The student has clearly stated an appropriate and specific question for the historical investigation and has selected appropriate and relevant sources for the topic. However, the student needs to improve their explanation of the relevance of the sources to the topic of the investigation and correctly identify whether the sources are primary or secondary in nature. Additionally, while the student provided a precise analysis and evaluation of the values and limitations of the origin of the two selected sources, they need to improve their understanding of the difference between the purpose and content of historical sources and correctly identify the limitations of the source's purpose and content.
