Answer all questions. 1 Cluster 1: Geography in Everyday Life A group of students were investigating the relevance and popularity of wet markets for sustainable living in Singapore. There are currently 83 wet markets managed by the National Environment Agency (NEA) and NEA-appointed operators in Singapore, compared with 691 supermarkets. The students found data on the NEA website showing the decreasing public preference for wet markets and represented the information using a pie chart, as shown in Fig. 1.1. They decided to test the hypothesis: “Wet markets are becoming increasingly irrelevant in meeting the grocery needs of Singapore residents.” NEA survey results of 1,000 Singapore residents aged 18 to 69 Fig. 1.1 (a) Using Fig. 1.1, suggest how the information is useful for this investigation. ....................................................................................................................................................... ....................................................................................................................................................... © Anglican High School Humanities Department 2025 2279/01/S4 Preliminary Examinations
