Read the passage carefully and choose the best answer to each question.

The history of communications is a chronicle of prophecies as well as of inventions. The appearance of each new medium has provoked the pronouncement that its predecessor is now obsolete. Yet such forebodings have seldom proved accurate. Television has failed to bury radio, for example, and email has not yet replaced letters or fax. Such a historical perspective should make us wary of the prediction that computers will soon replace the book. Whole libraries may be available on a single CD-ROM, but there remains the deep seated sensory pleasure of taking down a volume from the shelves or spreading out on a beach blanket with a page-turner.
