Q.1	In a remote village, a community initiative introduced a water purification system, significantly improving water quality. Consider the multifaceted impact of the improved water quality on the village. What aspects of community life might have been positively influenced by this initiative?
	a) Increased agricultural yield due to better irrigation		b) Reduction in waterborne diseases, promoting better health
	c) Decline in local wildlife population due to altered water composition		d) Higher electricity consumption due to improved water availability

Q.2	While snorkelling, Mia notices vibrant coral reefs teeming with tiny fish and colourful invertebrates. What role do these small creatures play in the marine food web?
	a) Primary producers: They capture sunlight and produce food for herbivores.		b) Secondary consumers: They hunt smaller fish and invertebrates for sustenance.
	c) Primary consumers: They graze on algae and provide food for larger predators.		d) Apex predators: They occupy the top of the food chain with few natural predators.

Q.3	Why is rainwater harvesting beneficial for water management in regions prone to water scarcity? 1. It provides an alternative source of water during dry periods. 2. It increases dependency on municipal water supplies. 3. It leads to excessive water wastage. 4. It has a negative impact on the environment.
	a) Only 1		b) Only 2
	c) Both 2 and 3		d) Both 2 and 4

Q.4	Emily is a college student who is passionate about promoting sustainable transportation. She believes in reducing carbon emissions and minimising her environmental impact. Emily commutes to her campus using eco-friendly transportation options. How does Emily commute to her college campus?
	a) Biking and using public transportation		b) Driving alone in a gas-guzzling car
	c) Renting a limousine everyday		d) Using a motorbike without a helmet

Q.5	Arya is a marine scientist who is studying the impact of climate change on the marine food web. She notices that the populations of some fish species are declining, while the populations of other fish species are increasing. She also notices that the populations of some phytoplankton species are declining, while the populations of other phytoplankton species are increasing. What could be the reason for these changes in the marine food web? 1. Climate change is causing the ocean to become warmer, which is affecting the distribution of fish species. 2. Climate change is causing the ocean to become more acidic, which is affecting the distribution of phytoplankton species. 3. Climate change is causing the ocean to become more polluted, which is affecting the distribution of both fish and phytoplankton species.
