A poem is any work of art that exploits some of the musical characteristics of language, such as meter, rhythm, euphony, and rhyme. A novel, though it may be a work of art in language, does not usually exploit the musical characteristics of language. A symphony, though it may be a work of art that exploit the musical characteristics of sounds, rarely involves language. A limerick, though it may exploit some musical characteristics of language, is not, strictly speaking, art. The statements above, if true, most strongly support which one of the following? ['If a novel exploits meter and rhyme while standing as a work of art, then it is both a novel and a poem.', 'If a symphony does not exploit the musical characteristics of sound, then it is not a work of art.', 'An example of so-called blank verse, which does not rhyme, is not really a poem.', 'Limericks constitute a nonartistic type of poetry.']
