Read the poem by Ella Wheeler Wilcox and answer the question.

"A word is a gem, or a stone, or a song,
Or a flame, or a two-edged sword;
Or a rose in bloom, or a sweet perfume,
Or a drop of gall is a word.
You may choose your word like a connoisseur,
And polish it up with art,
But the word that sways, and stirs, and stays,
Is the word that comes from the heart.
You may work on your word a thousand weeks,
But it will not glow like one
That all unsought, leaps forth white hot,
When the fountains of feeling run."

B. It says all words are pretty like gems.
C. It tells us words are delicate like flowers.
D. It shows that all words are as sharp as a sword.
