Question

Given stable aggregate supply, which of the following changes in aggregate demand is most likely to cause economic expansion?

选项：

A.An increase in corporate income tax

B.An increase in foreign currency per unit of domestic currency

C.An increase in capacity utilization

解释：

C is correct. An increase in capacity utilization will cause an increase in aggregate demand through higher investment and will increase GDP (economic expansion).

A is incorrect. A decrease, not an increase, in corporate income tax will cause an increase in aggregate demand through higher investment and increase GDP (economic expansion).

B is incorrect. A decrease, not an increase, in exchange rate (foreign currency per unit domestic currency) will cause an increase in aggregate demand through higher exports with lower imports and increase GDP (economic expansion).

中文解析：

C正确。产能利用率的提高将通过增加投资导致总需求的增加，并将增加GDP(经济扩张)。

A不正确。企业所得税的减少而不是增加，将通过增加投资和增加GDP(经济扩张)来增加总需求。

B不正确。如果汇率(每一本币兑换的外币)下降而不是上升，就会导致出口增加，进口减少，从而增加总需求，从而增加国内生产总值(GDP)(经济扩张)。
