Just because the worker is holding a broom one can't imply he is sweeping. Also just because the worker is standing on concrete it doesn't necessarily imply it is a sidewalk.


Context: "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." Claim: "A worker is sweeping the sidewalk."
Considering the context, is the claim true, false, or unknown?
