Why are there only 422 answers when there are 433 units?
I excluded certain units on purpose, as they are designations containing other units (eg. National Mall and Memorial Parks, which covers many of the DC units). I also combined several units that are both National Parks and National Preserves, which is why you will sometimes see the abbreviation NP&Pres.

Miscellaneous Notes
I spent quite a while on this quiz and did everything to the best of my ability. However, there may still be errors in they type-ins, names, or designations of certain units. Feel free to let me know about any errors in the quiz comments and I will fix it ASAP. Suggestions for improving the quiz are also welcome. I will also update the quiz as necessary.
