Answer and Explanation:
1. Ethnocentrism is the term that refers to the habit that an individual has to judge foreign cultures and ethnicities based on their own culture and ethnicity. This ends up generating cases of intolerance and xenophobia, moreover, when ethnocentrism is defended by governments and governments it can generate large scale conflicts, leading to wars and very serious and serious socioeconomic problems, as it proposes the suppression of an ethnicity in favor of another who tries to protect himself ends up in a large-scale conflict. An example of this is that it can be recognized with German ethnocentrism towards Jews during Nazi Germany.
2. Cultural diffusion allows for an exchange of cultural concepts in different cultures, which causes a mixture and a greater acceptance of cultural and ethnic differences that exist between two nations. This diffusion allows for an increase in tolerance and understanding between differences, which does not allow one culture to feel more worthy than another and try to decimate it. In this case, we can say that cultural diffusion is able to reduce ethnocentrism.
3. The widespread use of technology has promoted cultural progress. This is because it allowed cultures to have greater contact with each other, in addition to promoting that individuals from each culture had access to information different from what they were used to, especially in more isolated cultures and in countries in precarious socioeconomic situations.
