Hello, thank you for the question. Concerning maintaining a good strong argument throughout your essay, it's always good to keep using the question throughout. For example, starting your paragraphs (main points) by using some of the wording of the question can be useful in keeping a tight line of argument. Other points can come in the form of linking your conclusion for each main point back to the question, for example, 'therefore, idea X links to the 'wording of the question'and this is through.... Thank you!
