Answer 1

In levers, Class 2 levers can be used to increase the force that must be applied. This class of lever has the load in the middle, allowing you to apply a smaller force to lift a larger load. Therefore, the correct response would be Class 2 and 3, as Class 2 lever can increase force, while Class 3 lever typically requires more force to move a load, but they don't increase force in the same way.

So, the best answer is Class 2 and 3.
