A hydraulic jack performs the task of moving objects by ____.
utilizing oil; because oil cannot be compressed, pressure is placed upon the oil, resulting in a lifting motion
using a pulley system to lift items
using a corkscrew-like effect to function
pressing together two interfacing parts to increase height
Detailed Explanation
The use of oil is the only answer that accurately describes the motion and mechanics of hydraulic jacks. Though the other answers correctly describe the purpose of a jack (to increase height), they do not mention oil or compression in the function of a jack.
