Q.1	Mark and Sarah are discussing ways to conserve water at home. Mark argues that taking shorter showers helps save water, while Sarah believes that using a dishwasher consumes less water than hand washing dishes. In the context of water conservation at home, which statement aligns more with effective water-saving practices based on Mark and Sarah's discussion?
	a) Mark's shorter showers significantly conserve more water than Sarah's dishwasher usage.		b) Sarah's claim of a dishwasher using less water compared to hand washing dishes is more water-efficient.
	c) Both Mark and Sarah's approaches contribute equally to water conservation efforts.		d) Neither Mark's shorter showers nor Sarah's dishwasher usage significantly impact water conservation.

Q.2	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.3	A rapidly growing city is planning its expansion. Developer A proposes building high-rise apartments with minimal green space to maximise housing, while Developer B advocates for incorporating several large parks and green corridors throughout the development. A heated debate ensues, with arguments for and against each approach. Which developer makes the stronger case for the city's long-term well-being, and why?
	a) Developer A, as maximising housing density reduces transportation demands and promotes social interaction.		b) Developer B, as urban green spaces contribute to cleaner air, lower temperatures, and improved mental health of residents.
	c) Both developers offer equally valid points, and the decision should be based on economic considerations.		d) Neither developer, as further studies are needed on the impact of green spaces in megacities.

Q.4	The students are examining nuclear energy and its environmental implications. Considering their long-term impact and safety hazards, what constitutes the primary environmental concern linked to nuclear power plants?
	a) Dissemination of greenhouse gases leading to climate alteration.		b) Discharge of particulate matter resulting in regional air pollution.
	c) Accumulation of radioactive waste and the potential for accidents.		d) Contribution to soil degradation and ecosystem destabilisation.

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	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?

	c) System A distributes water evenly, minimising wastage.		d) System A operates faster, saving time.

Q.7	Noah is exploring the impact of nutrient pollution on marine ecosystems. How does nutrient pollution, such as excess nitrogen and phosphorus, primarily affect marine habitats?
	a) Enhancing biodiversity by promoting the growth of various marine species.		b) Decreasing oxygen levels and causing harmful algal blooms.
	c) Balancing pH levels in affected marine environments.		d) Strengthening the resilience of marine food webs.

Q.8	Max loves animals and often visits a nearby park to watch them. He noticed that the park was being divided by roads and buildings, making it harder for animals to move around freely. What is this breaking up of habitats called?
