Shouldn’t this quiz have every single country in the world on it? Humans are primates, after all, and I know of no countries with a human population of 0!
A minor quibble - if you're counting introduced, Florida (USA) has six locations with four total species of monkeys in the wild - Rhesus, Vervet, Squirrel, and Crab-eating Macaques.
Gibraltar's somewhat famous for being the only place in Europe that has monkeys. As for the other two I'd never heard of them having monkeys but they both seem like fairly likely places to find them.
