Q.1	An individual aims to make more environmentally conscious choices in their daily consumption. What habit should they adopt to support this goal?
	a) Regularly discarding and replacing electronic devices		b) Prioritising products with excessive packaging for better protection
	c) Opting for products made from recycled or sustainable materials		d) Buying single-use plastic items in large quantities for convenience

Q.2	A group of students conducted an experiment to understand the greenhouse effect and its implications. What conclusion did they likely draw about the greenhouse effect?
	a) The greenhouse effect has no impact on Earth's temperature regulation.		b) Greenhouse gases trap heat, contributing to warming the Earth's surface.
	c) Greenhouse gases prevent sunlight from reaching Earth, causing cooling.		d) The greenhouse effect only affects certain regions but not the entire planet.

Q.3	In an experiment, researchers compare the environmental impact of two vegetable farming methods. Which data would be most relevant to assess their sustainability?
	a) The total weight of vegetables produced by both methods.		b) The amount of synthetic pesticides used in each method.
	c) The biodiversity of insects and animals observed in the fields.		d) The carbon footprint and water usage associated with each farming method.

Q.4	Alex is comparing two irrigation systems for his garden. System A uses drip irrigation, and System B uses sprinklers. How does System A align better with responsible water consumption?
	a) System A is more visually appealing than System B.		b) System A requires more water for the same coverage.
	c) System A distributes water evenly, minimising wastage.		d) System A operates faster, saving time.

Q.5	Sarah is concerned about the chemicals used in water treatment. What are some of the potential drawbacks of using chlorine for disinfection? 1. Chlorine can react with organic matter in the water to form disinfection byproducts, some of which are considered harmful to human health. 2. Chlorine can contribute to taste and odour problems in the water. 3. Chlorine can be harmful to aquatic life if discharged into the environment without proper treatment.
	a) Only 1		b) Only 2
	c) Both 1 and 2		d) 1, 2 and 3
