Sentence Correction

In recent years cattle breeders have increasingly used crossbreeding, in part 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

A & B are out for using 'in part'
C is also out as it is passive.

D) There's no question of SHOULD here. The issue is meaning. The breeders crossbreed because they WANT something to happen.

E) It isn't as parallel as we'd like. It would be nice to say "partly to A" and "partly to B" OR "partly because of A" and "partly because of B".
Since there are no such options and this is still parallel enough (with the two "partly"s), and from there it's all about meaning.Correct.
IMO E

i think b seems correct answer
