Try this yourself
Remove the date from your source. Run the prompt again and check whether the model invents one. Add this example to your evaluation set.
Check your understanding
The expected date is "not provided". A fluent sentence is not evidence that the date exists in the source.
A mistake to avoid
A long prompt is not automatically better. Repeated, contradictory requirements make it harder to diagnose failures.
Before looking at the answer, write a short explanation and one example of your own. Finish by naming one limitation of the method. Use Mark as read when you are ready, or return to the previous lesson if a term is unclear.
