OG Verbal SC中的一题求各路大神帮助及解释...

24. 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.----
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.

正确答案是E。这题明显是考parallelism啊.. 为什么E是正确的呢? 难道原因状语从句可以和不定式并列吗???
另外.. 我选择的是D, 虽然这个选项的被动语态有点redundant， 但是它也是个because从句啊， 可以和后面的partly because crossbreeding…… 平行呀。。

求大神解释! 谢谢你们无私的帮助!

D的语义不对，你翻译过来体会下语义。应该用不定式表示目的才对。
E虽然没有完美的形式，但是语义是正确的的。
所以ron说过，不要看到形式上完美的句子就选，有可能是trick。
