An economist has presented a report on backward areas stating that the backward regions have ample opportunities for their economic development if proper industries are established by the entrepreneurs looking into the availability of local resources. the unskilled and uneducated workforce can be employed in farming, mining, lumbering industries.
the villagers of such areas can have cattle breeding farms and poultry farms as additional source of income other than farming. the roads, dams etc can be constructed to develop infrastructure. banking, warehousing, transportation, communication etc to be developed adequately to support the rapid industrialization in such areas.
(a) list the different types of industries mentioned in the report.
(b) explain the different types of secondary industries.

a) The industry is divided into four sectors: primary, secondary, tertiary and quaternary. Of the industries named in the report, we can identify:

- primary - farming, mining, lumbering (since they are associated with collecting the raw materials)

- secondary - construction (involved in the production of a good using raw materials)

- tertiary - banking, warehousing, transportation (providing services)

- quaternary - telecommunication

b) The report listed the construction industry (making roads, dams...) as the secondary industry. Industries in this sector transform raw materials into goods or are simply involved in construction, which is a special kind of finished good (infrastructure).

It is often divided into light and heavy industry. Light industry requires less capital for equipment, and makes goods primarily for the end user (for example, FMCG industries), while the heavy industry involves big plants and facilities and complicated industry processes.
