定语从句that的位置

wakeup001

The organic food industry has organized a successful grassroots campaign-using Web sites, public meetings, and also mass mailings-that have convinced the Department of Agriculture to change the proposed federal regulations for organically grown food.
A using Web sites, public meetings, and also mass mailings-that have convinced 
B using Web sites, public meetings, and mass mailings-that has convinced 
C by using Web sites, public meetings, and mass mailings-in convincing 
D by the use of Web sites, public meetings, as well as mass mailings-that convinced 
E which used Web sites, public meetings, and mass mailings-in convincing

一道prep，除了大家讨论的by的问题，我的疑惑是，that在这里会有指代mailings的歧义么？是不是应该放在campaign后面更好，谢谢！

楼主你好，这道题非常烧脑子，以下是我的见解：

首先回答你that 指代是否有歧义的问题，一般来说，像这种campaign-using Web sites, public meetings, and also mass mailings-that，Noun+修饰Noun的并列短语，然后加代词that,不会有歧义，可以确定是that是修饰前面的Noun的。

然后看题目:
A 错误 是因为Campaign是单数 have不对
B 正确
先看D中的搭配：XXX，XXX，and（also） XXX的搭配结构是不能够替换为as well as的

然后看最难的C E，这里我理解了很久，是之前看的ron的解释才明白：
CE 中两个错误，第一个：

* if you say "subject + clause + IN VERBing", then subject + clause must be an ACTUAL PART of the action of VERBing.
e.g.
i solved all the problems in OG12 in preparing for the GMAT.
--> notice that solving the problems IS ACTUALLY PART OF preparing for the test.

第二个错误，就是句子意思:
* if you say "subject + clause + BY VERBing", then "by VERBing" must explain HOW the main clause occurred.
e.g.
i prepared for the test by reviewing takeaways on the MGMAT forums.
note that the boldface clause describes HOW i prepared for the test.

choice (c) means that using websites, etc. was how the industry organized the campaign -- in other words, they used the websites and public meetings to organize the campaign in the first place. that's an incorrect meaning.
(the campaign ITSELF used these things; the correct modifier in (a) and (b) shows that relationship.)

如果有问题，欢迎交流，这两个选项确实比较难。斜线部分来自：https://www.manhattanprep.com/gmat/forums/the-organic-food-industry-t6929.html

不要等待验证

两个连词符中间的东西不是相当于同位语，可以去掉嘛0.0

谢谢！非常详细！因为我在另一道题碰到，SVO，when从句，that****这个选项就被排除了，看到的解释就是，that指代不清，根据逻辑应该指代前面的O，但引起了指代歧义。。。所以，这边的破折号插入语是不会歧义，但是从句会引起歧义？还是说只是不优选而已！
再次感谢！

能否提供一下原题？

Because she knew many of the leaders of colonial America and the American Revolution personally, Mercy Otis Warren was continually at or near the center of political events from 1765 to 1789, a vantage point combining with her talent for writing to make her one of the most valuable historians of the era.
Aa vantage point combining with her talent for writing to make
Ba vantage point, when combined with her talent for writing, that made
Ca vantage point that combined with her talent for writing, and it made
Dand this vantage point, which combined with her talent for writing to make
Eand this vantage point, combined with her talent for writing, made

OA:E  除了语义外，搜网站上的分析有说，B选项that指代不清. 所以说，that 跟在插入语后面，插入语可以省略不看？还是也只是不优选。。。
