Answer:
(A) A time period where the South needed to rebuild
(D) Infrastructure would need to be rebuilt.
Step-by-step explanation:
During the Reconstruction Era, the South needed to do much rebuilding because most of the war took place there. Plantations and property were destroyed. The economy was mostly based on farming, and slave labor was no longer an option. Because so much was destroyed, they had to rebuild infrastructure.
---------------------
Former slaves were not welcome by Americans, especially in the South. They faced discrimination and many were poor and uneducated. Laws in the South called Black Codes were created to prevent Blacks from exercising their freedom properly. Option B is incorrect.
The North did not need to rebuild because they had many economic advantages during the war. This included factories thriving during the war, a good system of train lines and roads, and employers being used to pay wages. Additionally, the war didn't really take place in the North.
Thus, the best answers are A and D.
hope this helps!
