Answer all questions. 1 Cluster 1: Geography in Everyday Life A group of students in the United Kingdom wanted to investigate causes of air pollution in their city area and residents’ opinions on strategies taken to reduce it. They went to the city area on a weekday and used a closed-ended questionnaire survey to collect the views of the residents. They divided themselves into two groups, with one group interviewing the first 50 residents who are less than 50 years old and the other group interviewing the first 50 residents who are above 50 years old. Each group of students interviewed 50 residents. They conducted their questionnaire at the location labelled X shown in Fig.1.1. A copy of their questionnaire is in Fig. 1.2 (Insert). Land use map of the city area in the United Kingdom Key: Household goods store Supermarket Convenience goods store C Specialist store non-food (e.g. florist, travel agent) Sp Personal services (e.g. hairdresser, nail parlour) P Charity shop Ch Cafe CE Offices O Vacant shop space V Fig. 1.1 (a) Explain the advantages and a safety concern of conducting their questionnaire at location X. [3]

2 ● One advantage would be a high footfall /pedestrian traffic at location X as it leads to the bus station so students would be able to get respondents more easily. ● They would also be able to seek shelter at the bus station if it rains. ● It may not be very safe for the students as they are standing at a small road at the entrance / exit to the bus station and accidents may happen . (b) The students collected information on the types of air pollution and their origin. They represented the information in a comparative bar graph. Table 1.1 shows the information collected by the students and Fig. 1.3 shows their partially completed graph.
