Question
[116]. Passage: Cities can be several degrees hotter than surrounding countryside because concrete and asphalt absorb heat, vegetation is scarce, and waste heat from vehicles and air conditioners accumulates. Night brings little relief when buildings radiate stored heat, endangering elderly residents and outdoor workers. Planting trees, preserving water bodies, using reflective roofs and designing ventilation corridors can lower temperatures, but isolated parks help little if surrounding streets remain sealed. Cooling a city is therefore a matter of connected green and blue networks, not of a few decorative plots. The word 'radiate' in the passage most nearly means:
