangerous habit.
Based on the passage, one could infer that
Rationale:
Vaping is more harmful to young people than to adults. This inference is supported by the passage, which highlights the unique health risks vaping poses to young users, particularly concerning brain development and addiction to nicotine, which can lead to mood disorders and unhealthy coping mechanisms.
B: vaping is not a problem for young people in middle school. The extract reports that 1 in 30 middle school students used a vape product, indicating it is indeed a significant concern.
C: vaping may be more dangerous than cigarette smoking. While vaping has serious health risks, the passage emphasizes that it is less deadly than traditional cigarettes, not more dangerous.
D: vaping causes mental health illnesses. The passage notes that nicotine addiction can lead to mood disorders, but it does not explicitly state that vaping directly causes mental health illnesses.
Which pair of words below represents antonyms?
Rationale:
Intermittent - constant represents antonyms. Intermittent refers to something occurring at irregular intervals, while constant denotes something that is unchanging and continuous, highlighting their opposing nature in frequency and duration.
A: malicious - pernicious both involve harmful intent, lacking a contrasting relationship as both suggest negative effects rather than opposing meanings.
C: interminable - infinite both imply endlessness, failing to showcase contrasting ideas since they both describe something that has no limits.
D: egregious - extreme both suggest a high degree of severity or intensity, thus lacking opposition and representing similar magnitudes rather than contrasting concepts.
The company interviewed twelve…………... candidates for the new management position.
Rationale:
Twelve prospective candidates were interviewed for the new management position. This choice is fitting as "prospective" refers to individuals who are likely to be selected for a future role, aligning perfectly with the recruitment context.
B: perceptive Candidates possessing strong observational skills do not align with the recruitment context. The focus here is on potential hires rather than their ability to understand or interpret situations.
C: perspective This term refers to a viewpoint or angle of consideration, which does not relate to the selection process for individuals. It fails to address the nature of the candidates being interviewed.
D: accepted The term suggests individuals who have already been approved or confirmed, which contradicts the scenario of interviewing potential hires for a management position yet to be filled.
1. The 1960s and 1970s are often distinguished as hallmark decades for free speech and free expression in American history- the civil rights movement, feminist movement, and free speech movement all have their roots in the tumultuous Sixties and Seventies. As stated in Welner, Kim, and Biegel (2017), "In the 1960s and 1970s, free speech issues were at the forefront of education-related debates, with students asserting themselves in ways they never had before" (p. 33). The late 1960s and early 1970s were ripe with protest, specifically in response to the violent atrocities associated with the Vietnam War. Inevitably, this democratic fervor seeped into the systems and structures of K-12 public schooling. Thus, it is not surprising that this era gave birth to many of the modern constitutional debates regarding students and their First Amendment rights in public schools. In particular, this era gave birth to the landmark Supreme Court case known as Tinker v. Des Moines (1969).
2. Tinker v. Des Moines emerged from the countercultural milieu of the late Sixties: "In December 1965, a group of adults and students in Des Moines, lowa held a meeting. The group determined to publicize their objections to the hostilities in Vietnam and their support for a truce by wearing black armbands during the holiday season and by fasting on December 16 and New Year's Eve" (p. 43). Three students attending that meeting were John Tinker, 15 years old, Mary Beth Tinker, 13 years old, and Christopher Eckhardt, 16 years old. Fueled by the images they witnessed on television broadcasts, Tinker and her classmates decided to wear black armbands as a symbol of youthful resistance and patriotism. The administrators of the Des Moines Independent Community School District caught word of the upcoming protest and hastily adopted a school policy that promised to suspend any students who wore black armbands in protest of the Vietnam War. On December 16 and 17, the administration attempted to squash the public display of solidarity, all three students were suspended from school indefinitely "until they would come back without their armbands" (p. 43).
3. The students' parents fought back, suing the school for violating the children's right to free speech. After a U.S. district court - and later a U.S. court of appeals - ruled against the children and their families, citing that their protest was a disruption and breeched local school standards, the case made its way all the way to the U.S. Supreme Court. The resulting decision of Tinker v. Des Moines set in motion a historical tidal wave of praise and criticism. Promising that students do not "shed their constitutional rights to freedom of speech or expression at the schoolhouse gate," the Supreme Court justices decreed a 7-2 ruling in favor of the protestors. They claimed that the students' silent and symbolic expression was protected under the U.S. Constitution, citing that all political speech in public schools remains guarded by the First Amendment so long as it does not "substantially disrupt the learning environment." In a bold move for the times, the decision claimed that "In order for [a school] to justify prohibition of a particular expression of opinion, it must be able to show that its action was caused by something more than a mere desire to avoid the discomfort and unpleasantness that always accompany an unpopular viewpoint."
4. Tinker V. Des Moines became one of the key democratic victories of the mid-late twentieth century. The decades that followed, however, created clashing currents of belief that were captured by some of the major court cases that reinterpreted the Tinker decision. For the most part, these court cases not only stood as lasting symbols of the political beliefs of the judicial majorities involved, but also as emblems of the socio-historical climate from which they resonated. Less than 20 years after Tinker V. Des Moines, the constitutional precedents made by the landmark decision quickly dissipated, receding into a new sea of social censorship for students. Constitutional reinterpretations of Tinker in the
In what scenario would the Tinker court case most likely be referenced?
Rationale:
A: A case where a student is expelled for speaking out against the school's administration. Tinker v. Des Moines directly addresses students' rights to free speech within schools, particularly regarding expressive actions that do not disrupt the educational environment. This case reinforces the principle that students retain constitutional rights while attending school, making it a relevant reference in such scenarios.
B: A case where a student is suing the school district for a sports injury. Tinker focuses on free speech rights, not on physical harm or injury claims, which fall under different legal considerations.
C: A case where a student is claiming the school was being discriminatory. Tinker emphasizes free expression rather than discrimination issues, which require a separate legal framework to address civil rights violations specifically.
D: A case where a student is arrested for bringing illegal paraphernalia on campus. Tinker pertains to expressive conduct rather than criminal actions, hence it does not apply to cases involving illegal items.
1. Forty years ago, a person diagnosed with type 1 diabetes (T1D) would have found their life altered considerably. T1D frequently begins to manifest in childhood but can be diagnosed at any age. However, thanks to recent advances, managing this chronic condition now comes with conveniences that allow for less worry and fewer challenges for people who live with T1D.
2. People with T1D must be attentive to their food intake, carefully monitor their blood glucose levels, and take regular doses of insulin tasks that often make people feel alienated from their friends who are able to eat what they want without worry. If someone with T1D takes too much insulin for their food, they can experience hypoglycemia, a sudden drop in blood sugar, leading to debilitating symptoms such as headache, sweating, shakiness, and even fainting. But if they don't take enough insulin, they will experience hyperglycemia which causes symptoms such as excessive thirst, frequent urination, lethargy, headaches, and blurred vision.
3. Recently, however, advances in blood glucose monitoring and insulin delivery have simplified disease management for many people with diabetes. Roughly 64% of current patients with T1D in the U.S. use an insulin pump for consistent, accurate delivery of insulin rather than relying on daily insulin injections (Smith & Harris, 2018). Insulin pumps generally contain an insulin reservoir and a computer chip that monitor insulin delivery through a cannula inserted under the patient's skin, usually on the lower part of the stomach. While the cannula site must be changed every few days, the pump frees the individual from needing frequent injections and delivers insulin more consistently than Injections.
4. Additionally, patients can now also use a continuous glucose monitor (CGM) to promote better regulation of blood sugar. CGMs use a sensor inserted under the skin to transmit blood glucose information to a smartphone app or even directly to an insulin pump. Patients can then use an app to monitor their insulin intake and blood sugar at any given time, Furthermore, the app can alert the patient to changes in blood sugar that could lead to dangerous reactions. Patients and their caregivers can use the information stored on the app to adjust diet and Insulin delivery to promote better overall health (Wong, 2023).
5. Perhaps the most exciting recent development in diabetes management is that of the hybrid, closed-loop system, or artificial pancreas. In 2016, the FDA approved the first of these devices, which combine glucose monitoring and insulin delivery in one automated system (Smith & Harris, 2018). These systems, now commercially available, allow patients with T1D a level of ease of management that enables them to go about daily tasks without the need to carry kits containing syringes, vials, finger prick devices, and test strips.
6. While a cure for T1D remains a goal of researchers, consistent improvements in patient care and management have vastly improved life for many patients living with T1D. While patients wait for a cure, modern medical technology now offers them a vastly improved quality of life
As it is used in paragraph 3, the definition of cannula is a
Rationale:
A: syringe used to give an injection. A cannula does not function as a syringe; instead, it is a tube specifically designed to deliver medication continuously, unlike a syringe which administers a single dose.
B: vial containing medication. A vial serves as a container for storing medication, whereas a cannula is a tube that facilitates the delivery of that medication into the body.
C: machine that measures insulin. A cannula is not a measuring device; it is a physical tube that transports insulin from an insulin pump directly into the patient's body.
Choose the pair of words that represent antonyms.
Rationale:
Pacify-provoke represent antonyms. To pacify means to calm or soothe, while to provoke means to incite or stir up emotions. These definitions illustrate a clear opposition in meaning, making them antonyms.
B: punitive-incentive. Punitive refers to punishment, while incentive denotes motivation or encouragement. These terms relate to different aspects of behavior but do not represent opposing concepts.
C: retaliate-sabotage. Retaliate means to respond to an attack, whereas sabotage involves deliberately undermining or obstructing. Both terms imply aggressive actions but do not signify opposite ideas.
D: squander-dissipate. Squander refers to wasting resources recklessly, while dissipate means to disperse or scatter. Although they both involve loss, they do not convey contrasting meanings.
1. When e-cigarettes, more commonly known as vapes," first came on the market, they were touted by their makers as a far safer way to enjoy the pleasures of smoking. However, while it is true that vaping is less dangerous than cigarette smoking recent research has revealed that the use of e-cigarettes, especially among young people, poses serious health risks.
2. Being "less dangerous" than cigarettes is hardly a stamp of approval for vapes. After all, according to the Centers for Disease Control and Prevention (CDC), long-term cigarette smoking kills half of all users. While e-cigarettes may not be quite this deadly, it is clear that addiction to nicotine -which, the CDC notes, is present in 99% of all vape products (2022a) - is unhealthy, furthermore, scientists have yet to fully learn or understand the long-term health effects of vaping.
3. Of particular interest to health officials is the fact that vape use has reached troublesome proportions among young people, and there are specific health concerns for these younger users. According to the CDC, in 2022, 1 in 7 high school students and 1 in 30 middle school students reported that they had usedavape product in the last 30 days (2022b). These numbers are deeply troubling given the unique health consequences vape products can have on young people.
4. Our brains don't finish developing until about the age of 25. According to the CDC (2022a), "Each time a new memory is created or a new skill is learned, stronger connections - or synapses -are built between brain cells. Young people's brains build synapses faster than adult brains. Nicotine changes the way these synapses are formed." These changes can affect processes like attention, learning, and impulse control. Furthermore, addiction to nicotine can lead to mood disorders, and nicotine can serve as a gateway drug to substances such as marijuana (which can also be delivered by vape), heroin, and cocaine. The CDC also reports that many young people are using nicotine to self-medicate, an unhealthy and ultimately ineffective way to deal with stress, anxiety, and depression. 5. Beyond these risks, scientists are still learning the other possible harmful effects of e-cigarettes. The CDC notes that some ingredients in the aerosol produced by vapes may be harmful to lungs, and we may see more of this damage as use becomes long-term. Some vapes have been known to explode or catch fire, gravely injuring their users.
Which title best reflects the content of the passage?
Rationale:
D: Teens and the Dangers of Vaping. This title effectively captures the primary focus of the passage, which discusses the specific health risks vaping poses to young people, emphasizing their vulnerability and the alarming prevalence of vape use among adolescents.
A: Vaping vs. Cigarettes: A Healthy Alternative? This title misrepresents the passage's emphasis on vaping's dangers rather than promoting it as a healthier choice, which is not the central theme discussed.
B: Vaping: A Gateway Drug. While the passage mentions nicotine as a potential gateway to other substances, it primarily highlights the broader health risks facing young users, making this title too narrow.
C: Teaching Teens Not to Vape. This title suggests an educational approach that is not explicitly addressed in the passage. The content focuses more on the dangers rather than on teaching strategies.
The piano tuner tightened the string on the piano, thus increasing the string's
Rationale:
Tension. Tightening the string on the piano elevates its tension, which is crucial for producing higher pitches. The adjustment directly influences the string's physical properties, ensuring accurate tuning and sound quality.
B: length. Tightening a piano string does not alter its length; rather, it adjusts the tension, which affects pitch. Length remains constant when tuning through tightening methods.
C: volume. While increased tension can influence volume, the primary effect of tightening a string is pitch adjustment, not directly enhancing loudness or overall sound output.
D: strength. Strength pertains to the material's ability to resist breaking, not the tension applied during tuning. Tightening the string does not inherently improve its material strength or durability.
1. In October 2018, James P. Allison and Tasuku Honjo were awarded the Nobel Prize in Physiology of Medicine for their groundbreaking efforts in inhibitingthe impact of cancer in patients through immunotherapy. James P. Allison, 70-year-old immunologist and native Texan, works at the prestigious Anderson Cancer Center in Houston. Tasuku Honjo is a 76-year-old immunologist and native of Kyoto, Japan who currently leads a variety of important medical research efforts at Kyoto University. Their research efforts span several decades, in two extremely different national contexts, but their recent international collaborations have reignited the profession over the last ten years.
2. Together, their cutting-edge research has helped make cancer immunology one of the most innovative branches in the field of medicine. Their current project, which focuses on mitigating negative immune regulation, has helped uncover new strategies for "inhibiting the brakes of our immune systems" through T-cell immunotherapy. Though cancer rates continue to decline throughout developed countries, it still remains the second leading cause of global mortality rates, contributing to millions of deaths each year. Thanks to their findings, many research initiatives, which had previously given up on the prospects of immunotherapy practices, are reinvesting hundreds of millions of dollars into an entirely new class of drugs that might help bring about lasting remissions in global cancer rates. Allison and Honjo were consequently deemed perfect candidates for a Nobel Prize because their research has not only broken barriers in the medical field, but eliminated borders in the fight against cancer, catalyzing cross-continental efforts to conquer the negative effects of this costly disease.
3. Cancerous tumors serve as some of the greatest antagonists within our immune systems, thwarting our body's ability to destroy foreign invaders. These cancerous tumors are particularly skilled at incapacitating our body's capacity to ward off malignant cells that spawn inside of us. Cancer, for reasons previously unknown to researchers, quickly excites our body's "molecular brakes “, which, in turn, lowers the effectiveness of our immune systems. For several decades, radiation therapy and standard chemotherapy were believed to be the only effectual approaches to mitigating the spread of cancer in the body. These classic therapies, however, are extremely harmful to human tissue, and they are often shadowed by toxic side effects. Cancer immunotherapy is therefore seen as a positive alternative that can reduce the likelihood of these crippling side effects. Cancer immunotherapy, in short, has become the more humane option for targeting our body's cancerous invaders.
4. All of this, however, would not have been possible without the nearly-thirty-year research campaigns carried out, separately at first, by Allison and Honjo. In the 1990s, Allison began monitoring a protein known as CTLA-4. CTLA-4 is located in the membranes of active T-cells, a type of white blood cell, behaving like an off switch for these "soldiers" within our immune systems. Allison's initial work in the early 1990s focused on ways to interfere with this off-switch and encourage these soldiers to return to the body's war against cancer. Around the same time, Honjo had been targeting another off-switch known as PD-1. PD-1 is a biological protector that limits our T-cells to overexposure; it prevents our immune system's soldiers from entering too many battles against foreign invaders. PD-1 is the "general" of the wars in our immune system that ensures that our T-cells do not become too exhausted. Some cancers intentionally try to attack this general, shutting down its capacity to command T-cells.
5. By the 2000s, Allison and Honjo's paradigm-shifting efforts had converged to find ways to (re)motivate the T-cell troops of our bodies through a new brand of cancer immunotherapy that targets both the effects CTLA-4 and PD-1. The result has been Nobel award-winning effort to conquer cancer through more amenable physiological measures.
6. And the world should be thankful -Allison and Honjo's medical practices are now on the forefront of eliminating the negative effects of melanoma, colorectal cancer, lung cancer, bladder cancer, and liver cancer. While these are just a few sources of foreign invasion, easing their effects is one step in the right direction for the medical industry's larger war on cancer.
Allison and Honjo began their most recent collaborative research in the
Rationale:
Allison and Honjo began their most recent collaborative research in the 2000s. Their cooperative efforts evolved from decades of individual research, converging in the 2000s to innovate cancer immunotherapy, specifically targeting CTLA-4 and PD-1, thus revolutionizing cancer treatment and improving immune response against malignancies. This collaboration marked a significant advancement in the fight against cancer.
A: 1970s Their collaborative research did not start in the 1970s, as both scientists were primarily focused on separate individual projects during that decade, laying the groundwork for future cooperation.
B: 1990s Although both researchers conducted significant work in the 1990s, their collaborative efforts did not begin until the 2000s, when their independent research started to converge effectively.
D: 1980s Their collaboration did not initiate in the 1980s, as both researchers were still developing their foundational studies, which only later culminated in a united research effort in the 2000s.
1. "They won't starve; if they're hungry enough, they'll eat." Parents of "picky" eaters hear this statement from well-meaning friends and fellow parents all the time. However, for parents of children with Avoidant Restrictive Food Intake Disorder or ARFID, the statement is untrue.
2. According to the National Eating Disorders Association (NEDA), between 0.5% and 5% of the general population may have ARFD. The disorder often affects young children and can be distinguished from simple pickiness; individuals with ARFD restrict their diet so severely, they suffer poor health as a result. In very severe cases, malnutrition and failure to thrive can occur.
3. ARFID is considered an eating disorder and a psychological condition; however, unlike other eating disorders such as anorexia and bulimia, people with ARFID do not restrict their food intake out of concern for their appearance or weight. Sufferers of ARFID limit their diet due to a lack of interest in food or out of a sense of extreme anxiety or fear around food and the process of eating (Eddy, n.d.).
4. While the causes of ARFID aren't yet well understood, traumatic events involving eating, such as a choking incident, a severe allergic reaction, or painful responses to food (cramping, diarrhea, or vomiting), can lead to worsening restrictive behavior. However, not all cases can be traced to such an incident. Children with ARFID may also suffer from sensory challenges that cause them to avoid certain food textures and flavors. Common comorbidities include ADHD, autism spectrum disorder, depression, and anxiety (Eddy, n.d.).
5. Attempting to pressure a child with ARFID to eat something they are uncomfortable with can heighten their anxiety around food and mealtimes. Instead, families of children with ARFID should seek treatment. Cognitive behavior therapy is the recommended treatment, though some patients may also need medication for anxiety or underlying physiological feeding issues. NEDA also notes that family-based therapy may be helpful for children with ARFID. Left untreated, ARFID can lead to serious physical health conditions in patients.
6. Multiple resources designed to help parents with children diagnosed with ARFID are available. NEDA lists a number of resources on its website, Additionally, numerous social media support groups have formed. One of the most notable resources is the Instagram feed of 8-year-old Hannah. Recently featured on ABC News, Hannah's Instagram, titled "My ARFD Life," shares videos of her experiences with foods. In a technique known as exposure therapy, Hannah is gradually introduced to new foods, exploring their texture. smell, and other features before eventually tasting them and sharing her reaction with her followers.
7. Like other mental health conditions, ARFID poses immense challenges to those who suffer from the disorder and to their families. The risks to physical and overall mental health can be scary, as well. Fortunately, as new information comes to light regarding this recently identified disorder, resources and professional knowledge have begun to increase. With proper care and support, patients with ARFID can drastically improve their quality of life.
Based on the information in the passage, a parent should seek medical intervention for a child's picky eating if the child:
Rationale:
B: A parent should seek medical intervention for a child's picky eating if the child is suffering physical effects from overly restrictive eating. ARFID can lead to serious health complications, including malnutrition and failure to thrive, making professional help crucial for their well-being and proper nutrition.
A: Refuses to try something the parent knows they like. This behavior reflects typical pickiness rather than the severe dietary restrictions associated with ARFID, which are more concerning.
C: Insists on having food presented in a certain way. While this might indicate a preference or sensory issue, it does not necessarily point to the harmful effects of ARFID that require intervention.
D: Throws a tantrum at meal time. Tantrums are common in many children and do not inherently signify the underlying issues of ARFID or the need for medical intervention.
The writer chose to use many vernacular expressions in his essay. Vernacular means
Rationale:
Vernacular means everyday language or expressions commonly spoken by people in a particular region or community. The writer's choice to use vernacular expressions enhances relatability and authenticity, allowing readers to connect with the content on a personal level.
A: blasphemous Referring to irreverent language or actions, this choice does not align with the context of common, relatable expressions intended to engage the audience.
C: ludicrous Pertaining to something absurd or laughable, this option fails to capture the essence of vernacular as it focuses on extreme, exaggerated forms of expression rather than everyday language.
D: ribald Relating to vulgar or indecent humor, this choice diverges from the notion of vernacular, which emphasizes familiarity and accessibility in communication rather than crudeness or explicitness.

The best title for this article is
Rationale:
D: Nobel Prize Winners Fight Cancer. This title accurately reflects the central theme of the article, highlighting the significant achievement of James P. Allison and Tasuku Honjo in winning the Nobel Prize for their revolutionary work in cancer immunotherapy, showcasing their efforts in combating cancer through innovative research.
A: Allison and Honjo Fight T-Cells. This option narrows the focus excessively on T-cells, overlooking the broader implications of their research and the significant impact on cancer treatment overall.
B: CTLA-4 and PD-1: Two Deadly Types of Cancer. This title misrepresents the content, as CTLA-4 and PD-1 are not types of cancer but rather immune checkpoint proteins targeted by Allison and Honjo's therapies.
C: Pharmacology and Cancer Treatments. While relevant, this title fails to capture the specific achievements of the Nobel laureates and their groundbreaking contributions to immunotherapy, making it too general.
1. In 2010, author Rebecca Skloot published The Immortal Life of Henrietta Lacks, the story of a Black woman who died of cervical cancer in 1951. The book, an immediate bestseller, examines the roles of race, class, gender, and ethics in medical research and considers the Implications, both positive and negative, of Henrietta Lacks's remarkable but inadvertent role in some of the most significant medical advances of the twentieth century.
2. In 1951, Lacks, a 30-year-old wife and mother of five, went to Johns Hopkins Hospital in Baltimore for treatment of cervical cancer. She was unable to pay for treatment and stayed in a segregated ward. During a procedure to place radium on her tumor, Lacks's doctor cut a sliver from the tumor, placed it in a petri dish, and handed it off to the lab assistant of George Gey, a Johns Hopkins cancer researcher. Sadly, cervical cancer is a particularly pernicious disease, and Henrietta succumbed in October 1951 after a brief but terribly painful struggle, leaving behind her young children.
3. George Gey had been trying unsuccessfully to grow human cells in culture-until Henrietta's cells arrived, Labeled HeLa, Henrietta's cancer cells doubled in culture within 24 hours - and they never stopped. Hela cells multiplied so rapidly and persistently, Gey eventually began giving them away to other researchers, According to Skloot, HeLa became the "workhorse" of research labs everywhere. They were used to test the polio vaccine and in the development of HIV medications and cancer treatments. HeLa cells were central to the development ofthe HPV vaccine and were some of the first human cells sent into space to determine how zero gravity affected human cellular activity.
The author of the passage probably included Henrietta's age and mentioned her young children in order to
Rationale:
Henrietta was a 30-year-old mother of five, which evokes sympathy for her situation and highlights the emotional impact of her cancer battle on her family. This personal detail invites readers to connect emotionally with her story, emphasizing the human cost of medical advancements derived from her cells.
A: suggest that Henrietta's age led to the immortality of her cells. Age does not correlate with cellular immortality; the focus is on her tragic story, not the biological implications of her age.
C: suggest that Henrietta's children might also have immortal cells. The passage does not imply any genetic transfer of cell characteristics to her children, focusing instead on the unique significance of Henrietta's cells.
D: point out how dangerous cancer is. While cancer's dangers are evident, the passage emphasizes Henrietta's personal narrative rather than solely addressing the severity of the disease itself.
1. As knowledge of climate change has expanded, so has the vocabulary surrounding the issue. Some key terms include greenhouse gas, fossil fuel, and carbon footprint. Understanding these terms can help us to recognize how changes in human activity can slow down climate change
2. The U.S. Environmental Protection Agency provides resources on its website to help citizens better understand climate change. Most people already know that the energy provided by the sun is key to life on earth. Greenhouse gases are substances that affect the way the earth either absorbs or reflects this energy. Water vapor and carbon dioxide are two examples of greenhouse gases. These gases absorb and hold some of the sun's energy, warming the planet like a "blanket" (Basics of Climate Change, 2023). This effect is similar to the way a greenhouse traps heat to support plant life, hence the term greenhouse effect
3. Greenhouse gases are important to regulating the earth's temperature and making the planet warm enough to sustain life. Natural occurrences such as plant and animal respiration, oceanic activity, and erupting volcanoes have always released greenhouse gases such as carbon dioxide When humans began extracting and burning fossil fuels such as coal, oil, and gas during the Industrial Revolution, greenhouse gas emissions rose sharply, upsetting the planet's balance and trapping too much heat. The result has been a sharp increase in the earth's temperature, leading to climate change. According to Dr. Julia Rosen, a geologist and journalist (2021), the average global temperature has risen 2:2 degrees Fahrenheit since 1880, with the sharpest temperature rise occurring in the last 70 years.
4. Use or plastics, especially single-use plastics, also enlarges the carbon footprint since the production of plastic requires the burning of fossil fuels and significant resulting carbon emissions. The average consumer can reduce their carbon footprint by making small changes such as recycling, reducing dependence on single use plastics, driving a fuel-efficient vehicle with lower emissions, and switching to renewable energy sources such as solar or wind energy.
5. While 2.2 degrees may not seem like much, we are seeing the effects of the earth's warming in the form of melting ice caps, rising sea levels, and more extreme weather events such as droughts, floods, and severe storms (Rosen, 2021). However, scientists agree that just as human activity caused climate change, so can human activity slow it down. Individuals, corporations, and governments can take steps to reduce greenhouse gas emissions by reducing dependence on fossil fuels. Understanding what contributes to our carbon footprint and taking measures to reduce it are the first steps.
Based on the reading passage, which county-wide policy would be most effective in reducing climate change?
Rationale:
Providing incentives for households that install solar or wind energy and reduce plastic consumption is the most effective county-wide policy for reducing climate change.
This option promotes renewable energy sources, which decrease reliance on fossil fuels, thus lowering greenhouse gas emissions. Additionally, reducing plastic consumption can significantly diminish carbon footprints, contributing to a collective effort to combat climate change effectively.
A: Mandate the use of energy-efficient appliances in all commercial buildings. This approach focuses solely on commercial energy efficiency, neglecting broader human activities and lifestyle changes essential for substantial climate impact.
B: Provide tax benefits for individuals who carpool and plant trees. While beneficial, this option addresses only specific behaviors and lacks the comprehensive approach needed to tackle the multifaceted issue of climate change.
D: Establish penalties for water usage over an established average level. This policy targets water conservation but does not directly address greenhouse gas emissions or the broader factors driving climate change.

Some vapes have been known to explode or catch fire, gravely injuring their users.
Based on how it is used in paragraph 4, synapses refer to the
Rationale:
Synapses refer to the connections between brain cells when something new is learned. The extract highlights that young people's brains build these connections faster, emphasizing the impact of nicotine on memory and learning processes.
A: chemicals present in vapes that make them particularly addictive. The passage focuses on synapses' role in learning, not on the chemical composition of vape products or their addictive qualities.
C: electrical mechanisms that make a vape function properly. The context centers on brain development and synapses, not the technical aspects or functioning of vaping devices themselves.
D: emotional feelings we get when our body is exposed to nicotine. Emotional responses are not mentioned in relation to synapses; the text discusses cognitive processes and development instead.
The athlete's performance required the application of his practical experiences. Application means
Rationale:
Application means putting to use. The context emphasizes the importance of utilizing practical experiences to enhance the athlete's performance, highlighting that effective application involves leveraging skills and knowledge in real scenarios.
A: making an attempt. This option suggests a trial without ensuring effective execution, which does not capture the essence of effectively utilizing experiences in performance.
B: putting into action. While similar, this phrase lacks the specificity of utilizing acquired experiences, focusing more on the act of execution rather than the context of application.
C: taking a risk. This option implies uncertainty and potential failure, which deviates from the notion of employing established practical experiences to enhance performance.
The computer file was compressed to save space. Compressed means made
Rationale:
Compressed means made more compact. In the context of file storage, compression reduces the file size by removing redundancies, allowing more data to fit in a smaller space, which is essential for efficient storage management.
A: less compact. This option contradicts the definition of compression, as its purpose is to increase compactness, not diminish it.
B: less exact. Compression does not inherently affect the precision of the data; it focuses primarily on reducing file size.
D: more exact. Increasing exactness suggests enhancing detail or precision, which is not relevant to the concept of file compression, where the goal is to decrease file size.
Choose the pair of words that represent synonyms.
Rationale:
Chastise - reproach are synonyms. Both words convey the idea of expressing disapproval or criticism towards someone, often in a corrective manner, highlighting their similarity in meaning and usage.
A: arduous - facile denote opposing concepts. Arduous signifies difficulty, while facile implies ease, creating a clear distinction between the two words rather than a synonym relationship.
C: tenacious - disparaging represent contrasting traits. Tenacious refers to determination and persistence, whereas disparaging conveys a sense of belittling or demeaning, illustrating a lack of similarity in meaning.
D: articulate - bumbling showcase differing characteristics. Articulate indicates clarity and fluency in expression, while bumbling suggests clumsiness or confusion in communication, highlighting their non-synonymous nature.
1. The 1960s and 1970s are often distinguished as hallmark decades for free speech and free expression in American history- the civil rights movement, feminist movement, and free speech movement all have their roots in the tumultuous Sixties and Seventies. As stated in Welner, Kim, and Biegel (2017), "In the 1960s and 1970s, free speech issues were at the forefront of education-related debates, with students asserting themselves in ways they never had before" (p. 33). The late 1960s and early 1970s were ripe with protest, specifically in response to the violent atrocities associated with the Vietnam War. Inevitably, this democratic fervor seeped into the systems and structures of K-12 public schooling. Thus, it is not surprising that this era gave birth to many of the modern constitutional debates regarding students and their First Amendment rights in public schools. In particular, this era gave birth to the landmark Supreme Court case known as Tinker v. Des Moines (1969).
2. Tinker v. Des Moines emerged from the countercultural milieu of the late Sixties: "In December 1965, a group of adults and students in Des Moines, lowa held a meeting. The group determined to publicize their objections to the hostilities in Vietnam and their support for a truce by wearing black armbands during the holiday season and by fasting on December 16 and New Year's Eve" (p. 43). Three students attending that meeting were John Tinker, 15 years old, Mary Beth Tinker, 13 years old, and Christopher Eckhardt, 16 years old. Fueled by the images they witnessed on television broadcasts, Tinker and her classmates decided to wear black armbands as a symbol of youthful resistance and patriotism. The administrators of the Des Moines Independent Community School District caught word of the upcoming protest and hastily adopted a school policy that promised to suspend any students who wore black armbands in protest of the Vietnam War. On December 16 and 17, the administration attempted to squash the public display of solidarity, all three students were suspended from school indefinitely "until they would come back without their armbands" (p. 43).
3. The students' parents fought back, suing the school for violating the children's right to free speech. After a U.S. district court - and later a U.S. court of appeals - ruled against the children and their families, citing that their protest was a disruption and breeched local school standards, the case made its way all the way to the U.S. Supreme Court. The resulting decision of Tinker v. Des Moines set in motion a historical tidal wave of praise and criticism. Promising that students do not "shed their constitutional rights to freedom of speech or expression at the schoolhouse gate," the Supreme Court justices decreed a 7-2 ruling in favor of the protestors. They claimed that the students' silent and symbolic expression was protected under the U.S. Constitution, citing that all political speech in public schools remains guarded by the First Amendment so long as it does not "substantially disrupt the learning environment." In a bold move for the times, the decision claimed that "In order for [a school] to justify prohibition of a particular expression of opinion, it must be able to show that its action was caused by something more than a mere desire to avoid the discomfort and unpleasantness that always accompany an unpopular viewpoint."

The Supreme Court Case Tinker v. Des Moines focused on
Rationale:
The Supreme Court Case Tinker v. Des Moines focused on free speech.
This case addressed the rights of students to engage in symbolic protest, affirming that their constitutional freedom of expression extends into public schools, provided it does not disrupt the educational environment. The ruling emphasized the importance of protecting political speech, especially regarding contentious issues like the Vietnam War.
A: labor laws. This option misrepresents the central theme of Tinker, as the case specifically revolved around students' rights rather than employment or workplace regulations.
C: the right to bear arms. This option diverges completely from Tinker’s focus on free speech, as it pertains to firearm ownership rather than expression or protest rights.
D: educational equity. Although related to school issues, this option overlooks the case's primary concern with freedom of speech, ignoring the significant context of political expression within educational settings.
1. The 1960s and 1970s are often distinguished as hallmark decades for free speech and free expression in American history- the civil rights movement, feminist movement, and free speech movement all have their roots in the tumultuous Sixties and Seventies.

Journaling, exercising, and crafting are examples of Which word should go in the blank?
Rationale:
Journaling, exercising, and crafting are examples of cathartic activities. These practices allow individuals to express emotions, release stress, and achieve mental clarity, contributing significantly to emotional well-being and personal growth.
