Nicholas Appert. I did a unit on him.
I would say that the sectional tensions strengthened during the 1850s mostly because of slavery. As you already know, historically, the North and the South of US were very different. The North went out of its way to abolish slavery, whereas the South was pro-slavery. This is what created many tensions, and later on, even more wars between these two sections.
The correct answer is a Credit Union.
Credit Unions are able to charge lower rates than a bank because of their structure. Banks are set up as a for-profit business, so they charge more in order to make themselves more profitable. Credit Unions are set up like cooperatives where the customers own them, or like a non-profit organization. This allows Credit Unions to charge lower rates. Additionally, the Credit Unions normally distributes the profit back to the customer.
