There's something going wrong with this quiz. I'm also pretty certain some of the data is wrong. Try using this as a starting point: https://en.wikipedia.org/wiki/List_of_the_most_populous_counties_in_the_United_States
I also wouldn't require quiz takers to write "county". When I wrote Brooklyn, the whole quiz populated. Good luck.
