Questions: Which of the following was a promise of the Northwest Ordinance of 1787? A The West would be considered a colonial possession of the United States. B Slavery would be banned north of the Ohio River. C Native Americans would be forced to move to the Pacific coast. D The population of a territory would never affect whether it was to become a state. E Territories must adopt the national Constitution before writing their own.

The answer is B) Slavery would be banned north of the Ohio River.

This option is incorrect. The Northwest Ordinance of 1787 was designed to establish a framework for the governance of the Northwest Territory and to provide a method for admitting new states to the Union. It did not treat the West as a colonial possession but rather as a region that could eventually become part of the United States as new states.

This option is correct. The Northwest Ordinance included a provision that prohibited slavery in the Northwest Territory, which included the land north of the Ohio River. This was a significant step in limiting the spread of slavery in the United States.

This option is incorrect. The Northwest Ordinance did not include any provisions that forced Native Americans to move to the Pacific coast. It did, however, include language that recognized Native American land rights, although in practice, these rights were often ignored.

This option is incorrect. The Northwest Ordinance established a process for territories to become states, which included reaching a certain population threshold. Once a territory had 60,000 free inhabitants, it could apply for statehood.

This option is incorrect. The Northwest Ordinance required that new states formed from the territory adopt a republican form of government and that their constitutions be consistent with the principles of the national Constitution, but it did not require them to adopt the national Constitution itself before writing their own.
