Read the excerpt from an original poem. Stanza 1: The tide clock on the fish-house wall was always wrong by three; it promised noon to water that had already left the quay. Stanza 2: The old men trusted it the most when fog concealed the pier; a false face, faithfully consulted, can make a habit clear. Stanza 3: At dusk, the tide came in again without apology; the clock, still wrong, kept telling time for those who chose the sea. What does stanza 2 primarily do with the excerpt's focus on the tide clock?
