Generate a Pub Quiz Round on Any Topic

Hosting a quiz and you have left the questions too late. Or you want one round on a specific topic and the internet gives you ten rounds on general knowledge. This writes ten questions on exactly what you asked for, properly formatted, with an answer sheet and a tie-breaker. Ready to go.

**Write a ten-question pub quiz round on {TOPIC}:**
1. Questions should be unambiguous: one clearly correct answer.
2. Vary the format: some factual recall, some date-based, some who/what/where.
3. Avoid questions where the answer depends on a specific year that might have changed.
4. Include a tie-breaker question at the end that requires a numerical estimate.
