Answer 1

The correct answer is A) By the end of the Civil War, black men made up nearly ten percent of the Union Army. 

In 1870, Revels argued before the Senate that "the people of the North owe to the colored race a deep obligation that is no easy matter to fulfill". The piece of evidence that would best support the statement is " By the end of the Civil War, black men made up nearly ten percent of the Union Army."

Hiram Rhodes Revel (1827-1901) was the first African American to serve in the United States Congress. He was a Republican Senator for the state of Mississippi. He entered the Senate in 1870 and his oratory skills as a preacher help him to deliver his messages in Congress. After some opposition from the Democrats, Revels finally was accepted in the US Senate and was assigned in the Committee of Education and Labor.
