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.

1. prohibiting that its water purification methods be disclosed to companies
2. prohibiting them from the disclosing of its water purification methods to any company
3. prohibiting disclosure of its water purification methods to any company
4. that would prohibit them from disclosure of its water purification methods to companies
5. that would prohibit its water purification methods to be disclosed to a company

这题答案给的是E，小妹我选的是B，感觉E中prohibit的用法不太对，prohibit应该和stop,prevent一样都是stop... from doing，而不是to do结构。而且E太罗嗦，不如C简洁。C中的any company的语气比E更强，强调了不能泄露给任何一家的相似的公司。

不知为个哥哥姐姐有什么看法？

我想C & E 的争议点在于E比较简洁但却用错idiom (prohibited to是错的, 正确是prohibited from).

C虽然用了正确的idiom, 但却罗唆(记得哪位NN说过gmat中用动词表达通常最简洁)
