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 problems 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.

想了很久不知为什么A对

A里的were scheduled for the nine canceled flights不理解

谢谢大家的帮忙！

我也想问

因为有9次航班被取消 并且since it is unlikely that Swift would have the mechanical problems with more than one or two scheduled flights on a single day 意思是一般因为机械故障取消的航次不超过1，2个  ＝＝＝》别的原因    所以 如果不是好多架都坏了的话 就不能推出有别的原因

还是推不下去

一天里多于一两个飞行任务的飞机不会有机械故障，要推出9个被取消的飞机里有一些是因为别的故障（而不是机械故障），就应该假设有一些飞机一天里只有一个飞行任务

那么这跟A有什么关系呢？

谢谢 近一步指教

对答案取非，得到less than one or two airplanes were scheduled for the nine canceled flights. 也就是只有一架飞机对应九个飞行任务，如果因为这一架飞机的机械问题，造成nine flights conceled,那就不会有什么其他的原因了，因为飞机只有一架。
