   A team is building a RAG system for a large book. The book has a continuous narrative with no headings or chapters. The target model has a context window of 2048 tokens. They are using a fixed-size chunking strategy with a chunk size of 1000 tokens and an overlap of 100 tokens. During evaluation, they find that the system fails to answer questions about events that span more than 1000 tokens. What is the most effective way to improve the system's performance?

   • AIncrease the overlap to 500 tokens
   • BSwitch to a recursive chunking strategy with a chunk size of 1000 tokens and an overlap of 100 tokens
   • CUse a semantic chunking strategy that groups sentences by embedding similarity
   • DDecrease the chunk size to 500 tokens and increase the overlap to 100 tokens

   A data engineer is preparing a technical manual for chunking. The manual contains chapters, sections, paragraphs, tables, and code blocks. Which initial step is most important for informing the chunking strategy?

   • AConvert the entire document into a single chunk to preserve all context.
   • BImmediately split the document into fixed-size chunks of 512 tokens to ensure uniformity.
   • CIdentify the hierarchical and semantic structure of the document, such as headings, paragraphs, tables, and code blocks.
   • DRemove all tables and code blocks to simplify the document before chunking.
