Byron possessed powers of observation that would have made him a great anthropologist and that makes his letters as a group the rival of the best novels of the time.
A. makes his letters as a group the rival of
B. makes his letters as a group one to rival
C. makes his letters a group rivaling
D. make his letters as a group the rival of
E. make his letters a group which is the rival of
考察agreement和make的固定搭配
首先根据句子分析发现是双定语: powers of observation that …and that …
这里的that是修饰 powers of observation,根据核心词原则,(A of B that ,that 修饰A),发现这里的that 修饰powers所以用复数形式make而不是makes,排除选项ABC
其次关于make的固定搭配是:make sth sth,所以选择D,选项中的as a group作为letters的后置定语,修饰前面的Letters.
E不选是因为wordy(which is )
