#3, RE: question you can't answer

The problem is not stated precisely, but the answer should be yes/no only. It would be better to ask if the following statement is true or false:

This statement is false.

The statement is self negating, it can not be either true or false. That is basically the same paradox as the question, "is no your answer to this question."
