The response presents a clear overview of net group growth, the under-15 decline and adult dominance, with well-selected data and comparisons.

8.0Information is logically grouped by time period with effective cohesive devices and clear progression, though occasional phrasing such as 'that for adults' and 'witnessing a 4% decline' is slightly mechanical.
7.0Vocabulary is flexible and precise, with natural terms like 'museumgoers', 'constituting', 'shrunk', and 'all-time high', and only rare awkward collocations such as 'make up the most significant figure'.
8.0GRAGrammatical Range and Accuracy
A wide range of structures is used with strong control, including complex tense forms, participle clauses, and contrastive constructions, with only rare minor slips such as the missing 'of' in 'an all-time high 42,000'.
