2 2279/Sec3EOY/2023 Answer all questions. 1 Cluster 1: Geography in Everyday Life (a) A class of students from a Singapore school wanted to test the hypothesis: ‘When Singaporeans have good knowledge of global warming, they are more willing to take action to combat global warming.’ To do this, they decided to devise a close-ended questionnaire. The draft questionnaire after one round of class discussion is shown in Fig. 1 (Insert). (i) The students thought that further changes can be made to improve the questionnaire. Using Fig. 1, identify the issues with some of the questions and suggest improvement to them. [4] • Q1 on where students live is irrelevant to the hypothesis. Not about knowledge of global warming or willingness to combat global warming. • Hence should be removed from the questionnaire or replace with another question that would check how much knowledge know about global warming. [additional mark] • Q5: Insufficient response options being provided for the action that people can take. Only 3 provided • Provide more options and include an open-ended option on ‘others’ so that people can indicate in writing what other action that they would take [additional mark] • Q4 is about actions that can be taken by the country but the hypothesis is about actions that can be taken by Singaporeans • Change question to be actions that can be taken by Singaporeans • Q4: Students may not understand some of the terms like ‘mitigate’ and ‘adapt’ so they give inaccurate responses • Include a brief explanation of the terms in the questionnaire [additional mark] (ii) Describe a suitable graph they could use to show the data collected using Question 2 from the questionnaire in Fig. 1 (Insert 1).[3] • Pie chart • Create a legend for the 4 responses • Indicate the percentage OR • Bar graph • x-axis is the level of response • y-axis is the number of people (iii) The students decided to conduct the interview in Orchard Road, a popular shopping district in Singapore. Explain how the students could sample visitors to collect the data needed to test the hypothesis. [4] • Conduct systematic/simple random sampling to select the respondents to remove

(b) From 2021 to 2022, there has been increased disaster management efforts to educate Singaporeans on how to prevent fire hazards. The students wanted to test the hypothesis, ‘Increased education efforts from 2021 to 2022 will reduce the occurrences of fire hazards in Singapore during that period’. They obtained data from the news release of Singapore Civil Defence Force (SCDF) to aid their investigation. Study Figs. 2 and 3 (Insert 1), which show the breakdown of fires in non-residential areas and top two types of fires in residential buildings. (i) Using Fig. 2, compare the occurrences of fire between 2021 and 2022 in non- residential buildings. [4] Similarity • Fire occurrences has increased between 2021 to 2022 for all the premises Difference • Higher increase for commercial and industrial premises • 4.2% for commercial premises and 6.9% for industrial premises [additional mark] • Lower increase of 1.4.% for social and communal premises [not to double award ‘lower’, award for evidence] (ii) Using Figs. 2 and 3, evaluate how well the data supports the hypothesis. [5] • Hypothesis is not true • Increase of fires for all non-residential buildings from 1.4% to 6.9% (award maximum of 1 mark since the answer was written in (i) • Large increase in fires caused by electrical • by 18.8% [additional mark] • However, one set of data support the hypothesis. • Reduction in fires caused by unattended cooking • By 4.2% [additional mark] Award a maximum of 3 marks to each set of answer on whether support or do not support the hypothesis.

4 2279/Sec3EOY/2023 2 Cluster 1: Geography in Everyday Life (a) Study Fig. 4 (Insert), which shows the percentage of e-commerce sales in Singapore in 2015 and the projected percentage in 2025. With reference to Fig. 4, suggest why the number of services in a town centre may change over time. [3] • The number of services being offered may decline. • Due to lower demand as many people turn to buy what they need through online platforms. • Should there be an increase in population, more services especially those offering essential services such as food will increase to cater to the increase in demand. (b) Study Fig. 5 (Insert), which shows the distribution of dengue outbreak in Singapore in 2020. Fig. 6 (Insert), shows the distribution of town councils in Singapore. Using Figs. 5 and 6, describe the distribution of dengue outbreak in Singapore in 2020.
