Consider the data and reach your own conclusion as you develop your case. If you are contemplating a variety of viewpoints, attempt to categorize them under distinct sections. Examine the strengths and limitations of the various types of evidence and present them clearly and critically. Consider how previous cases have been resolved and present information about these earlier decisions. These are just some of the ways in which you can develop your argument. As you can see, it is not enough to simply state an opinion; you must also explain why you believe what you do. In doing so, you will be able to influence others by demonstrating that there are valid reasons for believing what you do.
