GWD-8-Q2:

C.      Jazz pianist and composer Thelonious Monk, who produced a body of work rooted

D.      Jazz pianist and composer Thelonious Monk produced a body of work that was rooted

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

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

问：1.数字多少的比较不是用great and small 吗？可以用few和less吗？还有其他用于数字比较的词汇吗？

2. 如D项中的the改为that，会比答案的C项要好吗？

第一题：如果说毛主席，就是chairmen mao，你说是不是重复？一个是头衔，一个是姓名，不冲突。

第二题，number和amount重复，不知道指的那个数字？4000？还是总数？因此指代不清。不是that和the的问题。
