premise: A young man waring black and carrying a skateboard looks at an outdoor skateboard park.
hypothesis: A girl with a ponytail is riding a bike at a park.
explanation_1: A young man and girl are clearly different.
explanation_2: A young man is not a girl. The man is wearing black while the girls wears a ponytail. The young man is carrying a skateboard but is not riding it. The girl, on the other hand, is riding her bike. The young man is at a skateboard park. The girl is at a park which is not necessarily a skateboard park.
explanation_3: There can either be a young man or a girl with a ponytail at the park. A young girl would not ride her bike at a skateboard park.
