How did technology affect the habit of reading books in the story?

Correct answer: Children started reading screens instead of paper

Technology changed the physical form through which children read. In the future shown in the story, books are telebooks, and the words appear on a screen rather than on bound paper pages. Thus, option A is correct: children read screens instead of traditional paper books. Option B is too extreme, because reading continues; only the medium has changed. Options C and D are absurd alternatives and have no connection with the events or ideas of the chapter. This detail helps establish the technologically advanced setting in which Margie and Tommy live. It also creates a contrast between their screen-based telebooks and the printed book about old schools that Tommy finds. The contrast makes Margie curious about an earlier form of education and reading, showing that technology changes habits without necessarily eliminating the desire to learn.
