What is its main Purpose? - What are the other Accompanying Objects that it works with? ] .pull-right[ - What are the **current Settings** for each Knob? - Change the Setting of Each Knob to its **natural opposite extreme**. What Happens? - You will see that in many cases, each Knob creates a Certain Outcome at one Setting and another Outcome at the Opposite Setting. - This is the Source of your Administrative Contradiction !! ] What sort of Contradictions do we see in these familiar objects? What is good and what is not so good?
