Go to your RFP/Profile Outline view:
Once you are in the outline of an RFP or Profile that has not yet been published you can put your cursor over the question number to have a four-way arrow icon appear.
Once it does you can then drag-and-drop your question either up to the first spot or last spot in the Section or anywhere in-between.
And then there it is. The question has been moved!
If you happen to want to move a question from one section to another section, please check out this help article: How do I move a question from one section to another?
