Question

Which was a main reason for the flux of immigrants entering America in the early 1900's?

A)
Immigrants hoped to seek economic opportunity.
Eliminate

B)
People were fleeing Europe during World War II.


C)
The California Gold Rush offered hope of quick fortune.


D)
The United States needed more people to settle in western states.

Answer 1

I think the answer is A: Immigrants were hoping to seek economic opportunity.

World War II wasn't until 1939.
It can't be the California Gold Rush because that was 1848 - 1855.
It possibly could be D. but it was more the Americans that were settling in the western states. 

So I would say A. is the answer!
Hope that helped! :)
