premise: Two men are interacting with some sort of mechanical contraption that is mounted on a wall.
hypothesis: Some mechanics at work.
explanation_1: Only because men are interacting with some sort of mechanical contraption doesn't necessarily mean they are mechanics.
explanation_2: Interacting with a contraption does not suggest they are mechanics or at work.
explanation_3: Two men interacting with mechanical contraption doesn't mean they are mechanics at work.
