Based on your knowledge of world history and the passage, Mansa Musa’s assertion about the lack of duties levied on goods in his kingdom most strongly reflects which of the following about the kingdom of Mali?

(A) Mali’s wealth came in large part from its exploitation of minerals. (B) Mali’s wealth came in large part from its conquest of pagan neighbors. (C) Mali’s wealth came in large part from large agricultural estates. (D) Mali’s wealth came in large part from the exploitation of the slave trade.Explanation: If a king boasts that he does not need to exact taxes (duties) in his kingdom, it means that his kingdom is rich. The passage discusses in large part Mali’s mineral wealth so eliminate answer choices that do not discuss mining. Eliminate (B), (C), and (D) for this reason. Choice (A) is thus the answer.
