   Not answered. What two kinds of memory did the original RAG model combine?
2. 2
   Not answered. Which statements describe the original RAG design?
3. 3
   Not answered. A chunk splits a refund rule from its exception. What should you fix first?
4. 4
   Not answered. Why can whole-document chunks work poorly for clause-level questions?
5. 5
   Not answered. What can fixed-window chunk overlap change?
6. 6
   Not answered. Why are dual encoders useful for first-stage retrieval over a large corpus?
7. 7
   Not answered. For L2-normalized vectors, which score gives the same ranking as cosine similarity?
8. 8
   Not answered. Dense retrieval misses an exact error code. What should you add?
9. 9
   Not answered. What can go wrong with approximate nearest-neighbor search?
10. 10
    Not answered. Three of four relevant chunks appear in the top five results. What is recall@5?
11. 11
    Not answered. Why might increasing retrieval k from 5 to 50 make an answer worse?
12. 12
    Not answered. With a rank constant of 60, what RRF score do ranks 1 and 4 produce?
13. 13
    Not answered. Why can RRF combine BM25 and vector rankings without normalizing their raw scores?
14. 14
    Not answered. Where should an expensive query-passage reranker run?
15. 15

21. 21
    Not answered. Which parts of a RAG pipeline should be evaluated separately?
22. 22
