There is a clear 3-2 split among the answer choices between choices using idiom so much..as and choices using idiom not....but.
so much ...as is used incorrectly as it does not convey intended meaning. we can rule out A, B and D.
Also there are plenty other reasons making different choices incorrect.
"not discovering a point.....as that they failing to communicate it" is awkward construction and there is no verb in the sentence making option A incorrect choice.
option B correctly describes "do not discover" part but wrong for idiom and pronoun reasons "them" incorrectly refers to differentiation.
Option C correctly uses not but idiom to convey proper meaning.
Option D contains same errors as A.
Option E removes the but from idiom not but and also produces verb missing error.

hi,
we are familiar with parallesism like not only x but also y
Another parallesim in Gmat is Not so much x as Y

In these context, only A B D remain.

Here point of differentiation is singulair so B out fail to communicate them.

we needs a verb after subject so A companies not discovering is noun phrase so out.


In C Not that and but that looks both show contrast looks not correct.

Option E out not have parallesim.


So Option D wins

If we look at the options C and D logically, C seems to convey clear meaning. It doesn't say that failing to differentiate is not the reason. It says that these companies do identify the actual reason, but they are not communicating it. It is implied that failing to differentiate is the reason.

Hi,
we have to go with original meaning so C is out ...
the original meaning saysthat one reason is more reponsible for the efeect than a second one.. so SO MUCH .... AS... is the correct idiom,
only option retaining the original meaning, parallelism and the correct idiom is D

I will change to C too. D seems a bit wordy. I went for D coz i felt it retained the original meaning but D has too many negators here and is unnecessarily wordy

Wordiness is not really the correct explanation - the comparison structure is altogether wrong in option D. The correct structure is:


(not) so + [adjective] + that + clause
I am not so happy that I will give you a treat.

OR (not) so [adjective] + as + noun/clause
I am not as/so happy as you (are).

You would notice that option D does not follow any of the above structures - the adjective is missing.

Hi sayantanc2k I know C is in different meaning with other choices, but I remember the idiom in GMAT is AS [adjective] + AS + noun/clause..,not SO [adjective] + AS + noun/clause. Don’t I remember wrongly?
