Q.1	A local community organises a recycling event. They provide separate collection bins for paper, plastic, glass, and electronic waste. Which of the following actions is appropriate at the event?
	a) Throwing all items in the same bin.		b) Separating and placing each type of recyclable in its designated bin.
	c) Mixing paper, plastic, glass, and electronic waste in one container.		d) Ignoring the event and leaving recyclables at home.

Q.2	Alex is comparing two irrigation systems for his garden. System A uses drip irrigation, and System B uses sprinklers. How does System A align better with responsible water consumption?
	a) System A is more visually appealing than System B.		b) System A requires more water for the same coverage.
	c) System A distributes water evenly, minimising wastage.		d) System A operates faster, saving time.

Q.3	Lucas decided to explore the forest and uncover its mysteries. Amidst his exploration, Lucas met an elder from his village who shared wisdom about the forest's significance. What role does the forest play in soil erosion?
	a) The forest has no impact on soil erosion or land stability.		b) It contributes to soil erosion by retaining excess water.
	c) It acts as a shield against soil erosion and maintains land stability.		d) It promotes landslides due to dense vegetation.

Q.4	The team found that the absence of natural vegetation had disrupted the local hydrological cycle, leading to water scarcity in the region. What would be the most effective strategy to restore the hydrological balance in this area?
	a) Introducing more non-native plant species.		b) Constructing more dams to manage water flow.
	c) Restoring native vegetation to improve water retention.		d) Encouraging excessive irrigation to boost plant growth.

Q.5	During a marine biology field trip, Emma and her classmates explored a tidal ecosystem. They observed the diverse life forms thriving in the area, including decomposers breaking down organic matter. What might occur in the tidal ecosystem if the activity of decomposers significantly declined?
	a) Increased biodiversity due to reduced competition		b) Accumulation of organic matter leading to oxygen depletion
	c) Faster recycling of nutrients within the ecosystem		d) Improved water quality and clarity

Q.6	While exploring climate change's impact on ocean health, a group of students identified a process significantly contributing to ocean acidification. What aspect of climate change primarily leads to the acidification of the ocean, affecting marine organisms?
	a) Decreased levels of greenhouse gases in the atmosphere.		b) Elevated ocean temperatures foster favourable conditions for marine life.
