Answer:2. ten percent of a state’s citizens were required to swear loyalty.
Explanation: Initially in 1863, the Wade--Davis Bill proposed by President Abraham Lincoln and the Congress was made as framework for Reconstruction under the provision that if the North won the civil war, it will require 10 percent of their male population or state to swear loyalty oaths in order for the Confederate states to be recognized and readmitted into the union. However, a more harsher plan was proposed(after concluding that the former was too mild ) by Senator Benjamin F. Wade and Representative Henry Winter Davis in February 1864 which required that 50 percent of the state take a loyalty oath to swear allegiance in order to be readmitted to the Union.
