Q.1	A study conducted in the North Atlantic found that a specific population of cod had been overfished for decades. As a result, the average size of cod in the population had decreased by 20%. What are the potential consequences of this decrease in size for the cod population?
	a) Increased spawning success due to smaller fish being quicker to reproduce		b) Reduced predation pressure due to smaller fish being less visible to predators
	c) Decreased survival rates due to smaller fish being weaker and less competitive		d) Increased genetic diversity due to the introduction of new genetic material

Q.2	A rural village has limited access to electricity, relying primarily on kerosene lamps for lighting. Kerosene use has been linked to respiratory problems and indoor air pollution. The village council is considering ways to improve access to clean and reliable electricity. Which of the following would be the most effective long-term solution to address both health concerns and energy needs?
	a) Distributing more kerosene lamps with improved ventilation.		b) Providing solar-powered lighting systems to each household.
	c) Encouraging households to use candles instead of kerosene lamps.		d) Constructing additional diesel-powered generators for increased electricity.

Q.3	A community relies on a rainwater harvesting system for its water supply. The system collects rainwater from rooftops and stores it in large underground tanks. After a heavy rainfall, the residents notice that the stored water has a brownish colour and an unpleasant odour. What could be the most likely cause of this contamination? 1. Insufficient filtration and disinfection of the rainwater 2. Accumulation of organic debris in the storage tanks 3. Leaching of pollutants from roofing materials
	a) Only 1		b) Only 1 and 2
	c) Only 2 and 3		d) 1, 2 and 3

Q.4	In a community relying on private well water, residents suspect mercury contamination due to industrial activities in the vicinity. They conduct water tests, and the results show varying mercury concentrations across different households. Analyse the provided table showcasing mercury levels in parts per billion (ppb) from five different wells. Based on the data, which conclusion is most likely accurate regarding the mercury contamination in the private wells? Well Number Mercury Concentration (ppb) Well 1 0.8 Well 2 4.3 Well 3 1.5 Well 4 0.3 Well 5 3.9
	a) The contamination is evenly distributed across all wells due to a single, widespread source.		b) The shallowest well (with the lowest water table) is likely the most contaminated.
	c) Only some wells show elevated mercury levels, suggesting localised sources of contamination.		d) The contamination originates from an industrial facility located closest to Well 2.

Q.5	An environmental organisation has embarked on a project aimed at restoring a degraded river ecosystem. The project involves reintroducing native fish species that have declined due to habitat degradation and water quality issues. Additionally, efforts are being made to improve overall water quality by implementing measures to reduce pollution and restore natural habitat. What could be an anticipated outcome of this restoration effort in the degraded river ecosystem?
	a) Increased biodiversity with the recovery of native fish populations and the return of other aquatic species.		b) Further degradation due to competition among reintroduced fish species and disruption of the existing ecosystem balance.
	c) Decline in water quality as a result of releasing additional fish into an already stressed environment.		d) No significant impact on the river ecosystem as previous damage is irreversible.
