Q.1	Consider a scenario where a city implements extensive water conservation methods, reducing wastewater released into rivers by 40%. If initially, 1,000 cubic meters of wastewater flowed into rivers per day, what would be the new daily volume released after conservation efforts?
	a) 1,400 cubic meters		b) 350 cubic meters
	c) 600 cubic meters		d) 400 cubic meters

Q.2	Considering the impact of climate change, which of the following species is likely to face the highest risk of endangerment? 1. A migratory bird species 2. A deep-sea fish species 3. A reptile species in a tropical forest
	a) Only 1		b) Only 1 and 2
	c) Only 2 and 3		d) 1, 2 and 3

Q.3	The school cafeteria has decided to install energy-efficient appliances. They replaced the older refrigerator and cooking equipment with energy-star rated models. How might this change affect the school's energy consumption over a year?
	a) Increase significantly		b) Decrease gradually
	c) No change		d) Fluctuate unpredictably

Q.4	Imagine a bustling city facing the challenge of managing heavy rainfall. They implement a green infrastructure system, incorporating elements like bioswales and rain gardens. But what role do these play in keeping the city healthy and functioning smoothly?
	a) Diverting stormwater to increase flooding risks		b) Enhancing pollution in water bodies
	c) Filtering and absorbing stormwater to prevent runoff pollution		d) Reducing access to green spaces for the community

Q.5	A restaurant implements some new practices in their kitchen, such as using a dishwasher efficiently and fixing leaks promptly. What impact does this have on their overall sustainability?
	a) It has no effect on sustainability.		b) It reduces water consumption and contributes positively to sustainability.
	c) It increases water wastage and negatively affects sustainability.		d) It solely improves the restaurant's kitchen hygiene but doesn't impact sustainability.

Q.6	At the Eco-Olympiad, a challenge tests students' knowledge of protein sources and their environmental impact. Which protein source would likely have the highest environmental impact?
	a) Tofu		b) Chicken
	c) Lentils		d) Almonds

Q.7	Your once-sunny city seems shrouded in a hazy cloud of smog, especially during winter. Cars and factories are the main culprits, but everyone suffers from breathing difficulties and reduced visibility. Which air pollutants from fossil fuels are likely contributing to this smog, and how can your city combat these issues?
	a) Fine particulate matter from car dust and industrial activities traps pollutants in the air, worsening smog. Investing in public transportation and green spaces can alleviate the problem.		b) Carbon dioxide, the main greenhouse gas from fossil fuels, directly contributes to smog, and the solution lies solely in switching to renewable energy sources like solar and wind.
	c) Nitrogen dioxide and sulphur dioxide from vehicle exhausts and factory emissions combine with sunlight to form harmful smog, which can be tackled by promoting electric vehicles and stricter emission regulations.		d) Smog is primarily caused by natural phenomena like dust storms and forest fires, and the city should focus on preparing for these events rather than blaming fossil fuels.

During their research, the scientists observed a correlation between land-based environments and the overall health of marine ecosystems. Choose an appropriate option that best reflects the importance of terrestrial ecosystems for marine life.
	a) Land-based environments have minimal impact on marine ecosystems, thus their significance is negligible.		b) Terrestrial environments act as a buffer, filtering pollutants before they reach the oceans, thus preserving marine habitats.
	c) Marine ecosystems are entirely independent of land-based environments, having no ecological connections.		d) Human activities in terrestrial ecosystems do not affect the quality of water in marine environments.

Q.10	Sarah is discussing climate change in her geography class. She mentions that climate and weather are often confused but differ significantly. Which statement best defines climate compared to weather?
