40+ quizzes in this series, I noticed that most of the time, when there's a clue about exports, the answer is "oil". I wonder what Greta would think about that...
You should probably replace "captured" with "sold" in the slavery clue. It leads the reader to believe Europeans did the capturing--they did the vast majority of the purchasing, whereas the Africans in and around the area did the vast majority of the capturing and selling.
Great quiz!
Edit: after I took this quiz I hit random and it took me to the Lithuania Country quiz :o
