The correct answer to this open question is the following.
Although there are no options attached, we can say the following.
During Reconstruction, the Thirteenth, Fourteenth, and Fifteenth Amendments were ratified. The issue that these amendments addressed was the abolishment of slavery and voting rights were extended to all male citizens.
Particularly, the 13th Amendment to the United States Constitution referred to the abolition of slavery in the US territory. The 14th Amendment referred to citizenship in the country, and the 15th Amendment granted the right to vote to American men. Not women, just men.
Without a doubt, the Reconstruction Amendments were very important to reuniting and "heal" the country after the American Civil War and rebuilding the Southern states.
