premise: Arne Lie (September 25, 1921 – January 22, 1982) was a Norwegian actor best known for the voice of Paul Cox in the radio drama "God aften, mitt navn er Cox" (Good Evening, My Name is Cox), broadcast by the Norwegian Broadcasting Corporation's Radio Theater department, and for his role as Instructor Brandt in the Norwegian "Stompa" films and radio dramas, based on the Jennings novels.
hypothesis: The Norwegian Broadcasting Corporation did not exist in 1922.
reason: It's never stated in the text when it was first established, therefore we cannot definitively say the statement is either correct/incorrect and no hints are really given in the text. It's difficult perhaps because the year 1921 is similar to 1922, and this is enough to confuse the system.
