Read this passage from Dragonwings by Laurence Yep.
"Very good." Father took the card and put it carefully away in his pocket. "Did you see that demon's face, Moon
Shadow? He was surprised when I fixed his carriage. Machines aren't all bad. Some of them may be the true
magic. We might not be able to speak too well with the demons, but in machines there's a language common to us
all. You don't have to worry about your accent when you're talking about numbers and diagrams."
I was getting excited. "Maybe the Dragon King was right. Maybe the magic takes a different form in our land.
Maybe that's why you don't need words for it."
Father wiped his hands on an old rag in the back of the wagon. Then he held up his hands. He had not been able
to get off all the oil, for the lines of his hands were still black.
"Well, you know, repairing the horseless carriage was a lot like healing the Dragon King. My hands just seemed to
know what to do."
In this passage, what revelation do the narrator and his father have about the setting?
that the Americans may not be demons after all
that magic is more important than modern machinery
that a common language is not always necessary for communication
