        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?

(A) Training programs can eliminate pilot errors.

(B) Commercial pilots 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.（D）

       (E) Communication skills are not important to pilot training programs

答案是D，

我选C， 后面的解释说C是加强， 请NN指教一下，加强和假设的区别，如何区分选项是加强还是假设。感谢了 ！

谢谢楼上，虽然有22人看过，还是你愿意帮助，D我明白，但考试时候不可能知道答案再来分析题目。

我的问题是，或感觉是，C 取非，同样使the airlines should rethink their training approach就不成立了。

不知道问题出在哪里？

(C) The number of airline crashes will decrease if pilot training programs focus on increasing actual flying time.
