IELTS Writing Task 1 question
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 diagram represents the yield of ethanol a well-known biofuel used for many purpose.
Overall, maufacturing process contains severals stages, beginning from the growth of plants and trees and ending with transforting via plane, truck and small vehicles.
To begin, with the faciliation of resources such as sunlight + CO2 plants and tress are cultivated. After that, crops are loaded into a tractor to depart for harvesting. Once reaping is done, agriculture products passes through a pre-processing machine, which shattered them into pieces, these are later shaped as bunch of veins called cellulose which are brought into the lab for chemical processings, in addition to form sugars.
Subsequently tiny microbes are combined, as a result, ethanol fuel is generated. Ultimately, this is utilized into various modes of transpostation such as, Plane, Trucks and cars. Whenever they taken to movement, they releases carbondioxide into the air. Hence, the linear cycle continues its process repeatedly.

Task Achievement / Task Response: Band 5.5
The response addresses the main features of the ethanol production process diagram, but some parts are only partially covered and contain inaccuracies or under-developed ideas. For example, the student mentions that crops are 'loaded into a tractor to depart for harvesting', which misinterprets the sequential relationship between plants growing, harvesting, and pre-processing shown in the visual data. While an overview is attempted, it lacks precision regarding the cyclical nature of the carbon dioxide release and absorption. The information provided is somewhat limited, and key stages such as the chemical processing into sugars and the addition of microbes are glossed over with general statements rather than being fully reported and contrasted.
Coherence and Cohesion: Band 6.0
The response demonstrates a coherent overall arrangement with a clear attempt at paragraphing, separating the introduction, overview, and body steps. However, cohesion is sometimes faulty or mechanical, relying heavily on basic sequencing words like 'To begin', 'After that', and 'Subsequently'. Referencing is not always entirely clear, such as in the sentence 'these are later shaped as bunch of veins called cellulose', where the pronoun reference is slightly ambiguous and disrupts the logical flow. Paragraphing is present, but the logical progression within paragraphs stumbles due to awkward transitions between the physical actions and chemical stages of the diagram.
Lexical Resource: Band 5.0
The lexical resource is limited and minimally adequate for the task. The student attempts some less common vocabulary, such as 'cultivated', 'cellulose', and 'transportation', but these attempts are accompanied by noticeable errors in word choice, word form, and spelling, such as 'maufacturing', 'transforting', 'faciliation', and 'carbondioxide'. Collocations are occasionally unnatural, for instance, 'faciliation of resources' or 'taken to movement'. These lexical inaccuracies and spelling errors occasionally cause some difficulty for the reader, restricting the vocabulary score to a lower band.
Grammatical Range and Accuracy: Band 5.0
The response displays a limited range of grammatical structures, relying mostly on simple sentences alongside a few attempts at complex forms that are frequently faulty. There are noticeable errors in verb tenses, voice, and prepositions within grammatical patterns, such as 'agriculture products passes' (subject-verb agreement error), 'is utilized into various modes' (incorrect preposition), and 'they releases carbondioxide'. Punctuation errors, such as missing commas in introductory phrases and unnecessary commas before lists, also occur. These frequent errors in basic and attempted complex structures can cause occasional strain and difficulty for the reader.
