Answer 2

Public service[1] is a service intended to serve all members of a community.[2] It is usually provided by the government to people living within its jurisdiction, either directly (through the public sector) or by financing provision of services. The term is associated with a social consensus (usually expressed through democratic elections) that certain services should be available to all, regardless of income, physical ability or mental acuity. Examples of such services include the fire brigade, police, air force, and paramedics. (See also: Public service broadcasting)

Even where public services are neither publicly provided nor publicly financed, for social and political reasons they are usually subject to regulation going beyond that applying to most economic sectors. Public policy,[3] when made in the public's interest and motivations, can provide public services.
