"Do you think you're ready for this class?" the yoga instructor asked.
 Bryant scoffed. "I was an athlete in high school. I could run a six-
 minute mile. I'm not exactly scared of your bend-your-right-leg-and-
 breathe nonsense."
 "O.K.," she said. "If you're sure. Some people are surprised by how hard
 it is."
 Ten minutes later, Bryant was a panting puddle of sweat on the floor. It
 was incredibly hard to keep up with the rest of the class. He had no
 balance, no flexibility, no ability to do any of the poses without getting
 wildly out of breath.
 "Now, class," the instructor said, looking straight at Bryant, "we're going
 to do tree pose, or, as some call it, the bend-your-right-leg-and-breathe
 nonsense."
 Which statement best explains how the plot of the story helps develop the
 main character?
