7.    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

答案是A，但我认为A中的produce后面难道不少对象么，that引导定语从句修饰process，produce后面应该跟上it，再and make it，不然意思就是produce it understandable？？

共享宾语了。而understandable是和make搭配的.

用by which是肯定不对了？

produced by the process,无此搭配？

for A :  produce and make it understandable--> where we might understand produce it understandable and make it understandable< the first part of which is nonsense> although the actual meaning should be " produce it / make it understandable.

forC:by which it is produced and understood, IMO, the expression is OK , however it uses a PASSIVE voice.

在我看来都有一些小缺陷。oa is A.就表明GMAc可以接受A的表达方式，不认为会其会对文意的表达产生影响。hehe

只能说A相对最优了...GMAC痛恨被动啊...
