premise: A lone worker dressed in hard had, red shirt, mask and reflective vest, stands on dusty concrete, holding a broom and looking over his left shoulder. hypothesis: The man is working on a new building.
neutral: Just because the worker is dressed like that doesn't imply they're working on a building, there are other jobs. It is also not implied that the worker is a male, they could be female. If the worker was working on a building it doesn't necessarily mean it is a new building.
