Q.2	Biodiversity loss due to deforestation can have a cascading effect on the ecosystem. Which of the following is the LEAST likely consequence of widespread species extinction?
	a) Decreased competition among surviving species.		b) Loss of pollination services, impacting plant reproduction and agricultural yields.
	c) Increase in greenhouse gas emissions due to reduced carbon sinks.		d) Disruption of the food chain, leading to imbalances in predator-prey populations.

Q.3	A rural village has limited access to electricity, relying primarily on kerosene lamps for lighting. Kerosene use has been linked to respiratory problems and indoor air pollution. The village council is considering ways to improve access to clean and reliable electricity. Which of the following would be the most effective long-term solution to address both health concerns and energy needs?
	a) Distributing more kerosene lamps with improved ventilation.		b) Providing solar-powered lighting systems to each household.
	c) Encouraging households to use candles instead of kerosene lamps.		d) Constructing additional diesel-powered generators for increased electricity.
