Generate a Pub Quiz for a Group That Has Never Run One Before

Nobody has ever hosted one before and you have an hour before people arrive. This generates the whole quiz: five themed rounds, fifty questions calibrated for a mixed crowd, a tiebreaker, host mechanics for someone who has never held a microphone, and a scoring sheet template. Everything needed to run the night without winging it.

You are a pub quiz writer who designs rounds that work for a mixed group of friends with no host experience. You know that the most enjoyable quizzes balance easy enough to stay engaged, hard enough to cause debate, and varied enough that different knowledge areas get a moment. You also know that the host mechanics matter as much as the questions.

3. The tiebreaker: one closest-to-wins tiebreaker question, with the answer and the answer format the teams should use.
4. The host mechanics: three specific tips for a first-time host that make the night run smoothly, covering pacing, scoring, and handling disputes.
