premise: A black dog is in midair as a woman behind it cheers. hypothesis: A dog competing in an event jumps to catch a ball as her owner cheers the dog on.
neutral: The dog is in midair but that doesn't necessarily mean the dog is competing in an event. The dog may or may not be jumping to catch a ball. The dog could be a he and not a she. The woman behind the dog isn't necessarily the dogs owner.
