Which was the greatest challenge for both American settlers and American Indians in the West in the mid-1800s? A. the exposure to harsh weather

B. the threat of deadly diseases

C. the danger of crossing difficult terrain

D. the problem of fenced-off land

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.
