Ola wars continue:Coke and pepsi in 2010

This is a presentation paper. I have 2 questions that I need you to answer then I will present these questions base on what you answered exactly word by word. The questions are:
1. Describe the history of Coke and Pepsi.
2. Why, historically, has the soft drink industry been so profitable?
For the question 2, i have an article for you to read then answer this question base on this article only. And the question 1, you can just search the answer online. It would be great if you do the presentation in order (question 1 first then question 2). I hope that I can have it back on time. Thank you so much!!
