Q.8	Consider the case study given below and answer the following question: Case Study: Water Conservation in Singapore Singapore, a water-scarce nation, implemented innovative strategies for water conservation and efficient use. One notable initiative is the "NEWater" program, where wastewater is treated extensively to produce high-grade reclaimed water. This reclaimed water is then used for industrial processes, cooling systems, and even direct consumption after rigorous purification. Additionally, Singapore employs an extensive rainwater harvesting system, collecting rainwater on a large scale for non-potable uses like flushing toilets and watering plants. These initiatives have not only reduced the strain on the city-state's water supply but also ensured sustainable water management for the growing population. What challenges does Singapore addressed by implementing these water conservation initiatives?
	a) Controlling air pollution and promoting soil erosion		b) Preventing excessive flooding and reducing industrial water demand
	c) Alleviating water scarcity		d) Increasing potable water usage

Q.9	A city planner is entrusted with developing a climate adaptation plan for their municipality.
