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┬б┬п 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.

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

This is tough question.
I believe C and D are the contenders. I will go with D on this one.
The author is talking about not compensating actual flying time in the trainning. D nails hard on this one because if you negate D saying lack flying time is not an important contributor to the crashes then there is no reason to believe that the training program should compensate for lack flying time by actually providing more flying time.

C comes close but just stops short because, C is talking about increase in flying time. How much increase ? is the question here.
If you negate C you will see that increase in flying time will not decrease the number of crashes. So what ? the increase may be insufficient and ineffective. This may or may not break the argument.

Tough between C and D indeed. I think the fundamental flaw in C is that even if the number of plane crashes does not diminish, plane crashes related to pilot errors can. If the 2/3 ratio related to pilot can be diminished to say 1/3, the goal would be achieved even though the total number of crashed did not diminish.
