Answer 1

a) Food is necessary for the growth and development of the body. Balanced diet provides raw materials and energy in the appropriate amount needed, like protein, carbohydrates, fats, minerals, etc,which in turn are essential for the proper growth and functioning of a healthy body.

b) Health is a state of well-being to function physically, mentally and socially well and these conditions depend upon the surrounding environmental conditions eg., if there are unhygenic conditions in surrounding areas, it is likely that we might get affected or suffer from diseases.

c) Our surrounding area should be free of stagnant water. This is so, because many water-borne diseases and insect vectors flourish in stagnant water which causes diseases in human beings.

d) Human beings live in socities and different localities like villages or cities which determine social and physical environment and hence, both are to be kept in harmony. Public cleanliness is important for individual health. For better living conditions, a lot of money is required. We need good food for a healthy body and for this we need to earn more. For the treatment of diseases also, one's economic condition has to be strong.
