International Green Warrior Olympiad Class 10 Previous Year Paper

Q.1

You're passionate about reducing your environmental footprint, particularly concerning packaging materials. You've come across a study that highlights the significance of recycling and reuse in lessening the environmental impact of packaging.
Which of the following statements accurately reflects the environmental impact of recycling and reuse in relation to packaging materials?

Q.2

You are watching a wildlife documentary where a pod of migrating humpback whales suddenly changed their course, avoiding a polluted area in the river. It was later shown that the scientists discovered high levels of mercury in the water.
How could this pollution potentially threaten the whales?
1. Weaken their immune system
2. Damage their nervous system, impacting movement
3. Blur their vision, hindering navigation and hunting

Q.3

Geneva is an aquatic biologist working for a local environmental agency. She is studying the impact of excess nutrients and increasing atmospheric CO₂ on the health of a nearby bay. She is concerned that the combined effects of these factors could be harming marine life and disrupting the ecosystem.
She has developed a flow chart representing the relationships between various elements.
Based on your understanding of aquatic ecosystems, identify A, B, C, D, and E.

Q.4

A team of environmentalists is proposing the establishment of a protected area that integrates conservation efforts with sustainable development. This proposed area aims to safeguard biodiversity while allowing human activities that are compatible with nature conservation.
Which type of protected area aligns best with the team's objectives?

Q.5

Biodiversity loss due to deforestation can have a cascading effect on the ecosystem. Which of the following is the LEAST likely consequence of widespread species extinction?

Q.6

In a discussion regarding the significance of tropical rainforests in global climate regulation, a group of environmental researchers is examining the mechanisms by which these forests contribute to this role.
Which mechanism or mechanisms among the following options significantly contribute to the crucial role of tropical rainforests in regulating the global climate?
1. Carbon sequestration through photosynthesis
2. Release of moisture into the atmosphere
3. Absorption of solar radiation

Q.7

An environmental organisation has embarked on a project aimed at restoring a degraded river ecosystem. The project involves reintroducing native fish species that have declined due to habitat degradation and water quality issues. Additionally, efforts are being made to improve overall water quality by implementing measures to reduce pollution and restore natural habitat.
What could be an anticipated outcome of this restoration effort in the degraded river ecosystem?

Q.8

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.9

Consider the case study given below and answer the following question:
Case Study: The Müller Family's Journey to Renewable Energy
The Müller family, residing in a charming village in the German countryside, had always been conscious about their environmental impact. In 2022, they decided to take an active step towards a greener lifestyle by installing a rooftop solar panel system. Their primary motivation was to reduce their reliance on fossil fuels and contribute to mitigating climate change. However, as they embarked on this journey, they discovered a plethora of other benefits:
Environmental Benefits:
-Reduced Carbon Footprint: The solar panels generated clean energy, leading to a significant reduction in their carbon emissions. This translated to a cleaner environment for their family, their community, and the planet.
-Improved Air Quality: By relying less on fossil fuels, the Müllers contributed to cleaner air in their region, which improved their overall health and well-being.
Financial Benefits:
-Reduced Electricity Bills: The solar panels generate enough electricity to cover a significant portion of their household energy needs, resulting in substantial savings on their monthly electricity bills. This provided them with financial stability and freed up resources for other expenses.
-Government Incentives: The German government offers various financial incentives for individuals and families adopting renewable energy solutions. The Müllers took advantage of these incentives, further reducing the cost of their solar panel system and accelerating their return on investment.
Lifestyle Benefits:
-Energy Independence: The Müllers achieved a sense of energy independence by generating their own clean energy. This gave them greater control over their energy consumption and reduced their dependence on the national grid, especially during peak hours.
-Enhanced Home Value: Homes with renewable energy systems are becoming increasingly sought-after, leading to a potential increase in the value of the Müller's property.
Overall Impact:
The Müller family's experience showcases the numerous benefits of adopting renewable energy in a domestic setting. Their commitment to environmental sustainability not only helped them create a cleaner future but also resulted in financial savings and enhanced their quality of life. Their story serves as an inspiration for others to consider switching to renewable energy and contribute to a more sustainable future.
Which of the following statements best describes the primary motivation of the Müller family to switch to renewable energy?
1. Environmental sustainability
2. Financial savings
3. Increased energy independence
4. Minimising the environmental impact

Q.10

A rural village has limited access to electricity, relying primarily on kerosene lamps for lighting. Kerosene use has been linked to respiratory problems and indoor air pollution. The village council is considering ways to improve access to clean and reliable electricity. Which of the following would be the most effective long-term solution to address both health concerns and energy needs?
