Task Achievement / Task Response — Band 5.0

The response attempts to describe the process of ethanol production but fails to provide a clear, structured overview. While it mentions the main stages, the description is fragmented and lacks the necessary analytical approach required for an Academic Task 1. The summary of the cycle is confusing, and the explanation of the stages (e.g., 'things go for pre processing') is too vague to be considered a clear report of the information provided in the diagram. Key features are not highlighted effectively, and the response lacks a professional tone suitable for a data summary task.

Coherence and Cohesion — Band 5.0

The response is written as a single, long paragraph, which makes it difficult to follow. There is a lack of logical progression between the stages of the process. Cohesive devices are almost entirely absent, with the writer relying on repetitive 'and then' or 'it will' structures to link ideas. This creates a mechanical and disjointed flow. The lack of paragraphing and the absence of clear transition words significantly hinder the readability of the report.

Lexical Resource — Band 5.0

The vocabulary is quite limited and repetitive. The writer uses basic terms like 'things', 'gives', and 'formed' rather than precise, process-oriented language such as 'converted', 'transformed', or 'facilitated'. There are also issues with word choice and spelling, such as 'hervestors' (harvesters) and 'aeroplain' (aeroplane). The range is insufficient to convey the technical nature of the diagram accurately, and the phrasing is often awkward, which limits the clarity of the description.

Grammatical Range and Accuracy — Band 5.0

The response contains frequent grammatical errors, including run-on sentences, missing punctuation, and incorrect verb tenses. Many sentences are poorly constructed, such as 'the carbon dioxide which cars and buses exist it will give carbon dioxide to the trees'. There is a lack of complex sentence structures, and the reliance on simple, error-prone clauses makes the writing difficult to parse. Punctuation is largely ignored, which further complicates the reader's ability to follow the intended meaning.
