O-Level Geography Quiz - Resources Sustainability (Answer Key)

Total Marks: 40 | Duration: 60 min

Section A Answers (Q1–8)

Q1 [1 mark]
Answer: Sustainable development is "development that meets the needs of the present without compromising the ability of future generations to meet their own needs" (Brundtland Report, 1987).
Teaching note: This is the standard definition; accept any close paraphrase. Key idea: intergenerational equity.

Q2 [1 mark]
Answer: Ecocentric.
Teaching note: Ecocentric = nature valued for itself; anthropocentric = nature valued for human benefit. The statement says "regardless of human use" → ecocentric.

Q3 [1 mark]
Answer: Resource-dependent / import-dependent country. (Accept "resource-scarce")
Teaching note: Singapore is resource-scarce; term shows reliance on external supply.

Q4 [2 marks]
Working: Mean = (120+115+130+125+140+135) / 6 = 765 / 6 = 127.5 million litres.
Answer: 127.5 million litres.
Mark breakdown: 1 for sum, 1 for division & unit. Common mistake: omitting unit or wrong division.

Q5 [1 mark]
Answer: Country A (5%).
Teaching note: From placeholder chart, A bar is shortest at 5%.

Q6 [1 mark]
Answer: Coal / oil / natural gas (any one).
Teaching note: Non-renewable = formed over millions of years, finite.

Q7 [2 marks]
Answer: Reducing food waste means less land, water and energy used for production that is thrown away; lowers methane from landfills. (1 mark reason, 1 mark link to sustainability)
Teaching note: Connects resource efficiency and emissions.

Q8 [3 marks]
Answer: Use a bar chart with x-axis = 4 locations, y-axis = average electricity use (kWh), bars for each location; or line graph if over time. Must be ONE graph with legend/labels.
Marking: 1 graph type, 1 axes labelled, 1 all 4 locations on same graph. Trap: separate graphs not accepted.

Section B Answers (Q9–14)

Q9 [4 marks]
(a) NEWater (recycled wastewater) – 2 marks for description.
(b) Catchment management / import diversification / desalination – 2 marks.
