The annual-leave example has a useful qualifier to carry into your evaluation set: the passage says eligible employees receive 20 days, while the question asks about employees generally. A fluent answer can quote the number correctly and still broaden who it applies to.

I would include a case where eligibility is unspecified and require the answer to retain that condition or ask for the missing detail. Pair it with a passage that explicitly defines the eligible group. That tests whether the generation step preserves the policy's scope, beyond finding a semantically similar paragraph and repeating its main number.
