答案是A么？
B是明显不行的，如果which是做从句主语，就没有for了，或者说，有for的情况下，要补个先行词
for which一般是which做状语的一部分

应该选D吧~正确答案~B 不对，因为For which 指代的应该是 the cost of higher education这个目的状语，这样的话从句就没有主语了。A我觉得ING短语做伴随不好，因为逻辑层次混乱~

instead of感觉不是很好，因为如果是作为名词修饰话，应该和which一样，就近做修饰比较好
如果是作为副词性修饰的话，它并不是修饰主句的

我prefer A的原因是，将主句主语作为paying发出者，整个逗号后面的部分修饰整个句子

共探讨，答案是撒？有人贴一个不？

A中是没有形成对比的感觉，还有paying表伴随状态或者是主动的状态，用在这感觉不适合

A
I'll assume "Scoetop" is meant to be Scoretop.  

"previously paying $7 per year" should refer to the students, which would make it a noun modifier, which is required to be placed next to the noun it modifies.  It isn't.  Incorrect.

B) this time the phrase isn't even clear - "for which was previously paid" makes no sense

C) "previously" is an adverb and should refer to a verb, but $7 is a noun - you'd need the adjective "previous" here.  And really you'd want to say something like "compared to the previous requirement of $7 per year"

D) I'm not a huge fan of this source.  I assume the reason to eliminate this one is non-specification that the $7 per year required previously was specifically required for higher education.  But I don't think the real test would make this the only distinction.  They might also try to claim something's wrong with "instead of" (rather than "as opposed to" in answer E), but instead of can properly refer to a noun, as it does here... so it's fine.

E) See above.

Bottom line: I wouldn't study this one.

这是国外一个GMAT研究网站上的解释……
她的结论是什么。。。

我倾向于选D。即便说A的paying修饰students，我觉得也不能用paying，因为这个现在分词和previously不符。

选D

A  分词短语被逗号隔开放在句尾，做伴随状语。句子结构是：students boycotted classes...to protest a law that...a year toward the cost of higher education,  previously paying $7 per year.

先看原句，paying做伴随状语伴随主句动作，明显是错的。

B for which介词加which形式，教你一个判断介词加which是否正确的捷径：把which所指代的对象恢复成一个陈述句，the cost of higher education was previously paid 7 USD per year. 不需要加介词对么？
再举个例子：
找一个需要加介词的句子：this is the house which i was born in
this is the house in which i was born
this is the reason which he did so much things for
this is the reason for which he did so much things.

那么，原话是否需要介词for? 而且我目前为止还没见过介词+which在逗号后的正确句子出现在OG里。

所以从逻辑上和GMAC的习惯上，这个for which都说不通。

C 过去分词短语作非限制性修饰成分，这个大结构看似没问题。但这个可以set off by comma的过去分词短语自己，previously修饰的是谁？肯定不是compared,那么这个短语里面已经没有其他词可以被副词修饰了，副词也不可能跳跃修饰到逗号外面去，因此C错。

D instead of...介词短语做补语，对higher cost的补充说明，整个句子在结构上和用词上找不出什么问题。

E, 错的一塌糊涂了，不用我说了吧....

7楼解释的很好

B的错误不是for which吧?
我觉得说成for which $7 was paid per year 就对了
