Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Hierarchical chunking that preserves document structure
Why this is correct
Hierarchical chunking maintains the document's section and subsection organization, improving retrieval relevance.
- ✗
Fixed-size chunking with no overlap
Why it's wrong here
Fixed-size chunks ignore natural boundaries, potentially splitting context across chunks and reducing coherence.
- ✗
Semantic chunking based on sentence boundaries
Why it's wrong here
Semantic chunking keeps sentences together but does not capture higher-level hierarchical structure.
- ✗
Random chunking with varying sizes
Why it's wrong here
Random chunking destroys any meaningful structure and leads to poor retrieval quality.
