I like the quiz, but you have some errors: Burkinabé is the name for people from Burkina Faso. Ivoirian is another common way to spell Ivorian, per Wikipedia. Ecuadorian is spelled wrong. Salvadoran is spelled wrong. Guinean is spelled wrong for Guinea but right for Guinea-Bissau. Basotho didn't seem to work, even though it appears correctly after you finish the quiz. Montenegrin is spelled wrong. Vincentian is spelled wrong. Sierra Leonean is spelled wrong.
