Which one of the following is not an example of infrastructure in a country?

Correct answer: (a) Private houses

Explanation

Infrastructure is the set of basic facilities and services that the economy and society share:

• economic infrastructure: transport, power, telecommunication, irrigation, water supply, banking;
• social infrastructure: schools, hospitals, sanitation and other public services.

Transportation, telecommunication and public services are all infrastructure. A private house serves only the family that owns or lives in it; it is a private asset, not a facility the economy uses in common.
