The student has clearly stated an appropriate and specific question for the historical investigation, with a clearly defined scope in terms of dates, significant historical figures, and historical events. They chose relevant sources that are directly connected to the research question and explained their relevance to the investigation. Additionally, the student explained the form of the sources and provided a precise analysis and evaluation of the values and limitations of the content of both sources. However, the student needs to improve their analysis of the origins and purpose of the selected sources, as they only analyzed the value of one source and failed to critically analyze their limitations.
