premise: A lady is sitting on a bench wearing sunglasses and holding a walking cane. hypothesis: The photograph only shows a man holding a basketball.
contradiction: A lady is not a man. Furthermore, people do not tend to have more than one hand occupied, unless they are on the same action or item. Although possible, it is unlikely for someone holding a walking cane to also be holding a basketball. Where s(he) is sitting on a bench, it would be much more practical to set one or the other down. If a person needs a cane for walking, they are unlikely to shoot a basketball, which requires standing while using both hands, so the basketball would likely be held for someone else, decreasing the probability of either the walking cane or the basketball being held.
