Name three important similarities shared by the Presidential and Congressional plans for Reconstruction.

The correct answer to this open question is the following.

The first similarity shared by the Presidential and Congressional plans for Reconstruction was that both plans wanted to reintegrate the Confederated states, although through different means. The second was that both plans referred to a percentage of people to pledge allegiance to the Union, although the percentages of the President plan and Congress plan were vastly different. And the third was that both plans aimed to abolish slavery in the southern states, although President Lincoln's plan was much more lenient.

The 10% Plan was the foundation of the Reconstruction plan for Lincoln. 10% of citizens had to take the oath to serve the Union, the southern state could be reintegrated. The Congress plan, led by Radical Republicans demanded more than 50% of people to take the oath.
