The good scholar's dilemma:
"The more you know, the more you don't know which right answer they want."
I run into this regularly with forms as well as polls. Questions that are ambiguous, or that can be taken several ways depneding on nuances of wording or assumptions.
What is really annoying is when such hesitation is put down to stupidity by people who can't even see the problem. (well, sometimes, when it is pointed out to them...)
