premise: A group of people hold hands on the beach. hypothesis: A family takes in the ocean air as they hold hands walking along the ocean shore.
neutral: The fact that the people are a family cannot be inferred from the description 'group of people' because a group of people can have any type of relationship.  The fact that they are holding hands does not infer any type of motion, walking or otherwise on the part of the people.  They could easily be holding hands and standing still.
