Ques:Read the following article and select the best answer. Article: Research shows that humans switch from selfish to unselfish behavior when they are watched. Do you? A picture of a set of eyes on a computer screen can cause a change in the way people act. Even images of eyes on a charity donation, collection box encourage people to be unselfish, because people put more money in a collection box that has a picture of eyes on it than they do when a flower symbol is on the box. Manfred Milinski from the Max-Planck Institute for Evolutionary Biology in Germany and Bettina Rockenbach of the University of Berlin, the authors of a new study, found that people act better when they are being watched because they feel they will be rewarded for good behavior. Their report also referred to other research showing that this response of behaving well when watched is somehow _ into humans and people respond this way unconsciously, or without realizing it. It is not just humans that act unselfishly when they are being watched. A fish called the grooming fish cleans other fish. When other fish are around, it is gentler. When no other fish are around, however, the grooming fish bites chunks from the fish it is supposed to be cleaning. The researchers suggest that the best way to get people to behave in the correct way is to make them feel watched. This could be the reason for the success of a famous American army poster. On it was a picture of an elderly man staring fiercely and pointing, it appeared, to the person who was looking at the poster. Under the picture was the caption 'I Want You' It encouraged hundreds of thousands of young American men to join the army during the Second World War to fight the Germans and Japanese. Question: According to the text, which of the following statements is true? - People pretend to behave worse when they are watched. - Fish bite other fish in a fish tank when they are alone. - People donatemore money when they feel they are watched. - Soldiers fought better during World War II because of a poster.

Ans:People donatemore money when they feel they are watched.

Ques:Read the following article and select the best answer. Article: Why does the Leaning Tower of Pisa in Italy lean? It leans because of a mistake. It has leaned almost since the day the tower was built. In 1173, the people of Pisa, Italy, wanted to build a bell tower. They wanted the tower to be the most beautiful bell tower in all of Italy. The city also needed a bell tower because the church did not have one. However, there was a problem. As soon as the first floor of the building was finished, the tower started to lean. Builders tried to make the building straight again as they added more floors, but they couldn't figure out how to make it stop leaning. It took almost 180 years to finish the tower. Since then, the tower has leaned by another millimeter every year. Today, the Leaning Tower has eight floors and is 54.5 meters tall. By 1990, it was leaning by about 4 meters to one side. It was also slowly sinking into the ground. Many people became worried that it would soon fall apart. In 1998, repair works began on the tower, and by the end of 2001, it had been moved back by 45 centimeters. The tower will still lean, however, so it will need to be repaired again---in another 200 years. Question: When was the tower finished? - in 1173 - in 1180 - in 1353 - in 1474

Ans:in 1353

Ques:Read the following article and select the best answer. Article: Professor Reason recently persuaded 35 people to keep a diary of all their absent-minded actions for two weeks. When he came to analyze their embarrassing errors, he was surprised to find that nearly all of them fell into a few groups. One of the women, for instance, on leaving her house for work one morning threw her pet dog her earrings and tried to fix a dog biscuit on her ear. "The explanation for this is that the brain is like a computer," explains the professor. "People programme themselves to do certain activities regularly." It was the woman's custom every morning to throw her dog two biscuits and then put on her earrings. "But somehow the action got reversed in the programme." About one in twenty of the incidents the volunteers reported were these "programme assembly failures." Twenty percent of all errors were "test failures" -- mainly due to not verifying the progress of what the body was doing. A man about to get his car out of the garage passed through the back yard where his garden jacket and boots were kept, put them on -- much to his surprise. A woman reported, "I got into the bath with my socks on." The commonest problem was information "storage failures". People forgot the names of people whose faces they knew, went into a room and forgot why they were there, mislaid something, or smoked a cigarette without realizing it. The research so far suggests that while the central processor of the brain is liberated from second-to-second control of a well-practiced routine, it must repeatedly switch back its attention at important decision points to check that the action goes on as intended. Otherwise the activity may be gotten by another frequently and recently used programme, resulting in embarrassing errors. Question: The purpose of the professor's research is to _ . - show the difference between men and women - sort and explain some errors in human actions - find the causes which lead to computer failures - compare computer functions with brain working

Ans:sort and explain some errors in human actions

Ques:Read the following article and select the best answer. Article: Some snakes eat other snakes, even poisonous ones. The poison does not do them any harm . Snakes can swallow things that are bigger around than they themselves are. This is possible because the jawbones are loosely joined, and the mouth can stretch to make room for a fat animal. The snake's slim body stretches to make space for the animal when it is inside. Many snakes eat birds' eggs or frogs . Others eat pests , mice and other animals that harm crops on farms. Because snakes do this valuable work, you should never kill one. It is too dangerous for you to kill a poisonous one. Leave that job to experts. Question: In writing this passage the writer mainly wants us to _ - have a better impression about snakes - like snakes - kill snakes with the help of experts - regard snakes as one of man's best friends

Ans:
have a better impression about snakes
