问题如下：
If a country’s GDP decreases, which of the following conditions is unlikely to be the reason?
选项：
A.
domestic investment decreased.
B.
net exports decreased.
C.
government transfer payments decreased.
解释：
C is correct.
Government transfer payments are not included in GDP.
考点：转移支付
解析：转移支付不属于GDP的构成成分，它是在计算national income时才需要考虑的组成部分。
A,B选项都是支出法下GDP的组成成分。它们的下降会引起GDP的下降。
老师请问national income怎么算？
