Final answer:
The emphasized line is 'Strew on her roses, roses,' which has an iambic hexameter meter.
Step-by-step explanation:
The emphasized line in the given excerpt is:
Strew on her roses, roses,
This line has an iambic hexameter meter, which means it contains twelve syllables and six metrical feet. Each foot consists of one unstressed syllable followed by one stressed syllable.
In this line, the stressed syllables are emphasized, creating a rhythmic pattern that adds emphasis and drama to the words being spoken. The repetition of the word 'roses' further highlights it as the emphasized line.
