[求助]og204答案(E)會不會有造成句意awkward!?

OG204. 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

答案是(E)

      可是(E)這個答案我是越看越覺得奇怪,因為感覺像是cattle breeders去acquire(獲得) certain characteristics而不是牛獲得.

      想請教各位NN是否我這樣的考慮是對的,或是我忽略了什麼.
