premise: A boy speeding down a steep slide.
hypothesis: A boy swinging in the air
explanation_1: Speeding down a slide can't be done while in the air, because being in the air would mean you aren't touching the slide. Also swinging can't be done while sliding down a slide, they're two different objects.
