396. 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

根据以往的对称原则不是应该选D吗？

请各位NN赐教

是人要培育出牛的某种基因， 不是牛要培育出某种基因。 acquire 的动作发出方应该是breeders

大全里面的解释：

Choice E is best; it best indicates purpose for crossbreeding—partly to acquire. In A, in part that does not grammatically connect the underlined portion to the first part of the sentence (the independent clause). In both A and B, in part
            is not parallel with and
                partly in the non-underlined portion. Choice C causes a misreading, suggesting that the steers’ acquisition has caused the crossbreeding. D awkwardly and illogically shifts to the passive voice: certain characteristics should be acquired by their steers;) the steers, however, are not agents in the acquisition.
