graph below. A line graph plots the number of chickens versus the number of turkeys for four parameters.A line graph plots the number of chickens, which ranges from 0 to 50 with an increment of 10, against the number of turkeys, which ranges from 0 to 50 with an increment of 10, for four parameters. The graph has two descending lines, which start at 40 chickens and end with 50 turkeys, and another line, which begins at 50 chickens and ends at 40 turkeys. Each line is connected by semi-circle arcs at the top. The highest points are labeled III and IV, and the lowest are labeled I and II. Suppose that the opportunity cost of producing 10 chickens is always 8 turkeys. Given this, the relevant production possibility curve must be: Multiple Choice I1. II2. III3. IV4
