How should I structure an essay with the question beginning "How far do you agree..."?

A question beginning with "How far do you agree..." is a blessing in disguise, because it allows you to explore the agreement and the disagreement with the matter in hand.  After your introduction, in which you should display your understanding of the question and state your first judgement on the issue, your first paragraph should state your thesis, i.e. your arguments agreeing.  Following this should be a paragraph following the antithesis, i.e. your arguments disagreeing.  You should have a clear line of argument by now and have made a decision about whether you agree or disagree.  So now comes the synthesis, which explains your viewpoint clearly using examples from the text (although you should be using examples throughout).  You must be careful not to repeat anything in your conclusion, but you must now answer the question.  "How far do you agree...?"
