Cover the key. Write the first action. Then open the rationale and name why the other choices fail.

Question 1

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 origin of the Moon is that it was formed of the debris from 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 upon the tides than does 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. It is an average distance from Earth of 384,403 km.The Moon has no atmosphere; without an atmosphere, the Moon has nothing to protect it from meteorite impacts, and thus the surface of the Moon is 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 the Earth's. Therefore, a man weighing 82 kilograms on Earth would only weigh 14 kilograms on the Moon.

Why does the author mention 'impact craters' in line 16?

  1. A. To explain the corrosive effects of atmospheric weathering
  2. B. To explain why the Moon has no plant life because of meteorites
  3. C. To show the result of the Moon not having an atmosphere
  4. D. To show the result of the Moon not having active tectonic or volcanic activity
Show answer and rationale

Correct answer: C — To show the result of the Moon not having an atmosphere

The mention of impact craters in the text is to highlight the consequence of the Moon lacking an atmosphere. The absence of an atmosphere on the Moon leaves it vulnerable to meteorite impacts, resulting in the multitude of impact craters on its surface. Choice A is incorrect because the mention of impact craters is not related to atmospheric weathering but rather to the lack of an atmosphere. Choice B is incorrect as it misinterprets the reason for the absence of plant life on the Moon. Choice D is incorrect as the text explicitly states that the Moon lacks tectonic or volcanic activity, which is not the focus of the mention of impact craters.

Question 2

SLEEP: Developing muscle growth is an effective way to stay healthy as we get older, but many people find it difficult to develop this muscle growth, even after modifying their exercise routine and food intake. What many people may not realize is that getting the proper amount of uninterrupted sleep plays a major role in the development of muscle. The hard work of developing muscle is done in the gym, on a track, or on the court, but the actual growth takes place during the rest periods that follow a workout. Your body immediately begins rebuilding the muscle fibers that were broken down during the course of your workout. Much of this process is carried out while you are sleeping, so without a full night of sleep, muscle fibers will not have the opportunity to rebuild. Human growth hormone (HGH) is an amino acid that is central to regulating metabolism, building muscle, facilitating calcium retention, and stimulating the immune system. The amount of HGH in your body spikes significantly during deep sleep, which makes getting at least 7 to 10 hours of sleep every night imperative to anyone hoping to develop additional muscle growth. Recent studies have linked inadequate amounts of sleep to lowered levels of leptin, a hormone in the brain that controls appetite. Test subjects who received less sleep, or frequently interrupted sleep, would crave carbohydrates even after their caloric needs reached satiety. This can contribute to obesity and negatively affect any good habits people may have developed with regard to food intake.

In this passage, which of the following is not mentioned as a role of HGH in the human body?

  1. A. Regulating the metabolism.
  2. B. Stimulating the immune system.
  3. C. Regulating leptin, an appetite-controlling hormone.
  4. D. Facilitating calcium retention.
Show answer and rationale

Correct answer: C — Regulating leptin, an appetite-controlling hormone.

The correct answer is C: Regulating leptin, an appetite-controlling hormone. In the provided passage, it is stated that human growth hormone (HGH) is essential for regulating metabolism, building muscle, facilitating calcium retention, and stimulating the immune system. However, leptin is not mentioned as directly regulated by HGH. Instead, the passage discusses how inadequate sleep can lead to lowered levels of leptin, affecting appetite control. Choices A, B, and D are all roles of HGH explicitly mentioned in the passage, making them incorrect answers. Therefore, C is the correct choice as it was not directly linked to HGH in the passage.

Question 3

Linking San Francisco to Marin County in California, the Golden Gate Bridge is one of the most famous bridges in the world. The bridge crosses over a narrow strait which connects the Pacific Ocean to San Francisco Bay. Prior to the bridge, people traveled by ferry boat across the strait. Although most people thought a bridge was necessary to expedite travel, some residents of the Bay area felt the risk of building the bridge was too great. Joseph Strauss believed that nothing was impossible, and dreams would never come to fruition if risks weren't taken. So, he decided to gather the best and brightest builders, architects, and workers to embark on the challenge of building a bridge across the Golden Gate Strait. With safety nets in place, the construction began in 1937. Building the anchorages first, the builders then moved on to the towers on each end, and then to the three-foot-thick cables to support the suspension bridge. Lastly, workers labored to complete the roadway which became the most dangerous and treacherous part of the entire task. The builders had to keep the bridge balanced, so it wouldn't fall into the bay. Today, over sixty-five years later, the bridge remains a lifeline for the people of the San Francisco Bay Area

Why did Strauss set up a net during the construction of the Golden Gate Bridge?

  1. A. For suspension
  2. B. For balance
  3. C. For aesthetics
  4. D. For safety
Show answer and rationale

Correct answer: D — For safety

Strauss set up a net to ensure the safety of the workers in case of falls during the construction of the Golden Gate Bridge. Safety nets were essential to protect the workers from potential accidents or falls while working on the bridge. Choice A ('For suspension') is incorrect as safety nets were not used for suspension purposes but rather for worker safety. Choice B ('For balance') is incorrect as the balance of the bridge was maintained by other construction elements, not safety nets. Choice C ('For aesthetics') is incorrect as safety nets are not related to the visual appearance of the bridge but rather to the protection of the workers.

Question 4

A nanometer is a billionth of a meter. A DNA molecule is 2 nanometers in diameter. Protein molecules are about 10 nanometers in diameter. A human hair is 100,000 nanometers in diameter. But what is a nanometer and how does it relate to technology? Nanotechnology is defined as the understanding and control of matter at dimensions of roughly 1 to 100 nanometers, a scale at which unique properties of materials emerge that can be used to develop novel technologies and products. At the nanoscale, the physical, chemical, and biological properties of materials differ from the properties of matter either at smaller scales, such as atoms, or at larger scales that we use in everyday life such as millimeters or inches. Nanotechnology involves imaging, measuring, modeling, and manipulating matter only a few nanometers in size. Gold nanoparticles are made of the same material as in jewelry. But when light interacts with particles of gold, different colors are reflected. The different colors can be used in simple medical tests to indicate infection or disease. Metals such as copper become extremely rigid at the nanoscale, rather than bendable as in copper wires seen in everyday use.

What is the major difference between matter at the nanoscale and matter at larger scales such as millimeters or inches?

  1. A. At the nanoscale, metals are rigid, and at larger scales, they are bendable.
  2. B. Matter has different and special characteristics at the nanoscale.
  3. C. At the nanoscale, matter has different properties than matter at the atomic level.
  4. D. There is no difference.
Show answer and rationale

Correct answer: B — Matter has different and special characteristics at the nanoscale.

The correct answer is B. Matter at the nanoscale exhibits unique and special characteristics that distinguish it from matter at larger scales. This can include properties like increased surface area, different melting points, altered conductivity, and enhanced reactivity. Choice A is incorrect as metals at the nanoscale can be more rigid compared to their larger scale counterparts. Choice C is incorrect because matter at the nanoscale has properties that are distinct from both atomic and larger scales. Choice D is incorrect as there are significant differences in how matter behaves and interacts at the nanoscale compared to larger scales.

Question 5

Modern PE Classes: In some schools around the country, physical education classes look a lot different than they did a generation or two ago. Kids are still in motion, stretching, running, lifting, and sweating. But instead of everyone doing the same activity at the same time as a team, they are exercising independently. They are being taught movements and activities that their teachers hope they will incorporate into their lives rather than just perform long enough to get a good grade. By teaching kids the pleasure of exercise, gym teachers hope to instill important lessons about maintaining good health, staying fit, and keeping weight under control. Students can also participate in low-impact sports like yoga, martial arts, and weight lifting. Instead of playing basketball or baseball, they can focus on more general skills like passing the ball. A growing number of physical education (PE) teachers are also putting more of an emphasis on general nutrition and health. With the continual increase in the number of children who are obese, there is greater pressure to teach students how to stay fit. To do this, gym teachers have to look at new ways to introduce exercise to their students that will not intimidate or overwhelm them but instead intrigue and engage them. One other difference found in some modern gym classes is the grading system. Instead of being graded on their ability to run laps in a set time or make a certain number of baskets, the students are graded simply on the effort they make in the class. Some even get extra credit if they are the sweatiest students in the room!

Which is not listed as an example of a low-impact sport?

  1. A. Martial arts
  2. B. Basketball
  3. C. Yoga
  4. D. Weight lifting
Show answer and rationale

Correct answer: B — Basketball

Basketball is not listed as a low-impact sport in the extract provided; the others (martial arts, yoga, and weight lifting) are considered low-impact activities. The extract mentions that students can participate in low-impact sports like yoga, martial arts, and weight lifting in modern PE classes, emphasizing their benefits and the focus on general skills. Basketball, on the other hand, is not included in the list of low-impact sports mentioned in the extract, making it the correct answer. This demonstrates the importance of understanding the difference between high-impact and low-impact sports for maintaining fitness and health.

Question 6

EATING: Consumption of food is a universal necessity. Different cultures have developed different methods to accomplish the task. It is interesting to discover these differences and learn new ways to do things. European cultures developed cutlery (knives, forks, and spoons) to enable people to efficiently eat their food. Correct use of this tools changes with the times- what was polite in 1800 may not be considered proper manners today. China developed the chopstick as an efficient tool for eating. Mastery of the use of chopsticks can be difficult for the person not raised in the culture. The attempts of a novice to use chopsticks can be very amusing to the watcher, but frustrating for the hungry diner. Space travel has created new challenges for consuming food. Squeeze bottles and other unique packaging have enabled space travelers to get their needed nutrition. Chopsticks and forks do not work well in space.

What conclusion can be drawn from the article on Eating?

  1. A. The author thinks chopsticks are funny.
  2. B. Space flight is fun and exciting.
  3. C. The author enjoys trying new food.
  4. D. Diversity is interesting to learn about.

Question 7

The ability to see at a distance, in good light, does not diminish as a result of aging to the extent that other visual acuities do. Myopia, or nearsightedness, is more common to younger eyes, while presbyopia, or farsightedness, more commonly afflicts people as they age. The word presbyopia comes from Greek presbys, "old man," and opia, "eye," and names a condition in which, because the lens of the eye hardens slightly and loses elasticity as a person ages, one cannot as easily focus sharply on nearby objects. This condition leads to the familiar habit of lifting up one's glasses and bringing an object or reading material close to the face so that the eyes can more easily focus on it. The function of the lens is to accommodate different focal points so that sensory data can be correctly directed to the retina for interpretation into images by the brain. Corrective lenses, particularly bifocals or progressive lenses, adjust for the focal point aberration. In essence, they do the work that the eye can no longer do for itself

In the context of the passage, 'accommodate' means to

  1. A. Arrange lodging for
  2. B. Contain
  3. C. Make allowances for
  4. D. Excuse

Question 8

DAY LIGHT SAVINGS TIME: It is a well-known fact that it takes the Earth approximately 365 days to move around the sun. At the same time, the Earth revolves or spins around itself over the course of 24 hours, which explains why there is day and night. One half of the Earth is always facing the Sun and the other half is facing away from it. As a result, there are different time zones dividing the globe. Moving suddenly from one time zone into the other, as when flying for example from Asia to North America, causes jetlag. People feel tired, they wake up suddenly during the night and cannot go back to sleep. It takes time to get used to a new time zone. Another thing to consider is the slight tilting of the Earth towards the sun. The Earth does not stand straight but leans a little to one side. Therefore, when it revolves around the Sun, the middle part of the Earth is always closer to the Sun and gets more heat. This part is called the equator, and above it lathes tropics. Countries at the tropics get the same amount of daylight all the time. The sun always rises at 6 am and sets at 6 pm. In contrast, the tips of the Earth or the Poles get hardly any light at all because they are so far away from the sun. There are two main seasons at the Poles. There are 6 months of summer, when the sun is always shining, even at night, and there are 6 months of winter, when there is constant darkness. In between the tropics and the Poles lies the temperate zone, where there are 4 seasons. The sun rises and sets at different times throughout the year. In the spring and summer, it gets light earlier; in the fall and winter it gets dark earlier. People who live in temperate zones take advantage of that fact to get more daylight. At the beginning of spring, countries in Europe and North America re-adjust their clocks. They change the time on their clocks and watches 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 measure 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 thought 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. Yet his idea was shelved by the British government, who refused it because they thought it was unnecessary. Daylight Savings Time was first put into practice by the German government in 1916 in order to save energy during the First World War. Shortly after, the United Kingdom followed suit, with the United States doing the same in 1918. The law was very unpopular since people had to wake up earlier and many experienced a feeling like jetlag. But the 1970s energy crisis forced the US to make Daylight Savings Time the law. Studies have shown that the introduction of Daylight Savings Time in the spring saved the US 10,000 barrels of oil per day between 1974-1975. 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 move back to Standard Time on the last Sunday in October. But as of 2007, the time re-adjustment happened even earlier, in March and November.

What does the author suggest about the Earth's tilt in the passage on Daylight Savings Time?

  1. A. The Earth's tilt has no effect on the seasons.
  2. B. The Earth's tilt affects the amount of sunlight different areas receive.
  3. C. The Earth's tilt is constant throughout the year.
  4. D. The Earth's tilt changes dramatically during the seasons.

Question 9

VOICE: What effect does your voice have on others? Does it persuade or irritate, attract or repel? One of the worst qualities is harshness. If you ever get the feeling that people are uncomfortable when you speak, it may be that your harsh tones are jarring their eardrums. your voice will sound unpleasant if it is shrill, grating, hard, piercing, brassy, to loud, or too nasal. Harsh voice qualities usually come from too much tension in the throat and jaw. Tension tightens muscles and blocks the relaxed voice tones essential to a pleasing impression. Because tension occurs in higher pitched voices, women tend to have shriller voices than men, which usually makes them less desirable public speakers, newscasters, or political candidates.

Which statement from the passage on Voice is a fact rather than an opinion?

  1. A. One of the worst voice qualities is harshness.
  2. B. Harsh voice qualities come from tension in the throat.
  3. C. Your voice will sound unpleasant if it is shrill or grating.
  4. D. Because tension occurs in higher-pitched voices, women tend to have shriller voices than men.

Question 10

HCFS: The impact of high fructose corn syrup (HFCS) on health has been a topic of concern in recent years. High fructose corn syrup, a sweetener derived from corn, has been linked to various health issues, including obesity. Unlike refined table sugar, which is a natural product, HFCS is manufactured through a chemical process. Studies have shown that rats tend to prefer HFCS over other sweeteners, raising questions about its effects on human health. The American Medical Association (AMA) has examined the implications of HFCS consumption and its potential role in the obesity epidemic. Despite some benefits in terms of cost and versatility in food products, the association has highlighted potential health risks, including increased caloric intake and potential links to obesity. As research continues, the debate over the safety and health implications of HFCS remains relevant.

Which of the following is not mentioned as a detail in the passage about High Fructose Corn Syrup?

  1. A. HFCS and sugar share a biological structure.
  2. B. HFCS is cheaper to use than sugar.
  3. C. HFCS is now used to sweeten a variety of products.
  4. D. HFCS contains more calories than aspartame.

Question 11

MICROBES IN HUMAN HEALTH: There are 10 times more microbes than human cells in the human body. Scientists have long known that the human body hosts a staggering number of microorganisms. Recent discoveries, however, are shedding light on how pivotal these bacteria are in the development of the human immune system. The body supports a wide array of microorganisms specially adapted to survive in particular regions. Remarkably, there is such variation in these microorganisms that few people share the same strains in the same quantities. The colonization of microbes begins at birth. A newborn infant, emerging from the germ-free environment of the womb, is immediately exposed to germs from its mother's birth canal. These bacteria swiftly begin to breed and colonize the infant's body, which becomes their new host. The most fascinating discovery is not just that the immune system tolerates these millions of harmless organisms, but that it may actually rely on their presence to function properly. For example, laboratory mice unable to produce a specific inflammation-reducing molecule were injected with a particular strain of bacteria. After the bacteria colonized, the mice's immune systems developed the ability to synthesize the molecule. Essentially, the mice needed the bacteria for their immune systems to function correctly. This concept is also being applied to humans through a relatively experimental procedure known as fecal bacteriotherapy. This treatment reintroduces healthy bacteria into a colon that has lost its ability to defend against pathogens. While scientists are only beginning to understand the critical role these microorganisms play in human health, early research has yielded remarkable discoveries.

Question 12

Neurologists and biological psychologists have witnessed a sharp increase in the knowledge and understanding of particular structures of the brain over the past two decades. As technology becomes ever more advanced, scientists are able to isolate the functions of even small regions of the human brain. One noteworthy discovery is the role of the amygdala in human fear and aggression. The amygdala, a small, almond-shaped conglomerate, is just one part of the limbic system. Located at the very center of the brain, the limbic system is the core of our 'emotional brain;' each individual structure in the limbic system is somehow connected to an aspect of human emotion. Scientists have found that electrode stimulation of the amygdala can elicit extreme and aggressive acts. Patients or experimental subjects who experience this utter rage and fearlessness have no rational foundation for their reaction. In other words, this aggression is wholly attributable to electrode stimulation. On the other hand, patients with trauma or damage to this structure exhibit a complete absence of aggression. Researchers find that no amount of poking, prodding, or harassment will evoke even remotely aggressive responses from these subjects

The author suggests that persistent passivity and imperturbability may be a direct result of which of the following?

  1. A. Drug-induced stimulation of the amygdala.
  2. B. A stroke that resulted in severe tissue damage in the limbic system.
  3. C. Encephalitis as a result of head trauma.
  4. D. Activation of a strategically implanted electrode in a patient's amygdala.

Question 13

HYPERTENSION: The term hypertension is used to describe the condition of chronically high blood pressure. People who are obese, experience a lot of stress, smoke tobacco products, have a diet with too much salt in it, or have diabetes are often at a higher risk for hypertension. As well, African Americans are more likely to have hypertension than other population groups. Hypertension often develops over many years. Older people are most often diagnosed with hypertension. One reason for this is that blood vessels lose elasticity and stiffen as a person ages. This creates more resistance to the blood flowing through the body and elevates blood pressure. Symptoms of hypertension can include blurred vision, headaches, a buzzing in the ears, fatigue, an irregular heartbeat, and nosebleeds. Hypertension that goes untreated over a period of time can lead to serious complications such as kidney disease, heart disease, loss of vision, heart attack, brain damage, and even early death. Fortunately, treating hypertension reduces blood pressure and can lower the risk of complications. For many people, losing weight can result in a significant decrease in blood pressure. For others, physicians may prescribe one or more medications to help bring blood pressure down into a safe range. One thing is certain: physicians believe that people over the age of 20 should monitor their blood pressure by having it checked at least once a year. Those with a history of hypertension in the immediate family should have it checked more frequently.

Which of the following statements is an opinion related to Hypertension?

  1. A. Obese people are at risk for hypertension.
  2. B. Losing weight can decrease blood pressure.
  3. C. Older people must pay attention to their blood pressure.
  4. D. Blurred vision or dizziness may be a sign of hypertension.

Question 15

Beep!…Beep!…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 “wave of excitation†spreads through the heart wall and is accompanied by electric changes. The wave takes place in three distinct steps.Initially, the “wave of excitation†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.<p>Finally, the ventricles relax, and any changes in the wave indicate to trained medical staff any abnormalities within the heart.

What is the meaning of the word 'emitting' as it is used in the second paragraph?

  1. A. Repelling
  2. B. Releasing
  3. C. Closing
  4. D. Charging
