premise: A father and son kicking a ball at a park.
hypothesis: The mother taught her cousin how to hit the ball.
explanation_1: A father and son is a different relationship than a mother and her cousin. The action (and most likely the sport) has changed from kicking to hitting a ball.
explanation_2: A father is male a mother is female. A cousin is an uncle or aunts child, while a son is that persons child. Kicking a ball is done with a foot, hitting a ball is done with a bat.
explanation_3: There can be either a father and son or a mother and cousin.
