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	During science class, students learned about waste separation and its significance. Which practice best aligns with responsible waste separation?
	a) Mixing plastic, paper, and glass together in the same bin for collection.		b) Composting food waste along with plastic wrappers.
	c) Discarding all waste in a single bin for easier disposal.		d) Segregating waste into different bins for recycling and composting.

Q.3	You've been tasked with managing a community composting project. Over a period of 20 days, you monitored the temperature changes within the compost pile. Based on the data depicted in the graph below, what could be the likely reason behind the observed fluctuations in temperature throughout the composting process?
	a) Insufficient aeration leading to anaerobic conditions and temperature fluctuations.		b) Adequate moisture levels causing microbial activity and temperature rise.
	c) Lack of moisture causing temperature variations as the decomposition process slows down.		d) Lack of compostable materials resulting in temperature fluctuations due to microbial imbalance.

Q.4	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.5	A community decides to implement a biomass energy system that uses organic materials to produce electricity. Which material among the following would be most suitable for this type of energy generation?
	a) Plastic waste		b) Glass bottles
	c) Agricultural residues		d) Metal scraps

Q.6	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.
