The correct answer is A. It prohibited slavery in the Northwest Territory.
Explanation:
The Northwest Ordinance was approved in 1787 to establish the Northwest territory and laws that applied to it. This covered states such as Ohio, Wisconsin, Illinois, and Indiana. Additionally, the Ordinance established the borders of this territory or states that were part of it, ratified the sovereignty, and established a local government.
Also, the ordinance ratified natural rights for all those in the territory, and therefore prohibited slavery and any similar practices. Due to this, after the ordinance, many slaves from the South scaped to this territory to gain their freedom, which contributed to the issue of slavery and related conflicts. Thus, the statement that is true about this ordinance is "It prohibited slavery in the Northwest Territory."
In my view the period that has had the biggest impact on the development of US society is The Great Depression. That depression brought a huge economic growth but also changed mass culture that swept many Americans into consumer society.
