Use the following production possibilities frontier for a country to answer the following questions. Which point(s) are unatfainable? Briefly explain why. Point E because it is inside the production possibilities frontier. Points B, C, and D because they are on the production possibilities frontier. Point A because it is outside the production possibilities frontier. All the points because the production of each has an opportunity cost. None of the points because they all are feasible.

Point A represents an unattainable production level because it lies outside the production possibilities frontier (PPF). This point indicates that the country does not have the resources or technology to produce that combination of goods. In essence, the PPF illustrates the maximum output achievable, so any point beyond that boundary is simply not feasible. On the other hand, point E is attainable but inefficient as it sits inside the PPF. This implies that the country is not using its resources to their fullest potential. While it's possible to produce at this point, it means there are opportunities to increase production and improve efficiency without sacrificing the output of other goods. So, both points A and E highlight important concepts about production efficiency and resource utilization.
