[Q]: Article: It was a very foggy day in London. The fog was so thick that it was impossible to see more than a foot or so. Buses, cars and taxis were not able to run and were standing by the side of the road. People were trying to find their way about on foot but were losing their way in the fog. Mr. Smith had a very important meeting at the House of Commons and had to get there but no one could take him. He tried to walk there but found he was quite lost. Suddenly he bumped into a stranger. The stranger asked if he could help him. Mr. Smith said he wanted to get to the Houses of Parliament. The stranger told him he would take him there. Mr. Smith thanked him and they started to walk there. The fog was getting thicker every minute but the stranger had no difficulty in finding the way. He went along one street, turned down another, crossed a square and at last after about half an hour's walk they arrived at the Houses of Parliament. Mr. Smith couldn't understand how the stranger found his way. "It is wonderful," he said. "How do you find the way in the fog?" "It is no trouble at all to me," said the stranger, "I am blind."

[Q]: Article: If you exhibit positive characteristics such as honesty and helpfulness, the chances are that you will be thought as a good-looking person, for a new study has found that the perception of physical attractiveness is influenced by a person's personality. The study, which was led by Gary W.Lewandowski, has found that people who exhibit negative characteristics, such as unfairness and rudeness, appear to be less physically attractive to observers.In the study, the participants viewed photographs of opposite-sex individuals and rated them for attractiveness before and after being provided with information about their personalities. After personality information was received, participants also rated the probability of each individual' s becoming a friend and a dating partner.Information on personality was found to significantly change the probability, showing that cognitive processes modify judgments of attractiveness. "Thinking a person as having a desirable personality makes the person more suitable in general as a close relationship partner of any kind," said Lewandowski. The findings show that a positive personality leads to greater expectation of becoming friends, which leads to greater expectation of becoming romantic partners and, finally, to being viewed as more physically attractive.The findings remained consistent regardless of how "attractive" the individual was formerly thought to be or of the participants' current relationship status. "This research provides a positive outcome by reminding people that personality goes a long way toward determining your attractiveness; it can even change people's impressions of how good-looking you are," said Lewandowski.

[A]: In the study the participants were required to _ .

[Q]: Article: Cloning is suggested as a means of bringing back a relative, usually a child, killed tragically. Some parents can understand that wish, but it must first be recognized that the copy would be a new baby and not the lost child. Here lies the difficulty, for the sad parents are seeking not a new baby but a return of the dead one. Since the original would be fondly remembered as having particular talents and interests, would not the parents expect the copy to be the same? It is possible, however, that the copy would develop quite differently. Is it fair for the new child to be placed in a family with such unnatural expectations? Copying is also suggested as a means by which parents can have the child of their dreams. Couples might choose to have a copy of a film star, baseball player or scientist, depending on their interest. But because personality is only partly the result of genetic inheritance , conflicts would be sure to come up if the cloned child failed to develop the same interests as the original. What if the copy of Einstein shows no interest in science? Or the baseball player turns to acting? Success also depends upon fortune. What if the child does not live up to the hopes and dreams of the parents simply because of bad luck? Every baby should be wanted for itself, as an individual. In making a copy of oneself or some famous person, a parent is carefully specifying the way he or she wishes that child to develop. In recent years, particularly in the United States, much importance has been placed on the right of individuals to reproduce in ways that they wish. So I suggest there is a greater need to consider the interest of the child and to refuse these suggested uses of cloning.
