Investigators concluded that human failure was not responsible for the fatal airplane crash last August, and since that time new and more stringent rules for identifying and reporting mechanical problems have been in effect. That accounts for the fact that reports of airplane mechanical problems have increased in frequency by 50 percent since last August.

Which one of the following is an assumption underlying the argument in the passage?

(A) Airplane travel is still relatively safe, despite the increase in reported mechanical problems.
(B) Mechanical problems in airplanes have increased dramatically since last August.
(C) Mechanical problems in airplanes have not increased by 50 percent since last August.
(D) Airlines are less reluctant to report mechanical problems than they previously were.
(E) Mechanical problems in airplanes have become easier to detect since last August.

D.

argument holds only if:
new and more stringent rules for identifying and reporting mechanical problems help detect mechanical problems easier.

C)...if "Mechanical problems in airplanes have increased by 50 percent since last August" then "the new and more stringent rules for identifying and reporting mechanical problems" had not the mentioned effect.

This CR falls into casual-assumptioned type. To crack the conclusion that more strict rules account for the increase in the number of reporting mechanical problems, we should question if there's an alternative to the cause/ strict rules. There's one possible alternative: the mechanical problems in airplanes have increased, which led to the increase in the number of report. C helps us eliminate this alternative. C it is.

One more for C.

Even if airline is still reluctant in reporting the mechanical errors, the new and more stringent rules will do that: detecting and reporting the errors. So D is not the assumption.

Very unsure about this one, but I would choose D

because if airlines were more reluctant to report mechanical problems then we would noz have a 50%+ increase in frequency since last August.

This is a clear C. C doesn't pass the denial test. If C wasn't true, then the argument would not be soundless, because the real cause could be what introduced in C.

I will go with C on this...

C implies that mechanincal problems existed before...but were not reported...now they are reported...but that doesnt mean that mechanical problems have escalated...just that airlines are now reporting them....

if C were not true the argument would not stand...

E mechanical problems are easier to detect now since last Aug which implies more number of reports of such problems.

Is this making sense as an assumption negation test also succeeds.

I just PM`d Rahul about this problem so hopefully we can get an OA sometime soon. (C) makes sense because the same mechanical problems would have been difficult (or impossible) to detect prior to the new restrictions.

OA please.

C is the best. We are asked to detect the assumption. If C is not true we can not conclude that the stringent rules are the cause to explain the increase in the reports of airplane mechanical problems.

The argument says that the increase of reported problems is due to the new strict rule.

If (C) is negated, then it's not due to the rule, but due to the increase of problems itself.

(D) would have been the answer if it said "...were not less reluctant"
