Ugh, so I did. Fixed. Interesting one to consider though - if there are Asian countries east of Palau, could Palau make a pitch to describe itself as Asian?
The question is not easternmost in the eastern hemisphere. Easternmost simply means the farthest to the east in the region called Oceania--Tonga & Samoa!
Though technically Kazahkstan goes into what is widely considered the European continent, 1. Some do not consider it to cross into the territory of Europe, 2. It is to almost all people not culturally considered part of Europe. It shouldn't be placed in this quiz.
There is another strong argument in my opinion: French Guiana. By this logic, not Paraguay but France would be the fifth most eastern country in South America.
