Q.1	A community in a rural area is facing water quality issues due to the presence of microbial contaminants in their water supply. Which of the following water treatment methods would be the most effective in removing microbial contaminants and ensuring safe drinking water for the entire community?
	a) Filtration		b) Boiling
	c) Chlorination		d) Distillation

Q.2	Researchers observed a significant reduction in phytoplankton populations in a study area. What potential impact does this reduction have on the carbon cycle? 1. Decrease in atmospheric CO2 levels due to reduced photosynthesis. 2. Increase in CO2 levels as phytoplankton absorb less carbon. 3. No effect on the carbon cycle as phytoplankton are not significant carbon absorbers. 4. Elevated carbon sequestration in oceans as phytoplankton decrease.
	a) Only 1		b) Only 3
	c) Both 1 and 4		d) Both 3 and 4

Q.3	Which change in agricultural practices leads to more carbon dioxide being released into the atmosphere?
	a) Using crop rotation to improve soil health		b) Planting cover crops to prevent soil erosion
	c) Clearing land for larger farms		d) Irrigating fields with recycled water

Q.4	Hannah is researching the environmental impact of food choices. She notices that a diet high in animal products contributes significantly to greenhouse gas emissions. What dietary change could Hannah suggest to her community to reduce this impact?
	a) Promoting a solely plant-based diet to eliminate greenhouse gas emissions.		b) Encouraging the consumption of more red meat and dairy products.
	c) Suggesting an increase in processed food consumption to reduce animal product intake.		d) Advocating for a balanced diet with moderate consumption of animal products.

Q.5	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.9	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.
