premise: A young man shielding himself from a stream of water from a fire engine by using an umbrella.
hypothesis: A young man gets hit in the face with a frisbee.
explanation_1: The man is either shielding himself or gets hit in the face, and what's coming at him is either a stream of water or a frisbee. Also, an umbrella will not be a useful shield for water coming from a fire engine.
explanation_2: A frisbee is not a stream of water.
explanation_3: GETS HIT IS CONTRADICTORY TO SHIELDING AND DEFENDING HIMSELF
