Leo: Premise: "A large white puddle running along with a pink flip-flop in its mouth."
Hypothesis: "A dog is being chases by someone."
Do we know that the hypothesis entailed by the premise?
Mei: OK, So, let's think first...
Me:
Just because puddle running with a flip-flop in mouth doesn't imply being chases by someone.
Thus, the answer is it is not possible to tell.
