Answer:Ok so I think I understand what its asking for here, first get a map pulled up that u can have to look at on the side to kind see where everything is, next you want to draw out the regions on the map that were affected by Christianity (and only those) then color them in. Once you have done that write the regions that were effected by Christianity on top of wherever you would typically find them on the map (so on top of where you drew your regions write what the regions name was on top of it). It's also saying that you can look up and research regions that were effected on the web.
Explanation: hope this helps!! :)
