ffice" />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. fficeffice" />
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.
我觉得一个选项都不对，请指教，谢谢！
如果按照mariezhu兄的说法，我觉得题目说的有问题，
On a certain day, nine scheduled flights on Swift Airlines were canceled
然后，since it is unlikely that Swift would have the mechanical problems with more than one or two scheduled flights on a single day
我觉得第2句话得scheduled flights应该该成airplans才能理解。
前面已经说了9个scheduled flights canceled, 后面又说不可能有more than one or two scheduled flights有机械故障，真的不知道在说什么？如果第2句该成airplans，正好是一个桥梁型的假设，在scheduled flights和airplans之间的桥梁。
请教高手，你们怎么第一遍就知道原文中第一个flight是航班，第2个flight是飞机？？
郁闷中!!!!
其实,A选项是排除只有一个飞机飞9个SCHEDULE FLIGHTS CANCELLED的可能. 因为如果只有一个飞机飞这9个FLIGHTS,则CANCEL的原因完全可能是机械原因. A选项排除这个可能,故为ASSUMPTION
另外,FLIGHT指航班,不是飞机
比较同意蝙蝠侠的观点，第二个要理解为飞机
否则讲不通了
