The student's research question is clear, focused, and fully relevant to the investigation, as it includes the independent variable (intensity of land use) and the dependent variable (plant biodiversity). The environmental issue is discussed in the work, providing context for the research question, with a clear connection established between the research question and the environmental issue. However, the student should have provided a clearer explanation linking the environmental issue to the research question, specifically addressing how the significant increase in land use impacts biodiversity in Snowshill, UK to clarify the relevance of the environmental issue to the investigation.
