A Social-Impact Study Conducted by Thayer Scudder and Elizabeth Colson

A social-impact study conducted by Thayer Scudder and Elizabeth Colson in Zambia found that:

A) Nuer tribesmen could not give up herding and switch to plow agriculture without totally abandoning their religion, values, norms, mores, and political structure.
B) The medical innovations proposed by the health clinic would probably fail unless the shamans were involved in administering to the patients at the same time.
C) The forced relocation of the rural community would create extreme stress and result in people clinging to familiar traditions and institutions during the change.
D) The new highway would benefit only the elite and rich of the community, leaving the peasants in worse condition than before.
