premise: A fireman with a neon helmet and a pickaxe inspects some debris with a flashlight.
hypothesis: A fireman sits at his station.
explanation_1: The fireman cannot be inspecting debris while he sits at his station.
explanation_2: A fireman can not be inspecting debris while sitting at his station.
explanation_3: A fireman with a neon helmet and a pickaxe inspects some debris with a flashlight implies he is at a fire or somewhere that needs inspection. A fireman who sits at a station does not necessarily mean that he couldn't be with a neon helmet and have equipment, but if he is at a site doing inspection, then he would not be at his station. Also, a fireman could be sitting at his station, in garb and with equipment inspecting debris with a flashlight all at the same time. Since there is no location where he is doing the inspection I cannot see a contradiction.
