1) Change Macedonia to North Macedonia.
2) Change Swaziland to Eswatini (which will result in this being the correct response for this country, rather than the capital Mbabane).
3) Change Bujumbura to Gitega (which will result in Burundi being the correct response).
4) The Nur-Sultan type-in being accepted (and the Astana type-in not being accepted) indicates that Nur-Sultan is recognised as the capital of Kazakhstan (notwithstanding the fact that Astana then appears in the list as the response). Therefore, the correct response is Kazakhstan.
5) While Burma and Myanmar are both accepted as type-ins, the listed response should really be Myanmar and not Burma.
Other than that, great quiz!!
