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 5.5)
The map shows the process of production of ethanol ( A biofuel) in various stages from raw material of nature to a final product as gas for vehicles.
Initially, farmers grow plants and trees. When the plants and trees are grown successfully, they are harvested and pre-processed for cellulose. Furthermore, Cellulose is processed and converted to sugar, in which microbes are added to form ethanol as an end product.
When the ethanol is obtained, it is transported to vehicles as a biofuel. This biofuel is used for many modes of transport, such as cars, trucks and aeroplanes. However, they cause emissions of carbon dioxide gas from the use of ethanol in vehicles. Conversely, Carbon dioxide gas is mixed with the air and harms the environment. However, it is reabsorbed by the plants as food for themselves. Thus, this process is more effective for the production of novel generation of biofuel.
In conclusion, The whole process benefits the nature without harming the society and wildlife santuaries that occured due to use of chemically produced fuels and their emission of gases, pollute the environment.Thus, Biofuel such as ethanol provide the better life to vehicle with low emission of these gases,it is produced from all plant based resources. Hence, not pollute the surrounding and nature.

Task Achievement / Task Response: Band 5.5
The response addresses the main parts of the diagram, but some stages are under-developed or inaccurately described. While the writer outlines the general flow from growing plants to processing cellulose, sugar, and ethanol, the description becomes overly generalized and shifts into personal opinions rather than summarizing the visual data. For instance, the conclusion spends considerable space discussing the broader societal benefits and wildlife sanctuaries, which are not depicted in the diagram. To reach a higher level, the writer should focus strictly on reporting the key features and cyclical nature of the process without introducing outside assumptions.
Coherence and Cohesion: Band 6.0
The response has a coherent overall arrangement and attempts to sequence the stages logically using transition words like 'Initially', 'Furthermore', and 'Consequently'. However, paragraphing and referencing are sometimes faulty. The transition between steps in the middle and the carbon dioxide cycle is somewhat mechanical, and referencing phrases like 'Conversely, Carbon dioxide gas is mixed with the air' lacks clear logical connection to the preceding point. To improve cohesion, the writer should ensure that cohesive devices are used more naturally to connect the cyclical stages of the diagram without abrupt shifts in focus.
Lexical Resource: Band 5.5
The writer uses an adequate vocabulary range for the task, attempting less common terms such as 'pre-processed', 'cellulose', and 'emissions'. However, there are noticeable lexical errors and awkward word choices, such as referring to ethanol as 'gas for vehicles' and mentioning 'wildlife santuaries' (spelling error). Collocations are occasionally unnatural, such as 'provide the better life to vehicle'. These errors do not completely impede communication, but they restrict the response. Expanding vocabulary precision and ensuring correct word forms and spelling will help lift the lexical score.
Grammatical Range and Accuracy: Band 5.5
The response demonstrates a mix of simple and complex sentence forms, but control over grammar and punctuation is inconsistent. There are frequent errors in articles, prepositions, and punctuation, such as 'the process of production of ethanol ( A biofuel)', 'Convert to sugar, in which microbes are added', and missing commas or incorrect capitalization ('In conclusion, The whole process...'). Complex structures are attempted, but they often contain minor grammatical slips. To achieve a higher band, the writer needs to produce a greater proportion of error-free sentences and improve control over article usage and punctuation.
