Q.1	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.2	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. Boiling water is one known method for purifying it, but the situation requires alternative solutions due to the sheer volume of contaminated water. What additional effective method can be utilised on a larger scale to purify the contaminated water, making it suitable for drinking purposes in such an emergency?
	a) Adding calcium tablets		b) Activated carbon filtration
	c) Pouring it through a coffee filter		d) Employing a reverse osmosis filtration system

Q.3	Maya and Ethan observe vibrant coral reefs, but they notice patches of white, bleached skeletons amidst the colourful corals. Choose the MOST likely factor triggering coral bleaching.
	a) Increased nutrient runoff from coastal farms, promoting algal growth that smothers corals.		b) Overfishing by large trawlers, disrupting the food chain and reducing herbivores that control algae.
	c) Rising ocean temperatures exceeding corals' stress tolerance, causing them to expel vital symbiotic algae.		d) Increased water pollution from industrial waste, introducing toxic chemicals that directly harm coral tissues.

Q.4	You're advising a friend on reducing their ecological footprint through dietary changes. Which practical suggestion aligns best with this goal?
	a) Consuming more frozen foods for convenience.		b) Opting for seasonal, locally grown produce.
	c) Buying individually packaged snacks for portion control.		d) Choosing imported exotic fruits over locally available ones.

Q.5	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.6	During a school project on recycling, Emma was tasked with investigating the environmental benefits of recycling aluminium cans versus manufacturing new ones.
