premise: Many people are sitting side by side on a low cement wall that separates a street from storefronts. hypothesis: A large group of people sitting side by side near a concrete wall across from a road that blocks the view of storefronts.
neutral: Sitting on a wall does not imply they are sitting near a wall.  A wall that separates a street from storefronts does not imply that it blocks the view of storefronts.
