Passage Summary: Music companies only put old music on CDs if they think it will make money. Since classic jazz isn't played much on the radio, the author thinks most of it won't be turned into CDs.

Conclusion: The majority of classic jazz recordings will likely never be released on compact disc.

Reasoning: Record labels only transfer recordings they expect to be profitable, and very few classic jazz recordings receive radio airplay.

Analysis: This argument has a significant logical gap between radio airplay and profitability. To make this conclusion follow logically, we need to bridge that gap by assuming that radio play is a necessary condition for a recording to be considered profitable. Look for an answer choice that guarantees that if a recording isn't played on the radio, the record company won't believe it can sell well enough to be profitable. Without this link, it is possible that jazz could be profitable through other avenues, like niche collectors or word-of-mouth.
