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.

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.
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.

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.
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 is the best title for the passage on bicycles?
- A. Bicycles Are Better.
- B. Cycle Your Way to Fitness.
- C. A Ride through the History of Bicycles.
- D. The Popularity of Bicycles.
Correct Answer: C
Rationale: The correct answer is C: 'A Ride through the History of Bicycles.' This title best captures the passage's focus on the historical development and evolution of the bicycle from its invention to its modern form. Choice A, 'Bicycles Are Better,' is too general and doesn't encompass the historical aspect discussed in the passage. Choice B, 'Cycle Your Way to Fitness,' focuses solely on the fitness aspect of bicycles, ignoring the broader historical context. Choice D, 'The Popularity of Bicycles,' touches on one aspect but does not encompass the comprehensive historical journey presented 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 does the author suggest about the Earth's tilt in the passage on Daylight Savings Time?
- A. The Earth's tilt has no effect on the seasons.
- B. The Earth's tilt affects the amount of sunlight different areas receive.
- C. The Earth's tilt is constant throughout the year.
- D. The Earth's tilt changes dramatically during the seasons.
Correct Answer: B
Rationale: The author suggests that the Earth's tilt affects the amount of sunlight different areas receive, influencing the seasons. The passage explains how the tilt of the Earth towards the sun results in different regions receiving varying amounts of sunlight, leading to the existence of seasons. This tilt causes regions near the equator to receive more sunlight consistently, while the Poles experience periods of constant darkness or sunlight, creating different seasons. Choices A, C, and D are incorrect because the passage clearly states that the Earth's tilt influences sunlight distribution and subsequently impacts the seasons.
