premise: A man and a young girl swimming.
hypothesis: a father and daughter swim together
explanation_1: man and a young girl doesn't always mean father and daughter
explanation_2: A man and a girl may have different relationships other than father and daughter, (like uncle and niece, or brother and sister, etc.). Also they may not necessarily be swimming together, but separately.
explanation_3: Just because a man and a young girl swimming does not mean it is a father and daughter swim together.
