问题如下：
Which of the following best describes the aggregate supply curve in the short run (e.g., 1 to 2 years)? The short-run aggregate supply curve is:选项：
A.flat because output is more flexible than prices in the short run. B.vertical because wages and other input prices fully adjust to the price level. C.upward sloping because input prices do not fully adjust to the price level in the short run.解释：
Due to long-term contracts and other rigidities, wages and other input costs do not fully adjust to changes in the price level in the short run. Given input prices, firms respond to output price changes by expanding or contracting output to maximize profit. Hence, the SRAS is upward sloping.
中文解析：
由于长期合同和其他刚性，工资和其他投入成本在短期内不能完全适应价格水平的变化。给定投入价格，企业对产出价格变化的反应是扩大或收缩产出以实现利润最大化。因此，SRAS是向上倾斜的。
