premise: a young boy skateboarder jumping on a platform on a skateboard.
hypothesis: A boy is a very good skateboarder.
explanation_1: We do not know what the definition of very good is jumping on a platform. That could be a routine trick or just an accident. Maybe the boy didn't mean to jump onto the platform.
