GETTING A GOOD NIGHT'S SLEEP:
Have you ever found yourself staring at the ceiling at 2:00 a.m.? Have you kicked the blankets off to the floor from burning? Many sufferers of insomnia know these situations all too well. As many as 17% of Americans find the restful break of sleep hard to achieve.
Lack of sleep affects intellectual abilities at work or school by causing a deficit in memory, attention, and concentration, which in turn creates a feeling of irritation or depression. Chronic insomnia can result from a medical illness, a psychiatric condition, or from sleep apnea, a condition where an individual actually stops breathing during sleep.
Sleep hygiene, developing good sleep habits, and non-pharmacological therapies such as herbs and spices are some solutions to insomnia. There is no need to live with insomnia, so contact a physician and get a good night's sleep!

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.

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 about the article?
- A. The author explains differences in eating methods.
- B. Eating habits vary across different cultures.

- D. Chopsticks are more suitable than forks for space travel.
Correct Answer: A
Rationale: The correct answer is A. The passage discusses different eating methods in various cultures, focusing on their differences. The author describes the development of cutlery in European cultures, the use of chopsticks in China, and how space travel has influenced eating tools for astronauts. Choice B is incorrect because the passage emphasizes the differences rather than the similarities in eating habits across cultures. Choice C is partially supported by the passage as it mentions that space travel has created new challenges for consuming food, but it is not the main conclusion of the article. Choice D is not directly supported by the passage as it discusses the challenges of using chopsticks and forks in space rather than stating that chopsticks are superior to forks.

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.
