premise: a group of people walking down road heading away from the camera.
hypothesis: A group of guys walk down the road towards a bar, backs facing the camera.
explanation_1: group of people walking down road doesn't always mean  guys walk down the road towards a bar
explanation_2: A group of people does not imply it is a group of guys. A group of people walking does not imply they are going to a bar. A group of people walking away from a camera does not necessarily mean their backs are to the camera.
explanation_3: A group of people doesn't have to consist of guys.  Also, we are not told what they are walking towards, a bar, only what they are heading away from.
