premise: A man in a pink robe gets his hair trimmed. hypothesis: A man is getting his hair trimmed.
entailment: describing a picture of man who gets his hair trimmed can also be described as seeing a man who is getting his hair trimmed in the picture because what is in a photograph seems frozen in time and a man who gets his hair trimmed in a picture is always getting his hair trimmed; the man will never get up out of the chair in the picture and be finished.
