Final answer:
Genres stabilize the film industry by providing familiar storytelling elements to audiences.
Step-by-step explanation:
Genres serve to stabilize an otherwise unstable film industry by providing audiences with familiar and predictable storytelling elements. By categorizing movies into genres such as comedy, horror, drama, and science fiction, filmmakers can target specific audience preferences and increase the chances of success. For example, if a movie falls into the comedy genre, audiences will expect to laugh and be entertained by humorous situations and dialogue.
