Thes blocks are passing through a crushing machine, these machine can crush the large block into tiny pieces, the pieces can goes into a large tub for washing process.

After collecting those washed plastic pellets, the pellets pour on the powder machine, the machine carfully powered the plastic pellets into raw materials. The raw materils comes out of a little bit moister, so they heated in a sun light surface. By using these raw plastic powerd to make a raw materials.

Task Achievement / Task Response: Band 5.5

The response attempts to cover all parts of the diagram, providing an overview and mentioning most of the stages involved in recycling plastic bottles. However, some ideas are limited and under-developed, and the information is not always accurately reported. For instance, the transition from waste collection to sorting is somewhat confused, and the explanation of stages like heating and creating raw materials becomes imprecise ('raw materials comes out of a little bit moister, so they heated in a sun light surface'). While the overall sequence is acknowledged, the lack of precision in describing the technical steps keeps the task achievement at a partial level.

Coherence and Cohesion: Band 5.5

The response shows some organization, using paragraphs to separate the introduction, overall statement, and body steps, and employs basic cohesive devices such as 'Initially' and 'After'. However, there is a lack of clear overall progression, and the flow between sentences is frequently disrupted by mechanical or inaccurate referencing. For example, sentences often run into one another with comma splices or confusing pronoun links ('these blocks are passing through a crushing machine, these machine can crush...'). The transitions between the sorting, washing, and pelletizing stages feel abrupt and repetitive, which prevents the essay from achieving a smooth and logical progression.

Lexical Resource: Band 5.0

The lexical range is limited and minimally adequate for the task. The student attempts some less common vocabulary related to the process, such as 'recycling center', 'compressed into blocks', and 'crushing machine', but these are accompanied by noticeable errors in word choice, form, and spelling (e.g., 'un-used', 'producting', 'grabage', 'meterials', 'moister', 'powerd', 'repeded'). These lexical inaccuracies and spelling slips cause some difficulty for the reader and reflect a restricted vocabulary control, preventing the response from reaching a higher band.

Grammatical Range and Accuracy: Band 4.5

The response demonstrates a very limited range of structures, relying primarily on simple sentences and basic clauses. Attempts at more complex sentences are frequently faulty, characterized by persistent grammatical errors such as severe subject-verb agreement issues ('there are 9 stages are involved', 'the workers should done by sorting'), incorrect verb forms ('should goes', 'are repeded'), and run-on sentences joined by commas instead of proper conjunctions or full stops. These frequent errors in grammar and punctuation cause considerable difficulty for the reader throughout the text.
