Its 1 because 3 and 4 relates to a monarchy and 2 isnt what happened
Northern: No slaves, mostly republican (our democrat) ideas, economy was based on trade and business
Southern: Slavery was supported, mostly (our idea of) republican, their economy was based on plantations and slaves

What changed americas view of ww1 was freedom and liberty i think thats right.
Because there was no actual violence occurring. The problem was that the Berlin Wall was up, so the U.S teamed up with Britain and France to fight a “war” by delivering supplies by air dropping it over the wall. So while they were fighting with the gov. In some type of way. There was no real violence going on.
