Q.1	In a local community initiative, Sarah's school decided to promote recycling. They collected plastic bottles, newspapers, and aluminium cans. What's the primary advantage of recycling these materials?
	a) Reducing landfill space and environmental pollution.		b) Increasing the cost of production for new materials.
	c) Promoting the use of non-renewable resources.		d) Decreasing the need for waste segregation.

Q.2	In an area facing increased soil erosion due to extreme weather events linked to climate change, farmers seek strategies to protect soil health. What practice aligns best with sustainable soil management in such conditions?
	a) Clearing land for larger-scale monoculture to simplify farming practices.		b) Implementing agroforestry systems to prevent soil erosion and maintain fertility.
	c) Relinquishing organic matter addition to soil for fear of further erosion.		d) Applying chemical pesticides extensively to eradicate soil-dwelling pests.

Q.3	The government of a city wants to switch to renewable energy sources to help the environment. Which of the following strategies could the city use to promote renewable energy adoption and reduce environmental impact?
	a) Implementing tax incentives for solar energy installations		b) Developing new coal mining projects to boost energy production
	c) Encouraging the use of gasoline-powered vehicles		d) Cutting down more trees to make space for wind farms

Q.4	A family decides to install solar panels on their roof to generate electricity. How does this contribute to responsible energy consumption?
	a) Increases carbon emissions and environmental impact		b) Reduces reliance on non-renewable energy sources such as fossil fuels
	c) Promotes excessive energy consumption and wastage		d) Encourages dependence on unsustainable energy practices

Q.5	Imagine you are an urban farmer in a city with limited space. Which farming method would be most suitable for your situation?
	a) Large-scale traditional farming		b) Vertical farming
	c) Expansive greenhouse farming		d) Aquaculture in open ponds

Q.6	A group of scientists is studying the effects of climate change on a mountain grassland ecosystem. They observe that the average temperature in the region has increased over the past few decades, and that the timing of plant flowering has shifted earlier in the spring. How might these changes impact the interactions between plants and pollinators in this ecosystem?
	a) Pollinators may have difficulty finding food sources due to the mismatch between their life cycle and the timing of plant flowering, also resulting in reduced pollination success.		b) Pollinators may benefit from the increased temperature, as it could lead to an increase in plant growth and nectar production.
	c) Earlier plant flowering may have no significant impact on pollinators as they can adapt their behaviour and life cycles accordingly.		d) The rise in temperature could decrease the number of plant species, thereby reducing the variety of resources available for pollinators, causing a decline in their populations.

Q.7	At Greenway Middle School, the cafeteria decided to track food waste over a week. The given table represents the daily amount of food wasted. If the school wants to reduce food waste by 20%, how much food, in kilograms, should they aim to save each day?
