Here's a better source: https://volcano.si.edu/volcanolist_countries.cfm
These countries are missing from the quiz: Armenia, Australia, Azerbaijan, Myanmar, Georgia, Honduras, (India's are in the Andaman Islands), Jordan, Mongolia, (Sint Eustatius & Saba in the Netherlands), Niger, (Norwegian Jan Mayen & Bouvet), Syria, Uganda, (UK's territories), Vietnam.
These countries are in the quiz but not the list: Afghanistan (all of them are of Pleistocene age), Pakistan (Tor Zawar is not a true volcano), Malaysia (all the volcanoes on the wiki are either mud volcanoes or part of the late Pleistocene Tawau Hills volcanic field), North Macedonia, Libya (I don't know why, Wau-en-Namus is a thing).
