What is the exposition of this story?i neeed help(: thanks.

In a piece of literature, the exposition serves to kind of
set the scene.  It is meant to give the reader the background to the story.  It gives
them information that they need to understand the rest of the story and it sets up the
conflict.

To me, the exposition of this story consists of
the first six paragraphs.  In this part of the story we learn that Jim and Della are
poor.  We learn that in some detail (how much he makes, how much she has left).  Then we
learn about the main conflict -- we learn that she wants to buy him a Christmas present
with that paltry amount of money.
