GWD8-Q41

When drive-ins were at the height of their popularity in the late 1950’s, some 4,000 existed in the United States, but today there are less than one-quarter that many.

A. there are less than one-quarter that many

B. there are fewer than one-quarter as many

C. there are fewer than one-quarter of that amount

D. the number is less than one-quarter the amount

E. it is less than one-quarter of that amount

这道题好像一直有争议，现在新版PREP既然已经明确了答案B,请各位NN来给讲讲吧。其实CDE, 翻阅以前的讨论帖，我已经知道错在哪里了。可是A呢？还有 as many as 的结构为什么可以省略？

请大家指教！！！！

相同的题目最好在一个帖子里讨论这样不会重复劳动了。
