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 above diagram shows the biofuel production of how ethanol is made. There is extensive amount of carbon dioxide the trees takes in the sunlights energy and carbon dioxide and the trees are being harvested and sent to pre processing and then the result is cellulose which is then further sent into processing and as a result its becomes sugar and when these is microbes added it transforms into ethanol
which is used in cars, trucks and airplanes for travelling and these produce carbon dioxide which is again absorbed by the trees.
And this is how the bio fuel called ethanol is made and it shows the pre process and process of the production and what the fuel advantages are and how widely it is used and how everything is safe in this as the process is in a loop and nothing is being harmed while making of this fuel.

Task Achievement / Task Response — Band 5.0
The response attempts to describe the process, but it fails to provide a clear, objective summary of the main features. Instead of focusing on the technical stages of ethanol production, the response includes subjective commentary such as 'nothing is being harmed' and 'how everything is safe', which is not appropriate for an Academic Task 1 report. The description of the process is somewhat disjointed and lacks the precision required to explain a scientific diagram. Key stages like 'pre-processing' and 'processing' are mentioned, but the explanation of the transformation is overly simplistic and lacks the necessary detail to fully convey the information presented in the diagram.
Coherence and Cohesion — Band 5.0
The response is poorly structured. It consists of two very short, run-on paragraphs that lack clear logical progression. The use of cohesive devices is limited and repetitive, with 'and' being used excessively to link clauses, such as 'and the trees are being harvested and sent to pre processing and then the result is cellulose'. There is a lack of effective paragraphing to separate the stages of the process from the concluding summary. The flow of information is mechanical, making it difficult for the reader to follow the sequence of events clearly.
Lexical Resource — Band 5.0
The vocabulary is basic and repetitive. The student relies on simple terms like 'made', 'sent', and 'used', which do not demonstrate the range required for a higher band. There are instances of awkward phrasing, such as 'extensive amount of carbon dioxide the trees takes in', which is grammatically and lexically imprecise. The response lacks the technical terminology necessary to describe a production process effectively. While the meaning is generally conveyed, the lack of variety and precision in word choice limits the score.
Grammatical Range and Accuracy — Band 5.0
The response contains frequent grammatical errors that affect the clarity of the writing. There are issues with subject-verb agreement, such as 'trees takes in' and 'these is microbes added'. Punctuation is largely absent, leading to long, run-on sentences that lack proper structure. The range of grammatical structures is very limited, consisting mostly of simple sentences joined by 'and'. There is a lack of complex sentence structures, and the errors in basic grammar are persistent throughout the text.
