This speech was given just one month before the official end of the American Civil War. This war caused significant fighting between the Union and the Confederacy. This war caused the deaths of thousands of American citizens on both sides. As this war was winding down, Lincoln knew that these Confederate States would eventual become part of the US again.

When using this phrase, Lincoln is referring to how the Confederate and Union states must work together in order to unite the US once again.
The correct answer is B, since that diagram best explains a cause and effect relationship that has shaped U.S. politics. In fact, restrictions on who can receive public campaign funds have contributed to the persistence of the two-party system.
Public funding of political campaigns in the United States is quite limited, so candidates end up going to private financing. This, in turn, only finances those who have real chances of getting the positions in the voting, which ends up closing the question between Democrats and Republicans, strengthening the two-party system.
