The answer to your question would be manifest destiny. i am pretty positive good luck and study hard.
The Great Depression began partly because of inflation, the federal reserve was putting a lot of currency into circulation without the gold and silver to back it up. Another reason was a rise in immigration. Many immigrants were coming from the east to experience the "New World" and get a second chance at life, however this caused lack of housing and job availability. There was also a drought in what we know as the "Dust Bowl". Most of the Northeastern part of the US was industrialized, so most of our food was grown in the northwest and the south. However because of the drought food wasn't as easily accessible as it was before, and if you did manage to find some at a market, inflation combined with the increased pricing made most foods nearly impossible to buy. Lastly there was the "Great Immigration" this is when a large number of people began to move south west looking for better opportunities. This should have been a good thing considering the influx of immigrants from the east, however this only created more problems. While those people left, their jobs were not filled because of the inflation, so their previous employer couldn't afford to hire anyone else. This happened thousands of times, and a lot of jobs were left unfilled and businesses shut down because they didn't have the money or the work force to continue to operate. This lead to a lot of people with very little money, no job, and because of the culture back then the people usually had a family to take care of. This became a cycle that triggered the great depression. I don't know if any of those are answer choices but I hope this helps!
