请教：OG-SC-24？

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

A

B 略

Cpartly because of their stees acquiring certain characteristics

Dpartly because certain characteristics should be acquired by their steers

Epartly to aquire certain characteristics in their steers

答案：E

OG的答案是平行结构，D不应该是更平行的吗？

整个句子怎么翻译啊？？

    主体是蓝色部分Crossbreeding, 然后是红色部分和红色部分的to...... 部分平行对称！

另外，妹妹，你跑错问的地方了。这里是逻辑专区，所以没有人回答你。

楼上解释不对。

咋看之下d的确与后面更平行，但是d被动语态与前面主句就不平行了
