Select the meaning of the underlined word in the sentence.
Rationale:
The word 'labile' in the sentence refers to something that is likely to change or fluctuate rapidly. In the context provided, the child's labile condition indicates that the child's health is unstable or unpredictable, causing worry to the parents. 'Volatile' means liable to change rapidly and unpredictably, making it the correct interpretation of 'labile' in this sentence.
Photosynthesis is a process used by plants, algae, and certain bacteria to convert light energy into chemical energy stored in sugar molecules. This process is fundamental to life on Earth as it provides the primary source of energy for nearly all organisms. The energy is captured from sunlight by a pigment in the plants called chlorophyll, which gives plants their green color.
During photosynthesis, carbon dioxide from the air and water from the soil react in the presence of light to form sugars and oxygen. The oxygen is released into the atmosphere, which is crucial for the survival of most life forms on Earth. The sugars produced are used by the plant for energy and growth, storing excess energy as starch.
The process occurs in two main stages: the light-dependent reactions and the Calvin cycle. In the light-dependent reactions, energy from sunlight is absorbed by chlorophyll and converted into stored chemical energy in the form of ATP and NADPH. The Calvin cycle uses the ATP and NADPH produced in the light-dependent reactions to convert carbon dioxide into glucose.
Photosynthesis not only sustains plant life but also maintains the atmospheric oxygen levels and is a key factor in the carbon cycle, helping to regulate Earth's climate.
What is the primary function of photosynthesis?
Rationale:
The primary function of photosynthesis is to convert light energy into chemical energy stored in sugar molecules. During photosynthesis, plants, algae, and certain bacteria use sunlight to synthesize sugars from carbon dioxide and water. This process is essential for providing energy to nearly all organisms on Earth. While photosynthesis releases oxygen into the atmosphere as a byproduct, its main purpose is the conversion of light energy into chemical energy, making choice B the correct answer.

Photosynthesis not only sustains plant life but also maintains the atmospheric oxygen levels and is a key factor in the carbon cycle, helping to regulate Earth's climate.
What happens during the light-dependent reactions of photosynthesis?
Rationale:
During the light-dependent reactions of photosynthesis, light energy is absorbed by chlorophyll and converted into stored chemical energy. This energy is in the form of ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate), which are essential for the Calvin cycle to occur. Therefore, choice C, 'Light energy is converted into chemical energy,' is the correct answer as it describes the primary transformation that takes place in this phase of photosynthesis.
Have you ever wondered why the whistle of a traveling, distant locomotive predicts its approach several yards before anyone actually sees it? Or why an oncoming ambulance's screaming siren is heard momentarily several feet before the ambulance comes into full view, before it passes you, and why its siren is still heard faintly well after the ambulance is out of sight?
What you are witnessing is a scientific phenomenon known as the Doppler Effect. What takes place is truly remarkable. In both of these instances, when the train or ambulance moves toward the sound waves in front of it, the sound waves are pulled closer together and have a higher frequency. In either instance, the listener positioned in front of the moving object hears a higher pitch. The ambulance and locomotive are progressively moving away from the sound waves behind them, causing the waves to be farther apart and to have a lower frequency. These fast-approaching modes of transportation distance themselves past the listener, who hears a lower pitch.
What is the main idea of the passage?
Rationale:
The main idea of the passage is to explain the phenomenon of the Doppler Effect, which is demonstrated by the sound changes produced by a moving object like a train or an ambulance. As these objects approach a listener, the sound waves are compressed, resulting in a higher frequency and pitch. Conversely, as they move away, the waves are stretched, leading to a lower frequency and pitch. This effect is what causes the sound to be initially loud and then fade away after the object passes, as observed with the ambulance and locomotive.

Photosynthesis not only sustains plant life but also maintains the atmospheric oxygen levels and is a key factor in the carbon cycle, helping to regulate Earth's climate.
What would likely happen if chlorophyll were absent in plants?
Rationale:
If chlorophyll were absent in plants, they would not be able to capture light energy effectively. Chlorophyll is the pigment responsible for absorbing light energy during photosynthesis. Without chlorophyll, plants would lack the key component needed to convert light energy into chemical energy, resulting in a significant impairment of the photosynthesis process. This would lead to a decrease in the plant's ability to produce sugars and oxygen, ultimately impacting their growth and survival. Therefore, option B is the correct answer as the absence of chlorophyll would hinder the plant's ability to capture light energy efficiently.
Electrocardiogram
Beep!Ć¢Ä‚¬Ā¦Beep!Ć¢Ä‚¬Ā¦Beep! is the audible rhythmic sound made as the strength of the heart muscle is measured. The signal cadence has a characteristic record that varies in every individual. This record is called an electrocardiogram, or ECG.
In the body, an array of systemic neural responses constantly occur, emitting electric currents. The electric currents can be detected on the surface of the body, and if a person is hooked to an amplifier, these impulses are recorded by an electrocardiograph.
Most of the information obtained is about the heart because the heart sends out electric currents in waves. This Ć¢Ä‚¬Å“wave of excitationĆ¢Ä‚¬Ā¯ spreads through the heart wall and is accompanied by electric changes. The wave takes place in three distinct steps.
Initially, the Ć¢Ä‚¬Å“wave of excitationĆ¢Ä‚¬Ā¯ accompanied by an electric change lasts for approximately 1 to 2 seconds after the contraction of the cardiac muscle. The electric impulses are discharged rhythmically from the sinoatrial (SA) node, the pacemaker of the heart. This spread of excitation over the muscle of the atrium indicates that the atrium has contracted.
Next, the peak of the ECG reading is due to the atrioventricular (AV) node, causing the ventricle to become excited.
Finally, the ventricles relax, and any changes in the wave indicate to trained medical staff any abnormalities within the heart.
What is the best summary of the passage?
Rationale:
The passage discusses how the electrocardiogram (ECG) measures the 'wave of excitation' in the heart, detailing the three distinct steps from the SA node to the AV node. Option A is incorrect as it oversimplifies the process and does not focus on the ECG's specific function. Option B is partially correct but lacks the key point about the stages of excitation and the nodes involved. Option D is too general and does not highlight the specific process of the 'wave of excitation' as explained in the passage. Therefore, Option C is the best summary as it accurately reflects the systematic measurement and recording of the 'wave of excitation' within the heart by the ECG.
Blood Pressure Regulators
The body is composed of systems that have evolved and diversified in order to maintain the natural functions and processes they regulate. One such system that has these regulators is the bodyĆ¢Ä‚¬Ä„¢s cardiovascular system. The bodyĆ¢Ä‚¬Ä„¢s pump, which regulates the flow of vitally needed oxygen to all cells of the body, as well as the discard of carbon dioxide and other waste products, is the heart.
Because blood pressure varies at different points within the body, differing components are needed to keep the bodyĆ¢Ä‚¬Ä„¢s blood pressure regulated. Three of the basic components are baroreceptors, chemoreceptors, and the kidneys.
Baroreceptors are stretch receptors composed of fine branching nerve endings and are contained along the walls of the arteries near the heart and in other areas of the body as well. Impulses are related to this stretching along the arterial walls, which causes these baroreceptors to send out even more impulses to the heart, arteries, and veins, causing the blood pressure to go either up or down.
Chemoreceptors are located along the walls of the arteries and monitor changes in oxygen level, carbon dioxide, and pH. Just think! A fall in oxygen causes receptors to send impulses to raise the blood pressure.
The kidneys play a role in regulating blood pressure by absorbing salts and water and removing wastes. Hormones secreted by the adrenal cortex cause the kidney to keep or let go of any salt and water. This has an influence on blood volume and consequently on blood pressure.
Which statement is not a detail from the passage?
Rationale:
The correct answer is A because the statement incorrectly describes baroreceptors as rigid and static nerve endings when, in fact, they are stretch receptors composed of fine branching nerve endings. The passage clearly states that baroreceptors are stretch receptors along the arterial walls that send messages in response to stretching, not rigid and static. Choices B, C, and D are all accurate details from the passage regarding chemoreceptors, the kidneys' role in regulating blood pressure, and the heart's function in oxygen transport and waste removal, respectively.

What is the best summary of this passage?
Rationale:
Choice B provides the most comprehensive summary of the passage. It encapsulates the main points discussed, including the body's cardiovascular system, the role of baroreceptors, chemoreceptors, and the kidneys in regulating blood pressure. The other options focus on specific details mentioned in the passage but do not capture the broader scope of the content provided.
The federal government regulates dietary supplements through the United States Food and Drug Administration (FDA). The regulations for dietary supplements are not the same as those for prescription or over-the-counter drugs. In general, the regulations for dietary supplements are less strict.
To begin with, a manufacturer does not have to prove the safety and effectiveness of a dietary supplement before it is marketed. A manufacturer is permitted to say that a dietary supplement addresses a nutrient deficiency, supports health, or is linked to a particular body function (such as immunity), if there is research to support the claim. Such a claim must be followed by the words Ć¢Ä‚¬Å“This statement has not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.Ć¢Ä‚¬Ā¯
Also, manufacturers are expected to follow certain good manufacturing practices (GMPs) to ensure that dietary supplements are processed consistently and meet quality standards.
Requirements for GMPs went into effect in 2008 for large manufacturers and are being phased in for small manufacturers through 2010.
Once a dietary supplement is on the market, the FDA monitors safety and product information, such as label claims and package inserts. If it finds a product to be unsafe, it can take action against the manufacturer and/or distributor and may issue a warning or require that the product be removed from the marketplace. The Federal Trade Commission (FTC) is responsible for regulating product advertising; it requires that all information be truthful and not misleading.
The federal government has taken legal action against a number of dietary supplement promoters or Web sites that promote or sell dietary supplements because they have made false or deceptive statements about their products or because marketed products have proven to be unsafe.
What is the meaning of the phrase phased in as it is used in the third paragraph?
Rationale:
The phrase 'phased in' refers to a process that is implemented gradually or in stages over time. In the context of the paragraph, it means that the requirements for GMPs were gradually introduced for small manufacturers through 2010. This approach allows for a smoother transition and implementation of regulations without overwhelming all manufacturers at once. Therefore, the correct answer is C: 'implemented in stages.' Choices A, B, and D do not accurately reflect the meaning of 'phased in' in this context.
Subjective exams measure your ability in several areas. Besides recall information, you must be
able to realize content logically and intelligently express yourself in a clearly understood manner. Subjective test provide opportunity for students to show their broad knowledge of a subjective
area. Answers may be in the form of paragraphs or lengthy essays. When your review for an essay exam, concentrate on main ideas rather than details. Since essay tests are less to a few questions, they are likely to deal with more important ideas of a subject. Prepare a list of question you think might be asked. Write an answer to each of your questions. Rather than writing complete sentence down your thoughts in outline form. Doing so will help
you organize the information so that you can express yourself clearly.
When you take the test, read through all the questions before you start to write. Allot time for each question, spending more time for questions worth the most points. Read each question carefully to determine exactly what they are asked. Pay attention to words such as define, illustrate, explain, list, compare, and contrast. Each work requires a different type of response. Write a brief outline of your answer on scrap paper or the back of the test. Make sure you include all the important ideas that are within the limits of the question. In other words, do not write more than is asked for each answer. When you write your answer, keep it specific and as brief as possible. In the introductory sentence it is often helpful to make a general statement that includes
important points addressed in each question. Such a topic sentence serves as a framework for your answer. Then use your outline to develop the main point and subtopics. Add substance to
your answer by including as many facts as possible to support your answer.
Check your paper before you submit it. Look for mistakes in grammar, spelling, sentence
structure, and punctuation. Unless you are certain an answer is wrong, do not change it. Your answer is an educated guess and is usually your best chance of answering correctly

This approach also helps in organizing thoughts and presenting a clear and coherent response to the question, which is crucial in subjective assessments where logical expression plays a significant role.
The Electoral College has nothing to do with college and contains no students. The Electoral
College consists of votes that each state acquires based on the number of representatives it has in Congress. Each state has two electoral votes because each state has two senators. The remaining electoral votes are determined by the number of Congressmen, the number of which is based on the
population of the state established by the Census taken each decade.
During the presidential election, most states cast all their electoral votes for the candidate who
wins the popular vote in that state. ItĆ¢Ä‚¬Ä„¢s all very confusing, but the founding fathers know what they were doing. By having and using the Electoral College candidatesĆ¢Ä‚¬Ä„¢ campaign in every state, but just because they win the popular vote across the country doesn't mean they will always win the election. Case in point, in election 2000, Al Gore won the popular vote across the country,
but George W. Bush won more electoral votes. Therefore, he became our 43rd president.
Which statement from the passage is a fact?
Rationale:
The correct answer is A. The passage mentions that during the presidential election, most states cast all their electoral votes for the candidate who wins the popular vote in that state. This is a fact based on how the Electoral College operates. B is incorrect as the electoral votes are not randomly assigned but are based on the number of representatives each state has in Congress. C is not supported by the passage as it does not state candidates only campaign in states where they think they can win. D is incorrect as the passage explicitly states that the Electoral College has nothing to do with a college in Washington D.C.

The Game of Bridge
The ebb and flow of laughter and silence fills the room as
four old friends gather to engage in a round of Bridge
playing. For the beginner, Bridge can be complicated, but
with time, effort, and a good teacher, even the novice can
become proficient.
Composed of two main parts, bidding and playing, Bridge
requires the player's undivided attention. The dealer deals
the entire deck of playing cards evenly between the for
players, with each person receiving thirteen cards. In the
bidding portion of the game, the four suits of cards in the
deck are ranked highest to lowest as follows:
spades, hearts, diamonds, and finally clubs. However,
during play all the suits of cards are considered equals,
and they go from highest to lowest from the ace being
high to the two cards being low. The highest number of
tricks wins. A trick is one card played by each player for a
total of four. After the lead player lays down his/her card,
the other players follow suit, if possible. The highest card
within the four "same suit" cards played wins the trick
and picks up all four cards. If a player cannot follow suit,
he/she plays any card, but to make the game more
interesting and challenging, one suit is named a trump suit
which means that if a player plays a card from the trump
suit, it always wins the trick. If two cards from the trump
suit are played, the highest card within the trump suit
wins the trick. Obviously, the team with the most tricks
wins the hand.
How does the author want the reader to feel?
Rationale:
The author aims to convey a positive and encouraging tone towards learning the game of Bridge. Throughout the passage, the author emphasizes that with time, effort, and a good teacher, even novices can become proficient in Bridge. The descriptions of the game mechanics and the mention of becoming proficient suggest that the author wants readers to feel confident and excited about learning and mastering Bridge, making choice C, 'Confident and excited about learning the game of Bridge,' the correct answer.

The bodyĆ¢Ä‚¬Ä„¢s pump, which regulates the flow of vitally needed oxygen to all cells of the body, as well as the discard of carbon dioxide and other waste products, is the heart.
Because blood pressure varies at different points within the body, differing components are needed to keep the bodyĆ¢Ä‚¬Ä„¢s blood pressure regulated. Three of the basic components are baroreceptors, chemoreceptors, and the kidneys.
Baroreceptors are stretch receptors composed of fine branching nerve endings and are contained along the walls of the arteries near the heart and in other areas of the body as well. Impulses are related to this stretching along the arterial walls, which causes these baroreceptors to send out even more impulses to the heart, arteries, and veins, causing the blood pressure to go either up or down.
Chemoreceptors are located along the walls of the arteries and monitor changes in oxygen level, carbon dioxide, and pH. Just think! A fall in oxygen causes receptors to send impulses to raise the blood pressure.
The kidneys play a role in regulating blood pressure by absorbing salts and water and removing wastes. Hormones secreted by the adrenal cortex cause the kidney to keep or let go of any salt and water. This has an influence on blood volume and consequently on blood pressure.
Which statement is not a detail from the passage?
Rationale:
The correct answer is A because the statement incorrectly describes baroreceptors as 'rigid and static,' whereas the passage describes them as 'stretch receptors composed of fine branching nerve endings.' The passage details that baroreceptors are contained along the walls of the arteries near the heart and in other areas of the body, and they send out messages related to stretching along the arterial walls. Choices B, C, and D are all details directly supported by the passage, making them incorrect answers to the question.

What is the primary purpose of the writer in this passage?
Rationale:
The primary purpose of the writer in this passage is to inform the reader about how the cardiovascular system regulates blood pressure. The passage discusses the different components involved in regulating blood pressure, such as baroreceptors, chemoreceptors, and the kidneys. It explains their roles in maintaining blood pressure levels within the body. There is no direct focus on dangers of high blood pressure, heart attack risks, or persuading the reader to control blood pressure, making option C the correct choice.
The immune system is a network of cells, tissues, and organs that defends the body against attacks by foreign invaders. These invaders are primarily microbesĆ¢Ä‚¬Ä€¯tiny organisms such as bacteria, parasites, and fungiĆ¢Ä‚¬Ä€¯that can cause infections. Viruses also cause infections, but are too primitive to be classified as living organisms. The human body provides an ideal environment for many microbes. It is the immune systemĆ¢Ä‚¬Ä„¢s job to keep the microbes out or destroy them.
The immune system is amazingly complex. It can recognize and remember millions of different enemies, and it can secrete fluids and cells to wipe out nearly all of them. The secret to its success is an elaborate and dynamic communications network. Millions of cells, organized into sets and subsets, gather and transfer information in response to an infection. Once immune cells receive the alarm, they produce powerful chemicals that help to regulate their own growth and behavior, enlist other immune cells, and direct the new recruits to trouble spots.
Although scientists have learned much about the immune system, they continue to puzzle over how the body destroys invading microbes, infected cells, and tumors without harming healthy tissues. New technologies for identifying individual immune cells are now allowing scientists to determine quickly which targets are triggering an immune response.
Improvements in microscopy are permitting the first-ever observations of living B cells, T cells, and other cells as they interact within lymph nodes and other body tissues.
In addition, scientists are rapidly unraveling the genetic blueprints that direct the human immune response, as well as those that dictate the biology of bacteria, viruses, and parasites. The combination of new technology with expanded genetic information will no doubt reveal even more about how the body protects itself from disease.
What is the meaning of the word 'enlist' as it is used in the second paragraph?
Rationale:
In the second paragraph, 'enlist' is used in the context of immune cells responding to an infection by calling other immune cells into service to address the issue. Therefore, the correct meaning of 'enlist' in this context is 'call into service.' The immune system works by activating and directing different cells to combat threats, highlighting the importance of mobilizing immune cells into action to fight infections.
THE Farallon Island, or devils Teeth, as they are referred to by sailors, area group of small islands with rocky, barren terrain and treacherous, 48 km (30 miles) off the coast of San Francisco, California although the islands are small, with a combined total land area of 0.41km squared (0.16 square miles), they are positioned in a major ocean current, which enables them to house dense populations of birds, rodents seals, and other water mammals.
The abundance of wildlife first attracted Russian and American fur traders in the early 1800s, who then nearly eliminated the seal population in the area. The islands then became an agricultural resource for San Francisco during the gold rush era when egg companies began harvesting bird eggs on the islands. In 1863, violence between viral egg companies erupted on the islands (known as the Egg War") which inadvertently attracted national attention and provoked lawmakers to pass legislation to protect and rehabilitate the island's natural ecosystem.
In 1881, an executive order was passed that decreed egging illegal on the Farallon's. This ended private enterprises on the islands was reinforced in 1909 when President Theodore Roosevelt created the Farallon Reservation to restore human access and preserve that northern island, and over time many of the island original inhabitants have returned.
The Farallon's are now home to the world's largest population of western gull. Seals have returned, as well as otters and sea lions, which in turn attracts great white sharks. The combination of sharks, underwater currents, and jagged coastline are probably what earned the Farallon's their nickname "Devil's Teeth," though it hasn't stopped a few adventurous people from swimming. Four people have completed the 30-mile swim from the islands to San Francisco; the fastest person completed the journey in 14 hours.
What is the main idea of the passage?
Rationale:
The correct answer is C. The passage discusses how human activities, such as fur trading and egg harvesting, disrupted the ecosystem of the Farallon Islands in the early 1800s. This disruption led to the near elimination of seals and other wildlife populations. However, due to national attention and legislative action, efforts were made to protect and rehabilitate the island's natural ecosystem. The passage highlights the restoration efforts that took place over time, showcasing how humans played a role in both disrupting and restoring the ecosystem of the Farallon Islands.

Which of the following is a credible source that the author might have consulted to help write the article?
Rationale:
Choice D is the correct answer as it suggests consulting a story published by the Fish and Wildlife Service, originally written by a former refuge manager. This source would provide reliable information on the Farallon Islands' natural ecosystem, wildlife conservation efforts, and historical context. The Fish and Wildlife Service is a reputable organization known for its expertise in wildlife management and conservation, making their publications a credible source for an article on the Farallon Islands. Options A and B are less relevant to the topic and would not offer in-depth insights into the specific subject matter discussed in the article.

Which of the following pieces of evidence does the author use to speculate why the Farallon Islands are called 'The Devil's Teeth'?
Rationale:
The author mentions that the Farallon Islands are home to sharks, otters, sea lions, and seals, which attract great white sharks. Additionally, the combination of sharks, underwater currents, and a jagged coastline are probably what earned the islands the nickname 'Devil's Teeth.' This evidence supports choice A, as it directly links the presence of sharks, choppy currents, and a jagged coastline to the speculated reason behind the islands' nickname.
It can be difficult to write sometimes, especially if you are creating something brand new. It is even harder when you must write while following certain rules. Some writers thrive when there are limits, like sonnets or elegies; you can't just throw some words on the page and call it a haiku. On the other hand, some successful poets really enjoy breaking the rules. They will refuse to use the rules, if you can just break them and still so then what good are the rules, if you can just break them and still succeed? That doesn't make sense. I guess that is why I am not a poet.
Based on the author's supports and evidence, which of the following is a valid evaluation of the paragraph?
Rationale:
The paragraph reflects a personal perspective on writing styles and rules. The author discusses the challenges and preferences of writers, highlighting the contrast between those who adhere to rules and those who break them. The final statement, 'That doesn't make sense. I guess that is why I am not a poet,' indicates a personal bias and opinion, suggesting that the text is more of an entertaining piece rather than a logical argument, a scholarly analysis, or a part of an academic essay.

In 1932, the Australian government lost war against the native emu population. the operation that has since become known as great emu war began as an initiative to combat overpopulation of the crop-destroying birds invading farmland around Chandler and Walgooglan. The initial assault on the flightless avian began November 2 and lasted six days before the military personnel withdrew. efforts resumed on November 12, but by early December, the feathered foes had adopted guerrilla tactics against the targeted wheat fields, rendering military involvement largely ineffective. The Australian government declined further involvement with the ongoing conflict in 1934, 1943, and 1948, despite repeated pleas for assistance by the farmers in the area.
Which of the following statements is a logical conclusion based on this report?
Rationale:
The report details the unsuccessful attempts by the Australian government to combat the emu population from 1932. Despite military involvement in the Great Emu War, the emus adapted guerrilla tactics, rendering the efforts largely ineffective. The government declined further involvement with the ongoing conflict in 1934, 1943, and 1948. Therefore, the logical conclusion based on this report is that emus continued to destroy crops in the area through the 1930s and 1940s, as there is no indication of successful eradication or control of the emu population during this period.

Blue whales can reach can reach a length of 98 ft long can weigh as much as 198 tons. however, in the blue Mountains of eastern Oregon, there is an organism currently covering an area of 3 square miles and estimated to weigh at least 7 500 tons: the Armillaria Ostayae fungus, Though A. Ostoyae is found in other places, such as Michigan and Germany, only Oregon's fungus has grown to such an enormous size. The humongous fungus is estimated to be anywhere from 2000 to 8000 years old, and it continues to grow by 1 to 3 feet every year.
What is the main purpose of the passage?
Rationale:
The correct answer is 'B: To inform.' The passage presents factual information about the Armillaria Ostoyae fungus, its characteristics, and its unique features in Oregon. It aims to educate readers about this remarkable organism and its impressive size and age. There is no attempt to entertain, persuade, or solely describe the fungus without providing informative content, making 'to inform' the most suitable purpose of the passage.
Bessie Coleman, the first civilian licensed black pilot in the world, was born in 1892 to sharecroppers in Texas, where she attended a segregated school and worked with her family in the cotton fields. She dreamed of becoming a pilot but no flight school in America would accept her, so she moved to France to earn her pilot's license. When she returned to the U.S, she wanted to open a flight school for Black students. She became a stunt flier and performance for paying audiences, which she insisted be desegregated.

On February 2 of each year, the United States observes the unusual holiday of Groundhog Day of hope that winter is over and spring is beginning. this tradition has been officially observed in the US since the 1800s and is believed to have developed from European folk traditions in which a bear, fox badger or even hedgehog would serve as the symbolic meteorologist, although other cultures and towns observe Groundhog Day ( or something similar) the town of Punxsutawney, Pennsylvania takes special pride in being home to the one true forecasting groundhog, Punxsutawney Phil. At the turn of the twentieth century, townspeople formed the Punxsutawney GroundHog Day. Over the years, these events have come to include a scavenger hunt, a talent show, and a ball.
Legend has it that on Groundhog Day official weather forecasting grounding awakens from hibernation and comes out of his burrow to look for his shadow. If he sees his shadow, six more weeks of winter are to come, and Punxsutawney Phill takes this as a sign that spring has arrived, and he remains above ground. of course, common sense tells us that February 2 is too early for spring to begin and that while humans might learn, they are unlikely to act on their instincts based on a schedule set by the Gregorian Calendar, nevertheless, a visit to Pennsylvania to see Punxsutawney Phil and all of the fun he inspires each year might just provide the touch of hope needed to reach the end of writer.
Which of the following pairs of search terms entered into a search engine with the phrase 'Groundhog Day' is likely to produce information about the origin of Groundhog Day?
Rationale:
The correct answer is 'A: History and folklore.' When researching the origin of Groundhog Day, terms related to history and folklore are likely to yield information about the traditions, beliefs, and historical background associated with the holiday. In this context, understanding the historical and folkloric aspects of Groundhog Day can shed light on how and why the tradition originated and evolved over time. Terms like 'holiday and festivities' (choice B) may focus more on the celebration aspects, 'habitat and diet' (choice C) on the animal itself, and 'weather and farming' (choice D) on related but different topics, making them less relevant to uncovering the origin of Groundhog Day.

Blood Pressure.The heart produces a characteristic "lub-dub" sound, which results from the rapid contraction and relaxation of its chambers. Each contraction, known as ventricular contraction, ejects approximately 70 mL of blood into the vascular system, which varies in volume and pressure. Blood pressure specifically refers to the pressure within the arterial system, commonly measured at the brachial artery in the arm, as pressure levels can differ at various points along the circulatory pathway. Essentially, blood pressure is the force exerted by blood in all directions within a specific area, driving the flow of blood from the heart, throughout the body, and back again. It is typically expressed as a ratio of systolic pressure over diastolic pressure. Systolic pressure, or the "high peak" pressure, occurs when the ventricles contract and push blood into the arteries, while diastolic pressure, or the "low peak" pressure, is the pressure in the arteries just before the next contraction. An increase in blood pressure may arise if arterial walls lose some elasticity due to aging or disease.
Which of the following statements is not supported by the passage?
Rationale:
The correct answer is D. The passage states that an increase in blood pressure can occur if the arterial walls lose some of their elasticity due to age or disease, not necessarily always by disease. Therefore, the statement that loss of arterial wall elasticity is always caused by disease is not supported by the passage. Choices A, B, and C are all facts supported by the information provided in the passage.
Doppler Effect
Have you ever wondered why the whistle of a traveling, distant locomotive predicts its approach several yards before anyone actually sees it? Or why an oncoming ambulanceÄ€™s screaming siren is heard momentarily several feet before the ambulance comes into full view, before it passes you, and why its siren is still heard faintly well after the ambulance is out of sight?
What you are witnessing is a scientific phenomenon known as the Doppler Effect. What takes place is truly remarkable. In both of these instances, when the train or ambulance moves toward the sound waves in front of it, the sound waves are pulled closer together and have a higher frequency. In either instance, the listener positioned in front of the moving object hears a higher pitch. The ambulance and locomotive are progressively moving away from the sound waves behind them, causing the waves to be farther apart and to have a lower frequency. These fast-approaching modes of transportation distance themselves past the listener, who hears a lower pitch.
What is the author's primary purpose in discussing the Doppler Effect in this essay?
Rationale:
The author's primary purpose in writing the essay about the Doppler Effect is to inform the reader about how movement affects sound. The essay explains the scientific phenomenon of the Doppler Effect and how it influences the perception of sound when objects like trains and ambulances are in motion. The focus is on how the movement of these objects toward or away from the listener alters the frequency and pitch of the sound waves. The essay aims to educate the reader on this specific aspect of physics rather than entertain or analyze differences between train and ambulance sounds.
The Moon has been worshipped by primitive peoples and has inspired humans to create everything from lunar calendars to love sonnets. But what do we really know about it? The most accepted theory about the Moon's origin is that it was formed from the debris of a massive collision with the young Earth about 4.6 billion years ago. A huge body, perhaps the size of Mars, struck the Earth, throwing out an immense amount of debris that coalesced and cooled in orbit around the Earth.The development of Earth is inextricably linked to the Moon; the Moon's gravitational influence upon the Earth is the primary cause of ocean tides. In fact, the Moon has more than twice the effect on the tides than the Sun. The Moon makes one rotation and completes a revolution around the Earth every 27 days, 7 hours, and 43 minutes. This synchronous rotation is caused by an uneven distribution of mass in the Moon (essentially, it is heavier on one side than the other) and has allowed the Earth's gravity to keep one side of the Moon permanently facing Earth.The average distance from Earth to the Moon is about 384,403 km. The Moon has no atmosphere; without it, the Moon has no protection from meteorite impacts, resulting in a surface covered with impact craters, both large and small. The Moon also has no active tectonic or volcanic activity, so the erosive effects of atmospheric weathering, tectonic shifts, and volcanic upheavals that tend to erase and reform the Earth’s surface features are not at work on the Moon. In fact, even tiny surface features, such as the footprint left by an astronaut in the lunar soil, are likely to last for millions of years unless obliterated by a chance meteorite strike. The surface gravity of the Moon is about one-sixth that of Earth's. Therefore, a person weighing 82 kilograms on Earth would only weigh 14 kilograms on the Moon. The geographical features of the Earth most similar to those of the Moon are places such as the Hawaiian volcanic craters and the huge meteor crater in Arizona. However, the climate of the Moon is very different from either Hawaii or Arizona; in fact, the temperature on the Moon ranges from 123 degrees Celsius to -233 degrees Celsius.
What is the passage primarily about?
Rationale:
The passage primarily discusses various aspects of the Moon, what is known about it, and how it differs from Earth. It covers topics such as the Moon's formation, gravitational influence on Earth, lack of atmosphere, surface features, gravity, and climate. While it mentions the Moon's origin and its effect on Earth, the main focus is on providing information about the Moon and highlighting its distinctions from Earth.
Subjective exams measure your ability in several areas. Besides recall information, you must be
able to realize content logically and intelligently express yourself in a clearly understood manner. Subjective test provide opportunity for students to show their broad knowledge of a subjective
area. Answers may be in the form of paragraphs or lengthy essays. When your review for an essay exam, concentrate on main ideas rather than details. Since essay tests are less to a few questions, they are likely to deal with more important ideas of a subject. Prepare a list of question you think might be asked. Write an answer to each of your questions. Rather than writing complete sentence down your thoughts in outline form. Doing so will help
you organize the information so that you can express yourself clearly.
When you take the test, read through all the questions before you start to write. Allot time for each question, spending more time for questions worth the most points. Read each question carefully to determine exactly what they are asked. Pay attention to words such as define, illustrate, explain, list, compare, and contrast. Each work requires a different type of response. Write a brief outline of your answer on scrap paper or the back of the test. Make sure you include all the important ideas that are within the limits of the question. In other words, do not write more than is asked for each answer. When you write your answer, keep it specific and as brief as possible. In the introductory sentence it is often helpful to make a general statement that includes
important points addressed in each question. Such a topic sentence serves as a framework for your answer. Then use your outline to develop the main point and subtopics. Add substance to
your answer by including as many facts as possible to support your answer.
Check your paper before you submit it. Look for mistakes in grammar, spelling, sentence
structure, and punctuation. Unless you are certain an answer is wrong, do not change it. Your answer is an educated guess and is usually your best chance of answering correctly.

Croatian-born inventor Nikola Tesla is often called the "forgotten scientist". Although he
invented the alternating current (AC) motor and developed an AC electricity generation system, he never received historical credit for many of his achievements, unlike one of his first employer and eventual nemesis, inventor Thomas Edison
Tesla made the first sketches of his idea for a brushless of his idea for a brushless AC motor while he was a student at the University of Prague in 1882. His interest in electricity generation led him to Paris where he was employed by the Continental Edison Company later that year to repair Edison's direct current (DC) power plants. Two years later, Tesla immigrated to New York City and acquired a job as an engineer at
Thomas Edison's headquarters in Manhattan. Edison was impressed with Tesla's work ethic and
ingenuity. He challenged the young scientist to develop an improved design for his DC
generators for $50,000. Tesla experimented for months, finally presenting Edison with the
solution he needed. Edison reneged on the deal, telling Tesla that he didn't understand American humor. Tesla soon left Edison in order to begin his own electric light company
Tesla filed and was granted more than 30 patents for his inventions in 1887 and 1888. He soon
had financial backing for his ideas from one of Edison' main competitors, Westinghouse. In the
1890's Tesla experimented with x-rays, developed a high-voltage electrical transformer call the
Tesla coil, and demonstrated the propagation of radio waves two years before the "Father of
Radio" Guglielmo Marconi. He was also the first to harness the mammoth potential energy of
Niagara Falls. He worked with General Electric to install AC generators with turbines driven by the falling waters of the Niagara River, creating the first modern power plant although a brilliant scientist, Tesla was not an astute businessman. He created his own obscurity by relinquishing
royalty rights for his inventions to major corporations for the purpose of raising funds for future projects.
What did Tesla accomplish while attending the University of Prague?
Rationale:
While attending the University of Prague, Tesla made designs for a brushless alternating current motor. This innovation marked the beginning of his groundbreaking work in the field of electricity and laid the foundation for his future achievements. Tesla's early sketches and ideas for the AC motor at the University of Prague set him on a path that would ultimately revolutionize the way electricity was generated and utilized.

What is the meaning of the word 'astute' in the last paragraph?
Rationale:
The correct answer is B: 'Shrewd.' In the context provided, the word 'astute' describes someone who is clever, perceptive, and shows keen judgment. The text mentions that although Tesla was a brilliant scientist, he was not an astute businessman, indicating that he lacked the shrewdness or sharp business acumen required to navigate the commercial aspects of his inventions successfully. This is further supported by the statement that Tesla relinquished royalty rights for his inventions to major corporations to raise funds for future projects, showcasing a lack of business savvy.

generators for $50,000. Tesla experimented for months, finally presenting Edison with the
solution he needed. Edison reneged on the deal, telling Tesla that he didn't understand American humor. Tesla soon left Edison in order to begin his own electric light company
Tesla filed and was granted more than 30 patents for his inventions in 1887 and 1888. He soon
had financial backing for his ideas from one of Edison' main competitors, Westinghouse. In the
1890's Tesla experimented with x-rays, developed a high-voltage electrical transformer call the
Tesla coil, and demonstrated the propagation of radio waves two years before the "Father of
Radio" Guglielmo Marconi. He was also the first to harness the mammoth potential energy of
Niagara Falls. He worked with General Electric to install AC generators with turbines driven by the falling waters of the Niagara River, creating the first modern power plant although a brilliant scientist, Tesla was not an astute businessman. He created his own obscurity by relinquishing
royalty rights for his inventions to major corporations for the purpose of raising funds for future projects.
What word means the same as relinquishing as it is used in the last paragraph?
Rationale:
The word 'relinquishing' means giving up or surrendering something. In the context provided, Tesla relinquished his royalty rights for his inventions to major corporations. Therefore, the correct synonym for relinquishing in this case is 'Surrendering,' making it the correct answer choice.
About 6% of the earth is covered by rainforests. The largest rainforest in the world is the
Amazon Basin, which stretches over 2.3 million square miles in nine different South American countries. This area is double the length of all the other remaining rainforests in the world. Brazil contains 60%of the Amazonian rainforest, since it lies at the mouth of the river Amazon. This river is the second largest in the world and contains more than one-fifth of the world's fresh water. The Amazon rainforest is a type of wet broadleaf forest. The weather there is very humid and warm as it rains quite a bit. Because of the high rainfall, the forest is very rich and green. The
tree leaves are pointed and narrow so that the raindrops can easily drop off wet plants. This
tropical rainforest has more living species than the entire European continent. There are over 400 types of insects living in one single rain forest tree for a total of 2.5 million species. One square kilometer of rainforest may contain over 75,000 types of trees and approximately 438,000
different kinds of plants, which comes to a total of 90,000 tons of greenery overall. The Amazon rainforest is home to 2,000 birds and mammals, with one in every five birds in the world living there. Local farmers have lived off this rich and diverse land for thousands of years. They have been able to find food and water here without destroying the land. The Kayapo people of Brazil
farm in an environmentally-friendly way. Instead of chemicals, they use burned wood to enrich the soil, and plant banana trees, which attract wasps. These wasps then feed on leafcutter ants and get rid of these harmful insects. The rainforest also offers a lot of tropical fruits, such as bananas and coconuts, as food.
Cinnamon is made from the bark of a rainforest tree. Amazonian Indians use the fruit and stem
of the Buruti plant as a drink, to make bread and to build houses. Many other plants are used as medicine. But the Amazon rainforest is in very big danger of disappearing. 9,169 square miles of
forest have been cut down in 2003 in Brazil alone. An area of the size of a football field is burned down basically every minute, which means that the rain forest may be gone by the year 2030.The dangers related to this type of activity are obvious. Trees take in poisonous carbon
dioxide from the air and give off oxygen. There is more oxygen and less carbon dioxide around a
rainforest. When trees are cut down, however, the amount of carbon dioxide increases, and the
air gets warmer. This leads to global warming, which is extremely harmful to the environment. It
is estimated that the burning of Brazilian rainforests alone produces 200 million metric tons of carbon dioxide ayear. Another danger connected with destroying the rainforest is the disappearance of plants and animals. When trees are cut down, plants and animals have no more
food left and slowly die out. Killing wild animals is illegal in Brazil, but there is plenty of stealing going on. 38 million animals are stolen and sold illegally each year. The most hunted
animals are birds, especially parrots, followed by snakes and the jaguar.
How can you describe the Amazon rainforest?
Rationale:
The correct answer is A. The Amazon rainforest is characterized by high rainfall, which keeps the forest lush and green. The text mentions that the weather is very humid and warm due to frequent rain, leading to a rich and green forest. Additionally, it describes how the tree leaves are shaped to allow raindrops to easily fall off wet plants, highlighting the adaptation to the high rainfall in the region.

What is referred to as 'rich and diverse land' at the beginning of paragraph 3?
Rationale:
In the text provided, the author mentions that the Amazon rainforest is home to 2,000 birds and mammals, which is an illustration of the rich and diverse ecosystem within the area. This information directly corresponds to the statement about the 'rich and diverse land' at the beginning of paragraph 3. Therefore, the correct answer is option B, as it aligns with the specific details presented in the text.

Which rainforest plant has more than one use?
Rationale:
The correct answer is D, the Buriti plant. The passage mentions that Amazonian Indians use the fruit and stem of the Buriti plant as a drink, to make bread, and to build houses. This plant demonstrates multiple uses within the rainforest ecosystem, making it the plant with more than one use among the options provided.
It is a well-known fact that it takes the Earth approximately 365 days to orbit the Sun. At the same time, the Earth revolves or spins around itself over the course of 24 hours, which explains why we experience day and night. One half of the Earth is always facing the Sun, while the other half is facing away. As a result, different time zones divide the globe. Moving suddenly from one time zone to another, such as when flying from Asia to North America, can cause jet lag. People often feel tired, wake up suddenly during the night, and cannot return to sleep. It takes time to adjust to a new time zone. Another important factor to consider is the slight tilt of the Earth toward the Sun. The Earth does not stand straight but leans slightly to one side. Therefore, when it revolves around the Sun, the middle part of the Earth is always closer to the Sun and receives more heat. This area is called the equator, and the regions above and below it are known as the tropics. Countries located in the tropics receive a consistent amount of daylight throughout the year, with the Sun rising at 6 AM and setting at 6 PM. In contrast, the tips of the Earth, or the poles, receive hardly any light because they are so far from the Sun. There are two main seasons at the poles: 6 months of summer, when the Sun is always shining (even at night), and 6 months of winter, characterized by constant darkness. Between the tropics and the poles lies the temperate zone, where there are four distinct seasons. The Sun rises and sets at different times throughout the year. In spring and summer, it gets light earlier; in fall and winter, it gets dark earlier. People living in temperate zones take advantage of this variation to maximize their daylight exposure. At the beginning of spring, countries in Europe and North America readjust their clocks by moving them an hour ahead. As a result, the Sun does not set around 7 or 8 PM as usual, but an hour later. This practice is called Daylight Savings Time (DST) and lasts until the beginning of fall, when people move their clocks back one hour to Standard or Regular Time. It is believed that Benjamin Franklin first suggested the introduction of Daylight Savings Time in the 18th century, but the first serious proposal came in 1907 from William Willet. However, his idea was shelved by the British government, which deemed it unnecessary. Daylight Savings Time was first implemented by the German government in 1916 in order to save energy during World War I. Shortly after, the United Kingdom followed suit, with the United States doing the same in 1918. The law was unpopular, as people had to wake up earlier, leading many to experience a feeling similar to jet lag. However, the energy crisis of the 1970s forced the U.S. to establish Daylight Savings Time as law. Studies showed that the introduction of Daylight Savings Time in the spring saved the U.S. 10,000 barrels of oil per day between 1974 and 1975. It also prevented 2,000 traffic injuries and 50 traffic-related deaths, saving the country $28 million. Currently, Americans switch to Daylight Savings Time on the first Sunday in April and revert to Standard Time on the last Sunday in October. As of 2007, the time adjustments occur even earlier in March and November.
What does the sentence ‘It takes time to get used to a new time zone’ mean in paragraph 1?
Rationale:
The sentence ‘It takes time to get used to a new time zone.’ in paragraph 1 refers to the fact that changing time zones causes jetlag, making people feel tired, waking up suddenly during the night, and having difficulties sleeping. This adjustment period is needed for the body to adapt to the new time zone.

If it is 7 p.m. Standard Time, what time is it for Daylight Savings Time?
Rationale:
When transitioning from Standard Time to Daylight Savings Time, the clock is moved forward by one hour. Therefore, if it is 7 p.m. Standard Time, it would be 8 p.m. in Daylight Savings Time. The correct answer is 6 p.m., reflecting the advancement of the clock by one hour during the Daylight Savings Time period.

What can be inferred about Daylight Savings Time?
Rationale:
The correct answer is A: "It will be modified starting in 2007." The passage mentions that as of 2007, the time readjustment for Daylight Savings Time will happen even earlier, in March and November. This implies that there will be modifications to the timing of Daylight Savings Time starting in 2007, aligning with the information provided in the passage about the changes in the timing of Daylight Savings Time adjustments.
People of Hispanic origin were on the North American continent centuries before settlers arrived
from Europe in the early 1600s and the thirteen colonies joined together to form the United
States in the late 1700s. The first census of the new nation was conducted in 1790, and counted about four million people, most of whom were white. Of the white citizens, more than 80%
traced their ancestry back to England. There were close to 700,000 slaves and about 60,000 "free Negroes". Only a few Native American Indians who paid taxes were included in the census count, but the total Native American population was probably about one million. By 1815, the population of the United States was 8.4 million. Over the next 100 years, the
country took in about 35 million immigrants, with the greatest numbers coming in the late 1800s and early 1900s. In 1882, 40,000 Chinese arrived, and between 1900 and 1907, there were more
than 30,000 Japanese immigrants. But by far, the largest numbers of the new immigrants were
from central, eastern, and southern Europe. An enormous amount of racial and ethnic assimilation has taken place in the United States. In 1908, play-write Israel Zangwill first used the term "melting pot" to describe the concept of a place where many races melted in a crucible and re-formed to populate a new land. Some years during the first two decades of the 20th century, there were as many as one million new
immigrants per year, an astonishing 1 percent of the total population of the United States.
In 1921, however, the country began to limit immigration, and the Immigration Act of 1924
virtually closed the door. The total number of immigrants admitted per year dropped from as many as a million to only 150,000. A quota system was established that specified the number of
immigrants that could come from each country. It heavily favored immigrants from northern and western Europe and severely limited everyone else. This system remained in effect until 1965, although after World War II, several exceptions were made to the quota system to allow in
groups of refugees.
Why did the author write the passage?
Rationale:
The correct answer is D because the passage provides a comprehensive overview of the history of immigration in the United States. It covers various aspects such as the origins of different ethnic groups, the influx of immigrants from Europe and Asia, the term 'melting pot,' and the evolution of immigration policies over time. The passage summarizes key features of immigration, including population numbers, demographic groups, major immigrant waves, and changes in immigration laws. Therefore, the main purpose of the passage is to summarize the main features of immigration in the United States.

In line 5, the word 'ancestry' is closest in meaning to
Rationale:
The word 'ancestry' refers to a person's family or ethnic background, which aligns most closely with the term 'origins'. Ancestry typically denotes the lineage or heritage of individuals, emphasizing where they come from or their roots. 'Inheritance' refers more to the passing down of property or traits, 'color' is unrelated to the context of ancestry, and 'freedom' does not capture the meaning of 'ancestry'. Therefore, 'origins' is the most appropriate term to convey the concept in this context.

According to the passage, which of the following statements is true?
Rationale:
The correct answer is B. The passage mentions that over the next 100 years after 1815, the United States took in about 35 million immigrants, with the highest numbers arriving in the late 1800s and early 1900s. This period is described as a peak period of immigration in the passage. Choices A, C, and D are incorrect based on the information provided in the passage. A quota system was established in 1924, not 1908. Slaves were counted in the first census, and not only those who paid taxes were included in the count.

What is the closest meaning of the word 'concept' in line 16?
Rationale:
In this context, the word 'concept' refers to an idea or a notion, which aligns closely with the meaning of 'thought'. The term 'location' (choice A) refers to a place, 'type' (choice B) refers to a category or classification, and 'complexity' (choice C) refers to the state of being intricate or complicated, none of which match the context of the word 'concept' in the given line.

States in the late 1700s. The first census of the new nation was conducted in 1790, and counted about four million people, most of whom were white. Of the white citizens, more than 80%
traced their ancestry back to England. There were close to 700,000 slaves and about 60,000 "free Negroes". Only a few Native American Indians who paid taxes were included in the census count, but the total Native American population was probably about one million. By 1815, the population of the United States was 8.4 million. Over the next 100 years, the
country took in about 35 million immigrants, with the greatest numbers coming in the late 1800s and early 1900s. In 1882, 40,000 Chinese arrived, and between 1900 and 1907, there were more
than 30,000 Japanese immigrants. But by far, the largest numbers of the new immigrants were
from central, eastern, and southern Europe. An enormous amount of racial and ethnic assimilation has taken place in the United States. In 1908, play-write Israel Zangwill first used the term "melting pot" to describe the concept of a place where many races melted in a crucible and re-formed to populate a new land. Some years during the first two decades of the 20th century, there were as many as one million new
immigrants per year, an astonishing 1 percent of the total population of the United States.
In 1921, however, the country began to limit immigration, and the Immigration Act of 1924
virtually closed the door. The total number of immigrants admitted per year dropped from as many as a million to only 150,000. A quota system was established that specified the number of
immigrants that could come from each country. It heavily favored immigrants from northern and western Europe and severely limited everyone else. This system remained in effect until 1965, although after World War II, several exceptions were made to the quota system to allow in
groups of refugees.
Which of the following can be inferred from the passage?
Rationale:
The correct answer is A. The passage discusses the implementation of the quota system in 1924 which heavily favored immigrants from northern and western Europe. This preference for specific regions suggests that preserving a developing 'American' culture, which was predominantly influenced by these regions, was a major factor leading to the introduction of the quota system. The passage does not indicate that racial and ethnic assimilation did not occur as planned, nor does it directly mention an increase in tensions if the quota system had not been introduced. Additionally, the quota system was not introduced to limit population growth but rather to control and regulate the influx of immigrants from different regions.
Considered the most influential architect of his time, Frank Lloyd Wright (1867-1959) was born in the small rural community of Richland Center, Wisconsin. He entered the University of
Wisconsin at the age of 15 as a special student, studying engineering because the school had no course in architecture. At the age of 20 he then went to work as a draughtsman in Chicago in order to learn the traditional, classical language of architecture. After marrying into a wealthy
business family at the age of 21, Wright set up house in an exclusive neighborhood in Chicago, and after a few years of working for a few architectural firms, set up his own architectural office. For twenty years he brought up a family of six children upstairs and ran a thriving architectural
practice of twelve or so draughts men downstairs. Here, in an idyllic American suburb, with
giant oaks, sprawling lawns, and no fences, Wright built some sixty rambling homes by the year 1900. He became the leader of a style known as the "Prairie" school - houses with low-pitched roofs and extended lines that blended into the landscape and typified his style of "organic
architecture".
By the age of forty-one, in 1908, Wright had achieved extraordinary social and professional success. He gave countless lectures at major universities and started his Taliesin Fellowship - a visionary social workshop. In 1938 he appeared on the cover of Time magazine, and later, on a
two-cent stamp. The most spectacular buildings of his mature period were based on forms borrowed from nature, and the intentions were clearly romantic, poetic, and intensely personal. Examples of these buildings are Tokyo's Imperial Hotel (1915-22: demolished 1968), and New
York City's Guggenheim Museum (completed 1959). He continued working until his death in 1959, at the age of 92, although in his later years, he spent as much time giving interviews and
being a celebrity, as he did in designing buildings. Wright can be considered an essentially
idiosyncratic architect whose influence was immense but whose pupils were few.
What is the main focus of the passage?
Rationale:
The passage primarily focuses on the life and achievements of the famous architect Frank Lloyd Wright. It provides a detailed account of Wright's early life, education, architectural influences, personal life, professional success, and notable projects. The passage highlights key events in Wright's life, from his education and early work experiences to his architectural style, social impact, and recognition in the architectural world. While elements of modern architecture, the 'Prairie' School, and 'organic architecture' are mentioned, they serve as supporting details to illuminate various aspects of Wright's life and career. Therefore, the correct answer is 'C: the life and achievements of a famous architect.'
Food
Food and drink are necessary and desirable, but their
abuse can cause serious physical and metal problem.
Many physicians believe that overeating is one of the
country's main health problems, since it places a great
strain on the heart, can lead to diabetes, and often shortens
the individual's life span. To fill an emotional void. People
often turn to food when they are bored or lonely.
Another area of concern is alcohol consumption. The
results of alcohol abuse are widely publicized. The social
drinker who becomes alcoholic, the drunken driver's
contribution to highway death, spousal and child abuse,
are all concomitant problems associated with alcohol
abuse.
The information presented in this article is?
Rationale:
The correct answer is D: Unbiased in its approach. The article discusses the necessity and desirability of food and drink but also highlights the potential harms and issues associated with their abuse. It addresses concerns related to overeating, alcohol consumption, and the consequences of alcohol abuse. The article presents a balanced view by acknowledging the benefits of food and drink while also highlighting the negative impacts of their abuse, making it unbiased in its approach.
Not only the students but also the professor ___ stunned by the test results.
Rationale:
In this sentence, 'students' and 'professor' are part of a compound subject joined by 'not only...but also,' which makes the subject singular. Since the subjects are singular, the correct verb to use is 'was,' making choice A the correct answer.
About 6% of the earth is covered by rainforests. The largest rainforest in the world is the
Amazon Basin, which stretches over 2.3 million square miles in nine different South American countries. This area is double the length of all the other remaining rainforests in the world. Brazil contains 60%of the Amazonian rainforest, since it lies at the mouth of the river Amazon. This river is the second largest in the world and contains more than one-fifth oftheworldĆ¢Ä‚¬Ä„¢sfresh water. The Amazon rainforest is a type of wet broadleaf forest. The weather there is very humid and warm as it rains quite a bit. Because of the high rainfall, the forest is very rich and green. The
tree leaves are pointed and narrow so that the raindrops can easily drop off wet plants. This
tropical rainforest has more living species than the entire European continent. There are over 400 types of insects living in one single rain forest tree for a total of 2.5 million species. One square kilometer of rainforest may contain over 75,000 types of trees and approximately 438,000
different kinds of plants, which comes to a total of 90,000 tons of greenery overall. The Amazon rainforest is home to 2,000 birds and mammals, with one in every five birds in the world living there. Local farmers have lived off this rich and diverse land for thousands of years. They have been able to find food and water here without destroying the land. The Kayapo people of Brazil
farm in an environmentally-friendly way. Instead of chemicals, they use burned wood to enrich the soil, and plant banana trees, which attract wasps. These wasps then feed on leafcutter ants and get rid of these harmful insects. The rainforest also offers a lot of tropical fruits, such as bananas and coconuts, as food.
Cinnamon is made from the bark of a rainforest tree. Amazonian Indians use the fruit and stem
of the Buruti plant as a drink, to make bread and to build houses. Many other plants are used as medicine. But the Amazon rainforest is in very big danger of disappearing. 9,169 square miles of
forest have been cut down in 2003 in Brazil alone. An area of the size of a football field is burned down basically every minute, which means that the rain forest may be gone by the year 2030.The dangers related to this type of activity are obvious. Trees take in poisonous carbon
dioxide from the air and give off oxygen. There is more oxygen and less carbon dioxide around a
rainforest. When trees are cut down, however, the amount of carbon dioxide increases, and the
air gets warmer. This leads to global warming, which is extremely harmful to the environment. It
is estimated that the burning of Brazilian rainforests alone produces 200 million metric tons of carbon dioxide ayear. Another danger connected with destroying the rainforest is the disappearance of plants and animals. When trees are cut down, plants and animals have no more
food left and slowly die out. Killing wild animals is illegal in Brazil, but there is plenty of stealing going on. 38 million animals are stolen and sold illegally each year. The most hunted
animals are birds, especially parrots, followed by snakes and the jaguar.
According to the paragraph, which of the following is NOT mentioned about the Amazon Rainforest?
Rationale:
The paragraph details various aspects of the Amazon Rainforest, including its vast size, the presence of the river Amazon, and its climate conditions. However, it does not mention specific precipitation levels. The text discusses the high rainfall in the rainforest but does not provide specific details on precipitation levels. Therefore, the correct answer is C: 'Its precipitation levels' as it is not directly addressed in the paragraph.

What does the author refer to when he says 'rich and diverse land' at the beginning of paragraph 3?
Rationale:
When the author mentions 'rich and diverse land' at the beginning of paragraph 3, they are referring to the incredible biodiversity of the Amazon rainforest, specifically highlighting the presence of 2,000 birds and mammals. This biodiversity includes a wide range of species that contribute to the richness and diversity of the ecosystem, making the Amazon rainforest a unique and vital habitat for numerous animals and plants. The reference to 2,000 birds and mammals emphasizes the vast array of wildlife that thrives in this environment, showcasing the richness and diversity of life forms present in the Amazon rainforest.

Which rainforest plant has more than one use?
Rationale:
The Buriti plant from the Amazon rainforest is a versatile plant with multiple uses. Amazonian Indians use its fruit and stem as a drink, to make bread, and to build houses. Additionally, many other plants in the rainforest are utilized for medicinal purposes. This makes the Buriti plant stand out as a rainforest plant with more than one use.
