Final answer:
The second and fourth stanzas both feature a series of unanswered questions. The last line often concludes the theme or emotional journey of a poem. The rhyme pattern and indentations contribute to the poem's rhythm and highlight thematic elements.
Step-by-step explanation:
The second stanza (lines 5-8) and the fourth stanza (lines 13-16) of the poem are similar in that they both consist entirely of unanswered questions. This technique contributes to the thematic exploration and adds to the reflective and questioning tone of the poem. Notably, in the revision process, the poet William Blake introduced significant changes like the introduction of 'the Lamb' as a dramatic contrast to the tiger and a reference to a creator figure in the published version.
The last line of the poem often provides a sense of resolution or finality. In some poems, it can tie together the themes and questions raised throughout the verses, leaving the reader with a poignant thought or image to reflect on. Lastly, the rhyme pattern contributes to the rhythm and structure of the poem, which can support and enhance the poem's themes and emotional impact.
Indentations in poetry, such as in the lines discussed, serve to draw attention to certain lines, possibly indicating a change in tone, pace, or thematic significance. Moreover, common poetic symbols like looms, rivers, and mirrors carry rich associative meanings both generally and within the specific context of the poem.
