Final answer:
The descriptive statement is "A) The house has a blue roof", as it simply states a fact, while the other statements include subjective evaluations.
Step-by-step explanation:
The statement among the options given that is descriptive rather than evaluative is "A) The house has a blue roof". This sentence simply describes a characteristic of the house without ascribing any value or judgement to it. On the other hand, statements "B) The painting is impressive" and "C) The car is well-maintained" include evaluations based on the speaker's judgement or criteria, which go beyond mere description. Impressive and well-maintained are evaluative because they imply a standard of quality or care that isn't just fact-based description, but a viewpoint on what is considered good or desirable.
