The first stanza of "Paul Revere's Ride" by Henry Wadsworth Longfellow primarily uses a rhythm pattern of five stressed syllables alternating with five unstressed syllables per line. This is characteristic of iambic pentameter, which typically consists of five iambs, where each iamb is made up of one unstressed syllable followed by a stressed syllable.
So, the correct response would be:
- five stressed syllables alternating with five unstressed syllables per line.
