premise: Man jumping over a rusty fence on a blue bicycle.
hypothesis: Man jumping over the fence on his bicycle trying to escape from the dog.
explanation_1: Just because the man is jumping over a fence doesn't mean he's trying to escape from a dog.
explanation_2: He may be on a trick rather than an escape from dog
explanation_3: The first sentence doesn't say that he's trying to escape from a dog.
