重问OG11-22,即OG10-204

204. 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

关于E&D的区别，以前的贴子已经有很多讨论了，

OG11的解释和以前的有不同，如下：

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

E：In this sentence, the word partly is used to introduce  both reasons; the phase to acquire certain characteristic is clear and concise.
 

问：以前都是理解为表示目的的状语重句和表示原因的状语重句并列。这个地方OG解释： partly is used to introduce  both reasons.关于都解释原因这个说法从何而来？

有个贴子解释：http://forum.chasedream.com/dispbbs.asp?BoardID=23&ID=42391说XDF老师说是前置省略。

E 省略了 partly ( because crossbreeding is said ) to acquire certain characteristics in their
            steers

似乎是表示原因。

还是不明白，谁能解释一下前置省略？
