Kate Chopin "The Story of an Hour" Q&A

In what ways is this passage significant? "She could see in the open square before her house the tops of trees that were all aquiver with the new spring life. The delicious breath of rain was in the air. In the street below a peddler was crying his wares. The notes of a distant song which some one was singing reached her faintly, and countless sparrows were twittering in the eaves." What kinds of sensory images does this passage contain, and what senses does it address? What does the vision through the open window mean to her? Where else does she taste, smell, or touch something intangible in the story?
