How do the airlines expect to prevent commercial plane crashes? Studies have shown that pilot error contributes to two-thirds of all such crashes. To address this problem, the airlines have upgraded their training programs by increasing the hours of classroom instruction and emphasizing communication skills in the cockpit. But it is unrealistic to expect such measures to compensate for pilots' lack of actual flying time. Therefore, the airlines should rethink their training approach to reducing commercial crashes.

Which one of the following is an assumption upon which the argument depends?

ATraining programs can eliminate pilot errors
BCommercial pilots routinely undergo additional training throughout their careers
CThe number of airline crashes will decrease if pilot training programs focus on increasing actual flying time
DLack of actual flying time is an important contributor to pilot error in commercial plane crashes
ECommunication skills are not important to pilot training programs

正确答案: D

在同一题目的选项中出现了strengthen 和assumption选项，容易混淆怎么办？请高手指点！

assumption取非原文不成立，assumption真包含于strengtnen中。
一题：D取非，flying time不重要的话，原文说“培训没有fling time 就不成功”肯定错。
C取非，培训有flying time 也不一定成功，不能说明原文说“没有flying time就不成功”肯定错。这好比：有房的男人没有取到老婆的事实不能说明没房的男人娶不到老婆的论断是错的一样。抽象到逻辑层面只，由“A推出否B”真确不能判断“否A推否B”的真假。
二题：E取非，原文不成立。
D的话只是给出了一种合理解释，取非的话，任然可以有别的解释。

我也不知道我讲清楚了没。。。。。。
