2 Anglican High School Humanities Department 2022 2236/01/S4 PRELIMINARY EXAMINATION /2022 Section A This question is compulsory. 1 A group of students from a school in Da Nang, Vietnam conducted a geographical field investigation at the coastal city where tourism is the main economic activity. Photograph A Source: Google Map (a) Photograph A shows the location of the beach where the students are interested t o find out whether wave frequency affects beach gradient. The students marked out 2 locations, X and Y on the beach and conducted the investigation on the s ame day. Wave frequency was collected in the morning for Location X and in the afternoon for Location Y. Table 1 Waves per minute Location 1st reading 2nd reading 3rd reading X 7 7 7 Y 5 6 7 (i) Suggest a suitable hypothesis to conduct the investigation. [1] - The higher the wave frequency, the steeper the beach gradient. (or vice versa) (ii) Using Table 1, comment on the type of waves that occurred at location X and Y and its impact on the beach gradient. [3] - Based on average of 7 at Location X and 6 at Location Y - Waves are considered constructive - Less erosive power - Likely result in gentler gradient at both X and Y X Y

3 Anglican High School Humanities Department 2022 2236/01/S4 PRELIMINARY EXAMINATION /2022 (iii) Suggest two improvements to the students’ investigation which can lead to more reliable results. [2] - Can increase scope o f collection to 4 -5 locations along the beach for better representation - Can increase frequency of data collection to span of 1 week (any reasonable days) to get more averages for wave frequency /account for weather changes on other days - Both locations sh ould be done on the same timing to ensure consistent/fair comparison of data (b) The group of students made a trip from Da Nang to Hoi An. They visited the Hoi An Ancient Town at Tran Phu St as shown in Fig. 1 (Insert 1), which showcases Vietnam’s heritage and culture. The students wanted to find out if the types of shops at Hoi An Ancient Town is influenced by the large number of tourists. Fig. 1 Describe a suitable method the students could use to find out the types of shops along Tran Phu St [4] - On a blank sheet of paper, mark out the main street Tran Phu St - From the starting point (which should be at one end of the assigned street), start walking down and ob
