Answer:
D) prejudice and economic concerns.
Step-by-step explanation:
I would go with the answer D here based off the following reasoning:
Firstly, the theory of internationalism would mean to develop on a international stage, which isn't what the diagram is showing, it is showing restriction of immigrants into America(the funnel is acting like a filter to illustrate how America is only letting so few people of the many trying to enter). Therefore it doesn't quite look like A)
Option B doesn't really make sense because it summarizes victory in Europe, which is really just restating internationalist policies and more refers to Wilson's interests to sustain democracy and make the world a safer place in entering the war in the first place. Though it alludes to America's dominant markets, there is a more direct answer.
Option C is on the right track, but the image isn't really showing a protest or something that shows demands for inclusion, its really showing what the reality is and that America isn't including.
That leaves option D, which makes the most sense. As nativist policies of white supremacy continued, that left no room for the Asian and eastern European migrants which consisted of a majority of the immigrants attempting to enter the U.S. Additionally, the returning soldiers from war were already struggling to find work as the Great Migration had left zero space for them in the labor force. Recall the Great Migration was an African American movement from the South to the North in the early 20th century for African Americans escaping Black Codes, Jim Crow societies, and entry into a labor force. This therefore generates that economic concern, and ultimately results in the Coolidge passing the immigration quota act in 1924, and so on so forth.
Hope this helps
