Both conflicts have led to change in the Middle East. Describe what changes happened because of U. S. Presence in the (1) Persian Gulf Conflict, (2) the invasion of Afghanistan, and (3) the invasion of Iraq. There should be THREE parts to your answer

(1) Persian Gulf Conflict - American intervention led to the survival of Kuwait as an independent country. Without the U.S., Kuwait would have probably succumbed to Iraqi aggression since Iraq is a much larger and powerful country. This intervention also weakened the regime of Saddam Hussein, the former dictator of Iraq.

(2) the invasion of Afghanistan - American intervention resulted in the removal of the Taliban from power, and the installment of a U.S. friendly government that still rules the country, officially. However, the Taliban still have de facto control over vast areas of the country.

(3) the invasion of Iraq. - American intervention resulted in the removal from power and capture of Saddam Hussein, who would be excecuted years later. However, this invasion was also a complicated matter that made the country more unstable, worsened relations between sunni muslims, shia muslims, and kurds, and paved the way for the emergence of ISIS.

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).
