Why does the old printed book seem strange to the children?

Correct answer: Because they are used to screen-based telebooks

The governing concept is that technology changes reading habits and perceptions of ordinary objects. Tommy discovers a printed book whose words remain fixed on paper, unlike the electronic telebooks familiar to the children. Because their everyday reading is screen-based and technologically changeable, the old paper format seems unusual and even wasteful to them. Option B is correct because it explains the children’s reaction through their technological upbringing. Option A is false because the printed book does contain words. Options C and D name unrelated elements: a mechanical teacher is a teaching machine, while a Geography sector is only one part of that machine, not a type of book.
