1 [Mayflower Sec] 3E END OF YEAR EXAMINATION 2023 ANSWER SCHEME Answer Question 1 Cluster 1: Geography in Everyday Life 1 A group of students from Mayflower Secondary School investigated the experience of visitors at the Gallop Extension in the Singapore Botanic Gardens. The Gallop Extension is an eight hectare area with many features which aim to bring nature closer to visitors while educating them on Singapore’s forest ecosystems and conservation efforts.

Does the knowledge about the features of he Gallop Extension change as the length of visit to that part of the Gardens increases? How does the length of visit to the Gallop Extension affect the knowledge of it? AO2 [1]

[3] Award 1m for the suggestion of the suitable sampling method and 2m for the description of how it is carried out. Description must include information on where the sampling method is carried out. Possible responses can include: • Students can use a simple random sampling method as it will help to remove the bias that could stem from selection of visitors. [1] • This could be done at either of the entrances of Singapore Botanic Gardens where people enter and exit by so as to approach visitors easily.[1] • This can be done by using a random number table in the selection of visitors at a specific time at the gate [1] AO2 (d) Study Fig. 1.2 which provides descriptions of the different features of the Gallop Extension in Singapore Botanic Gardens.
