To determine which points represent efficient production in Figure 2-5, we would typically look for points that lie along the production possibility frontier (PPF). Points on the frontier indicate maximum efficiency, where resources are utilized fully.
If the question provided by Figure 2-5 shows a PPF and different points (A, B, C, D) plotted in relation to it, we can infer the following:
- Points located on the PPF curve indicate efficient production.
- Points inside the curve indicate inefficient use of resources.
- Points outside the curve are unattainable given current resources.
Assuming the typical scenario where A, B, C, and D refer to various points on or off the PPF:
- If A, B, and C lie on the frontier, they represent efficient production.
- If D lies inside the frontier, it is inefficient.
Based on this logic, if the options provided are:
a. A, B, C
b. A, B, D
c. A, B
d. C
The correct answer would likely be a. A, B, C assuming A, B, and C are on the PPF, reflecting efficient production. If you have a specific diagram or additional context, please provide it for a more accurate assessment.
