Answer: 2.0 °C [2 marks]
Marking note: Award 1 mark for the correct method (subtracting lowest from highest) and 1 mark for the correct answer.
13. Compare the temperature trend from January to May with the trend from June to December. [3 marks]
Answer:
- From January to May, temperatures showed a steady increasing trend, rising from 27.0 °C to a peak of 29.0 °C in May. [1 mark]
- From June to December, temperatures generally decreased from 28.8 °C in June to 27.2 °C in December, with some minor fluctuations (e.g., a slight rise from September to October). [1 mark]
- Overall, temperatures were higher in the first half of the year (peaking in May) and lower in the second half, showing a pattern of warming in the early months followed by gradual cooling towards the end of the year. [1 mark]
Marking note: Award 1 mark for describing the January–May trend with data, 1 mark for describing the June–December trend with data, and 1 mark for a valid comparison of the two periods.
14. Explain why Singapore's temperatures remain relatively high and stable throughout the year. [3 marks]
Answer:
- Singapore is located near the equator (approximately 1°N), which means it receives intense and direct solar radiation all year round. [1 mark]
- The small annual temperature range (only 2.0 °C) is due to Singapore's maritime location – being surrounded by sea, the ocean moderates temperature extremes by absorbing and releasing heat slowly. [1 mark]
- There are no distinct seasons with extreme temperature variations because the equatorial region experiences relatively consistent day length and solar angle throughout the year, unlike countries at higher latitudes. [1 mark]
Marking note: Award 1 mark for each valid explanatory point. Answers should demonstrate understanding of equatorial location, maritime influence, and/or solar radiation. Maximum 3 marks.
Section C: Data Analysis and Application (Questions 15–20) [10 marks]
15. Which planning area had the largest population in 2023? [1 mark]
Answer: Jurong West (272,000) [1 mark]
16. Calculate the population increase for Punggol between 2020 and 2023. [2 marks]
Working: Population increase = Population 2023 – Population 2020 = 195,000 – 175,000 = 20,000
Answer: 20,000 [2 marks]
Marking note: Award 1 mark for the correct method (subtraction) and 1 mark for the correct answer.
17. Calculate the percentage increase in population for Punggol between 2020 and 2023. [3 marks]
Working: Percentage increase = (Population increase ÷ Original population) × 100 = (20,000 ÷ 175,000) × 100 = 0.11428... × 100 = 11.4% (to one decimal place)
Answer: 11.4% [3 marks]
Marking note: Award 1 mark for the correct formula/method, 1 mark for correct substitution of values, and 1 mark for the correct final answer to one decimal place.
18. Which planning area had the smallest population increase between 2020 and 2023? [2 marks]
Working:
- Jurong West: 272,000 – 265,000 = 7,000
- Tampines: 260,500 – 258,000 = 2,500
- Woodlands: 258,000 – 252,000 = 6,000
- Sengkang: 249,000 – 240,000 = 9,000
- Punggol: 195,000 – 175,000 = 20,000
Answer: Tampines (increase of 2,500) [2 marks]
Marking note: Award 1 mark for showing calculations for at least two planning areas and 1 mark for correctly identifying Tampines with the smallest increase.
19. Suggest one reason why Punggol experienced a relatively large population increase. [1 mark]
Answer: Punggol is a relatively new town that has undergone significant development in recent years, with the construction of many new Housing Development Board (HDB) flats and amenities, attracting young families and new residents. [1 mark]
Accept any one valid reason, such as:
- New housing developments / BTO flats
- Improved transport connectivity (e.g., Punggol MRT extension)
- Development of Punggol Digital District / Waterway Town
- Government planning to develop Punggol as a regional centre
Marking note: Award 1 mark for any plausible, geographically valid reason.
20. Evaluate the claim that Jurong West will always have the largest population in Singapore. [3 marks]
Answer:
- The data shows that Jurong West had the largest population in both 2020 and 2023, so the claim is currently supported by the evidence. [1 mark]
- However, the data also shows that Punggol had a much larger percentage increase (11.4%) compared to Jurong West (approximately 2.6%), suggesting that Punggol is growing at a faster rate. If this trend continues, Punggol could eventually overtake Jurong West. [1 mark]
- Additionally, population sizes can change due to government planning decisions, new housing developments, and migration patterns, so it is not certain that Jurong West will always remain the largest. The word "always" makes the claim too absolute and difficult to support with only three years of data. [1 mark]
Marking note: Award 1 mark for acknowledging that the claim is currently true based on the data, 1 mark for identifying evidence that challenges the claim (e.g., different growth rates), and 1 mark for evaluating the use of absolute language ("always") or discussing factors that could change the outcome. Maximum 3 marks.
