What is the exposition, complication, climax and resolution?Please help me.

EXPOSITION.  This is the
background information regarding the two characters and their previous relationship. We
find that Fortunato has in some way offended Montressor, who has decided that he must
seek retribution against
Fortunato.

COMPLICATION. 
Montressor must find a way to kill Fortunato, but without the possibility of being
caught by authorities. He decides to lure him into the Montressor family catacombs
located beneath his home. But how will he do this without arousing Fortunato's
suspicion?

CLIMAX.  Montressor
suddenly thrusts chains upon Fortunato and secures him to the floor in a far corner of
the catacombs. Montressor begins to wall Fortunato up--building a wall of bricks that
will leave his chained prisoner no chance of
escape.

RESOLUTION.  Many
decades later, the older Montressor relates his story, assuring the reader that
Fortunato's body has never been found and that his revenge is
complete.
