39. A wine storage system uses a control device that measures the wine cell temperature T (measured in °C, rounded to the nearest degree) and alarms the user if it deviates from the optimal value of 12, according to the following rules:

• if T < 12, the system says, “temperature is too low!”

• if T > 12, the system says, “temperature is too high!”
