How did the invention of television change the nature of political communication? a) it made other forms of media like newspapers and the radio obsolete in terms of spreading a message. b) it gave the public audience the ability to see what officials looked like and see the effects of their actions. c) it caused people to spend more time consuming entertainment programming rather than political events. d) it led to the creation of regulatory agencies that prevent news stations from taping public officials' speeches.

labor leaders and organizations had the power to demand it.

explanation:

workers got a five-day workweek because the bcea protects and respect the rights of the employees. labor leaders and other groups demanded it.

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.
