premise: Two men dressed in black practicing martial arts on a gym floor.
hypothesis: Two men are training in jeet kun do on the gym floor.

explanation_2: There are other forms of martial arts, so jeet kun do isn't necessarily the form of martial arts that the men were practicing.
explanation_3: Just because two men dressed in black practicing martial arts on a gym floor, doesn't mean they are training in jeet kun.
