Solution

There are two types of infrastructure: (a) economic infrastructure,(b) social infrastructure.Economic infrastructure directly supports the economic system from inside. Examples are energy, transport and communication. Social infrastructure indirectly supports the economic system from outside. Examples are health, education and housing.Economic and social infrastructure are complementary to each other. Economic infrastructure improves the qualityof economic resources and raises the production, but it cannot be possible until population is literate to use them efficiently. Thus, both of them are needed for the growth and development of the country.
