What does 'overlap' mean in the context of chunk boundaries?
Overlap means that some parts of text appear in more than one chunk to keep context between chunks.

What happens if there is no overlap between chunks?
Without overlap, the system might miss connections between chunks, causing loss of context and less accurate results.

What is the main reason to use overlap in chunking?
✗ Incorrect
Overlap keeps some text repeated in chunks so the system understands the flow better.
What is a chunk boundary?
✗ Incorrect
Chunk boundary is where one chunk stops and the next one starts.
If chunks have no overlap, what is a likely problem?
✗ Incorrect
No overlap can cause the system to miss connections between chunks.
Which is a good practice for chunk boundaries?
✗ Incorrect
Cutting at sentence ends keeps chunks clear and easier to understand.
What does chunk overlap usually contain?
✗ Incorrect
Overlap repeats some text from the previous chunk to keep context.
