The student did not clearly state an appropriate and specific question for the historical investigation, as the research question is too broad and lacks focus on particular laws or policies. Additionally, the question lacks a defined scope regarding key dates and significant historical events, which could be improved by narrowing the timeframe of Nazi eugenics. While the student explained the relevance of the sources to the investigation, they failed to classify the sources as primary or secondary, which is essential for assessing their reliability. Furthermore, the student did not provide a precise analysis of the values and limitations of the sources' origin, purpose, or content, which would enhance the critical evaluation of the chosen materials. Overall, these shortcomings indicate a need for greater specificity and depth in the research question and source analysis.
