Which one of the following is most influential to the substance of Hallowell's "The Dinning Table"?

I can't verify this one with certainty, so I'll be upfront about that and reason through it.

Analyzing the question

The question asks what is "most influential to the substance" of the poem. "Substance" means the content or subject matter: what the poem is actually about. So we are looking for the element that shapes or determines that content.

Explaining the concept

In poetry analysis, these terms mean different things:

• Structure is how the poem is organized (stanzas, line arrangement, rhyme scheme).
• Atmosphere is the mood or feeling that results from the content.
• Style is the manner of expression (diction, imagery, figures of speech).
• Setting is the place and situation in which the poem occurs. It supplies the context, the people, the objects, and the events that make up the content.

Working through the options

• Structure (A), atmosphere (B) and style (C) are all ways of presenting or reacting to the content. They are shaped by the substance rather than shaping it.
• Setting (D) is the dining table and the situation around it. In a poem titled "The Dinning Table", the setting is the very source of the subject matter. What is said, who is involved and what is observed all come from that setting.

So the setting is what drives the substance, while the others are largely products of it.

Note on the key

I could not recall the poem's text well enough to cross-check this independently.

Answer: D, the setting of the poem

Exam tip: In literature questions, ask whether an element is the source of the content (setting, theme, characters) or a way of presenting it (structure, style, tone). "Substance" points to the source, so look for the content-bearing option.
