The correct answer is B. A hamburger restaurant in the United States
Explanation:
The term cultural diffusion refers to the spread of certain cultural features from the place where they originated to other cultures or human groups. This implies cultural diffusion is about ideas, customs, beliefs, languages, and others that are integrated into different cultures to the one in which they originated. This leads to external influences in the culture of a group or cultural mixes as one culture can include features of other cultures. In the last century, as a result of the development of communication technologies and globalization cultural diffusion has become common, which means it is common to find features from external cultures in almost all the cultures around the world. Considering this, the one that is not an example of cultural diffusion is "a hamburger restaurant in the United States", because hamburgers are part of the culture of the U.S. but if they remain in the U.S. as in this case there is no cultural diffusion.
