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.


what is the diff between C and D? why one is better (OA) than the another?


Between C and D - I believe D is correct. C goes too far. The stem only says that the training program cannot COMPENSATE for lack of actual flying hours - this can be interpreted to believe that Flying hours is a very important factor which has to be earned - it cannot be compensated for.

It still leaves scope for the fact that the trg program that includes increased flying time would help.

C goes on to say that simply by increasing actual flying time, the crashes will reduce. No indication is made to this effect in the passage.

D it is.
C at most can reduce pilot errors...we can't say that it will reduce plane crashes.

why not A ?

isnt that the basic assumption here that some kind of pilot training can avoid accidents?

Yea, why not A.

In the passage, the author asks How airlines can decrease c. flight crashes.

Then the answer is Training, different methods of it and so on. But author did not suggest any other ways to decrease the crashes such as swapping pilots, or renewing the system, and so on. Overal, Training.

Only thing the auther assumes is TRAINING(further) that might add to reduction of crashes.

I would go with A.

its quite confusing and pretty divided responses.
OA is D.

thanks everybody.

those who selected D, please explain why it is D for those who selected C or A or else..

Straight D

C) The number of airline crashes will decrease if pilot.......

The conclusion doesn't depend on this. Nor is that even the conclusion........ you're trying to infer something.

I would go with A.



Why not A . Because there are two arguments here.
1---Studies have shown ......skills in the cockpit
2--But it is unrealistic ................flying time.
Just for first argument 1 , A is fine .

But to consider assumptions taken for both the arguments I think C does a better job in including not just a training program but a training program with increased actual flying time.
So I guess C .
Before I started writing this I was sure answer is D but now I think C makes more sense.

D would be the right one.

The question asks about the asumption based on the argument that the author has given.
The argument here is 'Therefore, the airlines should rethink their training approach to reducing commercial crashes. '.

The key words here are : 'rethink' and 'approach' .
It says that the training approcah misses one of the important factor/contributor for reducing air crashes. It never argues that increasing the actual flying hours would decrease the crashes.

C goes extreme and unnecessarily takes this point into its assumption.

t is unrealistic to expect such measures to compensate for pilots’ lack of actual flying time

So the other factors should not be as important as "lack of flying time". So I go for D.

C only claims that "it would decrease", but never answers "by how much?". Rephrasing, it only says that the "lack of actual flying time" is a factor in the accidents caused. I think the argument's conclusion doesnt depend on it. The conclusion is whether the "lack of flying time" can be compensated by other measures.

Negate C and D

negating D breaks the argument

So go with D

this is an interesting question . i picked D in 1:27 min , looking at C , negation test got rid of it .
i simply rejected A but negating A yields funny result.

C takes the argument a little further and assumes that the training program will concentrate on increasing the flying hours.This has not been explicitly stated in the argument. Negating this does bring down the conclusion. But the option assumes a bit more than stated.

D If flying hours isn't that important then there is no need to rethink the training strategy. (By negation)

Thus D.

C has very strong language, D is relatively balanced, so D.

The auther argues "the airlines should rethink their training approach" that increases the hours of classroom instruction and emphasizes communication skills in the cockpit, yet does nothing (or least) about compensating for pilots’ lack of actual flying time.

Airlines may circumvent this arguement by saying that "we will increase actual flying time in our training programs". In other words, C is a reaction against this argument the Airline may take.

We are looking for an ASSUMPTION not a possible reaction.

The auther believes that the current training is useless because "lack of actual flying time is an important contributor to pilot error in commercial plane crashes."
So, no "actual flying time" but classroom and cockpit training, Pooooooooo.

=> D

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").
