Passage Summary: A certain film festival only shows Canadian movies, and most of the movies that won awards there also won awards at other festivals around the world.

Reasoning: The festival only shows Canadian films, and most of the films that won prizes there also won prizes at international festivals.

Analysis: Since this is a 'Must Be True' question, we need to find a valid inference by combining the provided facts. We know two things: 1) Every film at this festival is Canadian, and 2) Most of the prize-winning films at this festival won international prizes. By combining these, we can conclude that at least some Canadian films (specifically, those prize winners) have won prizes at international festivals. Show how the overlap between the 'Canadian-only' rule and the 'international winner' fact leads to a guaranteed statement about Canadian films.
