Hi, KimFergus --
I think these are your options:
- use the instructions at the top of the page
-- to keep the instructions on hand for students to refer back to, either keep the questions all on one page or allow backtracking.
- use the stimulus (or the rce for a question) to add the text/example (or image, slide deck, video, link, etc.) and attach the questions that go with that text
Since it is a quiz, the text must be relevant to a question or set of questions. Otherwise, what would be the purpose of it in the quiz? Can you give an example of when you would add text not relevant to the questions in the quiz?
