The style and structure of Dickinson's poem most clearly reflect which development in American poetry during the late nineteenth century?

The correct choice highlights how Dickinson's poetry exemplifies the late nineteenth-century movement toward expressing abstract ideas through concrete imagery. In her work, Dickinson often transforms intangible concepts—like love, death, and identity—into vivid, sensory experiences. By employing specific, tangible images, she enables readers to grasp complex emotional states and philosophical reflections, making her writing both relatable and profound.

This approach marked a shift in American poetry, where poets increasingly moved away from merely ornamental language or abstract, vague expressions toward a more grounded depiction that utilized imagery to convey deeper meaning. Such a technique not only deepened the emotional resonance of her poems but also reflected the broader movement in modernist thought, ultimately influencing subsequent generations of poets who aimed to evoke abstract experiences through vivid, concrete detail.
