The correct answer to this open question is the following.
Although there are no options attached we can say the following.
How did the Freedmen's Bureau affect the lives of the formerly enslaved African Americans living in the South?
The Freedmen's Bureau affected the lives of the formerly enslaved African Americans living in the South in that the US Congress approved the establishment of the Freedmen's Bureau in 1865 to assist these people with medical attention, food, shelter, and education.
Unfortunately, there was not enough money to accomplish these, besides the political "climate" in the racist's southern states never accepted this Freedmen's Bureau.
In a time of economic problems and political instability, the Freedmen's Bureau was a real help for former black slaves and poor white people that lived in the south and practically had nothing after the conclusion of the American Civil War.
