Answer:
Successes of the reconstruction efforts were, black businesses and churches grew, many schools and black colleges were constructed, citizens were given more rights, and the passing of 13th 14th, and 15th Amendments. I believe that the reconstruction efforts should have continued longer because, they were barely effective, to begin with, and a lot of the progress made was lost, due to the fact that the policies made could be easily reversed.
