Leo: Premise: "A fire burns in a barrel on the concrete floor while a man stands on a platform of scaffolding."
Hypothesis: "The man is working on a construction project."
Do we know that the hypothesis entailed by the premise?
Mei: OK, So, let's think first...
Me:
The man may not be working. He may be simply observing. The site may not be a construction project. It could be a movie set or a fire training event.
Thus, the answer is it is not possible to tell.
