Instead of blaming an airline accident on pilot error, investigators should find out why the error was made by analyzing airplane design, airline management, and pilot-training programs. For only then can changes be made to ensure that the same type of error does not recur and cause another accident.

Which of the following is a presupposition of the argument above?

(A) Pilot error is not a contributing factor in most airline accidents.
(B) Airline companies themselves should be the agents who investigate airline accidents.
(C) Stricter government regulation of airline companies will make air travel significantly safer.
(D) Investigators of airline accidents should contribute to the prevention of future accidents.
(E) Most pilots who make errors in flying will repeat their errors unless they are retrained.

Picked A. If we negate A, the argument falls apart.

It does not.

Nothing in the paragraph suggests that pilot error is NOT a contributing factor to airline accidents. Instead, it is merely suggesting that investigations should be more focused on other factors.

i would go for E...

My reason:

A) is wrong because pilot error is one of the contributing factor in airline accident.
B) is wrong because the whole argument is not about who does the investigation, but what should the investigation lead to
C) is wrong becoz Provides a solution, does not make any assumption to the argument
D) again, the argument is not focusing on who, but what should be investigated
E) ".....For only then can changes be made....." indicates that if pilots are retrained will future accidents be prevented.

D looks like it......

Investigator contribution should add more value is the assumption

I would have picked (D) if "should" were to be substituted for "would".
Should sounds, in that case, more like "must".
Correct me if I'm wrong.

(A) - if pilot error wasn't major contributing factor, then pilot-training programs wouldn't be mentioned by the author.

(E) makes sense, yet it is weak.

What is OA?

D is the answer. If the investigators find out the issue and then move on without contributing to the prevention of recurrence, then the argument falls apart.
