premise: A roofer in a gray sweatshirt and orange hat walks on a unfinished roof at a lake-side home.
hypothesis: The roofer is putting on shingles.
explanation_1: Being on a roof does not automatically imply that a roofer is putting on shingles.
explanation_2: The roofer could be putting something else on, not necessarily shingles.
explanation_3: just because he is a roofer doesn't mean he was putting on shingles.
