(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
这道题，非常突出了GMAT考试的语义的理解，D句意是：部分是因为有些characteristics应该被steers得到。而E是：部分是（人）为了获得steers的某种characteristics.——很明显，其实不是牛要获得某种特征，是人要获益于牛的某种特征。
而且，根据平行句的主被动优选，D为被动，E为主动，未划线的and partly because crossbreeding （is said to） provide hybrid vigor实则为主动句，E一定是优选答案。
