premise: A blue light rail tram goes down a busy street while pedestrians wait to cross.
hypothesis: A blue tram goes down the street while pedestrians sight-see.
explanation_1: It cannot be assumed that the waiting pedestrians are there to sight-see.
explanation_2: Someone can sight-see without waiting to cross a street.
explanation_3: Just because a blue light rail tram goes down a busy street while pedestrians wait to cross does not mean the pedestrians sight-see.
