Eleven-year-old Angela was attacked by a rare   21  affecting her nerve system. She was unable to walk and her movement was    22  in other ways as well. The doctors did not hold much    23   of her ever recovering from this illness. They    24 she'd spend the rest of her life in a wheelchair.They said that few, if any, were able to come back to    25 after suffering from this disease .The little girl was   26 . There, lying in her hospital bed, she would swear that she was   27  going to be walking again one day.
She was moved to a specialized    28 hospital in the San Francisco Bay area. All   29 that could be applied to her case were used. The doctors were moved by her undefeatable spirit. They taught her about imaging about seeing herself walking. If it would do   30 else, it would at least give her hope and something   31 to do in the long waking hours in her bed. Angela would work as hard as possible in physical treatments, and in exercise sessions. But she worked just as hard lying there faithfully doing her   32  , visualizing herself moving, moving, moving!
One day, 33 she was attempting, with all her might, to imagine her legs moving again, it seemed as though something 34  happened: the bed moved! It began to move around the room! She    35 out, "Look what I'm doing! Look! Look! I can do it”. I moved! I moved!"
Of course, at this very moment everyone else in the hospital was screaming, too, and running to a   36 place. People were screaming, equipment was  37 and glass was breaking. You see, it was the terrible San Francisco earthquake. 38 don't tell that to Angela. She    39  that she did it.
And now only a few years later, she's back in school, on her own   40  . No crutches, no wheelchair. You see, anyone who can shake the earth between San Francisco and Oakland can defeat a little disease, can't they?
