Which factor contributed to the fall of communism in the soviet union? war with the united states the election of vladimir putin the policies of glasnost and perestroika strikes and reforms in satellite countries

the policies of glasnost and perestroika

Explanation:

During the 80's the soviet economy was in deep trouble as it had not adapted  to the changes and new challenges presented over the years. In 1985 Mikhail Gorbachov became the head of the Communist Party and realized some changes needed to be done. He launched the Perestroika which were a series if political and economicl reforms to help the Soviet Union's economy. As a second support for the change the Glasnost was created, it referred to their policy of open discussion of political and social issues. All these lead to the collapse and democratization of the Soviet Union as they realized that their old methods were not sustainable anymore and critical changes needed to be done.

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.
