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 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.

assumption事我最害怕的题目，此题请教解题思路。 我看不出a与题目的关系：题目讲的是飞机取消和机器故障的关系，但是a好像讲的是一两架飞机代替9架飞机飞？满头大汗

weiyu gg,实在不好意思，这题他本身确实是没有问题部分的，后来找了个补充：

23题干：The argument depends on which one of the following assumptions

被assumption搞得焦头烂额！

偶当时没敢选这个答案，是觉得它是原文的重述，假设好象一般不这么出现
