This exam-style task requires a developed historical argument rather than a list of facts. Begin with the relevant period from Paper 2 Section A: Thematic studies, then anchor the answer in Part three: A revolution in medicine. The evidence should connect to Study the development of Germ Theory and its impact on disease treatment in Britain, including Pasteur, Robert Koch, microbe hunting, vaccination, Paul and be explained through cause, consequence, change, continuity, significance or interpretation as appropriate. A strong final judgement shows why the selected evidence is more convincing than a vague or unsupported claim.
