Under radical reconstruction, which of the following did former confederate states not need to do in order to rejoin the union?

pass the fourteenth amendment
pass the fifteenth amendment
revise their state constitution
allow all freed men over the age of 21 to vote

allow all freed men over the age of 21 to vote

Explanation:

The Reconstruction is the period that followed the American Civil War, during that time the Union developed a series of policies to reconstruct the nation because of the destruction of war.

The first action the Republican majority took was the First Reconstruction Act that split the South into 5 districts that would have martial law.

During that period, Southern states needed to draft new constitutions that guaranteed African-American men the right to vote and they also needed to ratify the Fourteenth Amendment that guaranteed African Americans equal protection under the law.

i believe the correct answer is option b. most eastern european nations joined nato.

though i could be wrong, option d. the eastern european nations were granted complete independence, would be another choice.

hope this ! : )
