LZ~这是我摘自语法笔记里的解释,我觉得说的很清楚,不知道LZ看过木有~看过请忽略我~~~
(B) Correcet;补全省略即there are fewer than one-quarter as many (as there were at the height of their popularity in the late 1950s); fewer修饰可数名词正确;one-quarter在此做副词修饰as many,后面不用再加of,类似于twice as many/much as。
(D) the number指代不清;the amount指代不清,只能修饰不可数名词;the number is less没有问题,less和smaller都可以修饰数字。
