2 Guests must A have previous acting experience. B learn lighting techniques. C choose a job to do. D have previous experience in filmmaking.

The correct answer is **C choose a job to do.** **Explanation:** The text states "Our holidays are aimed at beginners who want to learn about filmmaking. Our guests come together to make a short film over a period of two weeks. Guests choose what position in the film production team they are interested in." This indicates that guests choose a role within the film production, which aligns with choosing a job to do.
