The 47th annual Berlin International Film Festival was held from February 13 to 24, 1997. The Golden Bear was awarded to Canadian-American film "The People vs. Larry Flynt" directed by Miloš Forman. The retrospective dedicated to Austrian film director G. W. Pabst was shown at the festival. Using only the above description and what you know about the world, "The 47th annual Berlin International Film Festival was at least twelve days." is definitely correct, incorrect, or inconclusive?
