问题如下：
If the domestic currency becomes stronger compared to foreign currency, then:
选项：
A.aggregate supply curve will shift downward.
B.aggregate demand curve will shift downward
C.aggregate demand curve does not change.
解释：
B is correct. The stronger domestic currency will result in a decrease in net export, so the short run aggregate demand will decrease and the SRAD curve will shift downward, the short run aggregate supply curve will increase and the SRAS curve will shift upward.
考点：短期总需求总供给曲线
解析：本币走强，净出口下降，短期总需求下降，AD曲线向下平移，所以B选项正确，C选项错误。
本币走强后进口原材料价格以本币计量数值下降，那么短期总供给曲线上升，SRAS曲线向上平移。所以A选项错误。
老师，好：
这道题目看了前面的提问。确实AB都是对的哇。所以说考试不会出这种模棱两可的题目吧？
