. 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 airline 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?

A.    Training programs can eliminate pilot errors.
B.    Commercial pilot routinely undergo additional training throughout their careers.
C.    The number of airline crashes will decrease if pilot training programs focus on increasing actual flying time.
D.    Lack of actual flying time is an important contributor to pilot error in commercial plane crashes.
E.    Communication skills are not important to pilot training programs.

讲解没看懂，C选项为什么不对呢？谢谢了

应该选D..文章的逻辑是
air crash因为人为错误多--所以增加培训--但是培训解决不了这个问题--因为培训弥补不了飞行时间的不足
推论中从人为错误直接跳到飞行时间，D选项弥补了这个gap
c是迷惑选项，因为training program和actual flying是两个不同的东西，文章没有说traning program can focus on increasing flying time.
