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 8.0)

The diagram elucidates the multifaceted manufacturing process of sugar derived from sugar cane, encompassing seven distinct stages, from cultivation to the final product.

Overall, the process initiates with the growth of sugar canes over a duration of 12 to 18 months and culminates in the drying and cooling of sugar crystals, which ultimately yields raw sugar.

Initially, sugar canes are cultivated, a phase that typically spans 12 to 18 months. Upon maturation, the canes are harvested through mechanised or manual methods. They are then dispatched to a milling facility where the crushing process occurs, facilitating the extraction of the juice. Subsequently, this juice undergoes purification via a limestone filter, effectively eliminating impurities to produce a clean liquid ready for further processing.

Once purified, the juice is evaporated in a controlled environment to attain a syrupy consistency. This syrup is then subjected to centrifugation, a rapid spinning process that separates the sugar crystals from any residual liquid. In the concluding phase of the process, the extracted sugar crystals are dried and cooled, culminating in the production of raw sugar that is ready for refinement and consumption.

AI examiner evaluation

Task Achievement / Task Response: Band 8.5

The response fully and accurately addresses all parts of the visual prompt. The student covers all seven stages of the sugar manufacturing process, starting from the 12 to 18 months of cultivation and harvesting, through crushing, purification, evaporation, and centrifugation, down to the final drying and cooling. An effective and concise overview is provided in the second paragraph, capturing the starting and ending points of the process. All key features, including the two harvesting methods (mechanised and manual) and the use of the limestone filter and evaporator, are correctly identified and logically reported without any irrelevant details.

Coherence and Cohesion: Band 8.0

The response is exceptionally well-organised, with a clear logical progression from the beginning to the end of the manufacturing process. Paragraphing is used logically and effectively, separating the introduction, the overall trend, the initial stages, and the final production steps. Cohesive devices such as 'Initially', 'Upon maturation', 'Subsequently', and 'Once purified' are used naturally and flexibly to guide the reader smoothly through the sequential data without any mechanical over-use or awkward referencing.

Lexical Resource: Band 7.5

The candidate demonstrates a wide, fluent, and flexible range of vocabulary appropriate for an Academic Task 1 process diagram. Items such as 'elucidates', 'multifaceted', 'cultivation', 'mechanised or manual methods', 'syrupy consistency', and 'centrifugation' are employed with high precision. Collocations are natural throughout, and there are no noticeable lexical errors or inappropriate word choices, reflecting sophisticated control.

Grammatical Range and Accuracy: Band 8.5

The response exhibits a wide range of complex sentence structures used with full flexibility and high accuracy. Grammatical structures, such as participial phrases ('culminating in the production of raw sugar') and subordinate clauses ('Once purified, the juice is evaporated...'), are handled with excellent control. Punctuation is accurate, and the majority of sentences are completely error-free, representing top-tier grammatical performance.
