Because the blacks needed a period of probation and instruction. A period is long enough for the black to have forgotten something of the condition as a slave.
Answer: B. the spread of slavery into the West.
Explanation:
It was an established fact in the years leading up to the Civil War that the South was pro-slavery and the North was Anti-slavery and so both sides had arguments about the spread of slavery into the western territories as those territories gained statehood.
The South wanted slavery to spread into the territories so that they would have more states which would give slavery more representation in Congress and therefore keep the practice going. The North wanted the territories to be free for the same reason.
The second World War greatly reshaped ideas about national identity in America, especially for first-generation immigrants, second-generation immigrants, and African-Americans. During the war - and in the midst of the war effort - immigrants and African-Americans were welcomed into the armed services and, also, in areas of production where support was needed. Many Americans, during this time, were able to somewhat relax or surrender their prejudices. Also, for immigrants and African-Americans, they often felt they were part of American industry and service for the first time.
The correct answer to this open question is the following.
Although the question is incomplete and does not refer to any specific war, we can assume that it refers to the end of the Civil War, when the Confederate General Robert E. Lee surrenders at the Appomattox, Virginia, after the victory of the Union Army led by General Ulysses Grant. The date: April 9, 1865. The two generals had great respect for each other and Grant showed his respect to Lee and had a conversation before signing the terms of the surrender. With the authorization of President Abraham Lincoln, the terms of the surrender were generous because Lincoln really wanted a long term peace and the unity of the nation. The Confederate troops had to turn in their weapons and were allowed to return to their homes.
I think the terms were correct because what was most important at the time was not punishment but unity. The war had killed many soldiers and caused so much damage and pain in the United States. So, Lincoln wanted unity and peace, and that is how he thought about these terms.
