When drive-ins were at the height of their popularity in the late 1950s, some 4,000 existed in the United States, but today there are less than one-quarter that many.
there are less than one-quarter that many
there are fewer than one-quarter as many
there are fewer than one-quarter of that amount
the number is less than one-quarter the amount
it is less than one-quarter of that amount
请看讲解视频
1.措辞，不能用Less，因为比较的是数字，是可数的，ADE错
2.idiom: ono-quater as many表示同样的数量。
同理还有twice as many.
3.一致，there are和Less,that the amount一看就不一致。AC错
4.the amount是指代不可数的，C就不一致，D的the number和the amount不能对比，CD错
fewer可数，less不可数，amount代不可数，number代可数
