b)
The ideas covered are
- branding / get a sponsor, e.g. a shoe company
- health benefits of walking
- health problems, e.g. sitting down too long
- close public transport for one day
- video of people's feet
- walking and talking (possibly viral video)
- charity campaign
- use a celebrity
c)
They reject
- branding / get a sponsor → want a wider campaign; don't want the campaign linked to a particular company
- health benefits of walking → a bit obvious it's been done before, it's boring and expensive
- health problems → people have been told about the dangers for years, not effective
- close public transport for one day → unrealistic, transport companies wouldn't agree, they'd lose too much money
They chose a combination of
- video of people's feet and use a celebrity
- The charity campaign is not discussed any further.
