The student's work is based on one of the 35 prompts released by the IBO for the examination session, specifically the prompt "How can we know that current knowledge is an improvement upon past knowledge?" The Exhibition consists of three objects presented alongside a commentary with a total word count not exceeding 950 words. The three objects have been clearly identified and are all pre-existing, not created for the purpose of the Exhibition. However, the real-life context of each object and the connection between the chosen prompt and each object need further clarification to meet the requirements of the task. The student should also ensure that the commentary is specific to each object rather than generic in order to effectively explore the prompt.
