I only used two sources in the creation of my presentation. My presentation was more of an opinion and experience based argument, and I was already very knowledgable about the benefits of having a bike because I have tried doing my job without one. I did use two websites, which I gave the links on my presentation which gave me factual evidence of the dangers of riding a bike, and another source that explained how bicycling helps people lose weight. Overall, the sources helped my argument, and also hurt it with the evidence about the dangers of riding bikes in San Francisco, but I had to examine the counterargument, so it was worth it.
