Q.1	Imagine you're a conservation biologist studying the environmental impact of electronics. You're particularly concerned with the extraction of raw materials needed for manufacturing, like lithium and cobalt. Which of the following indirect consequences is likely to negatively affect ecosystems due to this mining activity?
	a) Improved ecosystem resilience		b) Increased carbon sequestration
	c) Improved connectivity in the area		d) Habitat destruction and soil degradation

Q.2	You're passionate about reducing your environmental footprint, particularly concerning packaging materials. You've come across a study that highlights the significance of recycling and reuse in lessening the environmental impact of packaging. Which of the following statements accurately reflects the environmental impact of recycling and reuse in relation to packaging materials?
	a) Recycling is always the most environmentally friendly option, regardless of the material.		b) Recycling and reuse are equally effective in reducing the environmental impact of packaging.
	c) Recycling and reuse are not effective strategies for reducing the environmental impact of packaging.		d) Reuse is generally more environmentally friendly than recycling, especially for non-recyclable materials.

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) Encouraging households to use candles instead of kerosene lamps.
	c) Providing solar-powered lighting systems to each household.		d) Constructing additional diesel-powered generators for increased electricity.

Q.4	Imagine two households, the Smiths and the Joneses, who both live in similar apartments with identical appliances like refrigerators, washing machines, and TVs.
