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 have chosen appropriate and relevant sources for the topic of the investigation, and explained their relevance to the topic. However, they did not specify whether the sources are primary or secondary in nature. The student has provided a precise analysis and evaluation of the values and limitations of the origin and content of the two selected sources, but needs to reflect on the limitations of the second source's origin and the limitations of the first source's content to fully meet the criteria.
