premise: There is a woman in a black jacket and sunglasses and a man in a white shirt with his back turned. hypothesis: A couple stands in a street during the day.
neutral: One cannot infer that the man and woman are a couple just because they are near each other. There is no way to infer that they are in the street, because their location is not mentioned. It is impossible to infer the time of day even if the man is wearing sunglasses. It could be a fashion statement and not the need to keep the sun out of his eyes.
