premise: A large competition sailboat is surrounded by three small boats in the middle of the water.
hypothesis: A large boat with a green flag on the back is towering above three smaller boats with the same flag.
explanation_1: Boats can fly flags of many kinds, and there is no reason for them to share the same flag or for one of them to have a green flag on the back. Just because a large sailboat is surrounded by small boats doesn't mean that the large boat is towering over the small boats.
explanation_2: Not all boats necessarily have the same flag.
explanation_3: We do not know the colors or locations of a flag on competition sailboats.
