Leo: Premise: "A girl with arms raised in sliding down a red and white slide."
Hypothesis: "The excited girl slid down the slide for her mom to see."
Do we know that the hypothesis entailed by the premise?
Mei: OK, So, let's think first...
Me:
A girl sliding down a slide does not imply it is for her mom to see or that the girl is excited.
Thus, the answer is it is not possible to tell.
