Leo: Premise: "A placard on a brick wall is displaying an advertisement for flan and a man at the corner of the building is talking on a cellphone."
Hypothesis: "A man asks his wife what she wants from takeout."
Do we know that the hypothesis entailed by the premise?
Mei: OK, So, let's think first...
Me:
The man talking on a cellphone is not necessarily talking to his wife.
Thus, the answer is it is not possible to tell.
