Leo: Premise: "The three firemen are talking near the two red firetrucks."
Hypothesis: "Three firemen decide the best way to put out the roaring fire behind their trucks."
Do we know that the hypothesis entailed by the premise?
Mei: OK, So, let's think first...
Me:
Three fireman talking does not imply they decide the best way to put out the fire.
Thus, the answer is it is not possible to tell.
