Who should be given priority?

I would agree that we should include a "Prefer not to say" option, but I'm not convinced on the "I don't know" option. Should we really have 2 null options for this question? What do you think of changing "I don't know" to "No group should be given priority" as a different option?

If we go with the question posed by Wendy, and people choose the "Other reasons" option, will there be a follow up question? I believe Prof. Owen said a follow up question will count as one of our 5 questions. I think a follow up be might a waste when there are so many other great questions we could ask.
