Q.1	While shopping, Maya sees a new "biodegradable" label on plastic water bottles. Curious, she wonders how accurate this claim is. What should Maya be cautious about regarding the "biodegradable" label on these plastic water bottles? 1. Even if biodegradable, these bottles might not decompose quickly in home compost bins. 2. Biodegradable plastics could harm the environment in different ways if not disposed of properly. 3. This label doesn't necessarily mean the bottles are made from recycled materials.
	a) Only 1		b) Only 1 and 2
	c) Only 2 and 3		d) 1, 2 and 3

Q.2	Blair, an environmentally conscious consumer, is shopping for groceries at a local store. She notices a food product with an eco-label that states "Organic" on the packaging. Curious about its meaning, she checks the information available to understand the significance of the label. In the context of eco-labelling, what does the presence of an "Organic" label on a food product signify based on Emily's observation?
	a) The product is made using recycled materials.		b) It is manufactured using renewable energy sources.
	c) It's produced using sustainable farming methods without synthetic pesticides or fertilisers.		d) It contains natural ingredients.

Q.3	Which of the following scenarios best exemplifies a successful conservation program aiming to protect endangered marine species? 1. A fishing community that continues to use unsustainable fishing practices in a protected marine reserve. 2. A coastal city that builds a new port in a key nesting area for sea turtles. 3.A campaign that educates fishermen about the importance of using turtle-excluder devices. 4.
