Question

Don Juan is generally written in ten-syllable lines. What poetic device does this represent?

1. rhythm
2. rhyme
3. assonance
4. point of view

Answer 1

Rhythm is the only one that's applicable. Usually ten-syllable lines means the text is in iambic pentameter so it's 5 pairs of syllables, one stressed and one unstressed. This creates a heartbeat-like rhythm when reading aloud.
