Question

一道GMAT语法题。

The company is negotiating to sell its profitable credit card subsidiary, which it plans to use money from to acquire some of the mortgage –servicing operations that are being sold by troubled savings institutions.
A。Subsidiary, which it plans to use money from
B.Subsidiary, from which it plans to use money
C.Subsidiary, and it plans the use of money from that
D.Subsidiary and plans to use money from that sale
E.Subsidiary and plans the use of money from that sal
这是白勇语法里的题目，我不明白为什么选D， its pans to use...在原句里是做从句，也就是说原句是主从结构，但到了答案里却变成了并列结构，这不是违反了白勇总是强调的 句子重心问题吗，求解答，谢谢

Answer 1

如果要不违反“句子重心”问题，前提条件是原句是个正确的句子呀。
选项A本身（即原句）就是一个错误的句子，不能构成主从结构，因为which在句中指代 the profitable credit card subsidiary，把定语从句单独拎出来就是：it(指the company) plans to use money from the profitable credit card subsidiary是不通的，而正确的理解是use money from selling its profitable credit card subsidiary，但是sell...是个动词词组，而which只能指代名词词组，故这个句子是错误的，只有改成use money from that sale才正确。
因此，不得不将原本是主从结构的句子变成了并列句。
希望能看懂解释，供参考。

Answer 2

主句不是并列结构啊，答案中的subsidiary和mortgage是修饰的作用。指mortgage subsidiary这个分公司，前面那个which是修饰subsidiary的，而and只不过是连接了定语从句中的并列结构啊，你是不是没有弄懂这个句子的含义啊？？

你看原句， which it plans to use money 。。。这里是做从句，也就是说原句的结构是主句加从句的结构，但到了D选项，Subsidiary and plans to use money from that sale，这里的plans to use money 已经和主句成并列结构了。我看白勇语法这本书里总是强调句子重心不能改变，不能随意更改句子成分作用的，这个我不是太懂，所以问一下

Answer 3

额，看原句：company sell credit card subsidiary,which这个which指代不清，不能指代前面的句子，也不可能指代subsidiary，所以A不对。简而言之，就是从句使用错误。B同理，which不能指代to sell its profitable credit card subsidiary，B不对。C和E的plans the use of money属于wordy and
awkward,应该用plan to use.所以选D，参考。

你这种解释书上是有的，我的问题只是问 答案D， its pans to use...在原句里是做从句，也就是说原句是主从结构，但到了答案里却变成了并列结构，这不是违反了白勇总是强调的 句子重心问题吗
