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 given diagram illustrates process of Biofuel production and how it is generated.

Overall, the process chart consists of abundance steps. It beginning with harvesting and it ending with transportation.

At the outset, plants grows in the field it reduced the carbon dioxide. first, crops are harvested by the tractor by the help of man. Further, before going to be transferred in the cellulose, the field are inserted in the pre-processing in and out method. After that, cellulose through it goes in to the chemical process. there is sugar and the microbes are added.

Following this, the Ethanol is divided into various categories. there are several vehicles which are produced carbon dioxide such as car, commercial truck and air plan. which are exhausted emission gases, and finally all harm full gases are absorbed by the large numbers of trees. subsequently, it gives fresh and cool air in the climate.

AI examiner evaluation

Task Achievement / Task Response — Band 5.0

The response fails to meet the minimum word count requirement of 150 words, which negatively impacts the score. While the student attempts to describe the process, the summary is incomplete and lacks a clear overview of the key stages. The description of the chemical process is vague, and the explanation of the carbon cycle is somewhat disconnected from the actual diagram provided. To improve, ensure all stages are clearly identified and described in a logical sequence, and provide a more comprehensive summary of the main features shown in the diagram.

Coherence and Cohesion — Band 5.5

The response is organized into paragraphs, but the logical flow is often interrupted by awkward phrasing and unclear transitions. While some cohesive devices like 'At the outset' and 'Following this' are used, they are sometimes applied incorrectly or do not effectively link the ideas. The referencing is occasionally confusing, such as in the sentence 'before going to be transferred in the cellulose', which makes the progression of the process difficult to follow. Improving the use of linking words and ensuring each paragraph has a clear, singular focus would enhance the overall coherence.

Lexical Resource — Band 5.0

The vocabulary is quite limited and repetitive. There are several instances of imprecise word choice, such as 'abundance steps' instead of 'numerous steps' or 'harm full' (spelled as two words). The student struggles to use technical terminology accurately, often relying on basic descriptions that do not demonstrate a wide range of vocabulary. To achieve a higher band, the student should focus on using more precise, topic-specific vocabulary related to industrial processes and environmental science, and pay closer attention to correct spelling and word formation.

Grammatical Range and Accuracy — Band 5.0

The response contains frequent grammatical errors that occasionally impede communication. There are issues with subject-verb agreement ('plants grows'), incorrect article usage, and awkward sentence structures ('the field are inserted in the pre-processing'). The range of sentence structures is limited, consisting mostly of simple or poorly constructed complex sentences. Punctuation is also inconsistent, with missing capital letters at the start of sentences. A focus on mastering basic sentence construction and proofreading for common errors like verb tense and agreement would significantly improve the quality of the writing.
