My teacher taught me that for the 14 mark question, Knowledge Application and Analysis is worth 8 marks, so if you are able to give definitions, apply it to the question and analysis it, if need be, you can give a graph and analyse that. For the evaluation just say why the methods wont work and criticise them. This can be used for the 10 marks also. For the 4&6 marks just use knowledge application and analysis and you should be fine.
