premise: An old man holds up a sign.
hypothesis: A man is working.
explanation_1: Holding up a sign does not always imply working.
explanation_2: Are these the same men? Is the man holding a sign or working?
explanation_3: A MAN IN GENERAL CANNOT JUSTIFY AN OLD MAN AND WORKING IS NOT INDICATING HOLDING UP A SIGN
