dialogue: George: Look, George, There's the Great Wall.
  Mose: I see. It's on top of the hills.
  George: Yeah, it stretches over for thousands of miles.
  Mose: I know. It's a major symbol of China.
  George: Where can we climb it?
  Mose: Do we have any choices?
  George: Well, we could take the cable car.
  Mose: Ah. . . let's just climb. It's more fun, I think.
  George: Okay. Let's go.
  Mose: Well, that was tough.
  George: But we made it.
  Mose: This looks great. When was it built?
  George: It was first built about twenty-five hundred years ago.
  Mose: That's remarkable.
  George: There are so many ancient relics in China.
summary: George suggests climbing the Great Wall instead of taking the cable car. They reach the top and admire the long history of the Great Wall.
