Write a Pub Quiz Round on Any Subject

You are running a quiz night and you need a round on something specific and you are running out of time. Name the subject and the difficulty and this writes ten questions with clean wording, one correct answer each, and a bonus question worth two points. The answer sheet notes where a valid alternative should be accepted.

**Write a pub quiz round:**
1. Write {QUESTION_COUNT} questions on the subject, varying the format: some factual, some fill-in-the-blank, one picture-round description if appropriate.
2. Make each question unambiguous: one correct answer, no trick wording.
3. Match difficulty to the stated level.
4. Provide the answer sheet with a note for any question that might attract a valid alternative answer.
