Extract:
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.
Question 2 of 5
What is the meaning of the word 'astute' in the last paragraph?
Correct Answer: B
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.

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.
Question 3 of 5
Which of the following is NOT mentioned in the passage?
Correct Answer: D
Rationale: The passage discusses various aspects related to time zones, Earth's movement, and Daylight Savings Time. The cause of jet lag is mentioned, explaining how sudden changes in time zones can disrupt sleep patterns. The amount of daylight at the tropics is also discussed, noting that countries there receive the same amount of daylight consistently. Additionally, the passage explains the reason for the time readjustment due to Daylight Savings Time. However, the passage does not mention why the British government refused Daylight Savings Time, making option D the correct answer.
Extract:
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.
Question 4 of 5
As used in the last sentence of this paragraph, the term 'concomitant' means?
Correct Answer: A
Rationale: In this context, the term 'concomitant' means 'accompanying'. It refers to problems or issues that occur together with something else. The sentence discusses the problems associated with alcohol abuse, such as the social drinker becoming alcoholic, drunken drivers contributing to highway deaths, and spousal and child abuse. These issues are all connected or 'accompanying' problems of alcohol abuse, making choice A, 'Accompanying', the correct answer.
Extract:
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.
Question 5 of 5
In the provided text, the word 'massive' in line 4 is closest in meaning to
Correct Answer: C
Rationale: The word 'massive' in the context of the text is used to describe the size of the body that collided with the Earth to form the Moon. In this context, 'massive' means extremely large or enormous, which aligns most closely with the choice 'Huge.' The collision was not described as dense, impressive, or unavoidable in relation to its size, making 'Huge' the most appropriate synonym.
