Answer: A. Petit's reason for walking a wire between the two towers
Explanation: Philippe Petit is a man that became famous after walking on a high wire that was suspended between the tops of the Twin Towers. Both statements develop the idea of Petit's reason for walking a wire between the two towers since he claims that; "There is no why... life should be lived on the edge of life... you have to see every day as a true challenge, and then you are going to live your life on a tightrope." (Man on Wire, 2008).
