Question

which law created quotas that made it harder for southern and eastern europeans to immigrate to the united states and easier for northern europeans?
the chinese exclusion act
the immigration act of 1917
the emergency quota act
the johnson - reed immigration act

Explanation:

The Johnson - Reed Immigration Act of 1924 established quotas based on national origins. It favored northern Europeans over southern and eastern Europeans by setting lower quotas for the latter groups, aiming to preserve the existing ethnic composition of the United States. The Chinese Exclusion Act targeted Chinese immigration, the Immigration Act of 1917 had a literacy test and other restrictions but not the specific quota system for European regions as described, and the Emergency Quota Act of 1921 was a precursor but the Johnson - Reed Act was more comprehensive in its discriminatory quota system.

Answer:

D. the Johnson - Reed Immigration Act
