In this Double Generator quiz, find two geographical locations. The 12-letter location is made from the 12 purple letters on the outside edge of the 4 x 4 grid; and the 8-letter location is comprised of the letters in the 8 green shaded squares. There are also the usual 20 questions, whose answers are drawn from all of the letters in the 4 x 4 grid. Each letter can only be used once.
Interesting - we'd always assumed "Latin America" to be every country south of the US, rather than the countries where Spanish/Portuguese/French is spoken! (and some definitions do take our approach). We've dropped the "Latin" from the clue to be unambiguous.
