The following Literary Excerpt was created by which of the following writers?"Every year, in the autumn, I became completely devoted to the chrysanthemum. I loved to arrange the cut flowers in vases but did not like the potted plants. Not that I did not think the potted plants beautiful, but our house having no garden, it was impossible for me to grow the plants myself, and those for sale at the market were overgrown and untrained; not at all what I would have chosen. One day, as I was sweeping my ancestral graves in the hills, I found some very unusual stones with interesting streaks and lines running through them. I talked to Yuen about them when I went home."Shen FuJohn KeatsWilliam BlakeHegel
