Which acts limited immigration and favored Northern and Western Europeans based on the 1910 census?

The correct answer is based on the Quota Acts of 1921 and 1924, which established immigration restrictions that specifically favored Northern and Western Europeans. These acts set quotas based on the racial and national makeup of the U.S. population as determined by the 1910 census. Under this law, a certain percentage of immigrants from each nationality could enter the U.S., which significantly favored countries like Great Britain, Germany, and the Scandinavian nations, while severely limiting immigration from Southern and Eastern European countries, as well as Asia.

The 1921 Act introduced numerical limits on immigration and was further refined by the 1924 Act, which solidified the quota system and aimed to reduce the influx of immigrants from regions deemed undesirable at the time. This discriminatory approach reflected the nativism and xenophobia prevalent in the U.S. during the early 20th century.

In contrast, options such as the Immigration and Nationality Act and the Emergency Quota Act do not specifically reference the 1910 census or the same discriminatory quota structure aimed specifically at limiting immigration from certain groups based on ethnicity or nationality. The Chinese Exclusion Act, while also an important piece of immigration legislation, was focused specifically on barring Chinese immigrants rather than establishing broader immigration
