When writing a strong argumentative answer, it is very important to read the question properly, so that you understand exactly what you are arguing for!
The introduction lays the foundation for your answer; make sure to acknowledge both sides of the argument here, but then clearly state which line of argument you will be taking. If you can show in the introduction why this is clearly the correct decision. For example, “It is clear that ______ is a valid point, however, it can be argued to a lesser degree that ________”.
Your essay must address both sides of the argument, but I would put your line of argument first. Write concise and well structured paragraphs to really try and get your argument across. A good way of doing this is to use the PEA or PEE structure (Point, Evidence, Analysis or Point, Evidence, Explanation), because then you know that you are ticking all the ‘correct’ boxes. Remember to link the paragraph back to the question at the end, this reflects that you know what you are talking about, and gives an element of continuity to your writing, as well as a clear structure.
Move onto your ‘opposing’ argument, and follow the same pattern, but remember to reiterate at the end of the paragraph why the line of argument you are SUPPORTING is actually still the stronger argument.
Conclude by reiterating your line of argument in a summative and concise pattern, it is pivotal you link back to the question – and it is just as important to give a judgement. This means to give YOUR opinion, this makes your work stand out from the rest!
