There are two kinds of people living on the island of liars and honest people: liars and honest people. Liars never tell the truth - they always lie. The honest always tell the truth - they never lie. We have two brothers: Adam and Peter, whom we know are either both liars or both honest. Someone asked them both if they were married. They replied as follows: Adam: "We're both married." Peter: "I'm not married." Is Adam married? Is Peter married? (Justify your answers.)
