I need to answer the question, so could you give me an example of the question? I want to compare with your idea to answer the question.

What is (just) one specific example of how Gross Domestic Product (G.D.P.) is likely to decrease in the U.S. during this calendar year (2020)?

I need to demonstrate how (just) one of the components of the "Expenditures Approach" could decrease, and thereby make the total measured output of the country lower.
