- What evidence-access distinction separates closed-book QA from an open-book QA setting?
- Open-book systems are forbidden to read documents
- Closed-book systems must always be more accurate
- Closed-book uses model parameters without external lookup; open-book can use supplied or retrieved documents
- Open-book systems cannot include a language model
- How can retrieval-augmented generation support a QA answer?
- By guaranteeing every retrieved passage is correct
- By eliminating the need to interpret any passage
- By automatically proving every output claim true
- By providing retrieved passages as evidence for generation
- Which boundary scores can an extractive QA head produce when selecting an answer span?
- Only a translation score for French output
- Scores for possible answer-start and answer-end positions
- Only a grammatical noun-or-verb label
- Only the alphabetical rank of each word
- Kini ami ti eto QA ti a ṣe daradara nigbati aye ko ni idahun?
- O ṣẹda idahun ti o lewu lonakona

- How does generative QA differ from requiring an extractive source span?
- It produces answer text rather than requiring an exact span from the passage
- It is restricted to one yes-or-no label in every task
- It never outputs any words present in a source
- It must output only a highlighted passage boundary
- In SQuAD-style QA evaluation, what can token-overlap F1 provide that exact match alone does not?
- Proof that every claimed fact is true
- Partial credit for answer words overlapping a reference
- A guarantee that no answer was copied
- The measured power usage of a server
- Why evaluate a QA system on paraphrased questions that preserve the intended meaning?
- To guarantee that every new paraphrase has a different answer
- To remove all passage evidence from every evaluation
- To replace answer quality with filename length
- To test sensitivity to changes in question wording
