How did the Immigration and Nationality Act of 1965 impact an earlier law that had been passed in 1952?

The 1952 Immigration and Nationality Act retained a national-origins quota system, although it made some changes to it. The 1965 act ended that system and replaced it with preferences focused on family reunification and worker skills. Thus, it removed the quota system the earlier law had helped maintain; the correct choice is “It removed the quota system that the earlier law had helped to maintain.”
