Mixed with an equal part of water, ethylene glycol, a compound commonly used as an automotive antifreeze, is effective at temperatures as low as –30 degrees Fahrenheit.
A. temperatures as low
B. temperatures so low
C. as low temperatures
D. as few
E. as little

A正确。
语法笔记中C给出的解释是：at后面缺少名词作宾语

语法笔记马上跟着一道类似题
prep 2-9 The Environmental Protection Agency frequently puts mandatory controls on toxic substances that present as little risk as one in a million chances to cause cancer.

(A) as little risk as one in a million chances to cause
(B) as little risk as one chance in a million of causing
(C) as little risk as one chance in a million that it will cause
(D) a risk as little as one chance in a million for causing
(E) a risk as little as one chance in a million for it to cause

那为何此处present不要直接跟名词risk作宾语了?
期待NN,谢谢~!

如果第二题里面有选项是a risk as little as one chance in a million of causing应该是比B更好的选项。sc永远是选美，不是选择绝对。
