You hold the rights to a 15-minute celebrity interview. You’re fine if fans upload a clip, provided that their video also contains other content longer than your clip. What custom policy would achieve this goal?

The correct policy, "Block if user video match amount 50%, Monetize if user video match amount <50%," achieves the goal because it allows monetization (and thus the upload) of videos where the matched content (your interview clip) is less than 50% of the user's total video. This means the user's video must contain more original content than your clip to be monetized. The other options are incorrect because they either block videos with less than 50% matched content (e.g., "90%," "10%") or only block at an exact 50% match, which doesn't allow for the desired monetization of videos with substantial original content.
