This dataset brings together multiple news reports or consecutive updates about the same breaking event. Its question-answer examples require linking information across texts, including times, actions, and changes in event status, and provide answers, reconstructed timelines, and supporting evidence. Samples also capture ambiguities, conflicting accounts, or unresolved details, making the collection useful for evidence-grounded multi-hop reasoning, reasoning-focused supervised fine-tuning, and evaluation of news event understanding.
