In the </span>North, slavery was almost universally prohibited <span>by the </span>1800s<span>, while the institution was a cornerstone of </span>Southern<span> society.</span>
Unfortunately, you didn't share any following reasons so that someony could choose the correct one, but I am pretty sure that I can help you and name the main factor. Definitely, the point which caused a decrease in the size of the armed forces at the end of the cold war is that the US promised to decrease its armed forces as part of the peacetime agreement. I bet it will help you!
First off, Are you taking AP GOV right now.
There are 2 types of systems, Entitlement and Means Tested.
Means Tested is you have to meet a certain criteria and have a special need for the credit ( either money or food stamps ).
Examples include Medicaid and Food Stamps.
Hope this helps!
