Answer: C. People in Japan watching Disney movies
This is an example of Japanese culture taking in culture from the United States. So the two cultures blend together in a way.
Choice A can be ruled out as it doesn't mention anything about other cultures.
Choice B can be ruled out as well for similar reasons, and I'm assuming polka music is of German origin.
Choice D can be ruled out because Michigan is a state in the United States, so we aren't mixing two different cultures from two different countries.
