premise: A young girl in a helmet walks barefoot across a mossy tree trunk that is lying over water.
hypothesis: A girl is playing on a tree.
explanation_1: She may be passing through the trunks, not playing.
explanation_2: Someone may be walking on a tree trunk without playing. They could be trying to cross for many reasons.
explanation_3: Just because the girl is walking doesn't mean she is playing on the tree.
