Final answer:
Both "Digging" and the haiku explore the topic of farming as the connecting theme, despite other differing literary devices or structures they may use.
Step-by-step explanation:
The question asks which statement best describes the similarities between an excerpt from "Digging" and a haiku. The correct answer is that both poems explore the topic of farming. While both poems may employ different literary devices, structures or sound devices such as alliteration or rhythm, the unifying theme for both is the subject of farming and agriculture. This explorative similarity connects the two poems beyond their physical form or stylistic elements. The use of literary devices such as alliteration does indeed create interesting sounds, but it might not necessarily be the connecting point between the two mentioned poems unless both specifically use alliteration to discuss farming.
