The prompt for "countries that border Indonesia" looks wrong, but it's not. Did you read the top of the column? The full prompt is "Countries that border countries that border Indonesia."
I think you should also include a note that for historical borders you are looking for the historical countries, and not what they would border in the modern day. Great quiz though!
