1. Can someone explain me the difference between "clue to determine" and "clue for determining" ??
I thought using "to V" format would be preferred than "for ~ ing" format.
2. Is it idiomatically incorrect to use 'to V' format after 'clue' ?
GMATNinjadaaghBoth seem fine to me. There's a subtle difference in meaning.
If Tim used clues
to determine which of his kids ate all his Pop-Tarts, "to determine" seems to describe the action "used." So Tim had a conscious plan to use the clues in a certain way.
But if Tim thought these clues would be great
for determining who ate his Pop-Tarts, "for determining" seems to describe
how the clues would be great. One set of clues might be great for figuring out who ate Tim's pancakes. Another set is good for figuring out who ate his Pop-Tarts.
Put another way: in the first example, there seems to be intent by whoever is using the clues. In the second example, we're describing the clues themselves.
Would I be comfortable using that as a decision point under pressure? Probably not. Fortunately, in this question there are plenty of other, better issues to use, such as logic and clarity. So if you find yourself wrestling with an idiom, stop and look for other decision points first. (More on idioms

I hope that helps!
