PRODUCTION SCENARIO
Paralegals need a short summary of a long supplier agreement made only of sentences that appear verbatim in the document, with their positions, so every summary line can be traced to the source.

Answer: Extractive summarization
Extractive summarization produces a summary by extracting salient sentences from the source together with 'the start position and length of extracted sentences', so every line traces back. Abstractive summarization writes new sentences that are not verbatim extracts. Narrative and chapter title summarization are conversation summarization aspects: they segment and describe a dialogue, and neither returns source offsets.
