Q.1	Which of the following statements describes the role of zoos in endangered species conservation? 1. Zoos primarily exist for entertainment purposes and have no impact on conservation efforts. 2. Zoos serve as a means to display animals but have little involvement in conservation initiatives. 3. Zoos play a significant role in conservation by housing and breeding endangered species. 4. Zoos contribute to the endangerment of species by removing them from their natural habitats.
	a) Only 1		b) Only 2
	c) Both 1 and 3		d) Only 3

Q.2	Robert, an environmentally conscious individual, has recently initiated a practice of composting her food scraps and yard trimmings. He intends to utilise the resultant compost as soil enrichment for her garden beds, aiming to reduce dependency on commercial fertilisers and promote sustainable gardening practices. Considering Robert's endeavour to compost his organic waste and repurpose it for his garden, which sustainable practice does his action primarily demonstrate?
	a) Reduce		b) Recycle
	c) Source reduction		d) Reuse

Q.3	Your city throws away tons of food, leading to environmental issues and wasted resources. Two groups proposed solutions: Group A: "Community Kitchens": Establish kitchens that collect discarded food, prepare nutritious meals, and serve them to those facing hunger. "Urban Composting Network": Create a network of community composting bins and educational programs to turn food scraps into nutrient-rich soil for urban gardens. Group B: "Smart Fridges": Implement high-tech fridges that monitor food freshness and notify owners to prevent expired waste. "Automated Recycling Plants": Build specialised plants that efficiently process organic waste into fertilisers and renewable energy. Which group's approach do you think will more effectively reduce food waste and address related challenges? Why?
	a) Group A, because their solutions directly tackle hunger and soil depletion while utilising waste.		b) Group B, because their solutions focus on prevention and technological efficiency.
	c) Neither group, as existing policies are sufficient to address food waste issues.		d) Both groups offer complementary solutions, combining social impact with waste reduction and resource utilisation.

Q.4	A family decides to install solar panels on their roof to generate electricity. How does this contribute to responsible energy consumption?
