Final answer:
The see-saw represents a first-class lever with the fulcrum between the effort and the load.
Step-by-step explanation:
In a see-saw, the fulcrum is the point of rotation, the effort is the force applied to make the see-saw move, and the load is the weight of the person sitting on the see-saw. Based on this, the arrangement represents a first-class lever. In a first-class lever, the fulcrum is between the effort and the load, as is the case with a see-saw.
