天呐这是我见过的最长的讨论帖。。。。。

讨论一下平行……
1)     Concrete nouns指things, people, places, and even time periods or certain events.
2)     Action nouns指to actions,常常由动词构成，如：eruption, pollution, nomination, withdrawal, development, change, growth。
3)    Concrete nouns不能和Action nouns平行。
4)     动名词分为Simple Gerund Phrases（名词的外表，动词的内在）和Complex Gerund Phrases（彻头彻底的名词），Simple gerund phrases从不和complex gerund phrases平行。
Eg. Wrong: I enjoyed drinking the water AND the wine tasting.
Right: I enjoyed drinking the water AND tasting the wine.
5)    只有complex gerund phrases能和action nouns平行。
Eg. Wrong: The rebels demanded the withdrawal of government forces from disputed regions, significant reductions in overall troop levels, raising the rebel flag on holidays, AND a general pardon.
Right: The rebels demanded the withdrawal of government forces from disputed regions, significant reductions in overall troop levels, THE raising OF the rebel flag on holidays, AND a general pardon.
6)     在一系列的action nouns中，总是选complex gerund phrase（常常有观察和of），而不是simple gerund phrase。
 ----以上摘自manhattan SC



not but是平行结构。underlying simplicity是simple gerund phrase，great complexity是action noun（great只能做adj，adv，n），这两者不平行。所以排除BC
instead of=rather than，都是prep，加ving。
主语research是单数，用has，只剩A

哈哈~~~讨论了好久啊

我还是支持选C

天哎。。居然讨论了十年。。不枉我做过此题。。。

选A 吧 ~~觉得A 的表达更符合GMAT的一贯风格 主动优于被动~~~相比较而言 C表达更绕 不直接 ~

C 中 understood 前面必须要有 is
虽然现在 it is produced and understood 是很勉强的平行，但是试问语言怎么主动的understand sth? 谓语动词并列的话就是 by which it is produced and is understood， 但是就算这样，c也改变了句子本身的句意

神贴留名。倾向于A。

这个帖子好悠久了
我选的C, 但是后来发现确实和A语义不同了. 既然C没有其他的错, 还是尊重愿意吧.

这是我在某个gmat论坛上找到的一个GMAT instructor的回复，先给出link：http://www.beatthegmat.com/nature-of-language-t91077.html

**********注意，link里的lz贴出的选项顺序不一样*****************


"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".

神贴了，讨论了10年~~竟然被这道题也困住了。
我直接选的C~~不知道为什么~~
不过这里的underlying 应该是adj把，修饰simplicity ，所以核心词还是simplicity ~~
