An answer block is a short passage, usually two or three sentences under a clear heading, that answers one question directly and makes sense on its own. It is the unit most likely to be lifted into an AI answer.

Assistants quote passages, not whole pages. A direct answer near the top of a section gives them something clean to take.
How to measure or use it
For each target question, check that the page has one block that answers it first and is accurate on its own.
