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

Goal/conclusion-airlines should rethink training approach

plan- why plane crashes happening…due to pilots error
but training program do not compensate for pilot's lack of actual flying time

hence training program is not effetive

options- A- can eliminate,,,then conclusion never says to rethink
B-if Pilots undergo constantly,,,eroors shud not ocucr,,still crahes r happening
C-this is answering properly,,
TRAINING PROGRAM IS lack of flying hours

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


Problem: pilot error accounts for 2/3 of commercial plane crashes. The plan is to reduce this ratio - ratio of number of crashes that result from pilot error to the number of crashes from all causes.

C says that increasing actual flying time will decrease number of airline crashes. Number of plane crashes may be reduced, but the the ratio of pilot error crashes to total crashes may remain same. Therefore this answer is wrong.

hope it helps

I applied to bridge the gap method here:
a number of airline crashes = reducing commercial crashes.
pilot training programs that focus on increasing actual flying time. = pilots' lack of actual flying time.

What subtle difference is the one that (D) scores over (C) ?

adkikani - surly tough one ! I am surprised how this is 35% medium question while more than 1400 have attempted.

premises:
A. Studies have shown that pilot error contributes to two-thirds of all such crashes.
B. 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.
C. But it is unrealistic to expect such measures to compensate for pilots' lack of actual flying time.
D. Therefore, the airlines should rethink their training approach to reducing commercial crashes.

Conclusion: the airlines should rethink their training approach to reducing commercial crashes. - yes you are correct on this front. - an easy way to identify this thing is use of because. a because of b/ b because of a . do the analysis and find which one make more sense.
Now a moment on vocab used in the conclusion. it says rethink. not changed not removed. this means airlines should re-evaluate its approach in this case. may be it is right may be it is wrong. watch out for the use of moderate vocab. none of the statements shows surity.

Pre-thinking: As we know there can be multiple assumption. here is my pre-thinking.
1. crashes can be avoided by increasing the hours of classroom instruction and emphasizing communication skills in the cockpit.
2. lack of flying time can not be compensated by classroom.
Let see what we can say about this actual flying time. Given the stimulus, are we sure, if this taught, it will decrease number of crashes. Think of it this way --- if you learned driving, good hands on, are you sure there will not be any crashes. Also study does not say that crashes are due to lack of this hand-on.

Which one of the following is an assumption upon which the argument depends? - mark the word argument - what reasoning's assumption in this case.

(C) The number of airline crashes will decrease if pilot training programs focus on increasing actual flying time. - very close answer. basically lack of flying time is real reason for crashes. if something will work on it, problem will go away till an extant for sure. now with the given word 'rethink', my take on this point is that increasing the flying time can result in improvement,but can not too.

(D) Lack of actual flying time is an important contributor to pilot error in commercial plane crashes. -- if we negate it, means this is not an important contributor, well then conclusion breaks.

i think D is the best between the two. Let me know if you find some gaps in reasoning.

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

Pre-thinking- But it is unrealistic to expect such measures to compensate for pilots' lack of actual flying time.

If the measures undertaken will reduce the crashes then no problem. No argument.

But author thinks otherwise that crashes will not reduce.

WHY?

Because author thinks lack of actual flying is important parameter in affecting the number of commercial plane crashes.


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

So till this point I know that lack of actual flying is important parameter in affecting the number of commercial plane crashes.

But Can I be sure that if flying time in training for pilots is increased then number of plane crashes will definitely decrease.

No.

One possibility - May be even if the flying time is increased still it needs adequate associated classroom training to be effective for pilots......

So let's say it's the balanced combination of classroom training and flying training that will be effective in reducing number of plane crashes.

But because only classroom training is being implemented then authors argument holds. I can eliminate C.



(D) Lack of actual flying time is an important contributor to pilot error in commercial plane crashes.

Matches our pre-thinking. Ans : D

Hope this helps!! adkikani

Source: LSAT


Pilot error ----> major contributor to crashes

To reduce crashes -----> upgrade training programs

Upgraded training programs ----> lesser/no Pilot error

lack of actual flying time ----> Inadequate Training programs

Hence lack of actual flying time ----> Likelihood of Pilot errors

I think the key to choose D over C, in this argument is that "nowhere in the argument it mentions that currently actual flying is part of the training programs, rather it only says lack of actual flying time"

Answer choice C mentions "increasing actual flying time", but we do not know if "actual flying time" is part of the training programs or whether if it is a part & it is currently inadequate & requires to be increased.

D is correct, firstly it uses verbatim "lack of actual flying time" and "commercial plane crashes" & secondly since the argument says upgraded training programs cannot compensate for "lack of actual flying time" hence Pilots are still susceptible to commit errors, hence actual flying time is important to reduce Pilot errors.


Answer D.


Thanks,
GyM

Unfortunately the pilots are waivered from inspections of their personal luggage, so a co-pilot can bring a gun onboard, shoot the pilot, and crash the plane down. I think the answer is if you take care of your pilots, inspect them to before allowing on board. Actually all airlines should rethink their training approach to reducing commercial crashes. I've just read on the new approaches here
