premise: A dog leaps into the air in a grassy field surrounded by trees.
hypothesis: A puppy jumps up to catch a ball.
explanation_1: Just because a dog leaps does not mean it is to catch a ball.
explanation_2: A dog can be of any age and doesn't have to be a puppy. Dogs don't leap into the air only when they want to catch a ball.
explanation_3: The dog could leap into the air for other reasons than to catch a ball.
