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

我在网上有查到解释如下：

1. 先判断宏观结构(破折号中的内容先不看),找出极傻错误 –杀A

2. as well as 不能等同于and使用. 使用示例：A and B, as well as C. / A, B, and C. –杀D

3．杀E, campaign后面跟which，发起者不对

4. B\C语义不同. B表示已经convince了, C表示在convincing中使用.而句中的successful表示已经成功了。 -牛

--------
但是个人觉得以上解释欠缺说服力。本人前阵子刚刚去考了gmat(2011.1)，在做sc的过程中起码碰上了5题带破折号的，所以是否有人能帮忙归纳下破折号的使用方法。尤其是此题中：using, by using, by the use of有何区别？

此外，此题中，正确答案B如果去掉破折号中间的内容，连续出现两次have done做谓语动词读起来也感觉非常奇怪（当然，语法上没有错误，只是与个人的语感产生冲突罢了）。

谢谢！

再顶一下~~我考试真的遇到好多破折号，现在想起来都一脸大汗。这么重要的考点，不在上面做些手脚GMAT也太好应付了吧~~
