Q.1	A city is planning a food waste strategy that uses two groups of approaches. Group A Smart fridges alert households to food that is close to spoiling. Community kitchens turn safe, edible surplus food into meals for people in need. Group B Community composting turns food scraps that cannot be eaten into soil improver. Specialised facilities convert suitable organic waste into fertiliser and biogas. The city wants to reduce the amount of food waste sent to landfill. Which statement best explains how the two groups can work together?
	a) Group A keeps edible food in use, and Group B recovers value from the waste that remains		b) Group B recovers resources from scraps, so Group A is not needed for edible food
	c) Group A treats waste after disposal, while Group B stops food from being wasted		d) Both groups reduce landfill waste, but only by processing food after it is thrown away

Q.2	At a science camp, Mia learns about solar energy. She analyses data and finds that a solar panel generates an average of 1.5 kilowatt-hours (kWh) of electricity per day. If a household uses 6 kWh of electricity daily, how many solar panels would they need to cover their entire daily energy consumption?
	a) 2 solar panels		b) 3 solar panels
	c) 4 solar panels		d) 5 solar panels

Q.3	The table compares average annual rainfall, distance from the ocean, and vegetation cover in two regions. Location Average annual rainfall (inches) Distance from ocean Vegetation Coastal city More than 80 Near Dense Desert region Less than 5 Far Sparse Which explanation is best supported by the information in the table?
	a) Sparse vegetation is the main cause of low rainfall in the desert region		b) Dense vegetation brings in the clouds that deliver rain to the coastal city
	c) Moist air from the nearby ocean is a likely source of the coastal city’s rainfall		d) Low rainfall in the desert region shows that no evaporation occurs there

Q.4	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?
	a) Selling concentrated refills for a durable, reusable bottle.		b) Selling ready-to-use cleaner in disposable recycled plastic bottles.
	c) Selling ready-to-use cleaner in heavier, single-use glass bottles.		d) Selling diluted cleaner in individually packaged disposable sachets.

Q.5	Nick installs rooftop solar panels. What happens when photovoltaic cells absorb photons with sufficient energy?
	a) They convert sunlight into heat that circulates through household radiators.		b) They energise electrons, enabling an electric current to flow.
	c) They split water into hydrogen that supplies household fuel cells.		d) They heat stored water that drives a small electricity-generating turbine.

Q.6	Which type of pollutant in water most directly causes algal blooms?
	a) Heavy metals such as lead		b) Nitrates and phosphates
	c) Oil from ship spills		d) Disease-causing bacteria

Q.7	Students studying an inland ecosystem record rising temperatures, declining rainfall and prolonged dry periods. A moisture-dependent plant species has become less abundant. Which factor best explains its decline?
	a) Reduced soil moisture limits water uptake.		b) Warmer soil supplies more nutrients for root growth.
	c) Longer dry periods increase the water stored in soil.		d) Increased atmospheric carbon dioxide reduces water absorption.

Q.8	In a future scenario where climate change drastically alters global weather patterns, which land biome would likely experience the MOST drastic and irreversible changes?
	a) A temperate deciduous forest with distinct seasonal variations.		b) A vast and diverse tropical rainforest with abundant rainfall.
	c) A fragile arctic tundra bordering on polar ice sheets.		d) A sprawling grassland with resilient and adaptable plant communities.
