The correct answer is "an area of Soviet-aligned nations following WWII."
This is evident from the map based on the information provided in the key. In the key it states that the purple area symbolizes "Socialist FR of Yugoslavia: USSR aligned until 1948."

The Immigration and Nationality Act of 1965, also known as the Hart-Celler Act, was a bill that was proposed by Representative Emmanuel Celler of New York and it was co-sponsored by senator Phillip Hart from Michigan.
