Evaluate the impact of systems of exchange on two indigenous societies.

The question requires that candidates make an appraisal of the impact of systems of exchange in two indigenous societies, weighing up their strengths and limitations. A comparative approach between the two systems of exchange may or may not be used. The two indigenous societies may or may not have been contemporaneous with each other. The impact may extend beyond the timeframe, but must be clearly linked to the issue raised in the question. Candidates may offer equal coverage of both societies, or they may prioritize their evaluation of one of them. However, two societies will feature in their response. Candidates may evaluate the contribution of the systems of exchange to labour specialization, developments in urbanization or in transport. Both strengths and limitations must be clearly indicated, but there does not need to be equal focus on each. While other relevant factors, for example the relationship between systems of exchange and territorial expansion, may be referred to, the bulk of the response will remain on the issue raised in the question.
