GWD-8-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

it is less than one-quarter of that amount
选C还是D呢，我觉得选D，答案选C，there be句型不是很不好嘛

据说新prep里面官方答案是B。
马后炮地说一下吧。
很多时候句型问题其实是其次，最重要的是表意清晰，这题考点是可数与不可数，所以关键在句首的“fewer”&“less”之比，以及句末的“many”&“amount”之比。
drive-ins是可数的，于是对应“fewer”和“many”，“less”和“amount”均修饰不可数名词。所以选B。
之前讨论帖里面有一个问题是修饰百分比和分数的时候，无论可数不可数，都用“less”而不用“fewer”。现在看来GMAC考察重点不是艰深晦涩的语法知识，而是如何运用语法表意清晰。

答案是B，A，E项less用于比较不可数名词，而且A项有fracture，E项it没有reference， amount是修饰不可数名词的，drive-in可数，和there be句型无关。
