premise: An old man and lady in a white uniform is standing next to a man in black playing an instrument.
hypothesis: An old man and his nurse are listening to the musician play.
explanation_1: A lady in a white uniform is not necessarily a nurse.
explanation_2: Not all ladies are a nurse.  Standing beside the man playing doesn't mean they are listening to him.
explanation_3: An old man and lady in a white uniform  standing next to a man in black doesn't mean that lady in a white uniform is his nurse.
