Immigration quotas established by Congress in the 1920s ______________.

A) reflected a desire to increase immigration
B) favored northern Europeans
C) were opposed by labor unions
D) were opposed by business executives

The immigration quotas established by Congress in the 1920s favored northern Europeans and restricted immigration from other parts of the world. This was due in part to fears of increased competition for jobs from immigrants and a desire to maintain a predominantly Anglo-Saxon culture in the United States. The quotas were also supported by some labor unions who believed that limiting immigration would help protect American workers. However, the quotas were opposed by many business executives who relied on cheap immigrant labor.
