The student clearly stated an appropriate and specific question for the historical investigation, focusing on the significance of spectral evidence in the Salem Witch Trials from 1692-1693. The scope of the investigation is well-defined, including relevant historical figures and events, which grounds the analysis effectively. The student selected appropriate and relevant sources, clearly explaining their relevance to the investigation, although they did not explicitly categorize the sources as primary or secondary. The analysis of the values and limitations of the origins and content of the sources is precise, but the evaluation of the sources' purposes lacks clarity, as it does not distinctly articulate what each source aims to achieve.
