The statement that is NOT true about the Northwest Ordinances is:
B. There were four Northwest Ordinances passed between 1783 and 1790.
There were actually three major Northwest Ordinances: the first in 1784 (which was not fully enacted), the second in 1785 (which established a system for surveying and selling land), and the most significant one in 1787 (which set up a government for the Northwest Territory and included provisions related to slavery).
