A man singled out as smiling can be clearly referred to as 'the' man; greeting is a likely thing for a smiling person to be doing, as smiling is a common component of greeting; men and women are people; since the other people 'walk past', nothing is stopping the man from also 'walking on by'.


Context: "A man wearing a black hat is smiling on a street as other men and woman walk past." Claim: "The man is greeting the people as he is walking on by."
Considering the context, is the claim true, false, or unknown?
