Answer:
B. The scythe made a soft swishing sound.
Explanation:
Robert Frost's poem "Mowing" shows the speaker talking about work, the very simple nature of hard work. In this short one stanza poem, the speaker focuses on the act of mowing grass and how it became "the sweetest dream that labor knows."
Personification is the literary technique of giving human attributes or qualities to non-human or non-animated objects. And in his poem, Frost uses this technique to make the "scythe" talk, or rather "whisper". And in the act of whispering, the speaker seems to suggest that the scythe made a soft, swishing sound that seems to be like someone "whispering".
Thus, the correct answer is option B.
