Version 4 of 5
Total marks: 60
SECTION A: Map Skills and Interpretation
[Total: 20 marks]
1. (a) 16 37 (accept 16 36 to 16 38 if trig point is plotted slightly differently) [1]
Note: Four-figure grid reference gives easting first (16), then northing (37).
(b) Working:
- Difference in eastings: 16 − 14 = 2 cm (or 2 grid units)
- Difference in northings: 38 − 36 = 2 cm (or 2 grid units)
- Using Pythagoras: distance on map = √(2² + 2²) = √8 ≈ 2.83 cm [1 for method]
- At scale 1:50,000, 1 cm = 0.5 km, so: 2.83 × 0.5 = 1.415 km [1 for scale conversion]
- Answer: 1.4 km (accept 1.41–1.42 km) [1]
Common error: Forgetting to convert from map distance to ground distance using the scale, or giving answer in cm/m only.
(c) Marking descriptors:
- Level 3 (3–4 marks): Detailed description using multiple map evidence types. Identifies at least two relief features (e.g., river valley with steep sides, coastal plain, higher ground to inland) with specific contour evidence.
- Level 2 (1–2 marks): General description with some map evidence, or detailed description limited to one aspect.
- Level 1 (0 marks): Vague or no map evidence used.
Sample answer for 4 marks: The area shows varied relief. The central river valley is shown by V-shaped contour lines bending upstream (higher values), indicating the land rises away from the river on both sides [1]. The coastal area near Bayfield has widely spaced contours, indicating a gentle gradient or coastal plain [1]. To the north-west, contours rise to the spot height of 156 m, showing higher ground that drains toward the river [1]. The coastline is irregular with a bay, suggesting submergence or erosion of weaker rock [1].
Key concept: Contour spacing indicates slope gradient; contour shape indicates landform.
2. (a) Low pressure system / depression / cyclone [1]
Not acceptable: "Typhoon" (no eye shown) or just "L" without naming the system type.
(b) Marking descriptors:
- Level 3 (3–4 marks): Clear explanation using pressure data and wind patterns to explain contrasting weather. Links Singapore's position to ITCZ/low pressure influence and Hong Kong's position to high pressure/colder conditions.
- Level 2 (1–2 marks): Partial explanation with some map evidence, or explanation of one location only.
- Level 1 (0 marks): Generic or irrelevant answer.
Sample answer for 4 marks: Singapore (1008 hPa, 27°C) is located near the ITCZ and the low pressure centre [1], where converging winds rise, causing cloud formation and rainfall [1]. The temperature of 27°C indicates warm, humid conditions with likely convectional rain. In contrast, Hong Kong (1012 hPa, 22°C) is near the high pressure centre and on the cold side of the cold front [1]. The higher pressure and lower temperature (22°C compared to 27°C) suggest cooler, drier, and more stable conditions with winds from the north bringing colder air [1].
Key concept: Pressure systems determine weather; low pressure = rising air, cloud, rain; high pressure = sinking air, clearer skies; fronts bring abrupt weather changes.
(c) Wind direction: South-westerly / south-west (accept south to southwest) [1] Strength: Light to moderate (shown by widely spaced isobars compared to the strong gradient near the low pressure centre) [1]
Evidence required: Must reference isobar spacing or specific isobar values. Bangkok is in a relatively weak pressure gradient between 1004 and 1008 hPa.
3. (a) Any one valid limitation:
- Choropleth maps use average values across whole countries, hiding internal variations (e.g., rural vs. urban density differences) [1]
- Boundaries are arbitrary political lines, not natural population boundaries [1]
- Colour classes group very different values together, losing precision [1]
- Small countries may be hard to distinguish visually [1]
Key concept: Choropleth maps generalize continuous data into bounded areas, creating the ecological fallacy of assuming uniformity within units.
(b) Three valid push/pull factors with explanatory link:
- Economic pull: Singapore offers high-paying jobs in finance, technology, and services, attracting economic migrants from across Southeast Asia [1]
- Political push/pull: Political instability or conflict in neighbouring countries pushes people toward Singapore's stable governance [1]
- Educational pull: World-class universities and schools attract international students and their families [1]
- Healthcare pull: Advanced medical facilities attract medical tourists and retirees [1]
- Historical/linguistic pull: Existing ethnic Chinese, Malay, and Indian communities create network migration effects [1]
Any three well-developed factors with clear push/pull identification and Singapore-specific link: 3 marks.
SECTION B: Graphical and Data Skills
[Total: 24 marks]
4. (a) January (and February, both 28°C) [1]
Accept "January and February" or either month. Temperature values are equal at 28°C.
(b) Working:
- Sum all monthly rainfall values: 320 + 280 + 200 + 60 + 20 + 5 + 2 + 5 + 10 + 40 + 120 + 250 [1 for correct method with some values]
- = 1312 mm [1]
Common error: Adding temperature values by mistake, or omitting months. Answer only without working: 1 mark maximum.
(c) Two valid descriptive points:
- Annual temperature range is small / temperatures are consistently high throughout the year [1]
- Slight cooling occurs during June–August (winter months in Southern Hemisphere), with minimum in July (19°C) [1]
Alternative valid point: Bimodal pattern with peaks in January/February and December related to wet season cloud cover effects.
(d) Dry season: June, July, August (accept May–September or any month combination where rainfall <50mm) [1]
Reasoning for 2 marks:
- Rainfall in June (5 mm), July (2 mm), and August (5 mm) is extremely low, all below 10 mm [1]
- This contrasts sharply with wet season months (November–March) where monthly rainfall exceeds 120 mm, with January reaching 320 mm [1]
- These months coincide with the coolest period, suggesting reduced evaporation and possible seasonal wind shift (semi-arid/tropical grassland climate pattern) [1 for extension]
Key concept: Tropical climates may have distinct wet/dry seasons due to seasonal ITCZ movement; Southern Hemisphere winter (June–August) brings drier conditions when sun is north.
(e) One valid response with explanation:
Agriculture / farming: Farmers may struggle with irrigation during June–August when rainfall is minimal (5 mm or less monthly) and temperatures still reach 19–21°C, causing soil moisture deficit [1]. Crop selection must account for this dry period, or irrigation infrastructure is essential [1].
Tourism: The dry season may attract tourists seeking reliable sunshine, benefiting beach and outdoor activities with minimal rainfall interruption [1]. However, water sports dependent on river flows may be affected by low water levels [1].
Hydroelectric power: Reduced river flows during dry season may limit electricity generation from run-of-river schemes [1].
Any valid human activity with explicit climate data link: 2 marks.
5. (a) Working:
- Sum 65+ age groups: 65-69 (2.0 + 2.2 = 4.2%) + 70-74 (1.6 + 1.9 = 3.5%) + 75-79 (1.0 + 1.4 = 2.4%) + 80+ (0.6 + 1.0 = 1.6%) [1 for method with correct grouping]
- = 4.2 + 3.5 + 2.4 + 1.6 = 11.7% [1]
Accept 11.7% or working leading to this. Common error: Using only male or only female values, or including 60-64 group.
(b) Two valid features:
- Narrow base: The youngest age groups (0–4: 5.8% + 5.5% = 11.3%; 5–9: 10.9%) are much narrower than typical for a growing population, indicating below-replacement fertility [1]
- Bulge in upper sections / wide top: The pyramid becomes wider in older age groups relative to younger ones, with females outnumbering males in older ages (e.g., 80+: 1.0% female vs. 0.6% male) [1]
- Steepest sides in middle age groups with gradual rather than sharp narrowing toward top, showing survival to old age [1]
(c) Evaluation marking (4 marks):
Policy A – Increase retirement age:
- Strengths: Immediately retains experienced workers, reduces pension/dependency ratio burden, maintains tax base without requiring 18+ years for new workers to enter labour force [1]
- Limitations: May block promotion opportunities for younger workers; not all older workers can physically/mentally continue; may not address long-term demographic decline if fertility stays low [1]
Policy B – Cash incentives for children:
- Strengths: Addresses root cause (low fertility), potential long-term labour supply increase; supported by evidence that childcare costs deter childbearing [1]
- Limitations: Takes 18+ years for economic impact; expensive for government; may have limited effect if cultural preferences for small families are strong; does not solve immediate labour shortage [1]
Judgment (1 mark available within 4): Policy A more effective short-term; Policy B more effective long-term; combined approach most effective. Must justify with temporal considerations.
Sample 4-mark answer: Policy A is more effective in the short term because it immediately extends working life and tax contributions without waiting for children to grow up [1]. However, it only delays rather than solves the ageing problem [1]. Policy B addresses the root cause but requires 18–20 years before children enter the workforce, by which time the old-age dependency ratio will have worsened dramatically [1]. Therefore, both policies should be implemented together, with Policy A as an immediate measure and Policy B for long-term sustainability [1].
6. (a) Working:
- Change = 8438 − 4426 = 4012 [1 for method]
- Percentage change = (4012 / 4426) × 100 = 90.6% [1]
Accept 90.6% or 90.6 (no penalty for missing % if clear context). Common error: Using 2023 as base year, giving 47.5%.
(b) Southeast Asia [1]
Working: 4125 − 2856 = 1269 (largest absolute increase, though Northeast Asia has largest percentage increase).
(c) Two valid reasons:
- Post-COVID recovery: 2022 had travel restrictions; 2023 saw full reopening of borders and resumption of international travel [1]
- Economic rebound in source regions: Improved economic conditions in Southeast Asia and Northeast Asia increased disposable income for travel [1]
- Singapore's marketing campaigns: Targeted tourism promotion such as "SingapoReimagine" to attract visitors [1]
- Increased flight connectivity: Airlines restored and added routes to Singapore [1]
7. (a) Two valid descriptive points:
- There is a positive correlation between GDP per capita and life expectancy: as GDP per capita increases, life expectancy generally increases [1]
- The relationship is non-linear / shows diminishing returns: at lower GDP levels (below ~US10,000),smallincreasesinGDPbringlargelifeexpectancygains;athigherGDPlevels(above US30,000), further wealth increases bring minimal life expectancy improvements [1]
(b) One valid reason with explanation:
- Lifestyle factors: Japan's diet and health behaviours (lower obesity, traditional diet) may promote longevity despite lower GDP than Singapore [1]
- Healthcare system efficiency: Japan's universal healthcare may deliver better health outcomes per dollar spent [1]
- Income inequality: Singapore's high GDP per capita may mask inequality; average wealth doesn't translate to health access for all citizens [1]
- Social factors: Stronger community and family support networks in Japan may contribute to elderly wellbeing [1]
- Stress and work culture: Singapore's competitive work environment may negatively impact health despite high income [1]
(c) Two valid comparative points:
- A scatter graph shows individual data points as separate entities without implying continuity between them; countries are discrete cases, not a continuous variable [1]
- A line graph would incorrectly suggest a predictable sequence or trend between the plotted points when there is no natural order to countries [1]
- Scatter graphs clearly display correlation patterns and outliers (e.g., Japan vs. Singapore) that line graphs obscure [1]
- Multiple countries can be labelled individually without overcrowding the axis [1]
SECTION C: Data Response and Synthesis
[Total: 16 marks]
8. (a) Marking descriptors:
- Level 3 (3 marks): Detailed description with specific data references showing trend and variability.
- Level 2 (2 marks): General trend described with some data.
- Level 1 (0–1 marks): Vague description or no data.
Sample 3-mark answer: Singapore's rainfall shows high inter-annual variability with no clear increasing or decreasing trend [1]. The highest rainfall occurred in 2021 (3080 mm) and 2016 (3010 mm), while the lowest was in 2018 (1710 mm) and 2015 (1850 mm) [1 for specific data]. The range is approximately 1370 mm between maximum and minimum, indicating unreliable rainfall that challenges water planning [1]. Years alternate between relatively wet and dry without predictable pattern, consistent with equatorial influences and climate variability [1 for extension].
(b) Marking: Must reference BOTH graph AND table for full marks.
4-mark answer structure:
- NEWater and desalination are weather-independent [1]: Table shows local catchment water depends on rainfall (20%, vulnerable to variability shown in graph where rainfall ranged 1710–3080 mm) [1]
- NEWater (30%): Recycles used water, creating a renewable loop not dependent on rainfall; however, energy-intensive [1 from table]
- Desalinated water (10%): Unlimited source from seawater; highest energy cost but completely independent of rainfall variability shown in graph [1 from table]
- Combined importance: Together they provide 40% of supply that is rainfall-independent, crucial as demand rises from 430 to 680 million gallons/day by 2040 while rainfall remains unreliable [1 synthesis using both sources]
(c) Evaluation (5 marks):
Marking descriptors:
- Level 4 (5 marks): Balanced evaluation with clear judgment, considering multiple strengths AND limitations with specific reference to the Four National Taps.
- Level 3 (3–4 marks): Some balance, with developed explanation of either strengths or limitations.
- Level 2 (1–2 marks): One-sided or generic answer.
- Level 1 (0 marks): Irrelevant or no evaluation.
Sample 5-mark answer:
Diversification significantly reduces but does not eliminate vulnerability [1 for qualified judgment].
Strengths:
- Reduces single-source dependency: Imported water (50%) is vulnerable to Malaysia agreement expiry in 2061 and political relations; diversification hedges this risk [1]
- Addresses rainfall variability: Graph shows 1370 mm range in annual rainfall; NEWater and desalination (40% combined) provide stable supply regardless of drought [1]
- Scalability: NEWater and desalination can expand capacity unlike land-limited catchments [1]
Limitations:
- Energy vulnerability: Both NEWater and desalination are energy-intensive; rising energy costs or supply disruptions would affect water security [1]
- High costs: Desalination has highest energy cost; scaling to 100% would be economically unfeasible [1]
- Incomplete replacement: Even with diversification, 20% local catchment and 50% imports remain vulnerable to climate and geopolitical factors [1]
- Environmental impacts: Desalination brine disposal affects marine ecosystems; NEWater requires sophisticated treatment infrastructure [1]
Judgment: The Four National Taps strategy is necessary but insufficient alone; Singapore must also pursue demand management, water conservation, and renewable energy to fully secure water supply [1]
9. (a) Hard engineering / groynes and sea wall (accept either or both) [1]
(b) 3-mark explanation:
Groynes are perpendicular structures built from coastline into sea [1]. They trap sediment moving by longshore drift, preventing it from being carried away from the beach; this builds up beach width which absorbs wave energy [1]. The sea wall provides a physical barrier that reflects wave energy back to sea, preventing direct erosion of the coastline behind it [1].
(c) Advantage (1 mark): Immediate and predictable protection; long lifespan; effective against severe storms; protects infrastructure directly behind [1]
Disadvantage (1 mark): More expensive to construct and maintain than beach nourishment; groynes starve downdrift beaches causing erosion elsewhere; sea walls reflect wave energy that scours beach material; visual/ environmental impact on natural coastline; cannot adapt to sea level rise unlike ecosystem-based approaches [1]
