Data also shows a connection between rising global temperatures and the accelerated melting of glaciers worldwide. Considering the scenario, which of the following is the most likely consequence of the glacier's retreat for the communities downstream?
	a) Increased hydropower generation due to higher water flow		b) Improved water quality
	c) Enhanced biodiversity in the surrounding ecosystem due to the release of nutrients		d) Water scarcity and competition for resources among communities

Q.2	A local environmental agency is tasked with evaluating the water quality of a river that runs through a town. The river serves as a primary source of drinking water, recreational activities, and supports aquatic life. Concerns have been raised about the river's health due to changes in its appearance and reports of fish mortality. Please select the most appropriate answer that reflects the main categories relevant to evaluating the river's water quality.
	a) Point source, non-point source, and groundwater		b) Organic, inorganic and synthetic parameters
