How this question is marked

4 marks, so the mark scheme is looking for about 4 separate creditworthy points. Making the same point twice in different words earns it once.

Discuss means: Set out the points on more than one side and weigh them up. Cover both sides, then finish with a judgement that follows from what you wrote.
