Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

One of the most interesting authors of the twentieth century, J.R.R Tolkien, achieved fame through his highly  inventive  trilogy,  The  Lord  of  the  Rings.  Born  in  1892,  Tolkien  received  his  education  from Oxford and then served in World War I. After the war, he became a professor of Anglo -Saxon and English language and literature at Oxford University.

Although published in  1965,  the  three  books that  comprise  the  Lord of  the  Rings  were  written in

intervals  from  1936  to  1949. This was mainly due to Tolkien's responsibilities as a professor and the outbreak of World War II. By the late 1960s, this fascinating trilogy had become a sociological phenomenon as young people intently studied the mythology and legends created by Tolkien.

The trilogy is remarkable not only for its highly developed account of historical fiction but also its

success as a  modern heroic epic. The  main plot describes the struggle  between good and evil kingdom as

they try to acquire a  magic ring that   has the power to rule the world. The novels, which are set in a time

called  Middle  Earth,  describe  a  detailed  fantasy  world.  Established  before  humans  populated  the  Earth,

Middle Earth was inhabited by good and evil creatures such as hobbits, elves, monsters, wizards, and some

humans.  The  characters  and  the  setting  of  Middle  Earth  were  modeled  after  mythological  stories  from

Greece and Northern Europe.

Although readers have  scrutinized  the texts for inner meaning and have tried to connect the trilogy with  Tolkien's real  life experiences  in England during World  War II, he denied the connection. He claims that the story began in his years as an undergraduate student and grew out of his desire to create mythology and legends about elves and their language.

Tolkien  was  a  masterful  fantasy  novelist  who used  his  extensive  knowledge of  folklore to  create a body of work that is still read and enjoyed throughout the world today.
