Q.1	In a city prone to heatwaves, a group of students proposed a rooftop garden initiative to combat the urban heat island effect. How does the presence of rooftop gardens contribute to reducing the urban heat island effect?
	a) Rooftop gardens reduce surface temperatures by providing shade and evaporative cooling		b) Rooftop gardens release excess heat into the atmosphere
	c) Rooftop gardens increase heat absorption from the sun		d) Rooftop gardens accelerate the formation of smog

Q.2	A major Himalayan glacier, a vital source of freshwater for millions downstream, is retreating at an alarming rate. Satellite imagery reveals a significant decrease in the glacier's mass over the past few years. Data also shows a connection between rising global temperatures and the accelerated melting of glaciers worldwide. Considering the scenario, which of the following is the most likely consequence of the glacier's retreat for the communities downstream?
	a) Increased hydropower generation due to higher water flow		b) Improved water quality
	c) Enhanced biodiversity in the surrounding ecosystem due to the release of nutrients		d) Water scarcity and competition for resources among communities

Q.3	A group of students, with a keen interest in studying a wide array of plant and animal species in their natural habitat, is planning an educational expedition. They aim to explore a biome that offers the highest biodiversity for their research. Which biome among the following options would provide the most diverse range of plant and animal species for the students to observe?
	a) Tundra		b) Tropical rainforest
	c) Boreal forest		d) Temperate forest

Q.4	A family living in a region with abundant clean hydropower is considering replacing their ageing gas oven with a new electric model.
