问题 In a macroeconomic model without foreign trade or government spending, aggregate demand is the sum of______.

选项 A、personal saving and private investment
B、personal saving and personal consumption
C、personal consumption and personal income
D、personal consumption and private investment

答案 D

解析答案为D项。一个经济的总需求(aggregate demand)由消费需求、投资需求、政府需求和来自于国外的需求构成。因此，假设没有国际贸易和政府支出，则总需求的构成要素只有私人的消费需求和投资需求。故本题选D项。
