对于B选项还是有疑问

问题如下：

Which of the following is least accurate regarding Real GDP and nominal GDP?

选项：

Real GDP is calculated relative to a base year, while nominal GDP is based on current prices.

Inflation will not change the nominal GDP when output of goods and services remains constant.

Real GDP excluded those changes simply due to the increases or decreases of money value in total output.

解释：

B is correct. Nominal GDP is based on current prices. It does not remove the effect of price changes. Thus inflation will increase the nominal GDP when output of goods and services remains constant.

考点：

解析：名义GDP以当前价格为基础。它不排除价格变化的影响。因此，当商品和服务的产出保持不变时，通货膨胀将增加名义GDP。所以B选项入选。

名义GDP以当前价格为基础，实际GDP以基期价格为基础，所以A选项不入选。

实际GDP剔除了通胀改变带来的影响，所以C选项不入选。
