Read the excerpt from "The Discovery of Oz, the Terrible." "I thought Oz was a great Head," said Dorothy. . . . "No. . ." said the little man meekly. "I have been making believe." "Making believe!" cried Dorothy. "Are you not a Great Wizard?" "Hush, my dear," he said. "Don't speak so loud, or you will be overheard--and I should be ruined. I'm supposed to be a Great Wizard." "And aren't you?" she asked. "Not a bit of it, my dear; I'm just a common man." "You're more than that," said the Scarecrow, in a [sad] tone; "you're a humbug." "Exactly so!" declared the little man, rubbing his hands together as if it pleased him. "I am a humbug." "But this is terrible," said the Tin Woodman. . . . What theme does the excerpt support? It is wrong to trick people. Home is where the heart is. Love will always conquer all. Helping others brings rewards.
