premise: A young boy plays in the sprinklers, allowing the water to spray completely over his right arm.
hypothesis: The boy is wearing yellow swimming trunks.
explanation_1: The boy can be wearing anything, playing in a sprinkler doesn't require swim trunks.
explanation_2: It is unknowable if the boy is wearing swim trunks.
explanation_3: Just because a young boy plays in the sprinklers, allowing the water to spray completely over his right arm, doesn't mean he is wearing yellow swimming trunks.
