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 farmer is leading his horse carrying hay back to the barn.
explanation_1: You can stand by hay and not be a farmer. Just because the man is on a sled with a horse attached does not mean it is his horse.
explanation_2: He may not be a farmer.
explanation_3: Not all men are farmers.  Stading by a sled doesn't mean he is leading the horse, or that the horse belongs to him.  There is no indicating that they are going to a barn or where they are goin.
