premise: Two women wearing black t-shirts are sitting in the grass.
hypothesis: 2 women chat together on the grass at a park
explanation_1: Just because they are sitting does not mean they are chatting together. It also does not infer that they are at a park just because they are on grass.
explanation_2: Two women may or may not be at a park, and indeed may not chat together.
explanation_3: The two women in the grass may not be having a chat together, and they may not specifically be in a park.
