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 5.0)
The illustration depicts how ethanol is produced from plants and trees.
Overall,the whole process begin with when plants absorb energy through sunlight then they grew and end with the produce of carbon dioxide through different vehicles then these can be used again through sunlight.
The process start with plants absorbing carbon dioxide through sun light and grew up. After that reaping the trees through tractor and then transported to the intial processing area, while they compressed into cellulose.Therefore, these are send to the main processing area which they can pass through the different reactions.
In main processing area, take some reaction on cellulose in the result sugars can be produced and then transform into microbes. Furthur these microbes changed into ethanol.Morever these are used into different vehicles and release carbon dioxide in the air.Furthur more these carbon dioxide mixed into air.At the end these can be useable for plants and trees.

Task Achievement / Task Response: Band 5.0
The response covers the main stages of the ethanol production cycle shown in the diagram, beginning with plants absorbing energy and concluding with carbon dioxide release. An overview is attempted in the second paragraph, outlining the cycle from plant growth to vehicle emissions. However, the explanation of certain steps is unclear and inaccurate; for instance, stating that plants are 'compressed into cellulose' and that sugars 'transform into microbes' misinterprets the sequential relationship of the process steps. Additionally, the role of carbon dioxide throughout the cycle is not fully articulated. Therefore, the response addresses the task only partially, corresponding to a Band 5.
Coherence and Cohesion: Band 5.0
The text is divided into four paragraphs, attempting an introduction, an overview, and body paragraphs detailing the process. However, the logical progression is frequently disrupted by awkward transitions and confusing cohesion (e.g., 'Furthur these microbes changed into ethanol. Morever these are used into different vehicles...'). Referencing is often unclear, with pronouns like 'these' and 'they' referring ambiguously to different nouns across sentences. Paragraphing is present, but internal cohesion is mechanical and inadequate at times, placing the response firmly at Band 5.
Lexical Resource: Band 5.0
The vocabulary used is basic and repetitive, relying heavily on simple terms from the prompt such as 'plants', 'trees', 'processing', 'sugars', and 'ethanol'. There are noticeable word choice errors and unnatural collocations, such as 'reaping the trees', 'intial processing area', and 'compressed into cellulose'. While the vocabulary is minimally adequate to convey a basic understanding of a cyclical process, the frequent errors and lack of less common lexical items prevent the response from reaching a higher band, reflecting a Band 5 level.
Grammatical Range and Accuracy: Band 5.0
The response exhibits a very limited range of grammatical structures, relying primarily on simple sentences with frequent attempts at complex clauses that are rendered faulty. There are persistent errors in tense usage ('begin with when', 'grow and end', 'start with plants absorbing... and grew up'), prepositions ('in the result', 'into the air'), and passive/active voice mechanics ('take some reaction on cellulose'). Punctuation and spacing errors (e.g., 'Overall,the whole') are also present. These frequent errors cause significant difficulty for the reader and typify Band 5 grammar.
