Any reason why E is wrong?

Hi

(E) States that - " Most pilots who make errors in flying will repeat their errors unless they are retrained"

CASE I : Suppose 100 new pilots make a the same mistake once each
CASE II : Suppose 1 new pilots make the same mistake 100 times.

For both the cases, Training for the Pilots is essential. So that is why E does not make sense and can be eliminated also by the Negation Technique .

Please correct me if am wrong.

I chose "E". The thing with "D" is that it is not a presupposition nor an assumption to be made for the argument to hold, on the contrary, this is explicitly stated in the argument. And so if it is a simple restatement of part of the argument it cannot be a presupposition at the same time. In the case of choice "E", it states that "Most pilots who make errors in flying will repeat their errors unless they are retrained". The conclusion of the argument is that only after a pilot error has been analyzed and accordingly changes are made, then it can be ensured that the same type of error does not recur. It is therefore being assumed that the error would be repeated unless these actions (investigation and analysis of airline management, airplane design, training programs, etc.) are performed. Hence I chose "E"

Hope this helps.

Best,

I guess OA should be D... I came across a similar question in OG and the ans of that question was similar to choice D....

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.

How does E fit in the scope? Shouldn't A be the assumption?

The passage already states that the accidents are because of pilot errors ( "Instead of blaming an airline accident on pilot error, investigators should find out why the error was made" - this part implies that there was definitely a pilot error). Hence A is incorrect.

The argument is as follows:

Conclusion: ONLY analyzing airplane design, airline management, and pilot-training programs will ensure that an error is not repeated.

The word "Only" plays a vital role here, because it eliminates the possibility that there could be other ways by which repetition of errors can be avoided.

Thus the assumption is that there is no other way to avoid repetition of errors. If a pilot who makes an error learns from his mistake and does not make the error again, then this would be one other way of avoiding a repetition of error. Thus E must be assumption.

Please let me know if you still have doubt.

Hi Sayantan,

I have a doubt here... Here the question stem says that to avoid future error the investigators should investigate the error made by analyzing airplane design, airline management, and pilot-training programs. So if the result of an investigation of any of the three below aspects can not contribute to future prevention of accidents then how come the conclusion become true?

1. airplane design - suppose investigators say that airplane design is an important aspect of preventing future accidents, but assume in reality it is not an aspect.
2. airline management - suppose investigators say that airline management is an important aspect of preventing future accidents, but assume in reality it is not an aspect.
3. pilot-training programs - suppose investigators say that pilot-training program is an important aspect of preventing future accidents, but assume in reality it is not an aspect.

So D passes the negation test and IMO the best ans. What do you think in this case? Am I missing something?

In this forum also there is a OG 16 question on similar pattern( related to insurance and car driver) and the OA is E.

I went for E but many of people have said that D is the correct option. Can somebody sort out this confusion? If it's an Official question it would certainly have an OA!

An Expert's opinion will be greatly appreciated.

(E) Most pilots who make errors in flying will repeat their errors unless they are retrained.

Does it mean, SOME pilots who make errors in flying WILL/MIGHT repeat their errors EVEN they are retrained?

If so, then IMHO, changes CAN NOT be made to ENSURE that the same type of error DOES NOT recur and cause another accident, EVEN we analyze and retrain
Basically, the inclusion of MOST in E is confusing me.

Regards

I chose D because it sounds the most convincing as an assumption. It is also in line with the conclusion.

I feel E is wrong because, the accident could be because of management also. Assuming that pilots will make the same mistakes unless retrained doesn't sound logical and it doesn't fall in line with the conclusion.

Maybe I'm wrong. lemme know in such a case...
