Visit a village or colony located near to your residential area and note down the various activities undertaken by the people of that village or colony.
If this is not possible, ask your neighbor what is their profession? In which of the three sectors will you categories their work?
After asking my neighbors I came to know that they are indulged in different professions:
(i) Mr. Ramesh is a farmer.
(ii) Mr. Mohan Lal works in a bank.
(iii) Mr. Sumit works in a factory.
So all the three workers’ work can be categorised as Primary, Secondary and tertiary sector respectively.
