premise: The tops of a large number of balloons are visible behind a wall, with a large high rise building in the background.
hypothesis: A bunch of balloons can be seen as people wait for a surprise party to start.
explanation_1: Just because a large number of balloons are visible doesn't mean they are being seen by people who happen to be waiting for a surprise party.
explanation_2: In fact that a large number of balloons does not imply there is a surprise party.
explanation_3: Just because a bunch of balloons does not mean it is for a surprise party.
