What I was trying to point out is that this riddle is poorly done.
Do you truly believe the answer given by the person who created it has to be correct just because he created it?

"no" isn't the answer... in both cases (and there are no other cases, at least using traditional logic) explained above by me, "no" cannot be the answer. In one of the cases it creates a paradox, in the other case the answer to the riddle isn't the answer to the last question, so "no" is not the answer anyway...
