2. Curved face to reflect wave energy.
3. Vertical or steep slope.
Marks: [1] per feature, max [2]. Must be observable in the photo.

(c) Negative Impact

Answer:
- Reflects wave energy, increasing erosion at the base of the wall or adjacent areas (terminal groyne syndrome if groynes).
- Unsightly visual impact on natural coastline.
Marks: [1] for identifying impact; [1] for explanation of process/consequence.

Section B: Graph Construction and Data Representation

Marks: [1] for correct subtraction; [1] for correct answer with unit (mm).

(c) Seasonal Pattern Description

Answer: Rainfall is higher in the beginning and end of the year (Jan, Feb, Nov, Dec) and lower in the middle of the year (Jun, Jul). There is a distinct dry season in mid-year.
Marks: [1] for identifying high/low periods; [1] for using data values to support description.

4. Tourist Origin Data

- [1] for title and/or key.

Section C: Statistical Analysis and Fieldwork Data

5. Fieldwork Data

(a) Hypothesis

Answer: Pedestrian footfall decreases as distance from the city centre increases. (Or inverse relationship).
Marks: [1] for clear statement of relationship.

(b) Relationship Description

Answer: As distance increases from 0.5km to 12.0km, the number of pedestrians per hour decreases from 1,200 to 100. The decrease is rapid initially and then slows down.
Marks: [1] for general trend; [1] for use of specific data pairs to support.

(c) Systematic Sampling Method

Answer: Count pedestrians for a fixed time interval (e.g., 5 minutes) every 15 minutes at Location A. OR Count every 10th person passing a specific point.
Marks: [1] for describing the regular interval/method; [1] for applying it to the context (Location A).

(d) Reliability Issue at Location E

Answer: Lower footfall (100/hr) means small changes in count have a larger percentage error. OR Weather conditions might vary more in outer suburbs affecting consistency. OR Shorter counting duration due to safety/time constraints.
Marks: [1] for identifying reason; [1] for explaining impact on reliability.

6. Scatter Graph Analysis

(a) Correlation

Answer: Positive correlation.
Marks: [1].

(b) Anomaly

Answer: Identify the point that does not fit the trend (e.g., high income but low car ownership). Reason: Maybe they live in CBD with good public transport, or environmental consciousness.
Marks: [1] for identification; [1] for plausible reason.

(c) Graph Choice Justification

Answer: Scatter graphs show the relationship/correlation between two continuous variables (income and car ownership). Bar charts are for categorical data.
Marks: [1] for mentioning relationship/correlation; [1] for contrasting with bar chart limitations.

Section D: Synthesis and Evaluation of Data

7. Air Quality and Health Data

(a) Worst Air Quality

Answer: Thursday (AQI 135).
Marks: [1].

(b) Relationship Description

Answer: Generally, as AQI increases, respiratory admissions increase. For example, on Thursday (highest AQI), admissions were highest (32).
Marks: [1] for trend; [1] for data evidence.

(c) Evaluation of Statement

Answer:
- Agree: There is a strong positive correlation; peaks match.
- Disagree: Correlation does not prove causation. Other factors (flu season, temperature) could cause admissions. On Friday, AQI dropped but admissions remained relatively high (20), suggesting lag effect or other causes.
- Conclusion: The statement is too absolute ("all"). Data supports a link, but not exclusive causation.
Marks: [3]
- [1] for acknowledging the correlation.
- [1] for identifying limitations/alternative explanations.
- [1] for balanced conclusion judging the extent of truth.

8. Urban Land Use Map

Answer:
1. Located near highway/port (transport links for goods).
2. More space available/cheaper land rent than city centre.
3. Away from residential areas (reduces noise/pollution impact).
Marks: [1] per valid point linked to map evidence, max [3].

(c) Park Location Justification

Answer:
1. Zone 2 is likely residential; park provides recreational space for residents.
2. Improves air quality/green lung in dense urban area.
3. Reduces urban heat island effect.
Marks: [1] per valid sustainability benefit linked to location, max [3].
