GOLDEN GATE BRIDGE:
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 that 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 that 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, 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.
What was the most dangerous part of building the Golden Gate Bridge?
- A. Balancing the road to prevent collapse.
- B. Constructing the towers due to their height.
- C. Suspending the cables with difficulty.
- D. Ensuring the critical balance of the bridge.
Correct Answer: A
Rationale: The most dangerous part of building the Golden Gate Bridge, as mentioned in the passage, was keeping the road balanced to prevent it from collapsing. While constructing the towers and suspending the cables were challenging tasks, the passage specifically highlights the balancing of the bridge as the most treacherous aspect of the construction. Therefore, choice A is the correct answer. Choices B, C, and D are incorrect as they do not reflect the primary danger emphasized in the passage.

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 is the main idea of the passage on Daylight Savings Time?
- A. Daylight Savings Time helps save energy.
- B. Daylight Savings Time is unnecessary and outdated.
- C. Daylight Savings Time is a law to conserve energy during wars.
- D. Daylight Savings Time was first implemented in Germany.
Correct Answer: A
Rationale: The correct answer is A: "Daylight Savings Time helps save energy." The passage explains how Daylight Savings Time is implemented to take advantage of more daylight, which results in energy savings. By adjusting clocks ahead in spring, people can make use of additional daylight in the evenings, leading to reduced energy consumption. This measure was introduced to address energy crises and has been shown to save significant amounts of energy. Choice B is incorrect as the passage does not portray Daylight Savings Time as unnecessary or outdated; instead, it highlights its benefits. Choice C is partially correct but not the main idea of the passage, as saving energy is the primary focus. Choice D is mentioned in the passage but is not the main idea; the main idea is about the purpose and benefits of Daylight Savings Time.

Why was the roadway of the Golden Gate Bridge so dangerous to build?
- A. It was located above a fast-moving river.
- B. It had to be perfectly balanced to avoid collapse.
- C. The materials used were very unstable.
- D. It was built during bad weather.
Correct Answer: B
Rationale: The correct answer is B. The passage describes how the road had to be balanced during construction to avoid collapse into the bay. Choice A is incorrect as the Golden Gate Bridge crosses a strait, not a river. Choice C is incorrect as there is no mention of unstable materials. Choice D is incorrect as bad weather is not highlighted as a specific reason for the danger in building the roadway.
AMAZON RAINFOREST:
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 a year. 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.
What is the author's primary purpose for writing the passage on the Amazon Rainforest?
- A. To entertain readers with facts about the rainforest.

ELECTORAL COLLEGE:
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. It's all very confusing, but the founding fathers know what they were doing. By having and using the Electoral College candidates' 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.
What is the main reason the author wrote the passage about the Electoral College?
- A. To criticize the complexity of the Electoral College.
- B. To explain how the Electoral College works.
- C. To advocate for abolishing the Electoral College.
- D. To promote the benefits of the Electoral College.
Correct Answer: B
Rationale: The correct answer is B. The passage primarily aims to explain how the Electoral College functions in U.S. elections. It provides details on how the Electoral College operates, including the allocation of electoral votes based on states' representation in Congress, the role of senators and representatives, and how electoral votes are cast during presidential elections. Choices A, C, and D are incorrect because the passage does not criticize, advocate for abolishing, or promote the benefits of the Electoral College. Instead, it focuses on clarifying its mechanism.
BICYCLES:
Today, bicycles are so common that it's hard to believe they haven't always been around. But two hundred years ago, bicycles didn't even exist, and the first bicycle, invented in Germany in 1818, was nothing like our bicycles today. It was made of wood and didn't even have pedals. Since then, however, numerous innovations and improvements in design have made the bicycle one of the most popular means of recreation and transportation around the world.
In 1839,Kirkpatrick Macmillan, a Scottish blacksmith, dramatically improved upon the original bicycle design. Macmillan's machine had tires with iron rims to keep them from getting worn down. He also used foot-operated cranks like pedals,so his bicycle could be ridden at a quick pace. It didn't look much like a modern bicycle, though, because its back wheel was substantially larger than its front wheel.
In 1861, the French Michaux brothers took the evolution of the bicycle a step further by inventing an improved crank mechanism. Ten years later, James Starley, an English inventor, revolutionized bicycle design. He made the front wheel many times larger than the back wheel, put a gear on the pedals to make the bicycle more efficient, and lightened the wheels by using wire spokes. Although this bicycle was much lighter and less tiring to ride, it was still clumsy, extremely top heavy, and ridden mostly for entertainment.
It wasn't until 1874 that the first truly modern bicycle appeared on the scene. (14) Invented by another Englishman, H.J. Lawson, the "safety bicycle" would look familiar to today's cyclists. This bicycle had equal-sized wheels, which made it less prone to toppling over. Lawson also attached a chain to the pedals to drive the rear wheel. With these improvements, the bicycle became extremely popular and useful for transportation. Today they are built, used, and enjoyed all over the world.
What does Macmillan's invention of the bicycle signify?
- A. He made important changes in bicycle design.
- B. He invented the first bicycle with pedals.
- C. He developed the modern chain drive.
- D. He improved the safety of bicycles.
Correct Answer: B
Rationale: Macmillan's invention of pedals was a significant milestone in bicycle history as it allowed for quicker and more efficient travel. The provided extract mentions that Macmillan's bicycle had foot-operated cranks like pedals, which enabled the rider to travel at a quick pace. This innovation marked a crucial development in the evolution of bicycles. While choices A, C, and D are related to advancements in bicycle design and safety, the key significance of Macmillan's invention lies in introducing pedals to bicycles, making choice B the correct answer.
