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 6.0)

The given diagram illustrate the process that how a bio fuel called Ethanol is being made. Firstly, it starts with harvesting the plants. the farmers first harvest the plants and then and put it in the processing machine and make it a cellulose, in this process the excessive carbon dioxide also released in the air. After that, the cellulose is being processed from a chemical reaction in the lab and sugar is extracted from it. afterwards some microbes are added in the extracted sugar, the we produced our main product "Ethanol" from this process. this Ethanol is being used in the vehicles and also in air planes for the best performance of their engines. when these vehicles released carbon dioxide in the air, this is carbon dioxide is again absorbed by plants. plants after getting the direct sunlight and carbon dioxide grow again. the the complete cycle is again repeated. in this way can easily produced Ethanol by harvesting the plants.

AI examiner evaluation

Task Achievement / Task Response — Band 6.0

The response covers the main stages of the ethanol production cycle, from harvesting to vehicle usage and plant regrowth. However, the report lacks a clear overview or summary of the process, which is essential for Task 1. The description is somewhat repetitive, particularly in the final section regarding the cycle. While the main features are identified, the response would benefit from a more formal structure, such as an introductory overview sentence that highlights the cyclical nature of the process. The information is generally accurate, but the lack of a clear summary prevents it from reaching a higher band.

Coherence and Cohesion — Band 6.0

The response is organised chronologically, which helps the reader follow the process. However, the paragraphing is non-existent; the entire response is a single block of text, which negatively impacts the presentation. While some cohesive devices are used (e.g., 'Firstly', 'After that', 'afterwards'), they are sometimes used mechanically or with grammatical errors (e.g., 'the we produced'). The flow of ideas is generally logical, but the lack of paragraphing and the repetitive nature of the final sentences make the progression feel somewhat disjointed. Improving the use of linking phrases and separating the introduction from the body would significantly improve the score.

Lexical Resource — Band 6.0

The vocabulary is adequate for the task but lacks variety and precision. There is some repetition of basic terms like 'plants', 'carbon dioxide', and 'process'. Some word choices are slightly unnatural, such as 'make it a cellulose' instead of 'convert it into cellulose' or 'the we produced' which is a clear error. While the student successfully uses technical terms like 'ethanol', 'cellulose', and 'microbes', the overall range is limited. To improve, the student should focus on using more precise verbs and avoiding repetitive phrasing by using synonyms or referring back to previous stages more effectively.

Grammatical Range and Accuracy — Band 5.5

The response contains a mix of simple and some attempted complex structures, but there are frequent grammatical errors throughout. Examples include subject-verb agreement issues ('diagram illustrate'), missing articles ('in the air'), and awkward phrasing ('the process that how a bio fuel... is being made'). Punctuation is also inconsistent, with several run-on sentences and missing capital letters at the start of sentences. While the meaning is generally clear, the high frequency of errors in basic grammar and sentence construction prevents the response from reaching a higher band. Focusing on sentence boundaries and basic subject-verb agreement would be beneficial.
