The correct response regarding what is accomplished by a simple pulley is: It changes the direction of the force needed to lift the object.
A simple pulley allows you to pull down on a rope to lift an object upwards, which can make lifting easier in certain situations, but it does not change the amount of work done or the distance needed to lift the object.
