premise: A brown dog in running on grass.
hypothesis: A dog is playing at the park
explanation_1: We do not know if the dog is playing. Perhaps it has escaped its yard and is lost.
explanation_2: Grass does not only appear at the park.
explanation_3: Just because a dog is running in the grass it does not mean they are at the park playing.
