Task Achievement / Task Response: Band 4.0

The response attempts to describe the process of recycling plastic bottles as shown in the diagram. However, the student struggles to accurately report the main features and stages of the process. While some steps are mentioned, such as sorting, compressing into blocks, crushing, washing, and producing pellets, the descriptions are heavily obscured by confusion and grammatical errors. For example, the student writes, 'working people have receive the bottle for wastage and deliver the recycling centre for sorting bottle.' Furthermore, there is no clear overall overview of the process. The interpretation of the visual data is incomplete and contains numerous inaccuracies regarding how the stages link together, leading to a band score of 4.0.

Coherence and Cohesion: Band 4.0

The text is divided into paragraphs, but the organization and progression are severely hindered by unclear referencing and inadequate cohesive devices. Transitional phrases are either misused or absent, such as 'In the summary,' and 'In the explanation,' which do not fit an academic process description. Pronoun referencing is frequently ambiguous, making it difficult to follow who or what is performing each action ('They forward the bottle... So, they create the producing and other products'). The logical flow from one step of the recycling process to the next is frequently broken by repetitive and confusing sentences, resulting in a band score of 4.0.

Lexical Resource: Band 4.0

The vocabulary used is very basic and repetitive. The student relies heavily on simple words and phrases, many of which are misused or non-standard in this context, such as 'wastage buckets,' 'bootle,' and 'water cane.' Attempts to use less common vocabulary fail due to poor word choice and collocation errors, such as 'high level machine' instead of 'heavy-duty machinery' or 'industrial crusher.' There are also noticeable spelling and morphological errors throughout the response ('storting,' 'compresssing'), which severely strain the reader and restrict the lexical score to a band 4.0.

Grammatical Range and Accuracy: Band 4.0

The grammatical range is very limited, consisting predominantly of simple sentences and flawed attempts at complex structures. There are persistent, highly intrusive grammatical errors throughout the text, including severe tense inconsistencies ('have receive,' 'is recycling'), incorrect subject-verb agreement ('many indivduals use,' 'The plastic bottles is recycling'), and missing articles or prepositions. These frequent errors distort meaning and make large portions of the text very difficult to understand, aligning the response with the descriptors for a band 4.0.
