premise: One man watching another man operate heavy machinery doing road construction.
hypothesis: Two workers are outside doing construction work.
explanation_1: Just because one man is watching another man operate heavy machinery doing road construction does not mean they are two workers.
explanation_2: The other man watching the man operate the machinery may not be doing work at all, therefore the two of them are not working.
explanation_3: Some roads are inside, not outside, in parking garages or in tunnels.
