Q.1	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

Q.2	In a region prone to erratic weather patterns, farmers face the recurring challenge of water scarcity. A group of agricultural researchers suggests adopting sustainable practices to mitigate the effects of drought. What would be the most effective way to implement this solution?

Q.3	The government of a country is planning to build a new nuclear power plant to meet increasing energy demands. The scientists and engineers involved are discussing the choice of uranium isotopes for fuel. During the discussion, they are considering various factors for the most suitable isotope. Considering the discussion among the scientists and engineers, why is uranium-235 (U-235) preferred for nuclear fission in power plants?

Q.4	You're the sustainability coordinator for your school, tasked with analysing and improving waste management practices. To assess current methods, you gather information on various practices used by students and staff. Analyse each scenario and identify the most appropriate 5R category it falls into: Reduce, Reuse, Recycle, Repurpose, or Refuse. Scenario 1: The school cafeteria replaces single-use plastic water bottles with reusable water bottles for students to bring from home. Scenario 2: The school declines any subscription to promotional materials. Scenario 3: The school installs motion sensor lights in hallways and classrooms to minimise unnecessary energy usage. Scenario 4: The art department uses leftover fabric scraps from previous projects to create new artwork and decorations. Scenario 5: The school has separate bins for paper, cardboard, and plastic bottles.

Q.5	Consider the case study given below and answer the following question: Title: Forests as Crucial Carbon Capture Systems Forests play a critical role in mitigating climate change by capturing and storing carbon dioxide from the atmosphere. Trees absorb carbon dioxide through photosynthesis and use it to grow. The carbon is then stored in the tree's biomass (wood, leaves, branches, and roots) and soil. Forests also help to regulate the climate by releasing water vapour into the atmosphere, which can form clouds and reflect sunlight back into space. Trees are the most significant carbon sink in forests, storing carbon in their biomass. The amount of carbon stored in a tree depends on its species, size, and age. Young forests capture carbon rapidly due to the quick growth of trees. Middle-aged forests store relatively greater amounts of carbon as trees grow slower but sequester more carbon. Old-growth forests contain large trees that retain carbon for extended periods, albeit at a slower rate due to fewer trees overall. Forest soils contain diverse forms of carbon influenced by soil type, vegetation, and geography. Soil properties, such as high organic content or frozen conditions, significantly impact carbon storage potential. The carbon captured by forests is eventually returned to the atmosphere through processes like decomposition and respiration. Different forest types exhibit varying rates of carbon capture and release. Tropical forests capture carbon rapidly but can release it quickly too. In contrast, temperate forests offer a balanced solution. Effective management strategies, such as forest preservation, sustainable forestry practices, forest expansion, and invasive species control, are crucial in optimising carbon sequestration potential while maintaining ecosystem balance. A farmer is contemplating converting a section of their farmland into a forest to optimise carbon sequestration potential. Which set of actions would best help the farmer achieve this goal? 1. Plant a mix of tree species known for fast growth and high carbon storage capacity. 2. Plant trees that are native to the region. 3. Leave the soil unplanted and unattended to encourage natural regeneration of native vegetation.

Q.6	A group of conservationists is conducting a study in a coastal region known for its diverse ecosystem. They notice a significant decline in the population of native plant species due to the introduction of non-native plants by human activities. As they delve deeper into their research, they aim to assess the significance of native species within this ecosystem. What role do native species most likely play in this coastal ecosystem?

Q.7	You are part of a community initiative aiming to reduce carbon emissions and combat climate change. The group is discussing strategies, and one member proposes focusing on energy efficiency. Which statement best supports the role of energy efficiency in this context?

Q.8	A local river, which serves as a crucial water source for the community, has been experiencing deteriorating water quality. Which parameter is primarily used to indicate organic pollution in freshwater systems?

Q.9	Given below is a flowchart illustrating how human activities contribute to climate change and its consequences. Identify the gaps marked as A, B, C, and D based on your understanding.
