Since this is a well known "riddle" it is probably appropriate to assume the "standard conditions." If you wish to do "what-ifs" about other ways that the question could be posed, that's allright; but if you do that, then there's no real "answer" because someone else can always "repose" the question.

By all means, have fun with it.

Hilary - I think you've pretty much got it, but there's an extra "OTHER" that confuses me a little.

The "classic" problem is used to demonstrate the use of the boolian - "The AND of two inputs where one is TRUE and the other is FALSE is FALSE." Since you know that one of the answers will always be FALSE, you state a question that depends on BOTH answers, and then you know that the answer will be FALSE.
