Leo: Premise: "Two men wearing santa claus costumes are dancing while people watch."
Hypothesis: "Two old men wearing santa claus costumes are tango dancing while people watch."
Do we know that the hypothesis entailed by the premise?
Mei: OK, So, let's think first...
Me:
The men might not be old and they might not be tango dancing.
Thus, the answer is it is not possible to tell.
