问题   Long after the 2010 World Cup was won,disappointed fans were still questioning the refereeing on their decisions that denied victory to their teams.A researcher was asked 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 6 1 over the tournament.Convened to a standard match of 90 minutes,each referee made almost 23 mistakes a very high number.
    The researcher then studied the videotapes to study the matches carefully.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 error was 1 2 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 referees 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’8 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 important.
The findings ofthe experiment show that( ).

选项 A、errors are more likely when a referee keeps close to the ball
B、the farther the referee is from the incident,the fewer the errors
C、the more slowly the referee runs,the more likely elrors will occur
D、errors are less likely when a referee stays in one spot

答案A

解析 由文中的he found that error8 were more likely when the referees were close to the incident得知。答案选A。
