For outside evidence, can you create an entirely new line of reasoning? For example, let’s say you are talking about to what extent the columbian exchange affected the demographic of Africa, and nowhere in the documents does it talk about how it caused more females than males in some regions. Can we make a whole new paragraph and just talk about that piece of outside evidence in that paragraph?
Yes, as long as the new line of reasoning directly supports your argument. Be careful though…you have 45 minutes. You don’t get style points for being clever. The more concise and direct you can be with clear support of your argument, the better.
This would be a great way to show outside evidence because you would go into great detail about it. However, make sure you don’t spend so much time on the outside evidence that it takes away from your document evidence. Adding a separate paragraph may take up a lot of your time.
