designing a process generating output giving feedback setting a goal
I gave my students this multiple choice question: After a windstorm, Niko called the electric company to report that he had no electricity. His phone call is an example of which of the following elements of a universal systems model?

Only one answer is correct among these 4 choices:
- designing a process
- generating output
- giving feedback
- setting a goal

Could you tell me which one is correct?

giving feedback
