On a certain island, the inhabitants are divided into two types, those who always tell the truth and those who always lie. One day a vistor to the island stops three inhabitants of the island to ask for directions to a well known museum. "All three of us are liars," warns the first inhabitant, "not so, only two of us are liars," says the second. "Not so," says the third, "The other two guys are lying." Which, if any, of the three islanders can the visitor truth to give honest directions? The second, right?
