[求助]请教OG11 SC中的几题

OG11的第11题~

Warning that computers in the US are not secure , the National Academy of Sciences has urged the nation to revamp computer security procedures, institue new emergency response teams,creating a special nongovernment organization to take charge of computer security planning,

D)and create a special nongovernment organization for taking

E)and create a special nongovernment organization to take 

向导中说是选E，说to take 是表“目的”，这个我也知道，不过我记得for也有表示“目的”的意思。我不知道为什么要选to take ~麻烦大家指导一下。

By the way, 我想问问"as to" ，"as for " 和"as regard"有没区别

我刚刚准备G，语法还比较差，还请大家多多关照~~谢啦~
