Answer 1

The ramp reduces the mechanical force needed to move the refrigerator.

Explanation: By using the ramp the movers apply a smaller force over a longer distance (the force component along the ramp is less than lifting straight up), making it easier to get the refrigerator up the 6‑inch step.
