The Toulmin model is a widely used method of structuring a debate argument and consists of six elements: claim, data, warrant, backing, qualifier, and rebuttal. For instance, if you are arguing that smoking should be banned in public places, your claim would be that smoking should be prohibited in such areas. The data to support this would be the health problems smoking causes for both smokers and non-smokers. The warrant would be the reasoning that links the data to the claim, which in this case is that public places are shared by everyone and everyone has the right to breathe clean air. To further strengthen this point, backing from the World Health Organization showing exposure to secondhand smoke increases the risk of lung cancer, heart disease, and respiratory infections can be included. A qualifier such as "unless there are designated areas with proper ventilation and signage" can also be added. Finally, you can anticipate and address any counter-arguments such as smoking being a personal choice by including a rebuttal.
