premise: The dark-haired woman puts her leg up on a padded stool as she helps the other woman put on her necklace. hypothesis: A woman working in a jewelry store with a sprained ankle, rests it on a stool as she help a customer try on a necklace.
neutral: Putting her leg on a stool does not necessarily mean she has a sprained ankle.  Helping a woman with a necklace does not necessarily imply that one woman is helping a customer while working in a jewelry store.
