Explanation:
The Immigration Act of 1924 was meant to replace the Emergency Quota Act of 1921 and was intended to curb the growth of the migration of southern Europeans, mostly Roman Catholics, and Slavs and Jews from Eastern Europe, who had begun arriving in the United States in large numbers from the 1890s, and to prohibit the entry of Asians, Indians and non-European citizens who were not eligible for naturalization.
