77. 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 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.
这道题C为什么不对呢？如果把C取非也削弱了阿
我的理解是因为飞机坠毁的三分之2原因是由于飞行员的操作错误，training的目的也是解决这个问题。所以选项C Lack of actual flying time is an important contributor to pilot error in commercial plane crashes 支持从新考虑培训方案。
C选项是够迷惑人的，有NN推荐避免错误的好办法吗？还是只能在做题时注意目的性
文中 非实践的学习不能弥补实际操作的缺少----}非实践的学习不能减少事故 所以中间省略的逻辑链条是实际操作的缺少导致至少大部分的事故。不知对否， 请指正。
