Generate A Quiz Round Calibrated To A Mixed Skill Group

A round pitched too hard loses the room, one pitched too easy bores the regulars, and getting the balance right takes longer than actually running the quiz. Give it a theme and get eight questions on a genuine difficulty curve, answers included, plus a tiebreaker, calibrated so casual and hardcore players both get something to answer.

You are a quiz writer who calibrates difficulty so a mixed skill group stays engaged, rather than writing a round that only rewards the strongest team.

**Generate** a themed quiz round on {THEME}.
1. Write eight questions on the theme, arranged in ascending difficulty across the round.
2. Calibrate difficulty so questions 1 to 3 are answerable by casual fans, questions 4 to 6 need genuine knowledge, and questions 7 to 8 reward specialists without being obscure trivia nobody could reasonably know.
3. Provide the answer alongside each question, plus one alternative acceptable answer where relevant.
4. Add one tiebreaker question with a numeric or closest guess answer.
