89. A recent national study of the public schools shows that there are now one microcomputer for every thirty-two pupils, four times as many than there were four years ago.

(A) there are now one microcomputer for every thirty-two pupils, four times as many than there were

(B) there is now one microcomputer for every thirty-two pupils, four times as many than there were

(C) there is now one microcomputer for every thirty-two pupils, four times as many as there were

(D) every thirty-two pupils now have one microcomputer, four times as many than there were（C）

(E) every thirty-two pupils now has one microcomputer, four times as many as

I think "were" in C should be "was". However, E seems to be right grammatically. I don't understand "garble the 'one X...' construction, making four times as many reger illogically to pupils".

167. Neanderthals had a vocal tract that resembled those of the apes and so were probably without language, a shortcoming that may explain why they were supplanted by our own species.

(A) Neanderthals had a vocal tract that resembled those of the apes

(B) Neanderthals had a vocal tract resembling an ape’s

(C) The vocal tracts of Neanderthals resembled an ape’s

(D) The Neanderthal’s vocal tracts resembled the apes’（B）

(E) The vocal tracts of the Neanderthals resembled those of the apes

"Neanderthals"是复数,why not A, 至少对称啊.

167。我不知道你说的对称是指哪里的对称。

如果指的是those的话，逻辑上，those应该与a vocal tract响应吧？所以应该用that，而不是those.

 楼主提出的问题，以前没有考虑过。对呀，为什么是there were呢？而不是there

was?
