How did nationalism impact ethnic and cultural identity on a global scale? Please Help asap

Nationalism is a worldview that takes its starting point in the community within the borders of nations. Nationalism pays homage to the nation, culture, history and safeguards the nation state and its interests. Anyone who professes nationalism is called a nationalist.

Thus, the conception of nation also implies for nationalists the existence of a people, that is, a society with common cultural and ethnic characteristics that differentiate it from other nations, and give individuals a sense of belonging to that nation. In this way, nationalism can promote in certain cases clashes between that ethnic and cultural identity and the cultural expressions or minority ethnic identities found in a given society or nation.

the correct answer is “opportunity cost”. opportunity cost is what a company misses out because it decided in one option over another one. in this case, the company decided to invest in building a factory so it gave up another possible benefit or profit in order to achieve success with the factory.  

trade-off is not the correct answer since it is a situation in which you accept losing something in return for benefits in other areas.

and finally, consequence is a general term used to accept what it comes when you make a decision. it can be a positive or negative consequence depending if the decision you took was the correct one.
