Social organisation / Human ingenuity
Appropriate text type?
Appropriate: Interview … the focus of the task is on the conversation itself and how it developed – this includes the central ideas, but not exclusively. In addition, making “this person’s ideas clear to a wide public” indicates some form of journalistic writing.
Generally appropriate: Essay … this form might be generally appropriate for dealing with the central ideas, but we are more concerned with what one person says, rather than with some objective overview (which would indeed require an essay)
Inappropriate: Set of guidelines … the task gives no indication of to whom such guidelines might be addressed – to teachers planning courses? to other business leaders?
