Answer:
Situation: Water is liquid at 40°C above zero and it turns to ice at below zero temperatures. For example, water at 19°C below zero is frozen.
Step-by-step explanation:

The integer that represents 40°C above zero is 40.
The attached number line shows that 40 is at the right of -19. So -19 < 40.
