The student has clearly stated an appropriate and specific question for the historical investigation, proposing the question: "How significant were the impacts of the Suez Crisis on British foreign policy?" The student has also chosen appropriate and relevant sources for the topic of the investigation, incorporating other important sources like articles from well-known journals. Additionally, the student has explained the relevance of the sources to the topic of the investigation, as well as the nature and form of the chosen sources. However, the student could improve by making the selected question more specific by adding a time-scope, and by stating whether the sources used are primary or secondary. Nevertheless, the student has provided a precise analysis and evaluation of the values and limitations of the origin, purpose, and content of the selected sources, demonstrating a strong understanding of the historical investigation process.
