Question

why would the u.s. government set up a quota system for immigrants?
a. people feared and did not understand foreign cultures and religions.
b. there were too many people in the u.s., so they wanted to limit the number of people entering.
c. this allowed more migrants to come to the u.s.
d. these were systems that allowed americans to learn more about foreign cultures.

Explanation:

Quota systems are often implemented due to concerns about cultural and religious differences. In the context of U.S. history, there were periods of nativism where people feared and misunderstood foreign cultures and religions, leading to the establishment of quota systems to limit immigration from certain regions. Option b is incorrect as population numbers weren't the main driver; option c is wrong as quotas limit, not increase, migrants; option d is incorrect as the purpose wasn't cultural learning but restriction.

Answer:

a. People feared and did not understand foreign cultures and religions.
