The patch you're applying is intended for the original release of SoMI, which included this "history quiz" as a form of copy protection. You must be applying it to a later edition (Bounty Pack? Original budget re-release?), so this old copy protection is being re-enabled.
I believe the patch documentation states that these later editions don't need patching, as the bugs have been fixed anyway. Reinstalling the game should get it back to "normal", though if "normal" is "non-functional" I can't really help without more detail.
