Answer:
1. shut down;
2. a decrease in the quantity of real GDP supplied
Explanation:
The price level is finance or business term that describes the general price of the cost of commodities; this includes products and services in an economy at a given period.
Hence, in a situation whereby the price level falls and the money wage rate does not change, some firms have to SHUT DOWN and which in turn will lead to "a decrease in the quantity of real Gross Domestic Product supplied."
