TuitionGoWhere Exam Practice (AI) - Geography O-Level Practice Paper Answer Key (Version 5)
Subject: Geography
Level: O-Level
Topic: Map, Graph & Data Skills
Total Marks: 60
Section A: Graph and Data Representation
Q1 [3 marks]
- Suggested answer: Use a line graph with months (Jan–Jun) on the x-axis and rainfall (mm) on the y-axis; plot 4 lines (one per station) with a legend identifying Woodlands, Tampines, Jurong, Bedok. (1 mark for graph type, 1 mark for axes/units, 1 mark for overlay/legend)
- Teaching note: Continuous data over time for multiple sites is best as overlaid line graphs to compare trends. Avoid separate graphs (common trap).
Q2 [2 marks]
- Graph: Bar chart. Reason: Data are categorical (days) and show counts; bar chart compares discrete values clearly. (1+1)
- Teaching note: Days are categories, not continuous time series needing line.
Q3 [2 marks]
- X-axis: Time (hours from 6am to 6pm); Y-axis: Temperature (°C). (1 each)
- Teaching note: Line graph needs independent variable (time) on x, dependent (temp) on y.
Q4 [2 marks]
- Assign weights (e.g., SA=+2, A=+1, D=−1, SD=−2), multiply count by weight per category, sum for net score per amenity. (1 method, 1 weighting)
- Teaching note: Net score = Σ(weight×frequency). Template 3.
Q5 [3 marks]
- Overlaid line graph or grouped bar chart; line graph allows trend comparison across sites over time if time-based, or bar for discrete. (1 type, 2 justification/labelling)
- Answer: Use a line graph with wind speed on y, time/site on x, legend for 3 sites.
Q6 [2 marks]
- Bar chart to compare magnitudes; label y-axis "Magnitude", x-axis "Town". (1+1)
Section B: Map and Photograph Interpretation
Q7 [1 mark]
- From contour pattern and sea position, river flows from inland (higher contour) east to coast (lower). Answer: Eastward / to the east.
- Based on Q7-fig1: river from 40 m contour to sea, town west.
Q8 [2 marks]
- East of town: contours 10–40 m show rising relief inland; steep/moderate slope; hill up to 40 m. (1 description, 1 inference)
- From map: contours close = steeper.
Q9 [1 mark]
- July (170 thousand). From Q9-fig1 highest bar.
Q10 [2 marks]
- Jan=100, Jul=170. % increase = (170−100)/100 ×100 = 70%. (1 formula, 1 answer)
- Working: (70/100)*100 = 70%.
Q11 [2 marks]
- Scale 1:25 000 → 8 cm map = 8×25 000 = 200 000 cm = 2 km. (1 calc, 1 unit)
- 200 000 cm / 100 000 = 2 km.
Q12 [2 marks]
- Flat sandy beach; gentle slope to sea; waves at shoreline. (1 each)
- From Q12-fig1.
Section C: Data Analysis and Evaluation
Q13 [2 marks]
- Net = (20×2)+(15×1)+(10×−1)+(5×−2) = 40+15−10−10 = 35. (1 working, 1 answer)
Q14 [4 marks]
- Position: Partially reliable (1).
- Evidence: n=50 is moderate; used clear Likert scale (1).
- Explanation: Weighted scoring reduces bias; but self-report may have subjectivity (1).
- Qualification: While sample adequate, single site limits representativeness (1).
- Template 2 structure.
Q15 [2 marks]
- Axis labels and units; trend line / overall direction; scale. (1+1)
Q16 [3 marks]
- Grouped bar chart: x-axis sites, bars for time 1 and time 2, legend. Or clustered line. (1 type, 2 labelling)
- Allows comparison of noise across sites and times.
Q17 [1 mark]
- Residential (45%). From Q17-fig1.
Q18 [2 marks]
- Green 25% → angle = 25% × 360° = 90°. (1 calc, 1 answer)
- 0.25×360 = 90°.
Q19 [3 marks]
- Line graph: x=distance along channel, y=depth; plot 10 points. (1 type, 2 labels/points)
- Shows variation pattern.
Q20 [4 marks]
- Useful: compares 5 cities' monthly trends; identifies wet/dry months (2).
- Limit: clutter if too many lines; need legend/clear colour (1).
- Conclusion: effective with proper labelling (1).
- Marking: 2 for strengths, 1 weakness, 1 judgement.
