premise: A man in green and a woman in a gray sweater are looking at some unidentified object.
hypothesis: A man and a woman are looking at the sky.
explanation_1: Sentence two did not state what color shirts the people were wearing and because they are looking at an identified object doesn't mean they are looking at the sky.
