Q.1	You've been tasked with organising a community waste management initiative. While researching the potential hazards of various types of waste, you discover the significant threat posed by e-waste to the environment. Based on this information, what is the primary reason why e-waste poses such a significant threat?
	a) Its rapid generation rate exceeds our ability to recycle it efficiently.		b) It contains toxic materials that leach into the environment when improperly disposed of.
	c) It takes up valuable landfill space, hindering other waste management strategies.		d) It contributes to the formation of ozone layer depletion, intensifying climate change.

Q.2	You are a farmer in a region with a temperate climate. You have been farming for over 20 years and have a good understanding of the growing cycles of your crops that have a narrow range of temperature tolerance. You have been keeping detailed records of your annual average temperature for the past decade. The graph below shows a clear trend in temperature change. Based on your knowledge of agriculture and environmental science, which of the following is the most likely impact of the observed temperature increase on your crops? A. Increased crop resilience and improved harvests. B. Reduced yield and delayed harvest C. Increased susceptibility to pests and diseases D. Optimal conditions for crop pollination and seed germination.
	a) B only		b) A and B only
	c) B and C only		d) B, C and D only

Q.3	A city is experiencing water scarcity due to changing precipitation patterns caused by climate change. What practical strategies could the city adopt to address this issue and ensure water availability for its residents?
	a) Investing in water conservation and harvesting technologies		b) Implement a stringent water rationing system to limit household water consumption.
	c) Increasing water tariffs for residents		d) Relocating residents to areas with better water sources

Q.4	In an experiment studying the effectiveness of marine protected areas, researchers compared fish populations inside and outside the protected zones. What result would indicate the success of marine protected areas in promoting fish populations?
