Q.1	During a marine conservation seminar, a panel discusses the diverse range of threats posed by ocean plastics to marine life. They emphasise the severe consequences and challenges faced by various species due to plastic pollution in oceans. Which scenario best illustrates the impact of discarded plastic on marine life?
	a) Volunteers find intact plastic bottles floating near a reef, causing minor obstructions to fish.		b) Discarded fishing nets entangle sea turtles, causing injuries and hindering their swimming.
	c) Seabirds consume small plastic debris, with unclear effects on their health.		d) Marine biologists locate scattered plastic bags on the ocean floor with minimal impact on organisms.

Q.2	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) Both groups offer complementary solutions, combining social impact with waste reduction and resource utilisation.		d) Neither group, as existing policies are sufficient to address food waste issues.

Q.3	A study in a river basin area shown in the picture reveals that the concentration of heavy metals in the water significantly exceeds permissible limits downstream of an industrial area. What can be inferred from this data?
	a) Heavy metals have no impact on water quality		b) The river basin acts as a natural filter, reducing pollution
	c) Industrial activities are likely the source of heavy metal pollution		d) The upstream area is more polluted due to urban development

Q.4	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.5	In a study assessing greenhouse gas emissions in the food production sector, researchers analysed various contributing factors. Which factor most likely contributes most significantly to greenhouse gas emissions?
	a) Land clearing for agricultural purposes		b) Fertiliser use
	c) Livestock production		d) Irrigation practices

Q.6	In a coastal region, oil spills are a common occurrence due to shipping activities. Which ecological consequence can be observed in the affected marine ecosystem?
	a) Increased biodiversity and thriving fish populations		b) Coral reefs growing rapidly to filter out oil contaminants
	c) Mass mortality of marine life and damage to habitats		d) Faster recovery of oil-impacted areas than non-impacted ones

Q.7	A country is considering expanding its nuclear energy capacity. Which of the following key environmental considerations they should address before making a decision? 1.
