Explanation Preview
The passage begins by introducing the topic of green roofs for cooling and quickly focuses on the 'more advanced and pressing question' of their 'collective influence on the wider urban microclimate' (Paragraph A). It then explores the mechanisms, types, influencing factors (like urban geometry and plant choice), and policy requirements for achieving this district-level cooling, consistently maintaining this specific focus. The other options are too narrow or not supported by the overall content.
