Final answer:
Without the specific lines from 'Snowbound', we can infer the mood through the poem's setting, imagery, and emotional responses they provoke.
Step-by-step explanation:
The mood in lines 157-174 of John Greenleaf Whittier's poem Snowbound is not explicitly stated in the provided reference material. However, when analyzing poetry, we typically find that the mood refers to the emotional atmosphere established within the passage. For instance, the excerpt from Wordsworth's poem indicates a mood of helplessness and melancholy as the man witnesses the loss of his flock, and by extension, feels his love for his children wane under the pressure of poverty. The selection from Neutral Tones by Thomas Hardy seems to evoke a somber and reflective mood through the use of desolate imagery and diction. Moreover, the mood may shift throughout the poem, as seen in the examples provided where descriptions of nature, from the purple hue of twilight to a night rapidly enveloped in gray, often signify changes in emotion and tone. Thus, without the exact lines from Snowbound, we can infer that the mood might be conveyed through the setting, choice of imagery, and the emotions that these literary elements elicit.
