premise: Two older men speak into microphones on a stage, while a projector screen displays a vintage photo of a young man behind them.
hypothesis: Two men in black suits are addressing a crowd of people seated in front of them.
explanation_1: Men are not assumed to be wearing black suits.  Being on stage does not imply that there is a crowd of people seated in front of them.
explanation_2: Not all men in black suits are older men. Not all men speaking into a microphone are addressing a crowd.
explanation_3: Two men speak into microphones on a stage don't necessarily imply that the two men are in black suits and are addressing a crowd of people seated in front of them.
