The student effectively incorporated relevant and appropriate source material that directly supports the research question regarding the impact of female labor-force participation on fertility rates in Rachuonyo North. The essay utilized a variety of credible sources, including academic journals, government reports, and the Kenya Demographic and Health Survey (KDHS), which strengthened the analysis. Additionally, the student employs geographic terminology accurately and maintains an academic tone throughout the essay. However, the student failed to define the term "nationally representative," which detracts from demonstrating their comprehensive understanding of the topic. Overall, the integration of resources and methods is well-executed, supporting the arguments presented.
