Question and Answer


Dehydration usually develops indeep mines workers because
(A) Water is lost due to evaporation.
(B) Water is lost in the form of sweat.
(C) Water is lost along with salts from skin.
(D) Water is lost due to defecation.


Answer: C
Underground mining is hard and dangerous work, and physical exertion at such high temperatures raises body temperatures. Miners sweat profusely, During such physical work, the sweat is composed of both water and salt. As a result, the deep miners suffer from dehydration as there is loss of water along with salts from skin in the form of sweat.
Therefore, the correct answer is option C.
