In the scenario described, where people become pessimistic about the future due to corporate scandals, international tensions, and loss of confidence in policymakers, we can analyze the likely short-run effects on the price level and real GDP.
Pessimism typically leads consumers and businesses to decrease their spending and investment, which results in a decrease in aggregate demand. When aggregate demand decreases, this tends to lower the price level and reduce real GDP in the short run.
Given that analysis, the correct answer would be:
c. Both the price level and real GDP fall.
