Thanks Shraddha
egmat. It didn't occur to me that
for taking charge describes the action
to create and not the noun
organization. It does make sense if I think about it, but how could you tell?
How about this sentence: "Astronomers have developed a scale for rating the likelihood that a particular asteroid or comet will collide with Earth." Can I say to rate, since it'll describe that scale?
Thanrks Shraddha!

Hello
shabuzen102,
The context of the sentence tells us what a modifier is meant to modify. This is how I analyzed the sentence. The NAS asked the US
to create a special nongovernment organization. If we add
for taking charge... after this phrase, it modifies the action
to create. Now, who is the doer of the action denoted by
to create? So, per this modification, the US must create a special nongovernment organization so that the US can take charge of computer security planning. But this meaning does not fit into the context of the sentence. Why?
Firstly, because if the US has to take charge of the security planning, then what is the need for a separate nongovernment organization?
Secondly, this new organization is supposed to be a "nongovernment" entity. If the administrators of the country are to run this organization, then how can it be a nongovernment organization?
Hence, the conclusion that the sentence must use
to take charge to refer to the noun a nongovernment organization and not
for taking charge that modifies the action
to create.
Now, let's talk about the other official sentence.
Astronomers have developed a scale for rating the likelihood that a particular asteroid or comet will collide with Earth. In this sentence, the use
for rating is correct as it correctly modifies the action
have developed. The astronomers have developed a scale so that they can rate the likelihood of a particular event. Please note that the scale does not rate the likelihood. It probably will give some numbers or statistics. But teh astronomers will do the rating. Hence, the use of for rating is correct.
Hope this helps.

Thanks.
Shraddha
