I was surprised Maldives or other island nations were not on the list...until I read the 'population exposed' on the columns. There not even close to 842 000 people in Maldives.
I agree - at Step 2 - Answers, you can click on a box at the right hand side Type-Ins and if you click that, the answers will be set up to accept a heap of alternative spellings like "UK". But it's an interesting quiz! Thanks for posting it.
Have you thought of doing a similar quiz of the percentage of each country's population exposed like this? Countries like Tuvalu have small populations, but could be potentially completely wiped out.
