The correct response is:
when the shovel is in the dirt and you push down against the end of the shovel, making it pivot.
In this scenario, the shovel acts as a lever where the point of contact with the ground serves as the fulcrum, and the force applied at the end of the shovel allows for lifting the dirt.
