premise: Three young adults pose for the camera.
hypothesis: Three people swim with dolphins.
explanation_1: You can't pose for the camera and swim at the same time. Posing means being still to get the shot, while swimming is active. Taking your eyes off of a dolphin when you're sharing space with it must not be advisable, either.
