premise: 2 Older women and a young girl with a red bike. hypothesis: Two mothers watch the child ride her bike down the hill.
neutral: Just because there are two older women with a young girl does not mean these women are mothers. Also no evidence the young girl is even riding the red bike. She could be standing next to it. And you can not assume the child ride her bike down a hill. If she is standing next to the bike, she can't ride it down the hill.
