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

I believe it is (D). I came close to chosing (C).

The author says that lack flying time cannot be compensated by training on other factors. That means lack of flying time must an important factor.
(C) is a trap because if we negate (C) we get

The number of airline crashes will not decrease if pilot training programs focus on increasing actual flying time.

Well this could be true if the airline companies just focused on more flying time and other factors could lead to crashes. This does not break the author's argument but (D) does.

1) How do the airlines expect to prevent commercial plane crashes?

2) Studies have shown that pilot error contributes to two-thirds of all such crashes.

3) 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.

4) But it is unrealistic to expect such measures to compensate for pilots’ lack of actual flying time.

5) Therefore, the airlines should rethink their training approach to reducing commercial crashes. <--conclusion

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

(A) Training programs can eliminate pilot errors.
- No. The author here is challenging airliens to rethink their trainig approach by providing more actual flying time. A is out.

(B) Commercial pilots routinely undergo additional training throughout their careers.
- If so, any form of training will do. B is out.

(C) The number of airline crashes will decrease if pilot training programs focus on increasing actual flying time.
- C is close, but 'will' says that the number of crashes decreasing is definite as long as there is an increase in actual flying time.

(D) Lack of actual flying time is an important contributor to pilot error in commercial plane crashes.
- This is the assumption required. If lack of actual flying time contributes to pilot error in plane crahses, then the pilot should be given more actual flying time so he/she becomes more proficient.

(E) Communication skills are not important to pilot training programs.
- Out of scope.

D is best.

Just to touch on a little bit more on negation here:

If we negate (D), then it will read as:

Lack of actual flying time is not an important contributor to pilot error in commercial plane crashes.

Obviously, by negating D, the conclusion can no longer hold.

However, if you negate (C), then it will read as:

The number of airlines crashes will not decrease if pilot training program focus on increasing actual flying time.

Okay, by negating this, we know that the number of airline crashes will not decrease, but it does not improve either. So negating C does not hold up the conclusion.

OA is D. This the answer from Ron expert

this is a good use of the reversal method for (d).

the problem with (c) is that it implies that increasing the flying hours, all by itself, WILL decrease the number of crashes.
this definitely isn't necessary to the argument (which strongly suggests that a decrease in crashes will come from a combination of extra flying hours + other mentioned factors, such as "classroom instruction" and "emphasizing communication skills in the cockpit").

(A) Training programs can eliminate pilot errors. - It is already stated in the argument. Cannot be an assumption. Argument talks about increasing the training programs. - Incorrect

(B) Commercial pilots routinely undergo additional training throughout their careers. - This is also a given piece of information which can be inferred from the given passage. - Incorrect

(C) The number of airline crashes will decrease if pilot training programs focus on increasing actual flying time. - The use of words like "will" makes it an obvious thing. Focusing on actual flying time may not decrease crashes. - Incorrect

(D) Lack of actual flying time is an important contributor to pilot error in commercial plane crashes. - "Important contributor" states that the lact of actual flying time is one of the contributors for pilor errors. This fills the gap in the argument. Hence this is the assumption - Correct

(E) Communication skills are not important to pilot training programs. - It can be considered to be out of scope - Incorrect

Hi src_saurav

E is a classic GMAT trap which talks about the premise rather than the assumption

Simplifying the argument:

Premise1 : Currentlessons focus on in-class lessons ( theory and comm)
Premise2 : The current type of lessons is inadquate

C: Increasing flying time during lessons will decrease the number of crashes

This is a logical gap type question.

To complete this argument.

Current lessons are inadequate. A: Because lack of actual flying time is causing error. So increasing flying lessons will decrease the number of crashes.

E panders to premise 1. It has nothing to do with the assumption or conclusion of the author
