Evaluate the economic impact of the First World War on two countries of the Americas.

The question requires that candidates make an appraisal of the economic impact of the First World War on two countries of the Americas. A comparative approach may or may not be used. The impact may extend beyond the timeframe, but it must be clearly linked to the issue raised in the question. The question does not require that the countries chosen were involved militarily, though they certainly could have been. Likely choices are the United States, Canada and Brazil, but accept any other relevant country for which an economic impact can be shown. Candidates may refer to industrial growth in war industries, agricultural expansion and increased sales. If the chosen country entered the war, candidates are likely to discuss the economic growth as a result of increased wartime spending. Candidates may offer equal coverage of the two countries or they may prioritize their evaluation of economic impact on one.
