Will mark as brainiest if correct!

One method that Mao Zedong used to improve farm production was through the creation of which of the following ?

he didn't think it was ethically wrong. he thought it was not going to work and it was not going to be of any assistance. he wrote about that in his memoirs.

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.
