(D) earned at a time in which aviation was still so
new such that many of the planes she flew were

OA IS E. But my doubts is related to option A.
OG mentions that A is wrong for two reasons:
too Wordy.
Wrong Idiom ( "So new X for Y" instead of "So new X that Y").

So my question is can GMAC Test Makers provides any SC questions with two options that are grammatically OK but one is wordier than others?

I mean in option A if we correct idiom issue then A and E differs in terms of concision.I have generally seen there is always some other grammatical errors besides wordiness in two closely related options.

Please clarify on this...

Hi Saransh

It is not frequently seen that 2 or more options are grammatically correct and one of them is correct just because of concision. There will definitely be more errors especially which are based on meaning.
Although two options can be grammatically correct but logically (meaning wise) only one will be correct.


In the example you cited there are more errors than just idiom and concision. Do you see any meaning difference in (A) and (E)?

Hints:
(1) The original sentence contains two independent clauses (known as Compound Sentence) but (E) contains only one independent clause (known as Simple sentence )

(2) try to differentiate the following parts of (A) and (E) respectively
(i) a time when aviation was still so new for many of the planes she flew
(ii) a time when aviation was still so new that many of the planes she flew


Please use the hints and find out the difference. In case you still find trouble, feel free to ask questions.

even if you make the idiom oki in A still A would be inferior to E .option A is trying to put 2 facts into parallel structures when in fact there is no need to do so !! .the fact after "and" is just an extension of the first mentioned thing.so all we need is a modifier rather than a parallel structure as is done in A
also i feel that explanations of OG are very poorly written .to just state that something is awkward/too wordy is nothing but poor explanation !!
