boo-ya, I'm a Zimbabwean and I got 100% I thought of doing making a similar quiz, glad I checked if there was one before I started. Mine would not have been as cool.
Great idea for a quiz! I unfortunately only got the 4 most guessed answers, but I was pleased to see that I recognized all but one of the other answers. Doesn't mean I ever would have remembered them on the quiz, but at least I've heard of them.
I listened to South Africa's national anthem before, which has 5 languages (Xhosa, Zulu, Sesotho, Afrikaans, and English). I guessed Swazi when typing in Swaziland. Missed the other 5.
English and Afrikaans - both easy
Zulu is pretty well known, so also easy
I got Sesotho and Swazi, just because of Lesotho and Swaziland.
I managed Xhosa, because I once met a white South African who could speak some, and I remember how crazy it sounded with all the clicking.
The rest I have never heard of.
