The diagram below shows how a biofuel called ethanol is produced.
Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
Student answer (Band 5.5)
The provided image illustrates the information about how a biofuel called ethanal is produced.
As an overview, a total of ten steps are invalued in the process. While, it bigns with llants and trees grow and ends with use of Enthanol in vehicles.
At the first glance, sunlight and carbon dioxide provide energy to llants and trees for growth. Afterwards, when llants completely grow than works harvested them. Later, transfer harvested plants to pre-processing machine to make cellulose.
Furthermore, the cellulose than processing with chemical-s. In next step, im abter chemical processing sugars takeplace and Microbes add
in it. Finally, ethanol is
producted and ready to use
in vehicals and vehicals
reta releases carbondioxide
which restart same process.

Task Achievement / Task Response — Band 5.5
The response fails to meet the minimum word count requirement of 150 words, which significantly impacts the ability to fully develop the description of the process. While the main stages are identified, the explanation is fragmented and lacks the necessary detail to provide a comprehensive summary. The overview is present but underdeveloped, and the description of the steps is overly simplistic. To improve, you must expand on the technical stages of the process, such as the specific chemical treatments or the conversion of cellulose, to ensure all parts of the task are addressed thoroughly.
Coherence and Cohesion — Band 6.0
The essay is organised into paragraphs, which is a positive step. However, the logical flow is hindered by the brevity of the sentences and the limited use of cohesive devices. While some linking words like 'Afterwards', 'Furthermore', and 'Finally' are used, they are sometimes applied mechanically or incorrectly (e.g., 'While, it bigns with...'). The referencing is occasionally unclear, making the progression of the process feel disjointed. To achieve a higher score, focus on using a wider variety of linking phrases to connect ideas more fluidly and ensure that each paragraph has a clear, unified focus.
Lexical Resource — Band 5.5
The vocabulary is quite limited and repetitive, with several spelling errors that distract the reader, such as 'ethanal' (ethanol), 'llants' (plants), 'bigns' (begins), and 'vehicals' (vehicles). The range of vocabulary is insufficient to describe a technical process with precision. You rely on basic verbs like 'make' and 'add' rather than more specific academic terminology appropriate for a process description. To improve, focus on learning topic-specific vocabulary related to industrial processes and proofread your work carefully to eliminate basic spelling mistakes.
Grammatical Range and Accuracy — Band 5.5
The response contains frequent grammatical errors that occasionally impede communication. There are issues with subject-verb agreement (e.g., 'than works harvested them'), incorrect word forms (e.g., 'producted'), and awkward sentence structures. The range of grammatical structures is very limited, consisting mostly of simple sentences. There is little evidence of complex sentence construction, which is necessary for higher band scores. To improve, focus on mastering basic sentence construction and subject-verb agreement before attempting more complex structures. Pay close attention to verb tenses and ensure they are used consistently throughout the description.
