to reduce the force needed to lift the box and change the direction of the force

to reduce the force needed to lift the box while keeping the direction of the force the same
to reduce the force needed to lift the box while keeping the direction of the force the same

to reduce the energy needed to lift the box while keeping the direction of the force the same

Answer 1

to reduce the force needed to lift the box and change the direction of the force

Explanation: a lever gives mechanical advantage (less input force over a greater distance) and can reverse the direction of the applied force; it does not reduce the work (energy) required ignoring friction.
