Explanation Preview
Paragraph E states the 'oasis effect' is 'often highly localized' and that 'The cool air generated at roof level can struggle to descend... meaning the perceptible cooling benefits for citizens on the ground may be minimal'. This supports the idea that the benefits are confined to the immediate vicinity of the roof.
