Q.1	Two islands in the Pacific Ocean experience similar climates but have different levels of deforestation. Island A has lost 80% of its original forest cover, while Island B has maintained 90% of its forest. Over the past decade, Island A has experienced more frequent and intense heat waves compared to Island B. Which of the following is the most likely explanation for this difference?
	a) Island B benefits from cooler ocean currents that moderate its climate, while Island A does not.		b) Island A's proximity to volcanic activity contributes to increased heatwaves.
	c) Island A has a higher concentration of greenhouse gases in its atmosphere due to reduced carbon sequestration by forests.		d) Island B's higher elevation reduces the likelihood of extreme heatwaves.

Q.2	In a scenario where a factory discharges untreated industrial wastewater containing high levels of heavy metals into a nearby river, what long-term impact would this have on the aquatic ecosystem?
	a) Decreased biodiversity due to increased nutrient levels		b) Bioaccumulation of heavy metals leading to toxicity in aquatic organisms
	c) Growth of indigenous species due to enrichment of the ecosystem		d) Eutrophication due to sedimentation of metals

Q.3	You are an environmental consultant hired by a local community to assess the potential environmental impacts of a proposed aquaculture farm. The farm plans to raise salmon in open-net cages in a bay adjacent to a sensitive coral reef ecosystem. Based on your knowledge of aquaculture and the local environment, which of the following potential environmental concerns should you prioritise in your assessment? 1. The farm's operations could increase the risk of eutrophication 2. The farm's waste products could pollute the water and harm the coral reef 3. The farm will alleviate pressure on overfished wild populations
