premise: A blond-haired woman and her friend are buying some items from the man in the white t-shirt while the other blond woman stands near the baby stroller. hypothesis: A woman sells something to the woman with the stroller.
contradiction: If someone is buying items from a man, then it cannot be claimed that a woman is doing the selling. If a blond woman just stands near a stroller and is not buying items, then it can't be claimed that something is being sold to the woman.
