Walking down a stairwell is different than someone who ran up and a place is darker if it has a shadow than brightly lighted.


Context: "A person in a dark outfit is walking down a stairwell which contains a shadow of an object." Claim: "The man ran up the stairs, all the while not knowing whom he was chasing, although floodlights brightly lighted the stairwell."
Considering the context, is the claim true, false, or unknown?
