premise: Ben Barzman (October 12, 1910 – December 15, 1989) was a Canadian journalist, screenwriter, and novelist, blacklisted during the McCarthy Era and best known for his screenplays for the films "Back to Bataan" (1945), "El Cid" (1961), and "The Blue Max" (1966).
hypothesis: Ben Barzman was writing screenplays when Harry Truman was president of the US
reason: My statement is definitely correct because it stated he wrote Back to Bataan in 1945, and Harry S. Truman was US president in 1945. Maybe the system cannot determine what else what happening in the world in the same year
