Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: Sharks are among the oldest animals on Earth. There are hundreds of kinds of sharks. Most are about two meters long. The dogfish shark, however, is less than twenty centimeters in length. A shark has an extremely good sense of smell. It can find small amounts of matters in water, such as blood, body liquids and chemicals produced by animals. These powerful senses help sharks find their food. Sharks eat fish, other sharks, and plants that live in the ocean. Sharks grow slowly. About forty percent of all sharks lay eggs. The others give birth to live young. Some sharks carry their young inside their bodies as humans do. Some sharks are not able to reproduce until they are twenty years old. Most reproduce only every two years. And they give birth to fewer than ten young sharks. For this reason, over-fishing of sharks is of special danger to the future of the animal. Sharks are important for the world's oceans. They eat injured and diseased fish. Their hunting activities mean that the numbers of other fish in ocean waters do not become too large. This protects the plants and other forms of life that exist in the oceans. People hunt sharks for sport, food, medicine and their skin. Experts say the international market for some kinds of sharks has increased because many parts of a shark are valuable.Collectors pay thousands of dollars for the jaws of a shark. Shark liver oil is a popular source of Vitamin A. The skin of a shark can be used like leather. In Asia, people enjoy a kind of soup made from shark fins. Experts say a fisherman can earn a lot of money for even one kilogram of shark fins. Sharks are among the oldest animals on Earth, but some sharks are in danger of disappearing from Earth. If too many sharks in one area are killed, that group of sharks may never return to normal population levels. Question: Sharks eat other fish, _ . Options: A: which is a threat to all other forms of life in the oceans B: which is a protection for plants and other forms of life in the oceans C: which helps prevent diseases from spreading D: which helps the number of other fish to grow
Ans: B

Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: After years of study, I have known there are only two types of people in this world:those who get to the airport early and those who arrive as the plane is about to take off. If there were any justice in this world, the early-airport people would be rewarded for doing the right thing and the late-airport people would be punished. But the early-airport people get ulcers , heart attacks and bite their fingernails to the bone. The late-airport people are hardly aware that they are flying. A guy of that kind once said, "Don't hurry. If you miss your flight, it's because God didn't want you to go."This is clearly a guy who is never going to get an ulcer. Early-airport people suffer another"name". They are called exactly what they are--wimps . I know. I am an early-airport person for years. My luggage will get on the plane first, which makes it the last luggage they take off the plane after landing. Another strange thing:No matter how early I showed up, I was always told that someone had called two or three years ahead of me and asked for the best seat. I figured it was a trick. I figured there was someone in America who called every airline every day and said, "Is that wimp Simon flying somewhere today? If he is, give me his seat. " After a lifetime arguing with my wife over whether I really have to pack 24 hours in advance and set the alarm clock four hours ahead, I have learned another fact about early-airport people and late-airport people: They always marry each other. Question: The purpose of writing the passage is to _ . Options: A: give useful tips on taking a plane B: offer advice about catching a plane C: express the writer's anxiety about taking planes D: show people's two attitudes towards catching planes
Ans: D

Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: Every year, more than four million babies are born in the United States. Some parents named their children based on family, cultural or religious traditions. Girls are often named after a family member but rarely their mothers. Sons, though, are often named after their fathers. Every year the Social Security Administration releases a list of the most popular baby names in America. Last year, Jacob was the most popular boy name and Emma the number one name for girls. These days, the choice of a baby name seems to be guided as much by individual desires as by tradition. This is shown in the fact that the most popular baby names are not as popular as they used to be. Researchers at San Diego State University in California did a study. They found that thirty-two percent of boys received one of the ten most popular names in 1955. The same was true for twenty-two percent of girls. By 2007, however, the numbers were down to less than ten percent of boys and only eight percent of girls. "People are more and more interested in finding unusual names. And now since we have the information on the Internet of what the most popular names are, the percentage of kids who get them actually is going down because people are able to avoid them much more successfully than they did before," said Cleveland Evans, a professor of psychology at Bellevue University. Parents can find plenty of advice on the Web and in bookstores about choosing a baby name. A lot has also been written about the possible effects that a name might have on a child's future. There are studies that suggest children with unusual names are more likely to be teased. Other studies suggest that as adults, they might be less likely to get called for a job interview. Yet other research suggests that giving a child an unusual name might help build character. What all this adds up to is a big responsibility for parents to consider what's really in a name. Question: Parents name their sons according to the following EXCEPT _ . Options: A: family tradition B: cultural customs C: a most popular baby name D: their fathers' names
Ans:
C
