Answer:
The United States followed a strict policy of Isolationism and did their best to stay away from the war. They did this in part because they had just come out of the Great Depression and their economy was just starting to take off again and they feared entering the war would bring them back into economic crisis.
The correct answer to this open question is the following.
If the question refers to the Westward Expansion from 1807 to 1912, that made thousands of pioneers to cross the Oregon Trail, then some possible consequences of the rapid settlement of Oregon would be the occupation of lands to be used as farms and get people new opportunities to make a decent living growing crops. The rapid settlement was notorious by 1840. Oregon lands "promised" fertile soil. That is why people from the Mississippi Valley decide to move to Oregon. Mane Eastern farmers decided to better move to Oregon instead than New Mexico or California, thinking that the land in Oregon was more fertile to farmland. People had to cross the above mentioned Oregon Trail, knowing that the trip would not be easy.

The North was in favor of tariffs, while the South hated tariffs. This was because the North was focused on industrialization and the South was focused on agriculture.
A tariff is essentially a tax on foreign goods. It helped protect factories and businesses within the United States, as it made people want to buy from their own country since there was no foreign tax. This was <u>good for the North</u>, as more people were buying their products as opposed to them buying elsewhere. This was <u>not good for the South</u> though, as the South normally sold their goods overseas. This made their products look less desirable to foreign countries, as there was now a tax on them. The South also was buying a lot from overseas, but now it was more expensive.
