[語文] feifei logic 23

[shyuan (.)]

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?

(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.


ans: A

有點不是很清楚選項A的意思

先謝謝大家~~~

推 Vinicks:結論:肯定會有其他原因導致九個航班被取消
→ Vinicks:作者依據:因為SA公司不可能會有1或2個航班被取消掉
→ Vinicks:如果要成立的話 就要(A) 因為要有超過1個貨2個飛機是被排
→ Vinicks:定在這九個飛航航班中 這樣才能說是有可能除了機械故障
→ Vinicks:會導致這九個航班取消 如果這九個航班都是SA公司那1或2個
→ Vinicks:因為機械故障取消的行班飛機的話 那此結論就不會成立
→ chunning:這題好像是LSAT的邏輯@@?
→ shyuan:謝謝~~
