Leo: Premise: "A dog in the water while three individuals walk across a rocky footbridge."
Hypothesis: "Someone from the group threw a stick into the water and the dog is chasing it."
Do we know that the hypothesis entailed by the premise?
Mei: OK, So, let's think first...
Me:
One of the individuals would not have necessarily thrown a stick. The dog would not necessarily be chasing a stick.
Thus, the answer is it is not possible to tell.
