问题     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.
The experiment conducted by the researcher was meant to ______.

选项 A、review the decisions of referees at the 1998 World Cup
B、analyse the causes of errors made by football referees
C、set a standard of football refereeing
D、reexamine the rules for football refereeing

答案A

解析 根据文章第一段,尤其是第二句“A researcher was appointed to study the performance of some top referees",可知这次实验的目的是运用对本次模拟赛的发现来分析1998年世界杯赛中裁判的判罚是否有误,所以A 是正确答案。在四个选项中B 是干扰度最高的,但是它是实验本身,也是作者以这次实验为例要说明的问题,而不是组织实验的目的。
