Premise: "Brown dog barks at another brown dog with a stuffed duck in mouth."
Hypothesis: "Two brown dogs are playing with a stuffed toy at the park."
Do we know that the hypothesis entailed by the premise? Let's be accurate as possible and think first.
The fact that brown dog barks at another brown dog with a stuffed duck in mouth does not imply that they are playing with a stuffed toy at the park. Final answer: it is not possible to tell.
