What was the most important result of the land ordinance of 1785?

The answer is "  It provides an arrangement for the expansion of US borders".

Explanation:

The 1785 New law brought the 1784 resolutions into effect by establishing a framework for the sale and settlement of the property, whereas the 1787 Northwestern New law discussed political interests.  

The New law of 1785 established the land law foundations until the Homestead Bill of 1862 passed, that motivated settlers to have the 13 state governments completely settled, and helps to bring the country cash by the selling of public property

this null effect is caused by a weak manipulation and ineffective internal validity. in a scientific study, as the one dr. morimoto is trying to perfom, internal validity refers to the confidence placed in the cause-effect relationship and to how well an experiment is done and able to eliminate confounding variables.
