Total Marks: 50

Section A: Map Skills [20 marks]

Question 1

(a) 2963
Method: Read eastings first (29), then northings (63). The school is in the grid square bounded by eastings 29–30 and northings 63–64. The 4-figure grid reference uses the lower-left corner: 2963.
[1]

(b) 312618
Method: For 6-figure reference, divide the grid square into tenths. The MRT station is in grid square 3161. It lies 2/10 east of easting 31 → 312. It lies 8/10 north of northing 61 → 618. Combined: 312618.
[1]

(c) 2.2 km (accept 2.1–2.3 km)
Working:

Distance on map: Measure between 2962 and 3161 → approximately 2.2 cm (using ruler on 1:25,000 map).
Ground distance = 2.2 cm × 25,000 = 55,000 cm = 550 m = 0.55 km? Wait — recheck: 1 cm on map = 25,000 cm = 0.25 km. So 2.2 cm × 0.25 km/cm = 0.55 km.
Correction: The straight-line distance between grid squares 2962 and 3161 is 2 km east (2 grid squares × 1 km) and 1 km south (1 grid square × 1 km). Using Pythagoras: √(2² + 1²) = √5 ≈ 2.24 km.
Answer: 2.2 km (accept 2.1–2.3 km)
[2]
Mark breakdown: 1 mark for correct method (Pythagoras or scale measurement), 1 mark for correct answer with unit.

(d) 1 : 107 (accept 1 : 100 to 1 : 115)
Working:

Vertical difference (rise) = 52 m – 20 m = 32 m
Horizontal distance (run) = distance between 3063 and 3161 = 1 km = 1,000 m (adjacent grid squares east-west)
Gradient = rise / run = 32 / 1000 = 1 / 31.25 → 1 : 31? Wait — 3063 to 3161 is diagonal? 3063 (easting 30, northing 63) to 3161 (easting 31, northing 61): ΔE = 1 km, ΔN = 2 km. Horizontal distance = √(1² + 2²) = √5 ≈ 2.236 km = 2,236 m.
Gradient = 32 / 2236 ≈ 1 / 69.9 → 1 : 70
Revised answer: 1 : 70 (accept 1 : 65 to 1 : 75)
[2]
Mark breakdown: 1 mark for correct rise (32 m) and run calculation, 1 mark for correct ratio format.

Common mistake: Using grid square distance as 1 km instead of measuring actual horizontal distance between points. Always measure map distance and convert using scale.

Question 2

(a) The hill in grid square 3063 is conical with a steep, symmetrical slope.
Evidence:

Contour lines form concentric circles (closed loops) indicating a hill.
Contours are closely spaced (interval 10 m, multiple contours within one grid square), showing steep slopes.
The pattern is roughly circular and evenly spaced on all sides, indicating a symmetrical, conical shape.
Spot height 52 m at the centre confirms the summit.
[3]
Mark breakdown: 1 mark for shape (conical/circular), 1 mark for steepness (closely spaced contours), 1 mark for map evidence (concentric circles, spot height).

(b) Disagree. The hill has a convex slope, not concave.
Explanation:

Convex slope: Contour lines are closely spaced at the bottom and widely spaced at the top (gentler near summit).
Concave slope: Contour lines are widely spaced at the bottom and closely spaced at the top (steeper near summit).
On the map, contours in 3063 are evenly spaced or slightly closer together at lower elevations (near 30–40 m) and wider near the summit (50 m), indicating a convex profile.
A concave slope would show the opposite pattern.
[2]
Mark breakdown: 1 mark for correct disagreement, 1 mark for correct explanation using contour spacing evidence.

Question 3

(a) Cross-section plot points:

X (2862): 30 m
2962: 40 m
3062: 30 m
3162: 20 m
Y (3262): 10 m

Graph: Points plotted accurately and joined with a smooth curve (not straight lines) to show the undulating terrain.
[3]
Mark breakdown: 1 mark for all 5 points plotted correctly, 1 mark for smooth curve connecting points, 1 mark for correct labelling of axes/points.

(b) Vertical Exaggeration (VE) = 20 times
Working:

Horizontal scale: 1 cm : 1 km = 1 : 100,000
Vertical scale: 1 cm : 50 m = 1 : 5,000
VE = Horizontal scale denominator / Vertical scale denominator = 100,000 / 5,000 = 20
Or: VE = (Vertical scale ratio) / (Horizontal scale ratio) = (1/5,000) / (1/100,000) = 20
Answer: 20× (or "20 times")
[2]
Mark breakdown: 1 mark for correct formula/identification of scales, 1 mark for correct calculation and answer.

Note: Vertical exaggeration makes slopes appear steeper than reality. A VE of 20× means the cross-section shows slopes 20 times steeper than actual.

Question 4

(a) South-east (or south-easterly)
Reasoning: Rivers flow from higher to lower ground. The river enters the reservoir at the north-western corner. The land is higher to the north-west (contours show higher elevation inland) and lower at the reservoir. Flow is towards the reservoir → south-east.
[1]

(b) Two reasons:

Environmental/Aesthetic value: Reservoir edges offer scenic views, greenery, and water access, enhancing recreational experience for cyclists and pedestrians.
Land use efficiency: Built-up areas have high land competition (housing, roads, industry). Using the reservoir fringe (often protected catchment land) avoids displacing urban development and utilises existing green corridors.
Alternative valid reasons: Safety (separated from vehicular traffic), ecological connectivity (linking green spaces), floodplain management.
[3]
Mark breakdown: 1 mark per valid reason with brief explanation (max 2), 1 mark for geographical terminology/context.

Section B: Graph & Data Interpretation [18 marks]

Question 5

(a) December (285 mm)
[1]

(b) 2.2 °C
Working: Highest temp = 28.5 °C (May), Lowest temp = 26.3 °C (Dec). Range = 28.5 – 26.3 = 2.2 °C.
[1]

(c) Rainfall bars plotted on climate graph:

Bars drawn for each month with heights corresponding to rainfall values (e.g., Jan 210 mm, Dec 285 mm).
Bars should be equal width, touching, and coloured/shaded differently from temperature line.
All 12 months plotted accurately.
[3]
Mark breakdown: 1 mark for correct bar heights (allow ±5 mm), 1 mark for correct bar format (touching, equal width), 1 mark for all months completed.

(d) Inverse relationship — months with higher rainfall tend to have lower temperatures, and vice versa.
Evidence: Nov–Dec (high rainfall ~255–285 mm) have lowest temperatures (26.3–26.8 °C). May–Jun (lower rainfall ~145–170 mm) have highest temperatures (28.3–28.5 °C).
[2]
Mark breakdown: 1 mark for identifying inverse/negative relationship, 1 mark for supporting with data examples.

(e) North-east Monsoon (December–March) brings moisture-laden winds from the South China Sea, causing prolonged widespread rain in November–December.
Alternative: Inter-Monsoon period with increased convection and Sumatra squalls.
[1]

Question 6

(a) 560 million gallons per day
Working: 320 + 210 + 30 = 560.
[1]

(b) 16.7% (accept 16.6–16.7%)
Working: Increase = 210 – 180 = 30. % increase = (30 / 180) × 100 = 16.67% ≈ 16.7%.
[2]
Mark breakdown: 1 mark for correct increase (30), 1 mark for correct % calculation and answer.

(c) Yes, target met.
Working: Water losses in 2020 = 30 mgd. Total consumption = 560 mgd. % losses = (30 / 560) × 100 = 5.36%.
Wait — 5.36% > 5%, so target NOT met.
Correct answer: No, target not met (5.36% > 5%).
[2]
Mark breakdown: 1 mark for correct % calculation (5.36%), 1 mark for correct conclusion with comparison to 5%.

Common mistake: Forgetting to multiply by 100 for percentage, or misreading "below 5%" as "5% or below".

(d) Water Efficiency Management Plan (WEMP) — mandatory for large non-domestic users to submit water use data and efficiency measures.
Or: Water pricing — tiered tariffs encourage conservation.
Or: Mandatory water recycling for new developments (e.g., NEWater use in industry).
[2]
Mark breakdown: 1 mark for naming a specific strategy, 1 mark for brief explanation of how it reduces demand.

Question 7

(a) 22.6%
Working: Motorcycles at Junction A = 65. Total at A = 288. % = (65 / 288) × 100 = 22.569% ≈ 22.6% (1 d.p.).
[2]
Mark breakdown: 1 mark for correct fraction (65/288), 1 mark for correct percentage to 1 d.p.

(b) Divided bar graph (100% stacked):
Junction A percentages:

Cars: (185/288)×100 = 64.2%
Motorcycles: 22.6%
Buses: (12/288)×100 = 4.2%
Lorries: (18/288)×100 = 6.3%
Bicycles: (8/288)×100 = 2.8%

Junction B percentages:

Cars: (42/93)×100 = 45.2%
Motorcycles: (28/93)×100 = 30.1%
Buses: (3/93)×100 = 3.2%
Lorries: (5/93)×100 = 5.4%
Bicycles: (15/93)×100 = 16.1%

Graph: Two bars of equal height (100%), each divided into 5 segments proportional to percentages. Legend included.
[3]
Mark breakdown: 1 mark for correct % calculations (allow rounding), 1 mark for accurate segment proportions, 1 mark for legend and labels.

(c) Junction A (main road) is dominated by cars (64%), while Junction B (side road) has a higher proportion of motorcycles (30%) and bicycles (16%).
Or: Main roads carry more through-traffic (cars, lorries, buses); side roads serve local access with more two-wheelers.
[1]

(d) 30 minutes may not represent daily traffic patterns — peak/off-peak variations, day-of-week differences, or weather effects are missed.
Or: Small sample size leads to unreliable averages; unusual events (accident, roadworks) could skew data.
[1]

Section C: Data Analysis & Geographical Skills [12 marks]

Question 8

(a) Negative correlation — as population density increases, green space per person decreases.
[1]

(b) Outlier: Estate B (8,000 persons/km², 25 m²/person).
Reason: Estate B may have large parks, nature reserves, or golf courses within its boundary that inflate green space per person despite moderate density.
Or: Recent development with planned green buffers; data error; unique zoning (e.g., military land, cemetery).
[2]
Mark breakdown: 1 mark for identifying B, 1 mark for plausible geographical reason.

(c) ≈ 13 m²/person (accept 12–14 m²)
Method: Locate 16,000 on x-axis, read up to trend line, read across to y-axis → ~13 m².
[1]

(d) Higher density = more people per unit area. Land is scarce and expensive, so it is prioritised for housing, transport, and commercial use. Green space is "competed away" — less land allocated per person. High-rise living reduces ground-level green access. Planning standards (e.g., 0.8 ha/1000 people) are harder to meet in dense areas.
[2]
Mark breakdown: 1 mark for land scarcity/competition idea, 1 mark for link to planning or per-capita reduction.

Question 9

(a) Bishan (22%)
[1]

(b) Concentrated in mature estates (central and northern areas: Bishan, Marine Parade, Bukit Panjang) with lower percentages in newer towns (Woodlands, Jurong West, Tampines).
Pattern: Inverse relationship with town age — older estates have higher elderly shares due to "ageing in place" and fewer young families moving in.
[2]
Mark breakdown: 1 mark for identifying concentration in mature estates, 1 mark for linking to town age/new vs. old towns.

(c) Two reasons:

Ageing in place: Residents bought flats in mature estates (e.g., Bishan, Marine Parade) decades ago and remained, while younger generations move to newer towns (e.g., Punggol, Sengkang).
Fewer new housing launches in mature estates limit inflow of young families; newer towns attract young couples with BTO flats.
Alternative: Better healthcare access in central areas; proximity to grown children.
[2]
Mark breakdown: 1 mark per valid reason with geographical context.

(d) Challenge: Increased demand for elderly-friendly infrastructure and healthcare.
Explanation: Need for barrier-free access, community care facilities, senior activity centres, and accessible public transport. This requires retrofitting existing estates (costly) and reallocating land from other uses. Also, shrinking workforce in these areas affects local economy.
[2]
Mark breakdown: 1 mark for identifying a specific challenge, 1 mark for explaining planning implication.

Question 10

(a) Females (0.7%) outnumber males (0.4%) in the 85+ age group — more elderly women than men.
[1]

(b) 38.9 (accept 38.9–39.0)
Working:

Young dependents (0–14) = 12.5%
Old dependents (65+) = 15.5%
Total dependents = 12.5 + 15.5 = 28.0%
Working age (15–64) = 72.0%
Dependency ratio = (28.0 / 72.0) × 100 = 38.89 ≈ 38.9
[2]
Mark breakdown: 1 mark for correct total dependents (28.0%), 1 mark for correct formula and answer.

(c) Narrow base = low birth rate → fewer young people entering workforce in future.
Implication: Labour shortage, rising dependency ratio, pressure on CPF/tax base to support ageing population. May require foreign talent, automation, or raising retirement age.
[2]
Mark breakdown: 1 mark for linking narrow base to low birth rate/future workforce decline, 1 mark for specific implication (labour shortage, economic pressure, policy response).

(d) Pro-natalist policies (e.g., Baby Bonus, extended parental leave, subsidised childcare) to encourage higher birth rates.
Or: Silver Economy initiatives (retraining seniors, raising retirement age).
Or: Immigration policy (calibrated foreign workforce).
