premise: A skier is upside down on skis with trees in the background.
hypothesis: A skier on a jump.
explanation_1: To say a skier is on a jump implies that they leapt off of a ski-jump ramp. This skier may have launched off of something less formal, like a mound of snow, or he could be falling off a cliff.
