Answers
Answer Key - Geography O-Level Practice Paper 1 (Version 1)
Question 1: Fieldwork and Geographical Methods
(a) Hypothesis [2m]
- Expected Answer: "Noise levels decrease as the distance from the main road increases." (1m for clear relationship, 1m for measurable variables).
(b) Data Representation [3m]
- Graph Choice: Scatter graph or Line graph (1m).
- Justification: A scatter graph allows the students to plot distance on the x-axis and noise level on the y-axis to identify a correlation/trend (2m).
(c) Instrument [1m]
- Expected Answer: Measuring tape / Trundle wheel / GPS.
(d) Reliability Evaluation [4m]
- Position: Partially reliable / Unreliable (1m).
- Evidence: Measuring only at 10:00 AM on a Tuesday is a snapshot (1m). It does not account for peak hour traffic (rush hour) or weekend variations (1m).
- Qualification: However, if the goal was to measure "mid-morning baseline noise," it is consistent (1m).
(e) Weighted Scores [4m]
- Method: Assign numerical weights to categories (e.g., Very Satisfied = +2, Satisfied = +1, Dissatisfied = -1, Very Dissatisfied = -2) (2m).
- Calculation: Multiply the frequency of each response by its weight and sum them to get the net positive/negative score (2m).
(f) Improving Reliability [6m]
- Point 1: Increase sample size (e.g., measure at 30 locations instead of 10) to reduce the impact of anomalies (3m).
- Point 2: Temporal sampling (e.g., measure at different times of the day or different days of the week) to capture a representative average (3m).
Question 2: Tourism
(a) Pull Factors [4m]
- Identification: Specific attraction (e.g., Eiffel Tower in Paris, beaches in Maldives) (1m).
- Explanation: Natural beauty/cultural heritage attracts tourists seeking leisure/education (2m). Infrastructure/Accessibility makes it easier to visit (1m).
(b) Trend Description [3m]
- Overall Trend: General increase with a significant dip (1m).
- Data Reference: Rose from 10k in 2015 to a peak of 40k in 2019 (1m).
- Anomaly: Sharp decline to 5k in 2020 (likely due to pandemic), followed by a recovery to 35k by 2023 (1m).
(c) Evaluation: Sustainable Tourism [8m]
- Agree (3-4m): Prevents environmental degradation (e.g., coral bleaching in Maldives); preserves local culture from "commodification"; ensures economic benefits stay local (pro-poor tourism).
- Disagree/Qualify (3-4m): Some destinations rely on mass tourism for rapid economic growth/poverty alleviation which may be unsustainable in the short term; government priorities may favor infrastructure over ecology.
- Conclusion (1-2m): Balanced judgment. Sustainable tourism is essential for longevity, but must be balanced with economic viability.
Question 3: Climate
(a) Instrument [1m]
- Expected Answer: Barometer / Aneroid Barometer.
(b) Clean Water & Life Expectancy [4m]
- Mechanism: Clean water reduces the spread of waterborne diseases like cholera or dysentery (2m).
- Link: Lowering child mortality rates and reducing adult illness leads to an increase in the average life expectancy of the population (2m).
(c) Evaluation: Climate Change & Food Shortage [10m]
- Agree (4m): Altered rainfall/extreme weather (droughts in Sahel, floods in Pakistan) lead to crop failure and soil degradation, reducing global yields.
- Disagree/Qualify (4m): Other factors: Population growth (demand exceeds supply), Political conflict (Ukraine-Russia war affecting grain exports), Poverty (lack of access to fertilizers/tech).
- Conclusion (2m): Climate change is a "threat multiplier" that exacerbates existing vulnerabilities, but is not the sole cause.
