The response presents a clear overview and covers all four materials with largely supported estimates. However, the opening detail sentence confuses the recycling rate for cans with their share of all recycled waste. The 1997 paper–glass ranking and plastic’s later plateau would improve the selection of detail.
8.0Ideas progress logically from overview to detailed comparisons, with effective use of referencing and cohesive devices such as 'thereafter' and 'in contrast', though some linking is slightly mechanical.
7.0Vocabulary is varied and effective for describing trends, including “registered”, “threefold”, “surged” and “recovered slightly”. Some expressions could be more precise: “the most recycled material” can suggest quantity rather than rate, and “over 20%” would communicate the absolute change more clearly in percentage points.
8.0GRAGrammatical Range and Accuracy
A good range of structures is used, including participial and relative clauses, and grammatical accuracy is generally high. The wording “an increase to 12% in the recycling rate” is cumbersome rather than clearly ungrammatical; placing “the recycling rate for plastic” as the subject would make the sentence easier to process.
