Final answer:
The presence of mosques in the United States is an example of cultural diffusion, the natural spreading of culture through means like migration and trade, rather than cultural imperialism or assimilation. Therefore correct option is B
Step-by-step explanation:
The presence of mosques in the United States, such as the Masjid Al-Faatir Mosque in Chicago, is an example of how a country's culture can be modified through diffusion. Cultural diffusion refers to the spreading out of cultural attributes like beliefs, ideas, and social activities from one central point to different regions. This process can occur through various means such as migration, trade, and the exchange of information. Examples of diffusion in history include the spread of Islam, as Muslims migrated and established Islamic institutions in new communities, or global brands like McDonald's becoming present in almost every country.
Assimilation is a related concept, but it implies that a minority group has started to adopt the customs and attitudes of the host culture, often losing its original identity in the process. However, cultural imperialism is when a dominant culture forcefully imposes its culture on another, rather than a mutual exchange or natural blending of cultures over time.
