Task Achievement / Task Response: Band 5.0

The student attempts to summarise the diagram illustrating the production of ethanol, identifying the main stages such as plant growth, harvesting, pre-processing, cellulose extraction, and processing into sugars, followed by the addition of microbes and the creation of ethanol. The cyclic nature involving carbon dioxide release is also mentioned. However, the response fails to reach the minimum word count of 150 words, stopping at 139 words, which results in a penalty under Task Achievement. Additionally, some descriptions are vague or conversational, such as 'let disuss them un detail', and the overall overview of the process could be more clearly synthesised. To improve, the student must ensure the word count requirement is met and present the information with greater academic objectivity.

Coherence and Cohesion: Band 4.5

The text suffers significantly from a lack of proper paragraphing, appearing as a single dense block of text with run-on sentences. Cohesive devices are either missing or misused, relying heavily on informal spoken connectors like 'at first', 'at second stage', and 'coming up to fourth'. Logical progression is severely hindered by punctuation errors, such as missing full stops, commas used inappropriately, and fragmented clauses. There are attempts to link the stages sequentially, but the overall organisation is faulty, mechanical, and difficult to follow. Proper paragraph division separating the introduction, main processing stages, and the carbon dioxide cycle is essential for a higher band score.

Lexical Resource: Band 5.0

The student demonstrates a limited range of vocabulary with multiple spelling and word-choice errors. Examples include 'digram beneth' instead of diagram beneath, 'sverel' for several, 'un detail' for in detail, 'ethonal' for ethanol, and 'difrrent vehicels' for different vehicles. There is an attempt to use process-related terms from the prompt such as 'harvesting', 'pre-processing', 'cellulose', and 'microbes', but the frequent spelling mistakes ('grows' instead of grow, 'cut dowconverted' instead of cut down and converted, 'relesed' for released, 'carbondioxide' for carbon dioxide) impede readability and demonstrate a lack of control over basic academic vocabulary.

Grammatical Range and Accuracy: Band 4.5

The grammatical range is extremely restricted, consisting mainly of flawed simple and attempted complex sentences strung together without proper boundary punctuation. There are numerous grammatical errors throughout the text, including subject-verb agreement issues ('plants and trees grows'), missing prepositions, and incomplete clause structures ('the process of is here in the processing'). Punctuation is virtually non-existent between clauses, leading to severe run-on sentences like 'at third it moves pre-processing then for making cellulose , coming up to fourth and the main factor the process of is here...'. These frequent errors frequently strain the reader and reflect very poor control over basic sentence construction.
