During 1200-1450, Mali, a big empire in west Africa flourished. Timbuktu, a city in this empire had a huge library with tens of thousands of books. This library provided their empire a lot of wealth. During 1400-1750, during the Atlantic slave trade, millions of African people, mostly men and some women, were transported to South America via the Atlantic Ocean. The rulers of West Africa negotiated with European rulers to send off their Africans. In exchange, the Europeans gave them silver which boosted the wealth in their economy.
The correct answer would be C they have often erred.
If that isn't correct, then try B. yet I don't recall them being "out to get him"
Hope this helps

A. A person with a higher income pays more money in taxes.
A progressive tax's percentage is dependent on what income bracket you are in. So if you are in a higher income bracket (you earn more) then you would pay a bigger percentage than someone in a lower income bracket. That is why it is a "progressive tax", because it gets progressively bigger.
