premise: A group of men and women in swimwear sit on a beach in yoga poses. hypothesis: A group of fat men and women in swimwear sit on a beach in yoga poses.
neutral: Since they are doing yoga poses as a group it must be a class or gathering of men and women. It cannot be infered if they are indeed actually fat because men and women have vastly different body structures so it cannot be proven whether they are men, women, etc.
