说不清，帮顶。

At是介词，后面要求跟名词

所以选A不选C

支持楼上，
at as 连用有问题

alohabrian

请问as low temperates as中第一个as是adv吗？

songlovegt

应该是adv.
as    as 结构中，我觉得标准用法中间只能加 adj. 和 adv. 中间如果有名词还是 such     as更为标准吧，所以如果改为at such low temperatures as 应该是可以的。
但是经常可以看到 as low temperatures as 这种用法，但就这个题来看，GMAT 可能是不认可这种用法的
另查了Longman
as   as 例子里面没有插入名词的例子。

as...as 中间有加N的例子啊，如下：补充题78

78.   Although many Whites, noting the presence of some Blacks in the middle class, think that the time for enforcing civil rights measures is past, Blacks generally are aware that average-income and unemployment figures show as wide a radical discrepancy as ever.

as adj.  a  N. as...(注意：这个名词应带有不定冠词)

但是都没有看到过N是复数的情况。

as...as结构有强调形容词和副词的作用吧，所以总是只夹形容词或副词，或者也是先出形容词再补名词的。

但是还是没有明确的解释。期盼NN来解答。

我*覺得*C只是sounds bad(因為at as), grammatically 沒有錯.
let's check out an example:
P1-9: The Environmental Protection Agency frequently puts mandatory controls on toxic substances that present as little risk as one chance in a million of causing cancer.

P1-9可以寫成:
The Environmental Protection Agency frequently puts mandatory controls on toxic substances that present risk as little as one chance in a million of causing cancer.

我后来做题也遇到了一个 as + adj. + n. + as 结构正确的情况，具体在哪儿想不起来了。as...as... 中间是可以有名词的，我6楼的帖子错了，大家别被误导了。
