The USDepartment of Agriculture's Extension Services, with Its Local "Extension Agents

The U.S.Department of Agriculture's Extension Services, with its local "extension agents" who consult with farmers to promote farm productivity, provides a familiar example of:

A) the devolution of government service, from the national to the local level, in order to shrink government.
B) how many of the personnel in clientele agencies' field offices or operations deal directly with clientele.
C) the way that Congress provides jobs through "pork barrel" spending for particular district or state constituencies.
D) how clientele agencies come to lobby for policy change at the local or grassroots level.
