Explain how WW2 impacted Americans

America's involvement in World War II had a significant impact on the economy and workforce of the United States. ... American factories were retooled to produce goods to support the war effort and almost overnight the unemployment rate dropped to around 10%.

Explanation:

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.  

it was the new england colonies.
