Total Marks: 40
Topic: Human Geography (syllabus-first, Stage 4/5 generated; not claimed as past-year derived)

Section A

1. [1] Informal housing / squatter settlement.
Teaching note: Informal housing is built without official approval. Squatter settlements use makeshift materials. Common mistake: writing “HDB” (that is formal).

2. [1] NEWater.
Teaching note: NEWater is recycled treated used water, one of Singapore’s Four National Taps (local catchment, imported, NEWater, desalination).

3. [1] Space.
Teaching note: Geographical concepts: Space (location), Place (meaning), Environment (interaction), Scale (level).

4. [1] Urbanisation (or rural-urban migration).
Teaching note: Movement from villages to cities is rural-urban migration, a driver of urbanisation.

5. [1] HDB flat / bungalow / terrace house.
Teaching note: Formal housing is planned. Any one Singapore example accepted.

Section B

6. [2] Characteristic: dense cluster of self-built shacks with corrugated roofs. Problem: open drains cause poor sanitation / flooding.
Marking: 1 mark description, 1 mark problem linked.
Teaching note: Photo shows informal settlement; lack of planning creates health risks.

7. [2] Population increased steadily from 120,000 in 2000 to 250,000 in 2020; rise of 130,000 over 20 years.
Marking: 1 mark overall trend, 1 mark with statistics.
Teaching note: Use data points; “increased” alone insufficient.

8. [2] % increase = (250−120)/120 × 100 = 130/120 × 100 ≈ 108.3%.
Marking: 1 mark working, 1 mark answer.
Teaching note: Formula: (new−old)/old ×100. Show steps.

9. [1] High-rise apartments (60%).
Teaching note: Largest bar is high-rise.

10. [3] High-rise apartments use less land per person (1), allow more people in small area (1), reducing sprawl and preserving green space (1).
Teaching note: Land scarcity in SG makes vertical housing sustainable.

11. [1] 0304.
Teaching note: Easting first (03), northing second (04). Common trap: reversing.

12. [3] Charges drivers entering congested zone (1) → fewer cars (1) → less traffic and emissions (1).
Teaching note: Policy mechanism must link to outcome.

13. [2] Benefit: reduces heat (1) as plants absorb sunlight; improves air (1).
Marking: 1 mark feature, 1 mark benefit.

14. [2] Lack of affordable formal housing (1); rural poverty pushing migration (1).
Teaching note: Push-pull factors.

15. [1] Deficit = 40 − 100 = −60 mm (or 60 mm deficit).
Teaching note: Precipitation − ET; negative means deficit.

Section C

16. [4] More people → more water demand (1); higher impervious surface reduces groundwater recharge (1); pollution from sewage (1); strain on supply needing imports/tech (1).
Marking descriptors: 4 clear links.

17. [4] (a) Formal: concrete/brick; Informal: wood/scrap (2). (b) Formal: piped water, electricity; Informal: none or illegal (2).
Teaching note: Contrast shows planning difference.

18. [4] Trees cut → stored carbon released as CO2 (1); fewer trees absorb CO2 (1); atmospheric CO2 rises (1); greenhouse effect strengthened (1).
Marking: Chain steps each 1.

19. [4] Desalination: removes salt from seawater (1) → independent of rain (1) → reliable supply (1) but energy-costly (1, evaluation).
Teaching note: Evaluate = state + limitation.

20. [3] Location B (1): quiet, residents relaxed to answer (1); representative of housing satisfaction (1).
Teaching note: Fieldwork suitability: accessibility, safety, representativeness.
