One more vote for option B.
we need 'has' here .. Eliminate option A, D and E. option C is wordy.

B is wrong since the Subject here is processes (see the sentence after conjunction and) and this should use have.

I shall go with A even when this is passive voice. It uses not X buy Y also.


Thanks for great question.

Please post OA.

"Research" is the subject, and "have revealed" is the verb. Everything between them can be mentally deleted as extraneous.

Error #1 - Subject/Verb disagreement. We need the singular "has".

Eliminate A, D, and E.

Let's look at the differences between B and C:

B: processes THAT produce and make it understandable..._____ instead of ______.
C: processes BY WHICH IT IS produced and understood...not ______ but ______.

They are very close here. I don't see anything specifically idiomatically correct, but I would now choose B because it is more actively constructed.

Error #2: Active Voice/Passive Voice

"by which it is..." is just a more wordy and passive way to say "that".

IMO: B

C looks clearer than B.

(B) Research during the past several decades on the nature of language and the processes that produce and make it understandable has revealed great complexity instead of underlying simplicity.

it says "processes that produce and make it understandable has revealed great complexity instead of underlying simplicity". i am not sure whether processes can produce and make the language understandable.

According to me

produce and make share the same object.

OA is B

Hello Vivian,

B seems to be right since it is in the "Active" voice.

But doesn't the GMAT prefer "rather than" in place of "instead of"?

Thanks!

What is the difference between 'XX instead of YY' and 'Not XX but YY'?

Are they same or suggest different meaning?

Pls suggest

I have a question:

"please clarify that object of the verb "produce" is missing here and also that the object can not be implied". I do not understand it and would like to know this rule. (Mundasingh123, Help!)

Thanks in Advance.
