Q.1	You're at the grocery store and see two types of apples: organic and conventionally grown. Both look delicious. Which choice would be more sustainable?
	a) Both choices are equally sustainable; the growing methods have minimal impact on the environment.		b) Conventionally grown apples, as they are more affordable and readily available, reducing transportation emissions.
	c) Organic apples, as they often require fewer pesticides and chemicals, promoting soil health and biodiversity.		d) There is no difference in sustainability between organic and conventionally grown apples.

Q.2	A research team investigated the effects of climate change on the migration patterns of marine species. What implications can changing migration patterns have on marine ecosystems, and how might this impact human communities reliant on these species for sustenance?
	a) Altered migration patterns might disrupt food chains, affecting species abundance and diversity in marine ecosystems		b) Changing migration patterns will have no significant impact on marine ecosystems
	c) Human communities relying on these species can easily adapt to changes in migration patterns		d) Altered migration patterns will lead to increased catch and abundance of marine species, benefiting human communities

Q.3	A town located near a geothermal hotspot is exploring various uses for geothermal energy. Considering the town's needs and available resources, where could geothermal energy be most efficiently utilised?
	a) Heating residential buildings in cold climates		b) Powering portable electronic devices
	c) Fuelling vehicles for long-distance travel		d) Illuminating streetlights in urban areas

Q.4	Your once-sunny city seems shrouded in a hazy cloud of smog, especially during winter. Cars and factories are the main culprits, but everyone suffers from breathing difficulties and reduced visibility. Which air pollutants from fossil fuels are likely contributing to this smog, and how can your city combat these issues?
	a) Fine particulate matter from car dust and industrial activities traps pollutants in the air, worsening smog. Investing in public transportation and green spaces can alleviate the problem.		b) Carbon dioxide, the main greenhouse gas from fossil fuels, directly contributes to smog, and the solution lies solely in switching to renewable energy sources like solar and wind.
	c) Nitrogen dioxide and sulphur dioxide from vehicle exhausts and factory emissions combine with sunlight to form harmful smog, which can be tackled by promoting electric vehicles and stricter emission regulations.		d) Smog is primarily caused by natural phenomena like dust storms and forest fires, and the city should focus on preparing for these events rather than blaming fossil fuels.

Q.5	Hannah is researching the environmental impact of food choices. She notices that a diet high in animal products contributes significantly to greenhouse gas emissions. What dietary change could Hannah suggest to her community to reduce this impact?
	a) Promoting a solely plant-based diet to eliminate greenhouse gas emissions.		b) Encouraging the consumption of more red meat and dairy products.
	c) Suggesting an increase in processed food consumption to reduce animal product intake.		d) Advocating for a balanced diet with moderate consumption of animal products.

Q.6	Alex is reviewing a research paper on atmospheric gases. Which gases in the atmosphere contribute significantly to the greenhouse effect, aiding in climate regulation?

During their research, the scientists observed a correlation between land-based environments and the overall health of marine ecosystems. Choose an appropriate option that best reflects the importance of terrestrial ecosystems for marine life.
	a) Land-based environments have minimal impact on marine ecosystems, thus their significance is negligible.		b) Terrestrial environments act as a buffer, filtering pollutants before they reach the oceans, thus preserving marine habitats.
	c) Marine ecosystems are entirely independent of land-based environments, having no ecological connections.		d) Human activities in terrestrial ecosystems do not affect the quality of water in marine environments.
