22．  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

Parallelism + Rhetorical construction

The sentence gives two reasons that cattle breeders use crossbreeding；these reasons should be introduced in parallel ways with the word partly．The infinitive to acquire clearly and concisely conveys the purpose of the crossbreeding．

A  In part should be partly；use of relative clause is ungrammatical．

B  In part should be partly；wordy and awkward use of prepositional phrases．

C  Because of suggests that crossbreeding has occurred because the steers have already acquired certain characteristics．

D  Passive voice should be acquired by is awkward and illogical．

E  Correct．In this sentence，the word partly is used to introduce both reasons；the phrase to acquire certain characteristics is clear and concise．

The correct answer is E．

很想问这个平衡结构:...partly to....and partly because+句子?? to 和后面的 because不平衡啊

为什么不是:...partly because+句子....and partly because+句子,选项D.虽然用了被动.

感谢!

我觉得句子的主语是cattle breeders,主动比被动好，考点不只是平行结构。另外可能就是OG上说的D选项不符合逻辑吧，请指教。
