Question

what effect did the immigration act of 1965 have?
a. florida’s immigrant population declined dramatically.
b. asians immigrated to the northeast in great numbers.
c. big cities in the midwest lost a large percentage of their foreign - born population.
d. southwestern border states such as arizona experienced massive population growth.

Explanation:

The Immigration Act of 1965 abolished the national origins quota system, opening immigration to more non-European groups. It led to significant growth in immigrant populations in U.S. border states, especially southwestern ones like Arizona, as migration from Latin America and Asia increased. The other options are incorrect: Florida's immigrant population grew, Asian immigrants settled widely not just the Northeast, and Midwest big cities did not lose large shares of foreign-born populations.

Answer:

D. Southwestern border states such as Arizona experienced massive population growth.
