premise: A toddler wearing boots, a hat and an orange-sashed blue coat is looking behind him at a woman in a short-sleeved top, a skirt and platform heels as they walk along the street in the daytime. hypothesis: A toddler and a woman swimming in the ocean.
contradiction: The fact that they are swimming in the second sentence contradicts nearly every part of the prior statement unless they were shipwrecked and fell into the ocean in what sounds like spring clothing. But especially, walking is not swimming.
