What was one thing the bureau was responsible for?

(Hope this helps) The U.S. Bureau of Refugees, Freedmen and Abandoned Lands, popularly known as the Freedmen’s Bureau, was established in 1865 by Congress to help former black slaves and poor whites in the South in the aftermath of the U.S. Civil War (1861-65). Some 4 million slaves gained their freedom as a result of the Union victory in the war, which left many communities in ruins and destroyed the South’s plantation-based economy. The Freedmen’s Bureau provided food, housing and medical aid, established schools and offered legal assistance. It also attempted to settle former slaves on Confederate lands confiscated or abandoned during the war. However, the bureau was prevented from fully carrying out its programs due to a shortage of funds and personnel, along with the politics of race and Reconstruction. In 1872, Congress, in part under pressure from white Southerners, shut the bureau.

The main purpose of America's Declaration of Independence was to explain to foreign nations why the colonies had chosen to separate themselves from Great Britain.
