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.
The argument depends on which one of the following assumptions?

More than one or two airplanes were scheduled for the nine canceled flights.
Swift Airlines has fewer mechanical problems than do other airlines of the same size.
Each of the canceled flights would have been longer than the average flight on Swift Airlines.
Swift Airlines had never before canceled more than one or two scheduled flights on a single day.
All of the airplanes scheduled for the canceled flights are based at the same airport.

这里flight跟airplane啥关系啊？

Check dictionary for the definition of flight.

是不是选A啊？
flight指trip through air, 我个人认为可以作航班解释。airplane指飞机。
9个航班可以由9架飞机执行任务，也可以由8架甚至1架飞机来执行任务。
本题题干中说明：一般而言，航班被取消是由于计划执行任务的飞机出现机械故障；接着又说一天之内不可能有多于1、2个航班出现机械故障，有些航班的取消可能是基于其他原因。
如果只有1架或2架飞机来执行9个航班的飞行任务的话，那么题干的说法将被反驳。所以我选A。
