Final answer:
The "Americanization" of Europe started to reverse with the cultural extremes and transformational change of the 1960s.
Step-by-step explanation:

This decade saw a shift away from the idealism and excesses of the late 1960s in America. The counterculture movement offered an alternative to the conformist culture of middle-class life and paved the way for multiculturalism and cultural dissent.
