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	An experiment is conducted to compare the efficiency of different rainwater harvesting systems in a specific location. System A uses rooftop collection, while System B utilises surface runoff collection. Which system is likely to yield more water in an area with infrequent but heavy rainfall?
	a) System A		b) System B
	c) Both systems will yield similar amounts of water		d) None of the systems will be effective in heavy rainfall conditions

Q.3	You want to reduce your household food waste, a major contributor to greenhouse gas emissions. Which practical approach is most effective? 1. Compost all food scraps, even meat and dairy, reducing landfill waste. 2. Plan meals meticulously and buy only what you need to avoid buying and discarding excess food. 3. Store food properly to extend shelf life and prevent spoilage.
	a) Only 1		b) Only 1 and 2
	c) Only 2 and 3		d) 1, 2 and 3

Q.4	Two islands in the Pacific Ocean experience similar climates but have different levels of deforestation. Island A has lost 80% of its original forest cover, while Island B has maintained 90% of its forest. Over the past decade, Island A has experienced more frequent and intense heat waves compared to Island B. Which of the following is the most likely explanation for this difference?
	a) Island B benefits from cooler ocean currents that moderate its climate, while Island A does not.		b) Island A's proximity to volcanic activity contributes to increased heatwaves.
	c) Island A has a higher concentration of greenhouse gases in its atmosphere due to reduced carbon sequestration by forests.		d) Island B's higher elevation reduces the likelihood of extreme heatwaves.

Q.5	Researchers conducted an experiment to assess the impact of ocean acidification on marine snail populations. They exposed snails to different pH levels in controlled environments and measured their growth rates over time. The graph below illustrates the relationship between pH levels, carbonate ion concentration. Based on this data, what is the probable outcome for marine snail populations as the H+ increases in the seawater?

Q.6	Consider the case study given below and answer the following question: Case Study: The Müller Family's Journey to Renewable Energy The Müller family, residing in a charming village in the German countryside, had always been conscious about their environmental impact. In 2022, they decided to take an active step towards a greener lifestyle by installing a rooftop solar panel system. Their primary motivation was to reduce their reliance on fossil fuels and contribute to mitigating climate change. However, as they embarked on this journey, they discovered a plethora of other benefits: Environmental Benefits: -Reduced Carbon Footprint: The solar panels generated clean energy, leading to a significant reduction in their carbon emissions. This translated to a cleaner environment for their family, their community, and the planet. -Improved Air Quality: By relying less on fossil fuels, the Müllers contributed to cleaner air in their region, which improved their overall health and well-being. Financial Benefits: -Reduced Electricity Bills: The solar panels generate enough electricity to cover a significant portion of their household energy needs, resulting in substantial savings on their monthly electricity bills. This provided them with financial stability and freed up resources for other expenses. -Government Incentives: The German government offers various financial incentives for individuals and families adopting renewable energy solutions. The Müllers took advantage of these incentives, further reducing the cost of their solar panel system and accelerating their return on investment. Lifestyle Benefits: -Energy Independence: The Müllers achieved a sense of energy independence by generating their own clean energy. This gave them greater control over their energy consumption and reduced their dependence on the national grid, especially during peak hours. -Enhanced Home Value: Homes with renewable energy systems are becoming increasingly sought-after, leading to a potential increase in the value of the Müller's property. Overall Impact: The Müller family's experience showcases the numerous benefits of adopting renewable energy in a domestic setting. Their commitment to environmental sustainability not only helped them create a cleaner future but also resulted in financial savings and enhanced their quality of life. Their story serves as an inspiration for others to consider switching to renewable energy and contribute to a more sustainable future. The Müller family experienced a change in their lifestyle that resulted in increased energy consumption. Which of the following strategies could they implement to maintain their energy independence? A. Install additional solar panels to increase energy generation. B. Utilise a battery storage system more efficiently. C. Increase their reliance on the national grid. D. Install additional solar panels to increase energy generation.
