    Answer:

                      (a) No, I do not agree with Ram Singh.         (1) (b) There might be deficiency of iodine in food of the village children. As iodine is necessary for the thyroid glands to make thyroxine hormone. Thyroxine helps in regulating carbohydrate, protein and fat metabolism in the body to give best balance of growth.
