Explain the increase in violent conflicts in the western united states in the late 1800s?

This was caused by the increase in migration by white settlers.

Explanation:

From the late 1800's lots immigrants were entering the United States from Eastern and southern Europe. Millions of immigrants and poor farmers arrived in cities of New York, Boston, Philadelphia, St. Louis and Chicago,

immigrants live separately in a different neighborhood and a number of them kept their own customs and tradition.

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.
