Russia is a transcontinental country, even though 77% of Russia is in Asia, I am using the United Nation countries list to determine the countries that are in Asia. On the list, the United Nations considered Russia to be in Europe since the majority of Russians are eastern Europe or Slavic, I will be considering Russia to be in Europe. I have created another quiz just like this, but it is all about Europe which I haven't released yet. Thanks for pointing it out and telling me.
This is the link for the website that I used :
