premise: Three males and one female are posing for a photograph with snow on the ground and mountains covered with green trees and snow in the background.
hypothesis: Four friends pose for a photo on their ski holiday.
explanation_1: Posing together does not mean people are friends.  Snow on the ground and mountains does not mean people are on a ski holiday.
explanation_2: Just because four friends are posing for a photograph doesn't mean they are on their ski holiday.
explanation_3: They are not on a ski holiday and there are three male and one female in their group of friends.
