Q.1	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.2	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.3	A community introduced a new technology that reduced water usage for irrigation by 20%. Initially, 1,000 hectares of land were irrigated using 200,000 cubic meters of water. What volume of water would be saved annually if this technology is applied to all 1,000 hectares?
	a) 40,000 cubic meters		b) 20,000 cubic meters
	c) 160,000 cubic meters		d) 250,000 cubic meters

Q.4	In a remote village, access to electricity is limited. The government aims to introduce affordable and clean energy sources to improve living conditions. Considering the village's geographical isolation, unreliable grid connections, and the need for sustainable solutions, which approach would be the most effective and practical for providing immediate access to clean energy?
	a) Establishing a small-scale wind turbine farm to harness local wind resources.		b) Implementing solar microgrids tailored to the village's energy needs.
	c) Introducing biogas digesters to convert organic waste into usable energy.		d) Installing small-scale hydroelectric systems using nearby streams or rivers.

Q.5	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.6	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.7	Daniel's school initiated a project to implement bioenergy sources to reduce its carbon footprint. As part of their research, they explored various options for renewable bioenergy. They considered using different materials such as agricultural waste, wood chips, and animal manure. Which of the following materials can be considered a renewable source of bioenergy?
	a) Coal briquettes		b) Plastic waste from the school cafeteria
	c) Wood chips from sustainably managed forests		d) Food waste from the school cafeteria burned in an incinerator

	a) Ionosphere		b) Exosphere
	c) Troposphere		d) Stratosphere

Q.9	A farmer observed that the soil in his fields was becoming increasingly dry, even after heavy rainfall. The farmer suspected that the dry soil was due to increased runoff, preventing water from infiltrating the ground. Which of the following practices could help the farmer improve soil moisture? A. Tilling the soil to increase its water-holding capacity B. Planting cover crops to protect the soil from erosion C. Creating channels and other structures to slow down runoff
	a) A only		b) A and B only
	c) B and C only		d) A, B and C

Q.10	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.
