A long time ago one of our colleagues was at a Quiz and a question was asked along the lines of "What is <city> famous for?"
No one in her team had a clue and so guessed something feasible. It turned out that no one had any idea what this place was famous for - quite sad really!
When it was discovered that no one had the correct answer, some wag opined that it couldn't be famous for whatever if no one knew about it!
And this raises an interesting point - if you ask what is anything famous for, surely (by definition) everyone should know the answer. So what's the point of asking the question.
Furthermore, what if somewhere is famous for a few things? Can you imagine asking "What is Paris famous for?" and the multitude of answers, all of which could be correct.
We suggest that you avoid such wording in your quiz questions.
