新prep221关于agreement， prohibit

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

B. prohibiting them from the disclosing of its water purification methods to any company

C. prohibiting disclosure of its water purification methods to any company

D. that would prohibit them from disclosure of its water purification methods to companies

E. that would prohibit its water purification methods to be disclosed to a company

A，prohibiting that不合法

B，them指代不清

C is the best，prohibit sth是ETS喜欢用法

 D、E，would虚拟时态不对

我的问题是：

The agreement 协议，是否应用一般现在时或过去现在时？

此加would 表虚拟？

请教牛牛

版主，能不能给出prohibit的所有主要用法？

还有，gwd上面讲的什么would表虚拟对不对阿？谢谢！

个人观点 请指正

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.  这些表示单复数的词一定要注意its, the company, each employee, a

A. prohibiting that its water purification methods be disclosed to companies 
            prohibit + that be done典型错误选项
        况且未划线部分是 using AN process 但是A选项却搭配的是companies

B. prohibiting them from the disclosing of its water purification methods to any company这里them指代错误 prohibit sb. from doing而不是from the doing

C. prohibiting disclosure of its water purification methods to any company正确 its还有any company与前面的单数遥相呼应
        非常好formal to make something impossible or prevent it from happening
        看来这个时候就是prohibit sth. 再补充一句有CDer说 prohibit sth.是GMAT偏好用法

D. that would prohibit them from disclosure of its water purification methods to companies如果是agreement这里最好还是用同位语从句而不是定语从句 them指代错误
        后面companies与using an analogous purification process不符合
        虚拟语气用的不好

E. that would prohibit its water purification methods to be disclosed to a company

同样用定语从句用的不好
        虚拟语气用的不好
            

ls mm说得很好了。

情态动词不能乱加减。

说明agreement的内容应该用定语从句比较好吧？

哪位高人来指点下，我主要是疑惑E
