The paired passages make a changed estimate and its stated basis inspectable. They also demonstrate why the revision link matters: the main paragraph can convey a different temporal scale if read alone.
The later layer changes the question instead of merely adding another fact. Its unresolved close preserves the gap between having new observations and having an adequate explanation for them.
The correction has a precise target. Keeping the poem and naming what changed lets the reader separate a literary work’s original occasion from the state of knowledge the collecting author now reports.
The old sentence remains visible beside the new interpretation and its stated grounds. This gives the revision a specific scope: what powers the author had underestimated. The reader can inspect that change while separately assessing whether his examples support the larger political account.
Reviewed examples have a source-linked editorial interpretation. Detected candidates are exact passages or structures retrieved by an explicit rule and still need interpretation. Neither label establishes a cause of bestseller longevity. No missing text is counted as a negative example.
