Greg can run and jump faster than anyone else, but he's always last in the race. He tried hard to listen in class but "all that he heard was a murmur, a fur of words, a blur of words." Then a new teacher comes to school and starts to observe him. To prove her theory about him, she takes the class outside for a race. When she says, "Go", he is last. When she uses her arm dropping as the signal for the start, he wins. ( )
