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?
答案是A:More than one or two airplanes were scheduled for the nine canceled flights.
since it is unlikely that Swift would have the mechanical problems with more than one or two scheduled flights on a single day
这句话里面的 more than one or two scheduled flights到底应该怎么理解?是一到两个航班还是一到两架飞机?
以前的很多人都直接就把这句话理解成一到两架飞机了,……
我怎么觉得应该说的是 不可能有比一到两次还多的航班被取消是因为机械故障啊??
如果说不可能有一到两次以上的航班被取消是因为机械故障,那么这九个航班中最多只有两架飞机出故障导致停飞了,因为如果这两架飞机飞了九个航班,那么一定是九个航班都是出了机械故障所以停飞,那么就违背了题目中不可能多于两个的要求了,所以A的假设已被包含在这句话中,如果是后者,不可能有一到两架以上的飞机出故障,而且又有两架以上的飞机在飞这九趟航班,那么肯定有别的原因了,那就是A了,但是如果是后者的话,为什么不用more than one or two airplane而是用flight??难不成airplane=flight,那这样的话不是很混乱?或者说这道题还有别的什么说法?求解释

flight is 航班.
It is unlikely that Swift would have the mechanical problems with more than one or two scheduled flights on a single day. This simply means that "it is unlikely" not "it is impossible." This premise says that mechanical problems only is unlikely to cause delay of more one or two scheduled flights on a single day. But your deduction of "因为如果这两架飞机飞了九个航班,那么一定是九个航班都是出了机械故障所以停飞", is wrong. Remember "unlikely" is not "must not."作者: sunflower88 时间: 2011-6-15 06:31
