The right answer is “C. In the second inaugural address, saving the Union is the purpose of the war.”

The second inauguration of Abraham Lincoln in 1865 had the shortest speech of all: only 700 words. Speech is one of the most important in American history, as it happened on the eve of the end of the Civil War between the north and south of the United States. Lincoln asked for a country “without wickedness, with charity for all, and steadfastness in the right which God has given us to see the right.”
