请教大全193

193.                  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

答案是D,不是make sth sth吗?为什么这里正确答案是make sth as sth呢?

谢谢!

"如果D的时态对应不上，那么所有的选项都错，因为所有选项都使用一般现在时；make sth as的用法的确没见过，但是D并不是这种用法，make his letters the rival of才是D的真正结构make A B，而句中的as a group是修饰letters，如我们所说的：soccer as part of my life足球是我生命的一部分"

这是前人讨论过的.我同意这个看法. as a group可以做为插入语看.
