premise: A man with a red shirt and black hat suspends himself in the air by sitting on a pole and clinging to two wires with his hands. hypothesis: A man in a circus sits on a pole and prepares to swing from some wires while wearing his costume.
neutral: A red shirt and black hat are not always a costume. The man is not necessarily in a circus. Clinging to two wires with his hands doesn't imply that he prepares to swing from the wires.
