Answer: a. to make it easier for Southern states to reenter the Union after the Fourteenth Amendment was passed
Explanation: The passage of the Military Reconstruction Act of 1867 was primarily to address the problem of readmittance of former Confederacies and the reinstatement of all their rights which was not well favored by the victorious Union, mainly the Congress in the years following the civil war. The victorious Union felt it necessary to punish the former Confederacy before their reinstatement. This act was not supported by Radical Republicans who passed the Military Reconstruction Act to aid the readmittance of the former Confederacy into the Union.
