题23
On a certain day, nine scheduled flights on Swift Airlines were canceled. Ordinarily, a cancellation is due to mechanical problems with the airplane scheduled for a certain flight. However,since it is unlikely that Swift would have the mechanical problems with more than one or two scheduled flights on a single day, some of the nine cancellations were probably due to something else.
A.More than one or two airplanes were scheduled for the nine canceled flights
B.Swift Airlines has fewer mechanical pronlems than do other airlines of the same size.
C.Each of the canceled flights would have been longer than the average flight on Swift Airlines.
D.Swift Airlines had never before canceled more than one or two scheduled flights on a single day.
E.All of the airplanes scheduled for the canceled flights are based at the same airport

答案是A，能不能请大家帮忙解释一下A为什么是正确的啊！

若只有一种飞机，则虽然是9次航班，都可能是一种原因。但若是多种飞机，原因就可能不止一个了。
