premise: A man wearing a yellow shirt is riding a large riding lawn mower, which is spraying cut grass behind him; pine trees are visible in the background. hypothesis: The man does not live at the North Pole.
entailment: If the man is wearing a shirt without a jacket, riding a lawn mower, the mower is spraying cut grass, and there are pine trees visible, he does not live at the North Pole. If he lived at the North Pole, he would have on a coat, and would most likely not be riding a lawn mower. Even if he were, it would not be spraying cut grass, and there would not be pine trees visible.
