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 givend diagram illustrates he cyclical process of biofuel and ethaol is produced with plants

the over view of this cyclical process is growing plants with the help of sunlight and carbondioxide next harvesting with tractor and with the support of other process produced biofuel that mitigate the pollution.

the plants are rising with solar energy and rapidly and start harvesting when it is ready leave some time for dry morever pre processing in machines separate the cellolose next making sugar with these plant preparing in intruments

other hand produced ethanol by adding of microbes and the ethanol used in vehicales that compress in diagram it is diligant process catalyst for producing ethanol next this is used in car truck and airoplane in replaceent of petrol dissel in results they have less pollution amd clean environment thats all the information provided in given diagram and cyclical procedure of obtaining ethanol.

AI examiner evaluation

Task Achievement / Task Response: Band 6.0

You identify the diagram as a cyclical process and include several central stages: plant growth using sunlight and carbon dioxide, harvesting, pre-processing, sugar production, adding microbes, and using ethanol in transport. This gives the reader a relevant account of the main sequence. However, some details are unclear or not supported by the diagram, such as plants being harvested only when “ready” and being left to dry. The overview also claims the fuel “mitigate[s] the pollution” and creates a “clean environment”; the diagram shows carbon dioxide returning to the plants, but does not explicitly compare pollution levels or state this environmental outcome. To strengthen the response, describe the cellulose and processing stages more precisely and explain the carbon-dioxide cycle without adding conclusions not shown.

Coherence and Cohesion: Band 5.5

The response has a recognisable overall order, moving from plant growth through processing to ethanol use, and phrases such as “next” and “other hand” attempt to guide the reader. However, the ideas are crowded into a few long, loosely connected sentences, so the progression is not consistently clear. For example, “next making sugar with these plant preparing in intruments” does not clearly show how cellulose is processed into sugars, while “other hand produced ethanol” makes the transition difficult to follow. The opening overview and final summary also repeat similar information. Use separate paragraphs for the overview and stages, and connect each stage with clear, accurate sequencing language and references.

Lexical Resource: Band 5.0

You use some relevant process vocabulary, including “harvesting,” “pre processing,” “cellulose,” “microbes,” and “ethanol,” which helps convey the subject. There are also attempts at more specific language, such as “cyclical process” and “solar energy.” However, spelling errors and imprecise or unnatural word choices sometimes make the meaning difficult to understand: “ethaol,” “cellolose,” “instruments,” and “compress” are examples. Phrases such as “plants are rising” and “in replaceent of petrol dissel” are not natural descriptions of the stages shown. Build accuracy with standard process terms and check spelling; use “are grown,” “is converted into,” and “used as a fuel instead of” where appropriate.

Grammatical Range and Accuracy: Band 4.5

You attempt to combine stages and use some longer sentence forms, but control of sentence structure is inconsistent. Several clauses lack a clear subject or verb relationship, as in “next harvesting with tractor and with the support of other process produced biofuel,” and “other hand produced ethanol by adding of microbes.” Verb forms and agreement also need attention: “the plants are rising” does not fit the intended process description, and “the ethanol used” needs a finite verb such as “is used.” Missing articles and punctuation further obscure boundaries between ideas. Practise writing one complete sentence for each stage, using consistent present simple passive forms—for example, “The cellulose is processed into sugars”—and punctuate each sentence clearly.
