premise: A man in orange and white rides his mountain bike through a forest.
hypothesis: The man is riding a 12-speed bike and wearing orange shirt and white shorts.
explanation_1: Not all bikes are 12-speed and just because he's wearing orange and white doesn't mean those colors are on his shorts.
explanation_2: We have no idea he is riding a 12-speed bike, he could be riding any style bike.
explanation_3: Just because a man in orange and white rides his mountain bike through a forest, it doesn't mean this man is riding a 12-speed bike. It also doesn't mean his shirt is orange and his shorts are white.
