The human nervous system and a telephone system superficially resemble each other, not only because the former carries information in the form of electrical impulses and because all of its neural pathways converge in the brain and spinal cord, which together form a kind of central exchange.

(A) The human nervous system and a telephone system superficially resemble each other, not only because the former carries

(B) The human nervous system and a telephone system bear a superficial resemblance because they both carry

(C) The human nervous system bears a superficial resemblance to a telephone system both because the former carries

(D) Superficially, a telephone system resembles the human nervous system both because they carry

(E) There is a superficial resemblance between a telephone system and the human nervous system, not only because they both carry

答案是C，可是BD该怎么排除？

B的话，根据平行应该是both carry and verb。可是这里是xxxxx and because，所以划线句就应该是both becuas ...

太感谢你了！

那我在下面贴出Ron对于B的评论吧


also, in (b), the pronoun "its" is completely stranded; there's no antecedent for it anywhere.
takeaway:
if a sentence contains a COMPOUND NOUN (X and Y), you CANNOT use a pronoun to refer to just X or just Y, unless you use "the former" or "the latter" to make the distinction explicit.
* see #109 in the yellow og11. in that problem, all four of the incorrect answers try to use the singular pronoun "his" to refer to 1/2 of a compound noun. that's forbidden.
DO NOT post additional details of that problem here.
* this rule still holds even if X and Y take separate pronouns.
for instance:
joe and jane both have prestigious jobs, although her salary is much higher
would still be disallowed under the strict rules generally endorsed by the gmat, even though "her" can only refer to jane (since joe is male).
in this case, you'd just have to substitute "jane's" for "her".
that's the way it goes.

之后对于D的解释

i would agree with you here: it's technically incorrect to use "they" because there is no place in which both systems are mentioned at once

B的话，根据平行应该是both carry and verb。可是这里是xxxxx and because，所以划线句就应该是both becuase的结构，不是not only because的结构，

在CD中，D被踢出局的原因在于这个they ,they作为代词的使用原则是：1.有先行词的存在 2. 先行词和代词单复数一致
可是D中的they没有任何一个名词的单复数能够和they匹配的

lz千万别跟我说a telephone system和the human nervous system啊，这两个system在D中可是分开的，当中有个resembles，所以不是一个整体不能作为they的先行词
