The correct answer is B. Establish requirements for admitting new states to the Union

Explanation:

The purpose of the Northwest Ordinance of 1787 was to officially define and integrate territories that belonged to a region known as Northwest. This was required because the Northwest territories previously belonged to England and due to this, the Congress of Confederation (government of the time) did not have complete control over the territory.

Through this ordinance, the government ratified its power over the territory, guaranteed rights, and established requirements to admit states to the Union. This last accomplishment included the number of states that will be formed in the territory and the fact these will be free states (slavery was not allowed). According to this, the one that was an accomplishment was "Establish requirements for admitting new states to the Union."

when studying cause and effect, historians usually group the causes into different categories. for example, cultural causes reflect how a society’s literature and art convey the way the society saw itself in relation to the rest of the world. another resource that historians use to understand society is pop culture, which tells them the trends and ideas that are preferred by the common people. when studying cause and effect, it’s important to remember multiple causation, or the idea that an effect could have several causes and vice versa.  

the correct option is “cultural causes” since art and literature are related to the culture of a place. culture is determined by literature, art, music.

the correct option is “pop culture” since it reflects the likes and ideas of common people whereas the rest of the options do not focus on common people.  

the correct option is “multiple causation” since it refers to the idea that events are caused by multiple reasons, not just a single one.  

your answer would be just capitalism.
