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 1 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.

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.

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 across nine different South American countries. This area is double the size of all the other remaining rainforests in the world. Brazil contains 60% of the Amazonian rainforest, as it lies at the mouth of the Amazon River. 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 classified as a type of wet broadleaf forest. The weather there is very humid and warm, with substantial rainfall contributing to the forest's rich greenery. The tree leaves are pointed and narrow, allowing raindrops to easily slide off wet plants. This tropical rainforest is home to more living species than the entire European continent, with over 400 types of insects living in a single rainforest tree, totaling around 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, resulting in a total of 90,000 tons of greenery overall. The Amazon rainforest is home to 2,000 species of birds and mammals, with one in every five birds in the world residing there. Local farmers have lived off this rich and diverse land for thousands of years, finding food and water without destroying the environment. The Kayapo people of Brazil farm in an environmentally friendly manner. Instead of using chemicals, they burn wood to enrich the soil and plant banana trees, which attract wasps. These wasps feed on leafcutter ants, helping to control these harmful insects. The rainforest also provides a variety of tropical fruits, such as bananas and coconuts, as food sources. Cinnamon is made from the bark of a rainforest tree, and Amazonian Indians use the fruit and stem of the Buruti plant for drinks, bread, and construction. Many other plants are used for medicinal purposes. However, the Amazon rainforest is in significant danger of disappearing. In 2003 alone, 9,169 square miles of forest were cut down in Brazil. An area the size of a football field is burned every minute, suggesting that the rainforest may be gone by the year 2030. The dangers associated with this activity are clear. Trees absorb poisonous carbon dioxide from the air and release oxygen. Rainforests have more oxygen and less carbon dioxide in their vicinity. When trees are cut down, the amount of carbon dioxide increases, resulting in a warmer atmosphere. 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 each year. Another significant danger associated with the destruction of the rainforest is the disappearance of plants and animals. When trees are cut down, plants and animals lose their food sources and gradually die out. While killing wild animals is illegal in Brazil, poaching remains a problem. An estimated 38 million animals are stolen and sold illegally each year. The most hunted animals are birds, especially parrots, followed by snakes and jaguars
Question 3 of 5
According to the information given, which of the following is NOT mentioned about the Amazon Rainforest?
Correct Answer: C
Rationale: The passage provides details about the Amazon Rainforest, such as its size, location, the river Amazon, and its characteristics as a wet broadleaf forest. However, there is no mention of the specific amount of rainfall in the Amazon Rainforest. The passage focuses on various aspects of the rainforest but does not discuss its precipitation levels. Therefore, the correct answer is C: 'Its rainfall.'

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 5 of 5
Was Daylight Savings Time popular in the beginning?
Correct Answer: D
Rationale: Daylight Savings Time was not popular in the beginning. When it was first introduced, people experienced negative effects such as feeling tired due to having to adjust their sleep schedules. The rationale mentions that the law was very unpopular, people had to wake up earlier, and many experienced a feeling like jetlag. These challenges led to people not liking Daylight Savings Time initially.
