34. A summarization team measures ROUGE against reference summaries. A candidate receives a high score, but a reviewer finds an incorrect claim. Which conclusion is most appropriate?
35. A support team compares two applications: one assigns a ticket to a fixed category, and another drafts a new response tailored to the ticket. Which statement best distinguishes the second application?
36. A supported model repeatedly receives the same long instruction prefix followed by a different user question. The provider offers prompt caching for qualifying prefixes. Which statement best describes the potential benefit?
