Final answer:
The rhyming passage at the end of stanzas in 'Sir Gawain and the Green Knight' features a bob and wheel structure with an ABABA rhyme pattern.
Step-by-step explanation:
The number of lines contained in the rhyming passage at the end of stanzas in Sir Gawain and the Green Knight typically consists of what is known as a bob and wheel, where each stanza ends with a short line (the bob), followed by four longer lines (the wheel). These lines rhyme in an ABABA pattern, with slight variations throughout the poem. The bob, usually two to three syllables, sets up the rhyming pattern for the subsequent wheel. The precise number and structure of these lines may vary depending on the particular stanza and the translation or edition of the text.
