I'm taking a test and have to guess the right answer to the question after the article. Article: Sharks have lived in the oceans for over 450 million years, long before dinosaurs appeared. There are now about 360 species of sharks, whose size, behavior, and other characteristics differ widely. Every year, we catch and kill over 100 million sharks, mostly for food and for their fins. Dried shark fins are used to make shark fin soup, which sells for as much as $50 a bowl in fine Hong Kong restaurants. Other sharks are killed for sport and out of fear. Sharks are vulnerable to overfishing because it takes most species 10 to 15 years to begin reproducing and they produce only a few offspring . Influenced by movies and popular novels, most people see sharks as people-eating monsters. This is far from the truth. Every year, a few types of shark injure about 100 people worldwide and kill about 25. Most attacks are by great white sharks, which often feed on sea lions and other marine mammals. They sometimes mistake human swimmers for their normal prey, especially if they are wearing black wet suits. If you are a typical ocean-goer, your chances of being killed by an unprovoked attack by a shark are about 1 in 100 million. You are more likely to be killed by a pig than a shark and thousands of times more likely to get killed when you drive a car. Sharks help save human lives. In addition to providing people with food, they are helping us learn how to fight cancer, bacteria, and viruses. Sharks are very healthy and have aging processes similar to ours. Their highly effective immune system allows wounds to heal quickly without becoming infected, and their blood is being studied in connection with AIDS research. Sharks are among the few animals in the world that almost never get cancer and eye cataracts . Understanding why can help us improve human health. Chemicals taken from shark cartilage have killed cancerous tumors in laboratory animals, research that someday could help _ your life. Sharks are needed in the world's ocean ecosystems. Although they don't need us, we need them. We are much more dangerous to... Question: According to the passage, which of the following statements is NOT true? Options: A: There are many different species of sharks, but only a few of them are dangerous to humans. B: Sharks never get ill. C: Sharks are a valuable resource for human. D: Sharks play an important role in the ocean ecosystem.

I'm taking a test and have to guess the right answer to the question after the article. Article: There are many older people in the world and there will be many more. A little-known fact is that over 60 percent of the older people live in developing countries. According to the World Health Organization, by 2020 there will be 1 billion, with over 700 million living in developing countries. It is a surprising fact that the population ageing is particularly rapid in developing countries. For example, it took France 115 years for the proportion of older people to double from 7 percent to 14 percent. It is estimated to take China a mere 27 years to achieve this same increase. What are the implications of these increased numbers of older folk? One of the biggest worries for governments is that the longer people live ,the more likelihood there is for diseases and for disability. Attention is being paid to the need to keep people as healthy as possible, including during old age, to lessen the financial burden on the state. Another significant problem is the need for the younger generations to understand and value the older people in their society. In some African countries, certainly in Asia, older people are respected and regarded as the ones with special knowledge. Yet traditions are fading away daily, which does not ensure the continued high regard of older people. As society changes, attitudes will change. Much needs to be done to get rid of age discrimination in employment. Life-long learning programs need to be provided to enable older people to be active members in a country's development. Social security policies need to be established to provide adequate income protection for older people. Both public and private schemes are vital in order to build a suitable safety net. To achieve equality in such matters will take considerable time and effort. One thing is sure:there is no time to be lost. Question: Which of the following measures is NOT mentioned to solve the population ageing problem? Options: A: Getting rid of age discrimination in employment. B: Ensuring adequate income protection for older people. C: Supplying life-long learning programs to older people. D: Providing free health care for sick older people.

I'm taking a test and have to guess the right answer to the question after the article. Article: It is always hard for a small fish to live in a big pond. Pluto's recent departure from the classical planet family clearly proves that size really matters. Astronomers voted on August 24 to create the first scientific definition of the word planet, and Pluto obviously didn't make the cut. It turned out to be only a "dwarf planet" . After weeks of heated debate, over 2,500 astronomers from 73 countries voted on the definition of a "planet" at a conference of the international Astronomical Union (IAU). According to the definition, a planet must have a clear neighborhood around its orbit. Pluto has widely been considered a planet since its discovery in 1930. Unfortunately, it has a special orbit which overlaps with Neptune's. It is all because, compared with Neptune, Pluto is very small. It is attracted by Neptune's gravity when the two planets get closer. According to IAU, a "dwarf planet" should have an orbit around the Sun. It will not have a clear neighborhood around its orbit, and must not be a satellite. The new classification means that the science textbooks will have to be updated. The solar system is now made up of the eight "classical planets," together with a number of dwarf planets. The classical planets are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. The debate over Pluto's status started in 1992. After an advanced telescope was sent into space, astronomers started find a belt of objects, which lies beyond Neptune. The belt contains nearly 1,000 objects, including Pluto. As they continued the exploration, scientists recently discovered at least 41 dwarf planets at the edges of the solar system. There are at least two objects of a similar size to Pluto. It seems that even if the IAU had kept Pluto's status as a planet, the classical theory of nine planets in the solar system would have had to be changed, but the other way around. More dwarf, planets of a similar size to Pluto would join the family of planets. Scientists will probably find many more dwarf planets. Question: According to the passage, Pluto is _ . Options: A: a planet which has a clear neighborhood around its orbit B: a satellite of Neptune which was discovered in 1930 C: the smallest planet in the solar system D: a planet which has an orbit around the sun

I'm taking a test and have to guess the right answer to the question after the article. Article: "Have you ever heard the old saying, "Never judge a book by its cover"? This is a good rule to follow when you try to judge the cleverness of others by their looks and performance. Some people have minds that shine only in certain situations. A young man with an unusual gift in novel writing may find himself speechless before a pretty girl. But don't make the mistake of thinking he might not be that clever. With a pen and paper, he can tell what he thought very well. Other people may fool you into mistakenly thinking they are clever by putting up a good front. A student who listens carefully and takes notes in class is sure to make a good impression on his teachers. But when it comes to exams, he may get scores much lower than his classmates. We may conclude that:you can't judge someone by appearances. The only way to tell whether a person is clever or not is to get to know him by observing how he reacts to different situations. The more situations you observe, the more accurate your judgement is likely to be. So take your time. Don't judge the book by its cover. Question: According to the passage, true knowledge of a person's cleverness comes from _ . Options: A: the grades he gets in school B: his manners at parties C: his outward appearanc D: how he behaves in different situations
