When Scout says she wants to tell everyone at school about Atticus's shooting skills, Jem tells her to keep quiet about it because: a. he thinks maybe it just slipped his mind about old Tim Johnson.
b. he doesn't want Scout to get in another fight at school. She's in enough trouble already.
c. Atticus is not proud of his talent for shooting and if he was, he would have told them already.
d. he thinks killing a dog is nothing to brag about. Jem is embarrassed about Atticus.
