Answer Key and Explanations
Check these only after attempting every question.
1. B - converts a clear failure into silently mangled text
It succeeds on every input, which is what makes it dangerous.
2. B - sentence boundaries
A chunk retrieved alone has to make sense alone, which is stronger than merely fitting.
3. B - parses fine and needs a schema bound to catch
It becomes a row that will be reconciled against something real, and surfaces weeks later.
4. B - the qualifiers that bound it
The shorter summary reads better precisely because qualifiers are what make prose feel cluttered.
5. B - whether the cited chunk contains the claim
Presence is trivially satisfied by attaching an id to everything.
Practical Check
Apply this module to your own work: complete the module activity for *File Input, Summarisation and Extraction Workflows*, then write one sentence naming what your result shows and one naming what it does not.
Strong Answer Pattern
A strong answer names the task, the evidence used, the check performed, and the remaining limitation. It avoids "proved", "guaranteed", or "always" unless the evidence genuinely supports it.
