关于目的to do和for doing的区别

LTT12345

感觉好像GMAT不大用for doing表示目的，不过在做GWD 的时候发现有这道题。

GWD-9-Q17:

Unlike most other mergers in the utility（公用事业，向公众提供天然气、水、电力、运输等服务） industry, which have been driven by the need to save money and extend companies’ service areas, the merger of the nation’s leading gas and electric company is intended to create a huge marketing network for the utilities in question with states opening their utility markets to competition.

A.    and electric company is intended to create a huge marketing network for the utilities in question with states opening

B.    and electric companies are intended to create a huge network for marketing the utilities in question as states open

C.    and electric companies are intended to create a huge network that will be marketing the utilities in question, with states opening

D.    company and electric company are intending to create a huge marketing network for the utilities in question, with states opening

E.    company and leading electric company is intended to create a huge network for marketing the utilities in question as states open

为什么E选项是正确的呢？

虽然觉得这个问题本身提的不是很清楚，句子也没写清楚，但是通过简单的“主谓一致单复数”判断，解题没有问题。
首先， the merger of the nation’s leading gas and electric company is intended to create a huge marketing network for the utilities in question with states opening their utility markets to competition.是个独立的句子，其主语是the merger，为单数。谓语是is intended to，是单数。同时meger of 后面需要是至少两个以及以上的对象，否则也不能merge了，所以后面meger of后面必须是复数。原文后面是gas and electric company，是个单数，所以错误。
下面一个个看选项：
A. 谓语是is，单数，正确。meger of gas and electric company，是单数，所以错误。
B.谓语是are，复数，所以错误。
C. 谓语是are，复数，所以错误
D.谓语是are，所以错误。
E.谓语是is，后面meger of gas company and leading electric company，是负数。两个都正确。
所以是E咯。
