premise: An artist dressed in a gray sweatshirt is working on a brightly colored painting of a town.
hypothesis: A painter is wearing a dark colored apron with a brush in her right hand.
explanation_1: A sweatshirt can be something other than an apron, and being gray does not imply that it is dark colored. An artist working on a painting does not imply that there is a brush in her right hand. An artist can be something other than female.
explanation_2: Just because the artist is working on a painting doesn't mean the artist is wearing an apron or using a brush.
explanation_3: Gray sweatshirt is not the same as dark colored apron.  Not all artists are women, right-handed, or paint with brushes, so the phrase "brush in her right hand" is unjustified.
