1 Link Russia with the only answer where the 3rd and 4th character is the same
2 Then from that I could see what letter represented R from that there's only one answer where the second letter is an R and the first and third letter are the same so that makes Uruguay.
Those who remember the Cold War might be able to cut a few corners there.
The Cyrillic for "USSR" was famously "CCCP". Now the first "C" is a red herring, of course, but from the rest you can assume C = S and P = R.
Also, a lot of people know that "P" is the Greek character "Rho", because of the Christian "Chi Rho" symbol:
And then of course anyone who's done a lot of maths and physics will have picked up a lot of Greek characters too...
