Second: By overlapping of one panel from Figure A over one panel from Figure B, identify six different "diagrams," where each diagram has to represent one of the following cases (i.e., do not change the names of the diagrams): Diagram 1: The most economically-efficient advertising campaign. Diagram 2: The least economically-efficient advertising campaign. Diagram 3: An advertising campaign that is most efficient in promoting the product Zeta, but at the highest average cost. Diagram 4: An advertising campaign that is most cost-efficient but the least efficient in promoting product Zeta. Diagram 5: An advertising campaign is successful in shifting the demand curve of the consumers upward at the least average cost possible, but was not successful in convincing the consumers that product Zeta has fewer good substitutes, and accordingly the campaign failed to convince the consumers that product Zeta is more important to them in the long run. Diagram 6: An advertising campaign that is most efficient in promoting the product Zeta, but did not change the most productive efficient level of output in the long run (i.e., the level of output that maximized economies of scale). Third Scan each created diagram and submit all four diagrams in one PDF file. Before scanning, make sure to show (mark and shade) the equilibrium status in the long run, AFTER the advertising campaign is executed, represented by all of the following: The equilibrium market price (mark it as "P2" on the vertical axis). . The Watsonia's equilibrium level of the long-run average cost (mark it as "LAC2" on the vertical axis). The Watsonia's long-run equilibrium output (mark it as "Q*" on the horizontal axis). The long-run profit area (shade the profit area). Type on the shaded area either "Positive Profits" or "Negative Profits" depending on whether there are positive or negative profits, respectively. If there is "Zero Profits," do not type anything or shade anything. In other words, no shadings means that profits equal zero after the advertising campaign is executed. Important: Only shade the profit areas AFTER the advertising campaign is executed. Do not show (shade) the profit areas before the advertising campaign is executed
