<span>The Dred Scott Case furthered the gap between abolitionists and slaveholders. By asserting that a slave was property and had no free will or agency, the northern states dug deeper into the abolitionist movement. This also spurned many to stop further acquisition of slaveholding lands in order to maintain free states and places where slaves couldn't be found. By having a mission to stop the spread of slavery, this put a strangehold on land starved plantation holders who saw the western acquisitions of the Mexican Cessation as potential cotton or tobacco lands. Stopping their spread made the southern states feel oppressed and furthered their own wishes to keep their own standard of living.</span>
Following the American Revolution, the Confederation Congress was unable to resolve the nation’s economic crisis because it could not "tax the states", which was required if enough revenue was to be raised to pay back the war debt.

Those other options are there to trick you
I think you forgot to give the options in this question. I am answering this question to the best of my capability and hope that it helps you. An economic downturn can cause the demand curve to shift left. During this time actually the demand of a product in the market falls and so the producers have to lower the price of the products as well.
The correct answer is: frontier farming became easier because there were new tools that helped break the soil faster. However, even though there were many useful tools for farming, it was also difficult for people to get a job since the machines were taking their places.
For example, there were new machines such as farming with windmills, steel plows and reaping machines which made harvesting quick and easy.
Nevertheless, it was hard for farmers to pay for these tools and put them in debts. They dealt with economic problems as crop prices dropped and their debts grew.
