Final answer:
Countries that use several languages have linguistic pluralism.
Step-by-step explanation:
Countries that use several languages have linguistic pluralism. Ethnocentrism, geocentrism, and high uncertainty avoidance are not directly related to the use of multiple languages. Ethnocentrism refers to the belief that one's own culture is superior to others, geocentrism refers to the belief that one's own country is the center of the world, and high uncertainty avoidance refers to the preference for clear and structured rules and avoidance of ambiguity. Linguistic pluralism, on the other hand, is the presence of multiple languages within a country or region.
