airplanes

According to government official involved in overseeing airplane safety during the last year, over 75 percent of the voice-recorder tapes taken from small airplanes involved in relatively minor accidents record the whistling of the pilot during the fifteen minutes immediately preceding the accident. Even such minor accidents pose some safety risk. Therefore, if passengers hear the pilot start to whistle they should take safety precautions, whether instructed by the pilot to do so or not.

The argument is most vulnerable to criticism on the grounds that it

(A) accepts the reliability of the cited statistics on the authority of an unidentified government official

(B) ignores the fact that in nearly one quarter of these accidents following the recommendation would not have improved passenger’ safety

(C) does not indicate the criteria by which an accident is classified as “relatively minor”

(D) provides no information about the percentage of all small airplane flights during which the pilot whistles at some time during that flight

(E) fails to specify the percentage of all small airplane flights that involve relatively minor accidents

I am pretty much sleepy now but will try to put together some words :)

A - Goes out of scope pretty much. There is no mention whether the govt officials are known or unknown.
B - This is not a criticism. Even if the suggestion doesn't work in 1/4th cases, it is still working in 3/4th. That is what the author is conveying.
C - Specifying "Relatively Minor" is not required here. How does it matter that to what level these accidents were minor, the main point being put up in this passage is about the relation between pilot's whistling and the accidents.
D - This rings some bells. For e.g., if in all the planes, pilot whistles, then it means that passengers should take safety precautions in every plane :) . So this can undermine the argument.
E - We are just talking about data of small airplane flights here. So taking percentage for small airplane flights w.r.t. long airplane flights etc should not matter because we are just concerned with accidents related to small airplane flights.

I am not sure if I have explained every point correctly :? But if you have any question, probably I can answer tomorrow when I will be fresh :)

By the way, what is the OA?

I believe the correct answer should be D
