When they took him to the hospital, the doctor said he wouldn’t be able to play for six months. Steve went    22  him to and brought him books on basketball. At first Tom wasn’t going to read them. Then he began to read them and 23 that there were ways he could play basketball better. He began to think that books weren’t    24  .
