Answer

Brief Explanations:

A lever is a simple machine. In construction, levers like crow - bars are used to lift weights by applying a force at one end to move a load at the other. In astronomy, other instruments are used to track stars. In medicine, surgical tools are more specialized and not simple levers in the traditional sense. In literary courses, levers are not used to explain ideas. And for transporting water, pumps and pipelines are more common than levers.
