Student answer (Band 5.5)
The given chart illustrates the way how bio fuel called ethanol is produced from plants and trees.
From an overview analysis it manifest that all the mentioned process that are follow to make ethanol from plants and trees.
Going into depth, there are many steps which are follow to produce ethanol from plants and trees the first step is grow plant and trees they take sunlight+carbon dioxide+water to grow after this next step is harvesting the second step is pre-processing the next step is cellulose and after this the next step is processing by using chemicals next step is sugars the next and the last step is adding microbes after this ethanol is ready to use in transport like car, bus, truck etc and when whole the transport use ethanol as fuel there is no pollution the transport which use ethanol as a fuel they produce carbon dioxide in the place of pollution.

Task Achievement / Task Response — Band 5.5
The response covers the main stages of the ethanol production process, but it fails to present a clear overview or highlight the key features effectively. The description is overly simplistic and relies on a repetitive list-like structure (e.g., 'the next step is...'). While the process is outlined, the lack of a formal introduction and a cohesive summary of the main trends or stages limits the score. The explanation of the final stage regarding pollution is somewhat confused, as it does not clearly distinguish between the production process and the environmental impact mentioned in the diagram. To improve, focus on grouping related stages and using more precise terminology to describe the transformation of materials.
Coherence and Cohesion — Band 5.5
The essay lacks a clear paragraph structure, consisting of a very short introduction and one long, run-on paragraph. The use of cohesive devices is extremely limited and repetitive, relying almost exclusively on 'next step' or 'after this'. This makes the flow of the text mechanical and difficult to follow. There is no logical progression between ideas, and the lack of proper sentence boundaries (punctuation) further hinders coherence. To reach a higher band, you must use a variety of linking words (e.g., 'subsequently', 'following this', 'once the process is complete') and organize your information into distinct, logical paragraphs.
Lexical Resource — Band 5.5
The vocabulary is basic and repetitive, often relying on simple verbs like 'grow', 'make', and 'use'. There is little attempt to use academic or process-specific vocabulary (e.g., 'fermentation', 'distillation', 'raw materials'). Phrases like 'going into depth' are informal and not suitable for an Academic Task 1 report. Furthermore, there are errors in word choice, such as 'manifest' used incorrectly. To improve, you should learn and incorporate technical terms related to industrial processes and use a wider range of synonyms to describe the stages of production rather than repeating the same simple phrases throughout the text.
Grammatical Range and Accuracy — Band 5.5
The grammatical range is very limited, consisting mostly of simple, poorly constructed sentences. There is a significant lack of punctuation, with many sentences running into each other, which creates confusion. You frequently omit articles (e.g., 'the way how bio fuel' should be 'the way in which biofuel') and struggle with subject-verb agreement and verb forms (e.g., 'steps which are follow' should be 'steps which are followed'). There are no complex sentence structures attempted. To improve, focus on mastering basic sentence punctuation, using articles correctly, and practicing the passive voice, which is essential for describing industrial processes.
