Answer: Keep all news articles because the RAG application needs to understand non-technological content to avoid answering questions about them.
The question asks which approach is NOT advisable for building a RAG application focused on technology-only questions. Option C suggests keeping all news articles (including irrelevant content like sports and entertainment) so the RAG application can 'understand' non-technological content to avoid answering questions about them. This is not advisable because: (1) It introduces noise that can degrade retrieval quality and increase the chance of retrieving irrelevant documents when answering technology questions; (2) It wastes computational resources processing and storing irrelevant content; (3) The community discussion with 100% consensus and upvotes supports that filtering irrelevant content is better, with the comment 'garbage in, garbage out' highlighting why keeping irrelevant articles is problematic. In contrast, options A (system prompt filtering), B (filtering in retrieval), and D (upstream filtering) are all valid approaches to handle irrelevant content in a focused RAG application.
