premise: An older food vendor, in a white embroidered shirt, maroon vest and checked apron, is sitting, leaning forward, with her elbows on her knees and her hands clasped, behind her foodstuffs. hypothesis: She is ready to sell more to the crowd.
contradiction: If she is sitting down with her elbows on her knees, behind her foodstuff, customers cannot see her so she cannot be ready to sell more to the crowd.
