premise: A black dog is drinking next to a brown and white dog that is looking at an orange ball in the lake, whilst a horse and rider passes behind.
hypothesis: Two dogs run together through a park, chasing toys as they are thrown.
explanation_1: Two dogs who run together can not be looking and drinking.
explanation_2: There can be either two or three dogs.
explanation_3: The dogs would not be drinking while they run. It would be hard to focus on looking at a ball in the lake while chasing toys.
