Answer: Propaganda
Explanation:
When Abraham Lincoln said these words, he meant to show that the United States could not continue if the North and the South had differing opinions on slavery and that in the end only one view would stand. Seeing as he was a Republican which was a party opposed to slavery, we know what view he supported.
He therefore used the quote above as propaganda to push forward his views on the division in country.
The correct answer is " Citizens would be able to form governments that ensure their interests."
The idea of a social contract involves citizens of a country giving up some of their individual liberties (aka freedoms) so that the government can make society safer. Hobbes argued that this social contract, despite the fact that it limits individual freedoms, will benefit citizens because they have the opportunity to pick their leaders who will make laws based around their wants/needs.
