问题如下：
Which of the following best describes nominal GDP?
选项：
A. it is a measure of total expenditures at current prices.
B. it is a measure of total expenditures at base prices.
C. it is a measure of total value of goods and services at base prices.
解释：
A is correct.
According to definition, nominal GDP is the total value of all goods and services produced by an economy valued at current market prices. Because aggregate expenditures must equal to aggregate output of an economy, which is as same as the total value of goods and services.
考点：GDP定义
解析：注意到GDP的衡量使用当期的市场价值而非基期的价值，所以本题只有A选项符合条件。
不知道为什么选这个选项
