What imagery does Sandburg use in his poem "Fog"?

In the poem "Fog," Carl Sandburg employs vivid imagery to encapsulate the quiet and elusive nature of fog. The phrase “the fog comes on little cat feet” personifies fog as a stealthy and gentle presence, akin to the soft and silent steps of a cat. This imagery conveys the idea of fog creeping in quietly and subtly, which evokes a sense of calm and tranquility. The choice effectively captures the essence of the poem, showcasing how Sandburg's use of animal imagery conveys the stealth and gracefulness of fog as it envelops the landscape.

The other options present imagery that does not align with the central theme and tone of Sandburg’s poem. Clouds and thunder suggest a stormy or chaotic scene, while silent whispers of the night might imply a different kind of stillness not directly associated with fog. Waves crashing on shore evoke a sense of power and movement, contrasting sharply with the gentle arrival of the fog. Therefore, the correct answer encapsulates the distinct and thoughtful way Sandburg portrays fog, emphasizing its quiet and subtle beauty.
