no....the answer is unknown, haha...^_________^, ur answer is half right.. proof: 1.suppose the answer is not unknown... with common sense, we know that monk should be one of the answers. but unknown says he is a monk... so unknown should be one of the answer, which contradicts with the assumption... 2.suppose the answer is unknown... although he says he is a monk, but we still can c the hair on his head... then how can he do this... maybe only he knows... we don't know==>the answer is unknown, @_@,no contradiction.. done,^______________________________________________^!!!!!!!!!!!
