Denis stood up, his heart pounding. He looked at his notebook, but as he started to read, he realized he didn't actually know how to pronounce half the words he had copied.

Denis froze. He hadn't actually read the story; he had only copied it. "Um... some... big birds?" he guessed.

Slowly, the "puzzle" of the Derevyanko textbook started to come together. By the end of the term, Denis didn't need the "map" as much anymore—he was finally learning how to drive.

The next day in class, his teacher, Ms. Petrova, called him to the front. "Denis, your homework was excellent. Truly impressive. Would you mind reading it aloud for the class?"

Denis felt a bit ashamed. That evening, instead of just copying the answers, he used the GDZ to check his work after he tried it himself. He looked up the words he didn't know and practiced saying them out loud.

Ms. Petrova smiled kindly but saw right through him. "Denis, it's a lovely story. Tell me, what did you see at the top of the mountains?"
