Got confused by the (United States - Alaska) part and so didn't put the US because I thought it had already been given. I spent the last minute or so trying to figure out what on earth was higher than mexico but lower than Canada. Tried typing in every other North/South America thinking there was one with some random island in the pacific.
It took me longer to type “El Salvador” correctly than the entire quiz (excluding the time it took for me to think of Nicaragua) because i kept typing “El Sal,ador”
