If you wanted to learn about the barriers that Dr. Guttmann faced in his role at Stoke Mandeville Hospital and how he challenged those barriers, which text would you use: "Mann on a Mission" from "History in Detail: Dr. Ludwig Guttmann" or "About the Paralympics: Paralympic History"? Explain your choice, and cite at least two pieces of evidence (one that shows a barrier that Dr. Guttmann faced and one that shows how he challenged those barriers) from that text to support your choice
