TuitionGoWhere Practice Paper Answer Key — Geography Secondary 2 (Version 4)
Total Marks: 40
Section A: Map Reading (12 marks)
Q1. [1] Grid reference: 1222
Teaching note: Read easting (left edge of square = 12) first, then northing (bottom edge = 22). Four-figure grid reference uses the bottom-left corner of the square containing the feature.
Q2. [1] Six-figure: 132222 (hospital at easting 13.2, northing 22.2 approx.)
Teaching note: Divide square into tenths; 132 = 13 + 0.2 easting, 222 = 22 + 0.2 northing.
Q3. [1] River (or named feature at 1323 per map)
Teaching note: Locate grid square 13 easting, 23 northing.
Q4. [1] North-east (based on river position relative to school)
Teaching note: Use compass rose; river is up-right from school.
Q5. [2] Actual distance = 2 cm × 500 m/cm = 1000 m = 1.0 km
Marking: 1 mark for method (2×500), 1 mark for answer 1.0 km.
Common mistake: forgetting to convert m to km.
Q6. [2] (i) Easting (horizontal location) (ii) Northing (vertical location)
1 mark each.
Q7. [4] Grid references give precise location; allow communication without ambiguity; help in map reading; used in fieldwork to record sites.
Marking descriptors: 1 mark per valid point (max 4). Example: "They allow a geographer to state exactly where a feature is using numbers, which is clearer than words."
Section B: Graph & Data Interpretation (16 marks)
Q8. [2] Rainfall decreased from 120 mm in Jan to 25 mm in Jul; overall declining trend / dry season by mid-year.
Marking: 1 mark trend, 1 mark reference to stats.
Q9. [2] Decrease = (120−25)/120 × 100 = 79.17% ≈ 79%
Working: (95/120)×100. 1 mark working, 1 mark answer.
Q10. [3] Urban population rose from 30% (1980) to 75% (2020), more than doubling; steady increase each decade.
Marking: 1 mark start/end, 1 mark trend, 1 mark statistic.
Q11. [1] 45% (75−30)
Q12. [1] Total = 12+5+3+4 = 24 km²
Q13. [2] % housing = 12/24 × 100 = 50%
1 mark working, 1 mark answer.
Q14. [2] Table shows most land for housing; little park means less green space; geographer can assess balance for sustainability.
1 mark per point.
Section C: Photograph & Data Synthesis (12 marks)
Q15. [2] (i) Dense makeshift structures (ii) Narrow paths / no drainage
1 mark each.
Q16. [2] Poor sanitation due to no drainage leads to health problems.
Marking: 1 mark problem, 1 mark link.
Q17. [2] (i) Local catchment (40%) (ii) Imported (25%)
1 mark each.
Q18. [1] 20%+15% = 35%
Q19. [3] Multiple sources reduce reliance on one; improve water security; match local conditions (e.g., sea for desal).
1 mark each.
Q20. [2] Urban area warmer (urban heat island); 4°C higher than rural.
1 mark observation, 1 mark concept.
