Can someone please help me answer this common lit assessment question, and if you know the other one please state it. Thanks

mali had been a state inside of the ghanaian empire. after ghana fell because of invading forces and internal disputes, mali rose to greatness under the leadership of a legendary king named sundiata, the "lion king." the songhai empire, already weakened by internal political struggles, went into decline.

i would say b. research typically uses a variety of sources

sounds good to me mate!
