<u> A) Limit the number of immigrants from a given country.</u>
The Emergency Quota Act of 1921 was temporary legislation in the United States that established a quota system to limit the number of immigrants from a given country. The law annually provided immigration visas to 3% of the total number of people of each nationality living in the U.S., based on the 1910 national census.

And People of Northern Europe, who had similar cultures with Americans were benefited the most: They had a higher quota and were more likely to be admitted to the U.S.
