premise: A man with a cap and brown shirt is standing on a grassy incline by a pile of hay or grass on some kind of wooden sled attached to a horse with chains.
hypothesis: A man is outside next to a sled filled with hay pulled by a horse.
explanation_1: A man attached to a horse with chains implies he's being pulled by the horse.
explanation_2: If the sled has a horse with chains, it can be assumed that the sled is pulled by the horse.
explanation_3: The man is on a grassy incline, so he is outside. The sled is pulled by the horse it is attached to with chains.
