Energy is required in the utilisation of _____________

(a) groundwater

(b) surface water

(c) both groundwater and surface water

(d) capillary water

This question was posed to me in an interview for job.

My question comes from Factor Controlling Occurrence of Ground Water in section Ground Water for Irrigation through Wells and Tubewells of Irrigation Engineering

Answer 1

Right answer is (a) groundwater

For explanation: For irrigation purposes, groundwater is largely tapped in India through wells and tube wells. Manual, wind, diesel or electric power can be used for lifting water from open wells. The subsequent development in the technique of tapping groundwater is the use of tube wells which requires diesel or electric power.
