The correct advantage of a class 3 lever is:
It decreases the amount of force that needs to be applied.
Class 3 levers allow for a greater range of motion and speed at the expense of the amount of force applied, meaning that while you have to apply more distance of effort, it enables you to lift heavier loads with less direct force.
