Twelve years ago and again five years ago, there were extended periods when the darfir republic's currency, the pundra, was weak: its value was unusually low relative to the world's most stable currencies. both times a weak pundra made darfir's manufactured products a bargain on world markets, and darfir's exports were up substantially. now some politicians are saying that, in order to cause another similarly sized increase in exports, the government should allow the pundra to become weak again.
which of the following, if true, provides the government with the strongest grounds to doubt that the politicians' recommendation, if followed, will achieve its aim?
(a) several of the politicians now recommending that the pundra be allowed to become weak made that same recommendation before each of the last two periods of currency weakness.
(b) after several decades of operating well below peak capacity, darfir's manufacturing sector is now operating at near-peak levels.
(c) the economy of a country experiencing a rise in exports will become healthier only if the country's currency is strong or the rise in exports is significant.
(d) those countries whose manufactured products compete with darfir's on the world market all currently have stable currencies.
(e) a sharp improvement in the efficiency of darfir's manufacturing plants would make darfir's products a bargain on world markets even without any weakening of the pundra relative to other currencies.

marginal cost is a microeconomic measure that us to evaluate the extent to which the level of production of a good is sustainable in accounting, that is, to how many quantities the company plans to profit from the production of the good.

the concept of marginal cost is simple, it means the cost of producing one more item. for example, in the case of pies, the marginal cost is the cost of producing one more pie than those that have already been produced.

it is important to understand that productive activity influences marginal cost. the marginal cost of some goods can be very high, while others may be insignificant. for example, the marginal cost of producing an extra plane is very high. already the marginal cost of a water company to provide 1l more water is derisory.

in the case of pies, the cost involves the inputs, the labor and the fixed cost, which involves the fixed space of the bakery. the level of production initially has the marginal cost decreasing because there is space and manpower available. however, to produce more you have to hire more workers and buy more inputs. if physical space is limited, workers will conflict with places, inputs and their productivity will decrease, meaning there is an optimum point of production for each level of space and manpower. from this point on, the productivity of the workers will be getting smaller because of lack of space, so that the marginal cost of producing one more pie will be increasing. so, although you have not posted the chart, but if you have the answer, you can see that my explanation goes according to the marginal cost curve that will increase from the 4th pie, answer (c).
