Question

identify the irregularity in the line. the line has no regular pattern of stress. the line has eleven syllables. the line uses an internal rhyme scheme.

Explanation:

In poetry, an irregularity can refer to a lack of a regular stress - pattern. Having a specific number of syllables (eleven in this case) isn't necessarily an irregularity. Using an internal rhyme scheme is a feature, not an irregularity. A lack of a regular stress pattern disrupts the normal rhythm of a line in poetry.

Answer:

The line has no regular pattern of stress.
