Question

quotas and limitations
in 1965, the united states passed the immigration and naturalization act.
this act abolished the immigration quota based on national origin.
this meant that the united states could not turn someone away from immigrating to the united states based on where they were from.
however, this bill also put a limit of 120,000 people who could immigrate to the united states per year.
the reason for this restriction was the suffering economy.
what did the 1965 immigration and naturalization act do?
eliminated immigration into the united states entirely
abolished immigration quotas based on national origin
removed all restrictions on immigration into the u.s.

Explanation:

The text clearly states that the 1965 Immigration and Naturalization Act abolished the immigration quota based on national origin. It did not eliminate immigration entirely (as it set a yearly limit of 120,000) and did not remove all restrictions on immigration.

Answer:

B. abolished immigration quotas based on national origin
