Technically, there are only 9 provinces in North Korea. Pyongyang and Rason are included in the first-level administrative divisions, but as a direct-administered city and special city, respectively. If you include them, you should also include Nampo and Kaesong (special cities).
I have updated the quiz so Nampo and Kaesong are included. However the SVG map is still the same as before. I forgot how to make/edit SVG maps as I haven't worked on one in years
