The document below is a tutor-marked assignment question based on the material covered in the Unit 5 extract.

We suggest that you try writing an answer to the question yourself, but don't worry if it seems too difficult, as you haven't had the benefit of the previous 8 weeks of study on the module, together with the accompanying assignments and assistance from a tutor!

After trying the question have a look at the sample solution (based on actual work submitted by students).
