premise: The boy in swim trunks is laying face down on a watery pavement. hypothesis: The boy has just been pulled out of the swimming pool, and lifeguards are about to start giving him CPR.
neutral: Just because the boy in swim trunks is laying face down on a watery pavement it doesn't mean the boy had just been pulled out of the swimming pool and lifeguards are about to start giving him CPR. This boy may have tripped on a watery patch of pavement and fallen on his face.
