premise: Skiiers at the top of a snow covered hill.
hypothesis: The men are going snowshoeing.
explanation_1: Skiiers who are at the top and ready to ski on two boards attached to their feet whereas people who are going snowshoeing may be anywhere in the process of going and might not be ready at all, and snowshoes are an entirely different type of equipment than skis.
