Passage Summary: Movie makers want their films in lots of theaters, and since theaters only pick movies that make money—especially from snacks—makers focus on what young people like.

Conclusion: Film producers aim to make movies that appeal to younger viewers to ensure wide distribution.

Reasoning: Theater managers only rent films they believe will be profitable (including snack sales), and producers want their films shown in as many theaters as possible.

Analysis: The argument jumps from 'theaters need profit' to 'producers target young people' without explaining the connection. The 'Necessary Assumption' must bridge this gap by suggesting that younger audiences are the ones who actually drive that profit, likely through those high-margin concession stands. If it weren't true that younger audiences are particularly profitable for theaters, the producers' strategy wouldn't make much sense. Look for an answer that links youth appeal to theater profitability.
