"They had to form a new government with 10% saying slavery was illegal" needed to happen before a state could be readmitted to the Union after the Civil War.
Answer: Option C
Step-by-step explanation:
The recreation of the South after the civil war is called reconstruction. The reconstruction lasted from 1865 to 1877. The goal of reconstruction was to help southern countries re-join the Union. During reconstruction, federal troops occupied a significant portion of the south to ensure compliance with the law and the absence of a new uprising.
After ending the civil wars, Abraham Lincoln wanted states to join the union in a much more liberal manner. He eased the process for them and made it mandatory that is a state has to be rejoined to the union after ending the civil war, the state must create the new government with 10% saying that slavery was illegal. However the Congress was not in favor of this and made the laws more stringent for the southern states.
