Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
Student answer (Band 5.0)
The diagram illustrates how a biofuel production called ethanol is produced in different steps from starting to ending of this process.
Overall, it is clear that, the process of making the ethanol is produced by 10 different process. While it begins from plants and tree grows to production of biofuel at the end.
At a beginning of this process different types of plant are grown in the one particular farming area. After some decade while it is ready it should be harvest and send them to the pre-processing location. In this process the material is finely cellulose then it would be taken onto the laboratory for the proper examination and for the ethanol processing. At first processing ethanol the major step is to prepare the sugar cell and add some microbes to create ethanol. After that the procedure is ready for distribution through the vehicles and other transportation. The biofuel production of ethanol which we can call it by carbon dioxide which it can use for various purpose of our life.

Task Achievement / Task Response — Band 5.0
The response attempts to summarise the diagram illustrating the production of ethanol, identifying several key stages such as growing plants, harvesting, pre-processing, laboratory examination, sugar cell preparation, and distribution. However, the overview is confused, stating the process consists of '10 different process' when the diagram shows a different flow, and there are inaccuracies in reporting the main features, such as mentioning carbon dioxide being used for various purposes which is not fully or accurately detailed in relation to the prompt. Ideas are sometimes under-developed or lack precise reference to the specific stages shown in the visual text. Therefore, the response aligns best with Band 5.0.
Coherence and Cohesion — Band 5.0
The text is organized into basic paragraphs, beginning with an introduction, an overview, and a body paragraph. However, overall progression lacks logical clarity and smooth transitions. Cohesive devices are used awkwardly or repetitively, such as 'At a beginning of this process' and 'After that the procedure is ready'. Referencing is sometimes unclear, particularly with pronouns like 'it' and 'they', which obscures the logical connection between steps. Paragraphing is attempted, but the internal structure of the main body paragraph is dense and difficult to follow. This performance is characteristic of Band 5.0.
Lexical Resource — Band 5.0
The vocabulary used is limited and repetitive, featuring frequent inappropriate word choices and collocations, such as 'biofuel production called ethanol is produced' and 'finely cellulose'. There are notable errors in word formation and phrasing that occasionally impede the reader's understanding, such as 'send them to the pre-processing location' and 'proper examination'. The range of vocabulary is minimally adequate to convey a basic topic-related message, but it lacks the precision and flexibility required for higher bands, placing it firmly at Band 5.0.
Grammatical Range and Accuracy — Band 5.0
The writer attempts a mix of simple and complex sentence forms, but attempts at complex structures are frequently faulty, leading to awkward phrasing and grammatical errors. Examples include 'After some decade while it is ready it should be harvest and send them' and 'biofuel production of ethanol which we can call it by carbon dioxide which it can use'. Errors in tense, subject-verb agreement, and prepositions are frequent and can cause some difficulty for the reader. While communication is not entirely broken down, the high density of structural errors limits the score to Band 5.0.
