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.
