606. 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.

(A) that produce and make it understandable has revealed great complexity instead of underlying simplicity
(B) of producing and understanding it have revealed not underlying simplicity but great complexity
(C) by which it is produced and understood has revealed not underlying simplicity but great complexity
(D) by which it is produced and understood have revealed great complexity rather than underlying simplicity
(E) by which one produces and understands it have revealed great complexity instead of underlying simplicity

Solution:

Subject-verb Agreement + Idioms

The subject "research" is singular. Therefore, the verb must be singular. B, D, and E are incorrect because these choices use plural verb "have".
In C, “revealed not X but Y” is not idiomatic.
A maintains subject-verb agreement through “…research(singular)…has(singular) revealed…”. Hence,
A is the best choice.
