Author's Purpose and Tone — quick quiz

Read the passage and answer the question. "As the sun dipped below the horizon, the old lighthouse stood silent, its once-bright beam now dark. For decades, it had guided sailors safely to shore, a faithful guardian against the rocks. Now, replaced by modern technology, it waits—a relic of a time when human hands lit the lamps each evening. Perhaps one day it will shine again, not as a necessity, but as a symbol of our past." What is the tone of this passage?
