Q.1	The local government encourages citizens to repair broken household items rather than replace them. Which statements correctly explain how this supports responsible consumption and production? It extends product lifespans and delays disposal. It reduces demand for materials used to manufacture replacements. It eliminates the need for resources when maintaining products.
	a) Only 1		b) Only 1 and 2
	c) Only 2 and 3		d) 1, 2 and 3

Q.2	At Greenway Middle School, the cafeteria decided to track food waste over a week. The given table represents the daily amount of food wasted. If the school wants to reduce food waste by 20%, how much food, in kilograms, should they aim to save each day? Day Food Waste (kg) Monday 2.8 Tuesday 3.5 Wednesday 4.2 Thursday 5.1 Friday 3.9 Saturday 3.2 Sunday 2.6
	a) 3.2 kg		b) 0.72 kg
	c) 5.06 kg		d) 25.3 kg

Q.3	A study in a river basin area shown in the picture reveals that the concentration of heavy metals in the water significantly exceeds permissible limits downstream of an industrial area. What can be inferred from this data?
	a) Heavy metals have no impact on water quality		b) The river basin acts as a natural filter, reducing pollution
	c) Industrial activities are likely the source of heavy metal pollution		d) The upstream area is more polluted due to urban development

Q.4	Sophie and her marine biology class observe an oil spill caused by a tanker accident. How can this spill disrupt marine food webs?
	a) By supplying nutrients that increase food availability throughout the ecosystem.		b) By removing predators while leaving their prey unaffected by contamination.
	c) By forming a surface layer that improves photosynthesis in marine algae.		d) By harming organisms and reducing food available to their consumers.

Q.5	A company compares packaging for the same household cleaner. All options provide equal cleaning performance. Which approach most directly reduces repeated packaging use and the transport of water?
