Given a lock-operation paragraph and the question “What time did the gate reopen?”, the system highlights a span already in the paragraph. What kind of QA is that?
Select an answer to reveal the explanation.
Short Explanation
The paragraph already says when the gate reopened. Extractive QA just highlights that span. Inventing a time that is not there is generative QA. Clustering docks or drawing a Triton mesh is not highlighting a span.
Full Explanation
Extractive QA returns a span that already exists in the context. Inventing a new sentence is generative QA. Clustering and serving topology are not that task.
