The rubric refers to the old textbook's chapter 24 for the three cultural regions of Louisiana. Your new book gives five cultural regions. For the sake of simplicity I recommend that you use the regions on this map:

However, you may use the five regions from the new book and the overhead if you prefer.
Thanks to the student who spotted this, he gets 5 bonus points.
