prep2008 -sc 语法笔记勘误、查漏专贴

问一下prep2008 181里面提到的Manhattan模考题：

Antigenic shift refers to the combination of two different strains of influenza; in contrast, antigenic drift refers to the natural mutation of a single strain of influenza.
A. influenza; in contrast, antigenic drift refers to the natural mutation of a single strain of influenza
B. influenza, different than the natural mutation of a single strain, known as antigenic drift
C. influenza, in contrast to the natural mutation of a single strain, known as antigenic drift
D. influenza, different than antigenic drift, which refers to the natural mutation of a single strain of influenza
E. influenza; in contrast to antigenic drift, which refers to the natural mutation of a single strain of influenza

答案选A，B、D是由于different than的错误，E是因为分号后面接的是一个完整的句子而不是which引导的从句，问一下C主要的错误在哪里？求大牛解答一下，谢谢~

再问一道关于倍数的题目：
According to surveys by the National Institute on Drug Abuse, about 20 percent of young adults used cocaine in 1979, doubling those reported in the 1977 survey.
(A) doubling those reported in the 1977 survey
(B) to double the number the 1977 survey reported
(C) twice those the 1977 survey reported
(D) twice as much as those reported in the 1977 survey
(E) twice the number reported in the 1977 survey
OA：E。其中twice跳跃used cocaine修饰20 percent of young adults.
没有想明白，到底哪个是哪个的两倍？

In an attempt to guarantee the security of its innovative water purification method, the company required each employee to sign a confidentiality agreement prohibiting that its water purification methods be disclosed to companies using an analogous purification process.  
A.    prohibiting that its water purification methods be disclosed to companies
PREP解释
A中companies和an process单复数不匹配
不太同意此观点，因为就是有可能就是其他的公司使用的是一个相似的方法，，，，

PREP 216题补充部分关于主语比较，一个小细节错误了。

主语若相同 ，可省，但助动词不能省。如：
As a result of the continuing decline in the birth rate, [fewer people] will enter the labor force [in the 1980’s] than (few people省略)did [in the 1960’s and 1970’s], a twenty-year period during which people born after the war swelled the ranks of workers.
我认为错误的地方在than后面的括号中的注解，省略的应该是people，而不应该是few people，因为people自身这个名词是被作为被比较对象，在前后句子中充当主语，而并不是fewer/few people充当主语，所以省略的仅仅是people一个词
