Multiple Choice

For each passage, choose the appropriate letter to identify the author's tone. The truth is, if you asked me to choose between winning the Tour de France and cancer, I would choose cancer.Odd as it sounds, I would rather have the title of cancer survivor than winner of the Tour, because of what it has done for me as a human being, a man, a husband, a son, and a father.In those first days after crossing the finish line in Paris, I was swept up in a wave of attention, and as I struggled to keep things in perspective, I asked myself why my victory had such a profound effect on people.Maybe it's because illness is universal-we've all been sick, no one is immune, and so my winning the Tour was a symbolic act, proof that you cannot only survive cancer, but thrive after it.Maybe, as my friend Phil Knight says, I am hope.
