Task Achievement / Task Response: Band 5.0
The response attempts to describe the biofuel production process, but it falls short of the 150-word minimum, containing only 135 words, which incurs a penalty under Task Achievement. While the overview attempts to state the main stages, the summary is incomplete and trails off abruptly at the end ("...the releases some"). Key features such as the cyclical nature of carbon dioxide absorption and release are partially missed or awkwardly expressed. Consequently, the task is addressed only partially, warranting a Band 5.0.
Coherence and Cohesion: Band 5.0
The text exhibits some organizational structure through sequencing words like "Firstly", but the overall progression is disrupted by mechanical transitions and incomplete sentences. Paragraphing is not effectively utilized, as the entire response is clumped together into one block of text, aside from a brief opening sentence. Referencing and cohesive devices are sometimes inadequate or repetitive, leading to a disjointed flow that requires effort from the reader to follow.
Lexical Resource: Band 5.0
The vocabulary used is relatively basic and repetitive, with several awkward word choices and phrasing such as "making biofuel namely ethanol", "callled ethanol", and "the releases some". There are spelling errors such as "diveded", "sebsequently", and "proccessing". The student attempts some less common vocabulary like "cellulose" and "microbes", but the range remains limited and inadequate for a higher band, reflecting Band 5.0 performance.
Grammatical Range and Accuracy: Band 5.0
The grammatical range is limited, relying heavily on simple or awkwardly constructed complex sentences. There are frequent errors in tense consistency, subject-verb agreement, and prepositions, such as "where they absorbs", "When trees grew sebsequently, tractor will harvest", and "pass through from the chemical process". Furthermore, the text cuts off mid-sentence, leaving a dangling clause. These persistent errors cause some difficulty for the reader.
