[Q]: Article: Long after the 1998 World Cup was won, disappointed fans were still cursing the disputed refereeing decisions that denied victory to their team. A researcher was appointed to study the performance of some top referees. The researcher organized an experimental tournament involving four youth teams. Each match lasted an hour, divided into three periods of 20 minutes during which different referees were in charge. Observers noted down the referees' errors, of which there were 61 over the tournament. Converted to a standard match of 90 minutes, each referee made almost 23 mistakes, a remarkably high number. The researcher then studied the videotapes to analyse the matches in detail. Surprisingly, he found that errors were more likely when the referees were close to the incident. When the officials got it right, they were, on average, 17 meters away from the action. The average distance in the case of errors was 12 meters. The research shows the optimum distance is about 20 meters. There also seemed to be an optimum speed. Correct decisions came when the referees were moving at a speed of about 2 meters per second. The average speed for errors was 4 meters per second. If FIFA, football's international ruling body, wants to improve the standard of refereeing at the next World Cup, it should encourage referees to keep their eyes on the action from a distance, rather than rushing to keep up with the ball, the researcher argues. He also says that FIFA's insistence that referees should retire at age 45 may be misguided. If keeping up with the action is not so important, their physical condition is less critical.
Answer: analyse the causes of errors made by football referees
[A]: The experiment conducted by the researcher was meant to _ .

[Q]: Article: Most Americans think the quality of life for adults under 30 years old, or Generation Y, won't be as good as it is for their baby-boomer parents, according to a new poll. More than 60 percent of people are pessimistic about the future, and 71 percent of young Americans under 30 said they would rather go back in time than leap to the future. "It's interesting how strongly people feel things are getting worse, and how strongly people are backward looking," said Michael Hogan, 35, executive online editor at Vanity Fair which conducted the survey with CBS News. "This is a time of high unemployment, people coming out of school with very few job prospects. The past probably seems more comforting," he added. Although the past may seem appealing for young Americans, only 50 percent of seniors over 65 said they wanted to travel back in time. The nationwide poll of 1,167 adults, which included questions about culture, lifestyle and politics, also revealed that if given the choice to take anything with them to the afterlife, 25 percent would take a pet, 47 percent would opt for a photo album but only nine percent wanted to take an iPhone or a Blackberry. Despite romancing the past, people believe in rewarding the forward-minded. Thirty-three percent of those polled believe Internet entrepreneurs are most deserving of their large salaries, followed by 15 percent for sports stars and 12 percent for bankers. Only eight percent felt movie stars should get the dollars they do. And despite a recent trip to the United States, more than three-quarters of people questioned could not identity David Cameron as the prime minister of Great Britain. Twenty seven percent might have confused him with "Avatar" director James Cameron when they thought he was a movie director.
Answer: David Cameron isn't as popular in America as James Cameron
[A]: From this passage we learn that _

[Q]: Article: Richard Branson, an English business magnate, has had great, global success. He is best known as the founder of Virgin Group, which consists of more than 400 companies. So what, I asked, is his most important secret to success? His answer was simple: look for the best in other people. Throughout his life he's never thought ill of other people. He looks for the best and praises them. Branson at times seems almost not human. He's too good at what he does. No, great. Nearly perfect. When he starts something, he is very likely to succeed. He has fallen out with others though, like anyone else. He is human. He told me:"Life is short and the world is much smaller than one realizes. You are going to come across people time and time again in the most surprising places ... As a leader it's even more important to be out there praising and encouraging people. If you do fall out with somebody in life, even if you think it was their mistake, give them a call. Befriend them. Go out to lunch with them." The greatest leaders in the world have taught forgiveness. Perhaps the most extreme example is Nelson Mandela who invited his former prison guard to his inauguration and even had lunch with a man who in the past wanted him to be sentenced to death. Life is too short. We are humans and sometimes we make mistakes and anger people. What defines us is not those who are able to avoid confrontation , but those who are able to deal with it. The human body is able to self-heal when we are cut. In that same manner, we must heal our past relationships. Branson wins respect from those around him. A natural-born leader, he is always deep in thought and hungry for more; always one step ahead. And it was Richard Branson who taught me about forgiveness.
Answer: generosity
[A]:
Richard Branson's success lies in his _ .
