Award [1] for the factor and a further [1] for development / explanation/exemplification.
For example: A basketball stadium needs to be easily accessible to supporters[1]; this favours a central urban area with good transport accessibility [1].
Other factors include, but are not limited to:
- land availability
- cost of land
- car parking
- noise
- population density
- culture and history
- government and private investment.
Award [1] for each relevant explanation/exemplification point.
For example: Gender equality rights are being legally enforced [1]; this results in changing attitudes and mindsets towards women in sport [1]; women are more empowered to participate in sport, for example, in the FIFA World Cup [1].
Award [1] for each relevant explanation/exemplification point.
For example: Civil society organizations [1] are working with poor communities by providing equipment and access to facilities [1], such as youth rugby in townships in South Africa [1].
Examiners report
Few got this correct as the reading of triangular graphs proved tricky for most.
Most got this correct.
Most were able to find one factor (eg land value, accessibility) but some did not develop it sufficiently.
This was well answered with good explanation about gender equality rights.
Few could back up their explanation with evidence. There were a lot of general comments regarding more time and money.
