Pay attention to scope changes especially to sth can change itself over a time.

Such as
9 flights = 9 planes
cost or price of sth = amount of sth
part (white horse) = all (horse)
a specific thing = sth in general
past situation = current situation
A's (i.e retail store A) situation = B's (department store B) situation
A's situation = sth in general = B's situation
 
Just keep a note for all this kind of questions.  So everytime you see a scope change, you know that there may be a question there (but you must read the question stem carefully to make sure you answer the question asked. That is one of common traps, which I falled in several times)

以下是引用Justinchen01在2007-7-27 17:21:00的发言：

答案就是A啊

对A取非的话 如果只有一到两架飞架执行9个航班的话，一旦机器出现故障，那么九条航班同时瘫痪是很正常的啊，也就不会有题干中提出有其他问题的可能了。

正因为不止一到两架飞架，也就是很多飞架在执行这9个航班，那么同时瘫痪，就有问题的。

我是这样理解的。

这个最通俗，最易懂

同意上面说的,如果However, since it is
unlikely that Swift would have the mechanical problems with more than one or
two scheduled flights on a single day中的scheduled flights改成scheduled airplains 更像GMAT风格一点

看过之后明白了，不过题目的用词会产生误解啊

不知道是不是人家就这习惯，我自己读不懂而已。。。打击

Ordinarily, a cancellation is due to mechanical problems with the airplane scheduled for a certain flight. 真不知道这句话有什么作用。从答案来看，可以有其它的原因造成航班取消，那么，假设只有一架飞机执行9个航班，这架飞机的全体飞行员罢工造成9个航班全部取消，这不是与A相矛盾吗？题目没要求9个被取消的航班里面必须包含机械故障因素导致的停飞吧？
