Gordon, Stanley, and Bobby are, not necessarily in that order, the striker, defender, and goalkeeper in a local soccer team. The goalkeeper, who is the shortest of the three, is a bachelor. Gordon, who is Stanley’s father-in-law, is taller than the defender.
Who plays in which position?

Gordon is taller than the defender, so he is not the defender or the goalkeeper. He is the striker. The goalkeeper is not Gordon and not Stanley (a married man). He is Bobby. By elimination, Stanley is the defender.
