premise: four kids are crossing a river by stepping stones
hypothesis: A group of kids are playing where they aren't supposed to.
explanation_1: Just because the kids are crossing a river doesn't imply that they are playing, they could just simply be crossing.  The fact that they are crossing a river does not indicate that they are where they aren't supposed to be.
