*(Any one valid piece of evidence)*

**(b)** Suggest one limitation of this conclusion.  
**[2 marks]**

**Answer:**
- The data may have been collected on only one day or at one time, which may not be representative of litter patterns at other times. [1] For example, if the fieldwork was conducted on a weekend when the food court was busier, the results may overestimate the amount of litter near the food court compared to a weekday. [1]
- The study may not have considered other factors such as the number of bins available or the proximity of bins to the food court. [1]

*(Any two valid limitation points, 1 mark each)*

*(Award 2 marks for a clear, testable hypothesis that links distance from the factory to air quality)*

**(b)** Suggest one way the students could improve the reliability of their results.  
**[1 mark]**

**Answer:**
- Repeat the measurements at each location multiple times and calculate an average. [1]
- Take measurements on different days to account for varying weather conditions. [1]
- Increase the number of sampling points at different distances from the factory. [1]

*(Any one valid suggestion)*

---

**19.** Evaluate the effectiveness of using observation as a fieldwork method for studying pedestrian movement in a shopping area.  
**[4 marks]**

**Answer:**

*Advantages:*
- Observation allows the researcher to record pedestrian behaviour directly and in real time, providing accurate and authentic data. [1] It does not rely on participants' memory or willingness to cooperate, unlike questionnaires. [1]

*Limitations:*
- Observation can be time-consuming, as the researcher needs to spend extended periods at the site to capture representative data. [1] The presence of the observer may influence pedestrian behaviour (the Hawthorne effect), reducing the validity of the results. [1] It can also be difficult to record large numbers of pedestrians accurately without the aid of technology such as video recording. [1]

*Overall evaluation:*
- Observation is an effective method for studying pedestrian movement because it provides direct, first-hand data. However, its limitations mean it should ideally be combined with other methods (e.g., tally counts, video analysis) to improve accuracy and reliability. [1]

*(Marking: Award up to 2 marks for advantages, up to 2 marks for limitations/evaluation. Maximum 4 marks. Answers should demonstrate balanced evaluation for full marks.)*

---

**20.** Vegetation cover and soil temperature investigation.  
**[5 marks total]**

**(a)** State the conclusion of this investigation.  
**[2 marks]**

**Answer:**
- Areas with more vegetation cover have lower soil temperatures than areas with less vegetation cover. [1] This is because vegetation provides shade and the process of transpiration cools the surrounding soil. [1]

**(b)** Explain why this conclusion is useful for urban planning.  
**[2 marks]**

**Answer:**
- Urban planners can use this information to design cooler cities by increasing vegetation cover such as parks, green roofs, and tree-lined streets. [1] This can help reduce the urban heat island effect, making urban areas more comfortable for residents and reducing energy consumption for cooling. [1]

**(c)** Suggest one further investigation that could build on these findings.  
**[1 mark]**

**Answer:**
- Investigate whether different types of vegetation (e.g., grass vs. trees vs. shrubs) have different effects on soil temperature. [1]
- Investigate how vegetation cover affects air temperature at different heights above the ground. [1]
- Compare soil temperature differences between areas with vegetation and areas with different surface materials (e.g., concrete, asphalt, bare soil). [1]
