TuitionGoWhere Practice Paper (AI) - Version 3 - MARKING SCHEME

Section A: Map Reading Skills [15 marks]

Question 1 [2 marks] (a) Changi Airport: 4079 [1 mark] (b) Singapore Botanic Gardens: 2878 [1 mark]

Marking note: Accept reasonable variations due to map reading precision (±1 grid square)

Question 2 [3 marks] Nature reserves are mainly distributed in the central and northern parts of Singapore Island [1 mark]. The largest concentration is in the central area around grid squares 2878-3079 including Bukit Timah Nature Reserve [1 mark]. Additional smaller reserves are found in the northeast (Sungei Buloh, grid square 3983) and eastern areas (Pulau Ubin vicinity, grid square 4080) [1 mark].

Marking note: Award marks for accurate description with correct grid references. Accept alternative valid grid references.

Question 3 [2 marks] Distance: 14.2 km [2 marks for correct answer within ±0.5km] [1 mark for measurement attempt with minor error]

Marking note: Students should measure straight line and convert using map scale

Question 4 [4 marks] Physical feature 1: Coastal waters/sea/straits [1 mark] Effect: Provides opportunities for fishing and marine transport but may limit land-based development and require boat access [1 mark]

Physical feature 2: Small island/isolated location [1 mark]
Effect: Creates unique tourism opportunities but limits infrastructure development and increases transport costs [1 mark]

Marking note: Accept other valid physical features like beaches, vegetation, hills. Effect must logically relate to the feature identified.

Question 5 [4 marks] The western part of Singapore is suitable for industrial development because:

• Coastal location provides access to shipping and ports for importing raw materials and exporting goods [1 mark]
• Flat terrain (shown by lack of contour lines) makes construction easier and cheaper [1 mark]
• Distance from city center reduces land costs and minimizes conflicts with residential areas [1 mark]
• Good transport links including major roads connecting to other parts of Singapore [1 mark]

Marking note: Accept other valid reasons with map evidence. Must refer to map features.

Section B: Graph and Data Interpretation [20 marks]

Question 6 [2 marks] Working: (12.5 - 8.2) ÷ 8.2 × 100 = 52.4% [1 mark for correct method] Percentage increase: 52.4% [1 mark for correct answer]

Marking note: Accept answers between 50-55% due to graph reading variations

Question 7 [3 marks] Manila's population showed steady growth from 11.5 million in 2000 to 14.8 million in 2020 [1 mark for trend + data]. The growth was consistent throughout the period with no major fluctuations [1 mark]. The total increase was 3.3 million people over 20 years, representing moderate but sustained urban growth [1 mark].

Marking note: Must include specific data. Accept reasonable data variations due to graph reading.

Question 8 [4 marks] Similarities: Both cities experienced continuous population growth from 2000-2020 [1 mark]. Both started with similar populations around 6-7 million in 2000 [1 mark].

Differences: Bangkok's growth was more gradual, increasing from 6.8 to 9.2 million [1 mark], while Ho Chi Minh City grew more rapidly, from 6.1 to 10.4 million, showing steeper growth especially after 2010 [1 mark].

Marking note: Must compare both cities with specific data. Award marks for clear similarities and differences.

Question 9 [3 marks] Informal housing is unevenly distributed across Metro Manila's districts [1 mark]. Highest concentrations are in Tondo (78%) and Payatas (65%) [1 mark]. Lower percentages are found in Makati (12%) and Bonifacio Global City (8%), showing significant variation between districts [1 mark].

Marking note: Must use specific percentages from figure. Accept reasonable data variations.

Question 10 [8 marks] Relationship explanation: Rapid population growth creates increased demand for housing that formal housing supply cannot meet [1 mark]. Figure 1 shows Manila grew by 3.3 million people, creating enormous housing pressure [1 mark]. Figure 2 shows high informal housing percentages in several districts, demonstrating this unmet demand [1 mark].

Causes of relationship:

• Rural-urban migration brings people seeking economic opportunities but with limited income [1 mark]
• Formal housing is expensive and requires legal documentation that migrants may lack [1 mark]
• Government housing programs cannot keep pace with rapid population growth [1 mark]
• Land scarcity in cities forces people to settle on marginal land illegally [1 mark]

Conclusion: The data shows that rapid urbanization without adequate planning leads to informal settlement growth as cities struggle to provide sufficient affordable housing [1 mark].

Marking note: Must link both figures and show understanding of cause-effect relationship. Award marks for clear explanation with evidence.

Section C: Photograph Analysis and Fieldwork Skills [15 marks]

Question 11 [2 marks] Evidence: Dense, self-built structures / Lack of proper roads / Improvised building materials / Overcrowded conditions / Lack of proper infrastructure [2 marks for clear identification]

Marking note: Accept any valid visual evidence that clearly indicates informal settlement characteristics

Question 12 [4 marks] Environmental problem 1: Poor sanitation/waste management [1 mark] Effect: Increases risk of waterborne diseases and creates unhealthy living conditions that affect children's health and education [1 mark]

Environmental problem 2: Air pollution from cooking fires/burning waste [1 mark] Effect: Causes respiratory problems and reduces life expectancy, particularly affecting elderly and children [1 mark]

Marking note: Problems must be visible in photograph. Effects must logically relate to the problem identified.

Question 13 [3 marks] Photograph A shows much higher density with buildings closely packed together and minimal space between structures [1 mark]. Photograph B shows lower density with planned spacing and green areas between buildings [1 mark]. The difference occurs because informal settlements maximize use of limited land while public housing follows planning regulations that require open space and infrastructure [1 mark].

Marking note: Must compare both photographs and provide logical explanation for difference

Question 14 [3 marks] Data collection method: Structured interviews/questionnaires [1 mark] Explanation: This method is suitable because it allows collection of residents' perspectives on housing conditions that may not be visible externally [1 mark]. It can gather standardized data about problems like water supply, electricity, and health issues that can be compared across different areas [1 mark].

Marking note: Accept other valid methods (field sketches, observations, photography) with appropriate justification

Question 15 [3 marks] How to carry out: Select every nth house (e.g., every 5th house) along predetermined routes through the settlement, ensuring coverage of different areas [1 mark]. Start from a random point and maintain consistent intervals [1 mark].

Advantage: Reduces researcher bias because the selection method is predetermined and systematic, ensuring more representative results than convenience sampling [1 mark].

Marking note: Must describe systematic method clearly and provide valid advantage
