What groups of people did the quota system negatively impact?

Eastern and southern Europeans were most severely affected by reductions in legal immigration. The “national origins” quota system to limit immigration selectively was quantitatively discriminatory and would remain the primary principle determining admissibility to the United States until 1965.

i believe the correct answer is option b. most eastern european nations joined nato.

though i could be wrong, option d. the eastern european nations were granted complete independence, would be another choice.

hope this ! : )
