Explanation:

The Northwest Ordinance was composed in 1787 and addressed the need for government in the territory acquired from the Treaty of Paris.

The Articles of Confederation wer the first written constitution but it was enough to govern and that started the Constitution.

The Declaration of Independence is a document written in 1776. If you remember from 6th or 7th grade History, you may have read about John Locke and how Thomas Jefferson used his ideas on social contract and natural right.

Hope this helps :)

explanation:

why

in the 1800s, chinese workers migrated to the united states, first to work in the gold mines, but also to take agricultural jobs, and factory work, especially in the garment industry. chinese immigrants were particularly instrumental in building railroads in the american west, and as chinese laborers grew successful in the united states, a number of them became entrepreneurs in their own right. as the numbers of chinese laborers increased, so did the strength of anti-chinese sentiment among other workers in the american economy. this finally resulted in legislation that aimed to limit future immigration of chinese workers to the united states, and threatened to sour diplomatic relations between the united states and china.
