Why is the discovery of the old book important in the age of technology?

It gives evidence of old paper-based education

The old book is important because it gives Margie and Tommy a glimpse of an earlier form of education. Its printed pages do not move like a telebook, and the words remain fixed on paper. This unfamiliar object leads the children to imagine schools in which pupils studied together with a human teacher. Thus, option A is correct: the book is evidence of paper-based, pre-mechanical learning. Option B is impossible because the book does not repair or upgrade the machine. Option C is also wrong because discovering the book does not physically send Margie anywhere. Option D reverses the contrast, since the object is an old printed book rather than a new telebook. The book therefore helps the story compare technological learning with traditional education.
