Tommy and Margie's reaction to the old book shows which cultural effect of technological change?

Correct answer: Older reading objects become strange for the new generation

The governing concept is cultural change in the medium through which people read and preserve knowledge. Tommy and Margie are accustomed to telebooks displayed on a screen, so a printed book with pages seems unusual and even strange to them. Their reaction does not mean that reading has disappeared; rather, a familiar cultural object from an earlier period has become unfamiliar because technology has changed everyday habits. Option C is correct because it identifies this shift in material culture and reading practice. A and D are absurd extremes, while B wrongly suggests fear instead of curiosity and surprise. The scene shows that technological progress can alter what a generation considers normal.
