There it was. Page after page of neat, black type. For sentence four: must have rained .
The real lesson wasn’t modals or past participles. It was this: an answer key gives you the what . But only your own struggle gives you the why . And the why is what stays with you long after the class ends.
Dr. Alvaro didn’t look angry. He looked disappointed. “The answer key is a map,” he said softly. “But you have to walk the road yourself. Go home. Don’t look at the key. Make ten wrong guesses. Then come see me.”
