A thesis should be created for Mod C like it is for AOS... take something about 'people and landscapes', for example...
' People and landscapes are inextricably linked '
As a basic example, and then talk about HOW art of travel represents this within the text... for example
'Alain de Botton, in his multi-modal ponderance upon human travel, explores the fact that people and various landscapes are inextricably linked' And then go into the chapter that you're discussing to prove that
Hope this helps a little!
