Answer:
Multiculturalism
Step-by-step explanation:
Multiculturalism is the belief that society benefits when many different cultures coexist in the same geographic area.
Adherents to multiculturalism defend the right of minority or immigrant populations to preserve aspects of their culture, while at the same time promoting cultural exchange with the culture of the dominant group or the host country.
The United States is an example of a multicultural society because vastly different cultures coexist in the same geographic area, due to the country's ethnic diversity, and large amount of immigrant population.
