Write in dark blue or black pen on both sides of the paper. You may use a pencil for any diagrams or graphs. Do not use staples, paper clips or correction fluid. Candidates answer all questions. The Insert contains all the Resources referred to in the questions. You should make reference to appropriate examples studied in the field or the classroom, even where such examples are not specifically requested by the question. Diagram and sketch maps should be drawn whenever they serve to illustrate an answer. World outline maps will be provided if you request for them. They may be annotated and handed in with the relevant answers. You are reminded of the need for good English and clear presentation in your answers. The number of marks is given in brackets [ ] at the end of each question or part question. Answer every question on a fresh sheet of writing paper.

This paper consists of 4 printed pages including the cover page Page 2 SECTION A Theme 4: Geographical Investigation 1 You and your classmates were tasked to investigate infiltration rates of two sites. You decided to split yourselves into two gr oups of four to meas ure the infiltration rates of soil at each site. Site A is near the river running through Bishan-Ang Mo Kio Park with residential areas approxim ately 400 metres north and south of it. Site B is at a construction site near the junction of Tanglin Road and Grange Road with commercial and residential areas within its 200 metres radius. Together with your classmat es, you made your own double ring infiltrometers with used aluminium milk powder tins. You decided to use the stopwatch function of your smart phones. Infiltration ra tes are calculated by a standardised recording sheet prepared by yourselves. At each site, both groups chose the fla ttest ground possible and clipped off any existing grass before you gently twist your double-ring infiltrometer into the soil. Both groups poured water into the infilt rometers, the water level dropped faster initially and measurements were taken only when all three members decided the fall in water level slowed down. Both groups started at the same time and completed the task in an hour. To ensure accuracy, the groups carried out the same steps the next day. Photographs of the exact pl acement of the infiltromete rs were taken to ensure the same spots were utilised. Resource 1 shows storm hydrographs of Site A and Site B. Resource 2 shows maps with locations of Site A and Site B. Resource 3 shows the consolidated data collected by you and your classmates to calculate infiltration rates. (a) With reference to Resource 1, s uggest a suitable hypothesis for this geographical investigation. [1] (b) Describe three potential risks at Site A shown in Resource 2 and explain how each risk could be minimized. [6] (c) Explain how you would minimize the impact of your investigation at Sites A and B differently. [4] (d) Suggest two limitations of Resource 3 in representing the findings and draw bar graphs to represent the infiltration rates of Sites A and B. [5] (e) Evaluate this investigation to ascert ain the flood risks of Sites A and B, and explain how it could be improved and extended. [9]

This paper consists of 4 printed pages including the cover page Page 3 SECTION B Theme 1: Tropical Environments Plantations in Pahang 2 Pahang is a state in Peninsular Malaysia. Two-thirds of Pahang’s land is forested and 12.8% of the total land area is used for plantation agriculture. Resource 4 is a climograph of Pahang. Resource 5 shows the vegetation structure, soil profile and mean biomass of a typical forest in Pahang. Resource 6 is the water budget of entire Pahang. Resource 7 is a photograph of a tea plantation in a forest of Pahang. (a) Identify the climatic zone of P ahang according to Köppen–Geiger climate classification system. S upport your answer with data from Resource 4. [4] (b) Describe the vegetation structure and mean biomass of a typical forest in Pahang as shown in Resource 5. [3] (c) With the help of Resources 5 and 6, suggest the possible processes that result in the soil profile of a typical forest in Pahang. [6] (d) With reference to Resource 7, explain how the landscape was changed to develop a plantation. [4] (e) Using Resources 4, 6 and 7, explain why occurrence of mass movements is a major concern of plantation owners in Pahang. Support your response with information from the resources. [8]

Resource 9 shows information on the ownership of copper and cobalt mines operating in Katanga Provin ce of the DRC. Resource 10 shows information on the movement of cobalt from mines in the DRC to global markets. (a) Using Resource 8, describe the spatial pattern of resource extraction in the DRC. [3] (b) To what extent does Resource 8 show a core-periphery pattern of development within the DRC. [5] (c) Explain three possible impacts of forei gn ownership of mines as depicted in Resource 9. [6] (d) Describe the global production network of cobalt as shown in Resource 10. [4] (e) Evaluate the usefulness of Resource s 8, 9 and 10 as evidence for the resource curse thesis in the DRC.
