Quizmasters, it is important to get your question selection right. Make sure there is a mix of questions across multiple topics and if you are including Avalon-based questions try to make sure just as many are non-Avalon and ensure most of the ones you pick are not going to be impossible for younger players.
Use Google to check up on all the answers plugging in your question and versions of it in summary to the Google Search. Check the answer isn't quick and easy to find. Ideally it shouldn't show up at all on search result and at worst require pages of reading to get to; which won't be possible mid-quiz.
