Leo: Premise: "Black and tan dog swimming toward shore of pond."
Hypothesis: "The dog nervously waiting in the waiting room of a vet's office."
Do we know that the hypothesis entailed by the premise?
Mei: OK, So, let's think first...
Me:
The dog can't be swimming in a pond and in the waiting room of a vets office at the same time.
Thus, the answer is no.
