premise: A man is running down a sand covered mountain.
hypothesis: A man tumbling down a snowy hill.
explanation_1: A person who is running on a sand covered mountain is on his feet, moving with purpose and on different terrain at a higher elevation than someone tumbling down a snowy hill as that person is not on their feet and likely not moving with purpose, as well as being on colder ground at a lower elevation.
