Correct answer: D. To help former slaves make the change to freedom
Details:
The Freedmen's Bureau was established by Congress in 1865, in the aftermath of the Civil War. The aim of the Bureau was to provide assistance to former black slaves (as well as poor whites) in the South during the Reconstruction period. The Freedmen’s Bureau provided food and housing, established schools, and made medical and legal assistance available. There was an intention of settling former slaves on land confiscated or abandoned during the war, but that didn't materialize. Radical Republicans took over dominance in Congress and they determined that confiscated lands in the South should be returned to their original owners.
If I remember correctly, the answers are A and D.
In 1864 houston was connected to the rail system
