In recent years cattle breeders have increasingly used crossbreeding, in part that their steers should acquire certain characteristics and partly because crossbreeding is said to provide hybrid vigor.

(A) in part that their steers should acquire certain characteristics

(B) in part for the acquisition of certain characteristics in their steers

(C) partly because of their steers acquiring certain characteristics

(D) partly because certain characteristics should be acquired by their steers

                      (E) partly to acquire certain characteristics in their steers

为什么不选D，与后面partly because 对称

同问恩~~~

如果前面的句式也是partly because,那么后面就不会再出现一个partly because，and后就直接crossbreeding...

你见过because ...and because...吗？

恩~~好象是没有~
那么请问LS大牛~~~：）是不是理论上是要平行的，但是这里因为没有这个用法，考虑到这个原因，所以把前面部分保留PARTLY。。。用TO表目的~？

我不是大牛，今天刚开始正式备考，呵呵。

你自己都分析出来了。但他的平衡应该是partly and partly.跟to 和because莫关系。
