Ken, and Mark are, not necessarily in this order, a quarterback, a
receiver, and a kicker. The kicker, who is the shortest of the three, is
a bachelor. Bill, who is Ken's father-in-law, is taller than the
receiver.Who plays in which position?
Bill is Ken's father-in-law, both Bill and Ken must be married. This
leaves the only remaining person, Mark, to be the bachelor (and hence
the kicker). Since Bill is taller than the receiver, Bill must not be
the receiver. By process of elimination, we conclude that Bill is the
quarterback. The remaining position (the receiver) goes to Ken.Therefore, Bill is the quarterback, Ken is the receiver, and Mark is the kicker.
