Below is a country’s PPF.

i. Does this country’s economy have the resources (land, labor, capital) to produce a combination of 3 capital goods and 1 consumer, good?

ii. does this country’s economy have the resources (land, labor, capital) to produce a combination of 2 capital goods and 7 consumer goods?

iii. does this country’s economy have the resources (land, labor, capital) to produce 4 capital goods and 6 consumer goods?

iv. if this country uses its resources to produce at production point B, would this be an efficient use of its resources?

It seems like you've mentioned a Production Possibility Frontier (PPF) for a country, which represents the maximum output combinations of two goods that an economy can produce, given its level of technology and resources.

To answer the questions, we need to look at the PPF and consider the points mentioned:

i. Combination of 3 capital goods and 1 consumer good:

Look at the PPF and check if the point representing 3 capital goods and 1 consumer good is inside or on the frontier. If it is inside, it is feasible; if on the frontier, it is possible but represents full resource utilization.

ii. Combination of 2 capital goods and 7 consumer goods:

Similar to the first question, check if the point representing 2 capital goods and 7 consumer goods is inside or on the PPF.

iii. Combination of 4 capital goods and 6 consumer goods:

Again, examine the PPF to see if the point representing 4 capital goods and 6 consumer goods is inside or on the frontier.

iv. Efficient use of resources at production point B:

To determine efficiency, check if point B is on the PPF. If it is on the PPF, it indicates an efficient use of resources. If inside, it suggests that resources are underutilized, and if outside, it implies an unattainable level of production with current resources.

Without the specific details of the PPF graph or its numerical values, I can't provide a specific answer. However, analyzing the PPF and comparing the points mentioned to the frontier will help you determine the feasibility and efficiency of the specified production combinations.
