premise: Three girls are looking over the side of a stone railing at a river in front of them. hypothesis: Three school children are watching the river from the bridge.
neutral: We cannot assume that the girls are necessarily children as many people refer to females of any age as girls. Further, there is no evidence that the girls are in school. Finally, we cannot know that they are on a bridge. While they are looking over a stone railing, they may be on a patio or in a park.
