Marking Scheme & Answers

Note to Markers:

• Accept reasonable alternatives that are syllabus-aligned.
• For inference/purpose questions, answers must be derived from the source content/context.
• For evaluation questions, look for the "Point + Explanation + Evidence" structure.

Case Study: Managing Water Security

1. What is the message of Source A about the role of technology in solving Singapore’s water issues? [1]

• Answer: Source A suggests that technology (NEWater/Desalination) plays the dominant/most significant role in solving water issues, making individual conservation efforts seem small or insignificant in comparison.
• Marking: 1 mark for identifying the dominance of technology vs. the insignificance of individual effort.

2. Study Source B. Why does the Minister emphasize the need for citizens to practice responsible consumption? [2]

• Answer:
  1. Producing desalinated water is energy-intensive and costly, so wasting water increases costs and carbon footprint. [1]
  2. Shared responsibility ensures water remains affordable and sustainable for future generations. [1]
• Marking: 1 mark per distinct reason derived from the text.

3. Study Source C. How far does the author agree with the government’s current approach to water security? [2]

• Answer: The author largely disagrees. [1] They believe the focus on high-tech solutions (desalination) is "misguided" and harmful to the environment, arguing instead for demand reduction and nature-based solutions. [1]
• Marking: 1 mark for stance (disagree), 1 mark for explanation from text.

4. Compare Sources B and C. How far do they agree about the best way to ensure water sustainability? [4]

• Answer:
  • Agreement: Both sources agree that current practices need to change to ensure sustainability. Both imply that resource management is critical. (1 mark for identifying a similarity, though explicit agreement is low). Note: Actually, they disagree on the primary method.
  • Disagreement: Source B supports the government’s multi-pronged approach, including technology (NEWater/Desalination) AND citizen conservation. Source C rejects the technological focus, arguing it causes environmental harm (carbon footprint), and advocates for strict regulations on industry and nature-based solutions instead.
  • Extent: They disagree significantly on the method. Source B sees technology as essential; Source C sees it as problematic. They only agree on the goal (sustainability) but not the means.
• Marking:
  • 1 mark for identifying a point of comparison (e.g., both discuss sustainability).
  • 1 mark for explaining Source B’s view.
  • 1 mark for explaining Source C’s view.
  • 1 mark for a clear judgment on the extent of agreement (e.g., "They largely disagree on the role of technology").

5. Study Source D. How useful is Source D to a student studying the challenges of Singapore’s water security? [5]

• Answer:
  • Useful: It provides quantitative data on the current mix of water sources, showing heavy reliance on NEWater (40%) and Imports (30%). This highlights the challenge of dependency on imports and the success of technology. [2]
  • Useful: It shows the cost and energy intensity, highlighting the economic and environmental challenges of desalination (High cost/Very High energy). [1]
  • Limitations: It is a snapshot from 2023, so it doesn’t show future trends or the impact of climate change on local catchment. [1]
  • Limitations: It does not explain the political challenges of imported water (e.g., relations with Malaysia), which is a key security challenge. [1]
• Marking:
  • Up to 3 marks for usefulness (Point + Explanation + Evidence from table).
  • Up to 2 marks for limitations (Point + Explanation).

6. "Technological solutions are more important than citizen action in ensuring Singapore’s water security." Using the sources and your own knowledge, do you agree? [16] (Note: This is a structured outline for marking. In a real exam, students write paragraphs.)

• Arguments for Agreement (Technology is more important):

  • Point 1: Singapore has limited land for catchment. Technology (NEWater/Desalination) creates new water sources independent of rainfall.
  • Evidence: Source D shows NEWater and Desalination make up 60% of supply. Source B mentions billions invested in these plants.
  • Point 2: Technology ensures self-reliance and reduces vulnerability to external shocks (e.g., import cuts).
  • Evidence: Source B states imports are risky due to geopolitical tensions. Technology provides a buffer.

• Arguments against Agreement (Citizen action is equally/more important):

  • Point 1: Technology is expensive and energy-intensive. Without conservation, costs and environmental impact become unsustainable.
  • Evidence: Source B mentions high energy/cost of desalination. Source C argues tech contributes to climate change.
  • Point 2: Demand management is crucial. If demand exceeds supply, technology cannot keep up indefinitely.
  • Evidence: Source A implies individual effort is small, but Source B argues "every drop counts." Own knowledge: Water pricing and public education campaigns are key to keeping demand manageable.

• Conclusion:

  • Both are essential. Technology provides the supply, but citizen action manages the demand. Relying only on technology is costly and environmentally damaging; relying only on conservation is insufficient for a growing economy. A balanced approach (shared responsibility) is best.

Additional Source-Based Skill Drills (Questions 7-20)

7. What can you infer about the author’s attitude towards civic participation? [1]

• Answer: The author feels empowered/positive about civic participation, believing it gives them a voice.
• Marking: 1 mark for positive/empowered attitude.

8. What is the purpose of this poster? [1]

• Answer: To promote racial harmony and encourage social interaction among different races through shared activities (eating).
• Marking: 1 mark for promoting harmony/interaction.

9. Why might this source be unreliable for understanding the work ethic of the local population at that time? [2]

• Answer:
  1. The author is a merchant with a biased perspective (likely wanting cheaper/faster labor). [1]
  2. It is a subjective opinion ("complaining") rather than objective data on productivity. [1]

10. What is one economic impact of globalisation mentioned in the source? [1]

• Answer: Relocation of factories/jobs to countries with lower labour costs (or job loss in home country).
• Marking: 1 mark for job relocation/cost advantage.

11. How do Source X and Source Y differ in their explanation for the drop in crime? [2]

• Answer: Source X attributes it to enforcement/strict laws (top-down). Source Y attributes it to community engagement/trust (bottom-up).
• Marking: 1 mark for each distinct cause.
