IELTS Writing Task 1 question

The diagram below shows the manufacturing process for making sugar from sugar cane.

Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

How sugar is produced from sugar cane

Student answer (Band 7.0)

The diagram illustrates the process of producing sugar from sugarcane outlining seven distinct stages from cultivation to the final product.

Overall, the process begins with the growth of harvesting of sugarcane, followed by extraction, purification and crystallization of the sugar. The entire procedure involves both mechanical and chemical processes.

Initially, sugarcane grown for 12 to 18 months, before being harvested either manually, using a machete, or mechanically with a harvester. The harvested sugarcane is then crushed to extract its juice. This juice undergoes a purification process by passing through a limestone filter which removes impurities.

Next, the purified juice is heated in an evaporator, where leftover water is removed, transforming the liquid into a concentrated syrup.. The syrup is then processed in a centrifuge, which separates, the sugar crystals from the liquid. Finally, the extracted sugar crystals undergo drying and cooling, resulting in the refined sugar that is ready for distribution

AI examiner evaluation

Task Achievement / Task Response — Band 7.0

The response successfully covers all stages of the sugar production process, from cultivation to final distribution. You have identified the main features, such as the harvesting methods, purification, and the mechanical separation of crystals. The overview is clear and provides a good summary of the process. To reach a higher band, ensure that you explicitly highlight the key comparisons or contrasts between the mechanical and manual methods mentioned in the diagram. Overall, the information is well-selected and accurately reported, meeting the requirements of the task effectively.

Coherence and Cohesion — Band 7.5

The response is logically organized, with a clear introduction, overview, and sequential body paragraphs that follow the stages of the process. You have used cohesive devices such as 'Initially', 'Next', and 'Finally' to guide the reader through the steps. Paragraphing is used appropriately to separate the different phases of production. The flow of information is smooth, and the progression is easy to follow. There are no significant issues with referencing or cohesion, making the text coherent throughout.

Lexical Resource — Band 7.0

You have used a good range of vocabulary appropriate for a process description, such as 'cultivation', 'extraction', 'purification', 'crystallization', and 'concentrated syrup'. The terminology is accurate and fits the context well. There are no spelling errors, and the word choices are precise. To improve, you could incorporate more sophisticated collocations or varied synonyms to describe the mechanical actions, though the current range is sufficient for a clear and professional report.

Grammatical Range and Accuracy — Band 7.0

The response demonstrates a good control of grammatical structures. You have used a mix of simple and complex sentences, such as the passive construction 'is heated in an evaporator, where leftover water is removed'. While there are a few minor punctuation slips, such as the unnecessary comma in 'separates, the sugar crystals', these do not impede communication. The majority of your sentences are error-free, and the use of the passive voice is highly appropriate for describing a manufacturing process.
