Let's break down what happens when both nominal GDP and real GDP fall and what that implies about production and prices.
Option a: 'Price levels must increase in Country A.' This is not necessary. A rise in price levels could occur in some scenarios, but the condition that both nominal and real GDP decrease does not require prices to rise. In other words, prices could fall, stay the same, or rise, as long as real output falls enough to push nominal GDP down as well.
Option b: 'Production must decrease in Country A.' Real GDP is a measure of the quantity of goods and services produced, adjusted for price changes. If real GDP declines, it means the quantity produced has fallen, regardless of price movements. Since real GDP is tied to physical production, a drop in real GDP directly indicates reduced production levels.
Option c: 'Both price levels and production must decrease in Country A.' While production must decrease given the real GDP drop, price levels do not have to fall; they could rise, fall, or stay the same. Therefore, stating that both must decrease is too strong and not required by the given condition.
Option d: 'Price levels must decrease in Country A.' Similar to option a, there is no necessity for prices to decrease. Prices could increase or remain unchanged even if real GDP falls, depending on the relative magnitudes of price changes and output changes.
In summary, only option b aligns with the logical consequence of a decrease in real GDP: a reduction in the physical production of goods and services. The other statements impose conditions on price levels that are not compelled by the given information.
