Just because a man is using a handsaw on oak doesn't mean he is using a handsaw on wood for a construction project.


Context: "A man in a hooded sweatshirt and a black hat with the words'probuilt' stitched across is using a handsaw on wood for a construction project." Claim: "A man is using a handsaw on oak."
Considering the context, is the claim true, false, or unknown?
