If it is just the GMAT, It will be enough to know that the comparison is intact only in C and all others are faulty. So tick C and keep going without bothering about the accompaniments. The mention of bodies or body is just to hoodwink the candidate away from the comparison

However, if it is for the sake of knowledge, then I think both body and bodies are correct and one can cite umpteen instances to support each case.

I think the factor which makes C correct is the use of 'as' instead of 'like'. The latter is used for comparing two nouns. Here, we are not comparing nouns but rather the fact that mammals also have clustered nerve cells.

Hi All,

Unlike other arachnids, which have their nerve cells evenly distributed along their bodies, the scorpion’s nerve cells are clustered in its head, like a mammal’s.

Error Ananlysis:

This sentence presents contrast between two illogical entities – “arachnids” and “the scorpion’s nerve cell”. Since “arachnids” is in the non-underlined portion of the sentence, it should be contrasted with the “scorpion” itself and not with its nerve cells.

POE:

Choice A: bodies, the scorpion’s nerve cells are clustered in its head, like a mammal’s: Incorrect for the reason stated above.

Choice B: bodies, the scorpion’s head had a cluster of nerve cells, as a mammal does: Incorrect. Here the “arachnids” have been illogically contrasted with the “head” of the scorpion.

Choice C: body, the scorpion has a cluster of nerve cells in its head, as a mammal does: Correct. This choice presents the logical contrast between “arachnids” and “scorpion”.

Choice D: body, nerve cells are clustered in the scorpion’s head, like a mammal’s: Incorrect. Here the “arachnids” have been illogically contrasted with the “nerve cells” of the scorpion.

Choice E: body, a cluster of nerve cells is in the scorpion’s head, like a mammal’s: Incorrect. Here the “arachnids” have been illogically contrasted with the “a cluster of nerve cells”.

Hope this helps.
Thanks.
