premise: A child slides into a wading pool full of water while an adult tosses a bucket of water on them.
hypothesis: A father and son are playing at a waterpark.
explanation_1: Child and adult does not imply father and son.  A wading pool does not imply a waterpark.
explanation_2: just because the child is playing with water means he is in a waterpark.
explanation_3: Sentence 1 doesn't say that the scene takes place at a waterpark.
