The story of Robinson Crusoe's adventures on an uninhabited island is no longer as popular as it once was, nor does it inspire modern versions in popular fiction. This change in the reading public's taste has occurred because it is no longer easy to believe that undiscovered, uninhabited islands still exist.

The author's reasoning about the decreased popularity of Robinson Crusoe-like adventures in popular fiction is based on which of the following assumptions?

(A) Readers of popular fiction no longer wish to exchange their current lives for lives freed from the demands made on them by other people.
(B) Readers of popular fiction prefer settings that they can readily accept as plausible contemporary settings.
(C) The most satisfying type of popular fiction is that which enables the reader to participate vicariously in another person's adventures.
(D) As a result of media coverage, more people are acquainted with foreign locales today than at any time in the past.
(E) Readers of popular fiction are found among people with diverse interests, with the result that no, single type of fiction appeals to all.
