Article: Read the following interview with Dr John Bass, an international shark  specialist who has spent many years studying sharks: First of all, doctor, are all sharks dangerous?   No, they aren't. There are about 250 different kinds of sharks, but fewer than 30 of them are dangerous to humans. Certain sharks are very aggressive   and we should fear them, but the danger of shark attacks is much lower than most people think.   So which sharks are dangerous?   The Great White shark is the most dangerous. Then there is the Tiger shark, which other sharks are afraid of, and the Blue shark. Both of them are very fast and dangerous.   Which are the biggest and smallest sharks?   The Whale shark is the biggest shark in the world. It grows up to 15 m in length and weighs as much as six large cars. The smallest shark, which is found near prefix = st1 /Japan, could fit into the palm of your hand because it is only 15-20 cm long.   Do all sharks have teeth ?   Yes, they do. Most sharks have hundreds, sometimes even thousands, of sharp teeth. These are arranged in rows of four or more. They fit quite loosely in the jaw. When the front ones break off or fall out, spare teeth move forwards from the rows behind: Sharks get a new set of teeth every two weeks. In 10 years, a Tiger may lose as many as 24,000 teeth!   That's lots of teeth! What kind of food do sharks eat?   Most sharks feed on small fish, and they keep the oceans healthy by eating sick and injured fish. However, hungry sharks will eat almost anything, including smaller sharks and even rubbish. Inside one Tiger shark which was found, there was a tin can, a bicycle tyre , a leather wallet and an alarm clock!   And how do sharks find their food, doctor?   A shark's sense of smell is excellent. It will follow the smell of blood across thousands of metres of ocean. They also see well, and they have good hearing. Sharks can feel movement in water very easily too, and it is possible for them to feel a fish moving as far as 30 m away. Question: Choose the best title for this passage   _  .

Article: That"Monday morning feeling"could be a crushing pain in the chest which leaves you sweating and gasping for breath. Recent research from Germany and Italy shows that heart attacks are more common on Monday mornings and doctors blame the stress of returning to work after the weekend break. The risk of having a heart attack on any given day should be one in seven, but a six-year study helped by researchers at the Free University of Berlin of more than 2, 600 Germans showed that the average person had a 20 percent higher chance of having a heart attack on a Monday than on any other day. Working Germans are particularly not protected against attack, with a 33 percent higher risk at the beginning of the working week. Non-workers, by comparison, appear to be no more at risk on a Monday than any other day. A study of 11, 000 Italians proved 8 a. m. on a Monday morning as the most stressful time for the heart, and both studies showed that Sunday is the least stressful day, with fewest heart attacks in both countries. The finding could lead to a better understanding of what is the immediate cause of heart attacks, according to Dr Stefan Willich of the Free University. "We know a lot about long-term risk factors such as smoking and cholesterol but we don't know what actually causes heart attacks, so we can't give clear advice on how to prevent them, "he said. Monday mornings have a double helping of stress for the working body as it makes a rapid change from sleep to activity, and from the relaxing weekend to the pressures of work. "When people get up, their blood pressure and heart rate go up and there are hormonal changes in their bodies, "Willich explained. "All these things can have an unfavorable effect in the blood system and increase the risk of a clot which will cause a heart attack." "When people return to work after a weekend off, the pace of their life changes. They have a higher workload, more stress, more anger and more physical activities,"said Willich. Question: It can be learned from this passage that the heart attack has something to do with all the following EXCEPT   _  . Yes or no, is the answer "blood type"?
No

Article: Alfred Alder, a famous psychiatrist, had an interesting experience. When he was a small boy he got off to a poor start in arithmetic. His teacher got the idea that he had no ability in arithmetic, and told his parents what she thought in order that they would not expect too much of him. In this way, they too developed the idea, "Isn't it too bad that Alfred can't do arithmetic?" He accepted their mistaken estimate of his ability, feeling that it was useless to try, and that he was very poor at arithmetic, just as they expected. One day he became very angry at the teacher and the other students because they laughed when he said he saw how to do a problem which none of the other students had been able to solve. Adler succeeded in solving the problem. This gave him confidence. He rejected the idea that he couldn't do arithmetic and was determined to show them that he could. His anger and his new found confidence stimulated him to go at arithmetic problems with a new spirit. He now worked with interest, determination, and purpose, and he soon became extraordinarily good at arithmetic. He not only proved that he could do arithmetic, but he learned early in life from his own experience that, if a person goes at a job with determination and purpose, he may astonish himself as well as others by his ability. This experience made him realize that many people have more ability than they think they have, and that lack of success is as often the result of lack of knowledge of how to apply one's ability, lack of confidence, and lack of determination as it is the result of lack of ability. Question: Alfred gained confidence in learning arithmetic  _  . Yes or no, is the answer "after he managed to find a solution to a difficult problem"?
No

Article: They are among the 250, 000 people under the age of 25 who are out of work in the Netherlands, a group that makes up 40 percent of the nation's unemployed. A storm of anger boils up at the government-sponsored   youth center, even among those who are continuing their studies. "We study for jobs that don't exist," Nicollets Steggerda, 23, said. After thirty years of prosperity, unemployment among 10 member nations of the European Community has reached as much as 11 percent, affecting a total of 12.3 million people, and the number is climbing. The bitter disappointment long expressed by British youths is spreading across the Continent. The title of a rock song "No Future" can now be seen written on the brick walls of closed factories in Belgium and France. One form of protest  tends to put the responsibility for a country's economic troubles on the large numbers of "guest workers" from Third World nations, people welcomed in Western Europe in the years of prosperity. Young Europeans, brought up in an extended period of economic success and general stability, seem to be similar to Americans more than they do their own parents. Material enjoyment has given them a sense of expectation, even the right to a standard of living that they see around them. "And so we pass the days at the discos, or meet people at the cafe, and sit and stare," said Isabella Cault. "There is usually not much conversation. You look for happiness. Sometimes you even find ." Question: Unemployment in the Netherlands has affected    _ Yes or no, is the answer "about 0.6 million people"?
