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	A conservationist is concerned about the declining population of a particular endangered species in a forest reserve. What would be the most appropriate action to conserve this species?
	a) Introducing a different species to the reserve to enhance biodiversity.		b) Removing some competing species to give the endangered species more resources.
	c) Conducting habitat restoration and protection efforts specific to the species' needs.		d) Keeping the endangered species safe in captivity.

Q.3	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.4	A group of researchers is discussing the causes and effects of climate change during a conference. They aim to pinpoint the accurate relationship between a specific human activity and its consequent impact on the environment. Which scenario correctly identifies a human activity and its corresponding impact on the environment?
	a) Increased usage of solar energy leading to ozone layer depletion.		b) Deforestation resulting in the loss of biodiversity and disruption of ecosystems.
	c) Reduced use of fossil fuels causing an increase in air pollution and smog formation.		d) Expansion of agricultural practices leading to a rise in sea levels and coastal erosion.

Q.5	Javier studied the adaptations of desert organisms. He discovered that certain desert plants have shallow roots but spread extensively. What advantage do these shallow, widespread roots offer to desert plants?
	a) Improved access to underground water sources.		b) Protection from extreme heat and sunlight.
	c) Enhanced stability in sandy soil.		d) Reduced reliance on photosynthesis for survival.

Q.6	A group of students in a science class is conducting an experiment to demonstrate the heat-trapping properties of greenhouse gases for a school project. They want to create a compelling demonstration. Which experimental approach should they choose?
	a) Burning fossil fuels in an open space		b) Comparing the absorption of infrared radiation by different gases

Q.8	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.9	At a science camp, Mia learns about solar energy. She analyses data and finds that a solar panel generates an average of 1.5 kilowatt-hours (kWh) of electricity per day.

Q.10	In a disaster-stricken area where access to clean water is limited, a relief organisation assists a local community facing water contamination. The primary water source, a nearby river, has been contaminated by industrial waste, rendering it unsafe for consumption.
