Q.1	Which innovative water purification method uses a combination of biological processes involving microorganisms to break down organic matter and remove contaminants from wastewater?
	a) Coagulation		b) Sedimentation
	c) Membrane bioreactors		d) Flocculation

Q.2	You're at the supermarket deciding between locally-grown organic vegetables and conventionally-grown vegetables shipped from a distant country. Both cost the same. Considering climate change:
	a) The local organic option is always better due to reduced transportation emissions.		b) Choose conventionally grown vegetables, as organic farming uses more water.
	c) Consider additional factors like packaging and water usage alongside transportation emissions.		d) Both options have similar climate impacts, so focus on personal preference.

Q.3	A farmer uses a private well to irrigate his crops. He notices that the well water has become increasingly salty over the past few years, affecting the growth and yield of his crops. What could be the most likely reason for this increase in salinity?
	a) Overextraction of groundwater from nearby wells		b) Intrusion of seawater into the freshwater aquifer
	c) Application of fertilisers and pesticides on the farmland		d) Changes in rainfall patterns and natural recharge rates

Q.4	You are troubleshooting a high electricity bill and notice that even when all appliances are turned off, the energy meter is still registering a small amount of power usage. This phenomenon is known as a vampire load. What is the main reason why vampire loads occur in most appliances?
	a) Appliances continue to draw a small amount of power even when they are turned off.		b) Appliances are not properly grounded, which causes them to leak electricity.
	c) Appliances are designed to be constantly turned on, so they use more energy when they are off.		d) Appliances are not properly connected to power outlets, which causes them to malfunction.

Q.5	Consider the case study given below and answer the following question: Case Study: Protecting the Coral Reefs of Raja Ampat, Indonesia Location: Raja Ampat, a stunning archipelago in Indonesia famed for its thriving coral reefs, biodiversity, and diving tourism. Challenges: -Overfishing: Unsustainable fishing practices, including blast fishing and cyanide fishing, have depleted fish stocks and damaged coral reefs. -Pollution: Plastic pollution, agricultural runoff, and sedimentation from coastal development all threaten the delicate marine ecosystem. -Climate Change: Rising ocean temperatures and acidification are bleaching and killing coral, the foundation of the reef ecosystem. Initiatives: -Marine Protected Areas (MPAs): Establishing and enforcing MPAs restricts harmful fishing practices and allows reefs to recover. Raja Ampat boasts one of the largest MPAs in Southeast Asia, covering over 1.5 million hectares. -Community-Based Management: Local communities play a crucial role in protecting their reefs. The Coral Triangle Initiative focuses on empowering them through sustainable fishing practices and alternative livelihoods like ecotourism. -Sustainable Aquaculture: Farming fish responsibly reduces pressure on wild stocks and provides alternative income for fishermen. Locally managed fish farms in Raja Ampat demonstrate successful alternatives to overfishing. -Coral Restoration: Innovative techniques like coral nurseries and transplantation help regenerate damaged reefs and restore marine biodiversity. Outcomes: -Fish stocks are rebounding: The Raja Ampat MPA has shown a significant increase in fish biomass within its boundaries, demonstrating the effectiveness of protected areas. -Improved water quality: Reduced pollution and sedimentation contribute to healthier corals and a more vibrant marine environment. -Empowered communities: Local involvement in conservation fosters environmental stewardship and provides sustainable economic opportunities. Raja Ampat serves as a beacon of hope in marine conservation, demonstrating the effectiveness of community-driven, multi-pronged approaches to protecting life below water. By tackling overfishing, pollution, and climate change, we can safeguard the future of these vital ecosystems and the communities that depend on them. In the case study, it is mentioned that coral reefs confront challenges from pollution and climate change. How do these challenges interact to negatively affect Raja Ampat's coral reefs? 1. Pollution weakens coral reefs, making them more susceptible to bleaching and mortality as ocean temperatures rise. 2. Climate change alters ocean currents, causing an increased accumulation of pollutants near reefs, adding to their stress. 3. Pollution can harm reefs, but it doesn't significantly affect their vulnerability to climate change impacts.
