Are there any examples of anecdotes, allusions, analogies, or irony in this book? I need help ASAP!!!

There are definitely examples of each of the four literary
terms you mentioned (anecdotes, allusions, analogies, and irony) in the novel
  Into the Wild.  Irony plays a powerful role in the story of
Christopher McCandless; his death in the Alaskan wilderness is incredibly ironic.
 McCandless worked and longed for so long to reach a place of solitude in the Alaskan
setting, yet his presence there resulted in his death.  That, in and of itself, is an
irony.  It appears that, prior to his death, McCandless recognized his innate need for
love, yet he had placed himself in a situation that would not allow him to act upon that
recognition.  It is also ironic that, had McCandless simply researched what would become
his surroundings in the wild and accepted information, he probably would have been aware
of a means by which he could have survived his ordeal.
