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 6.0)

The diagram illustrates the production of sugar by seven different processes.

Overall, the diagram provides the information of each method used in the formation of sugar from sugar canes. This production consists of seven stages which are growing, harvesting, crushing, purifying juice, evaporator, centrifuge, and drying and cooling.

Initially, sugar canes are planted in the fields which take around 12 to 18 months to become mature. After sugar canes are grown up, they are harvested either by manually or by using a harvester machine. In the crushing process, sugar canes are squeezed by using a machine and their juice is collected. The juice is then purified by using a limestone filter in the purifying juice stage before sending it to the evaporator phase.

The purified juice is heated to make a syrup in the evaporator and a centrifugal separates the sugar crystals from the syrup in a centrifuge

Finally, it is dried and cooled in a container to obtain the sugar.

AI examiner evaluation

Task Achievement / Task Response — Band 6.0

The response covers all stages of the sugar production process, from growing to final cooling. The overview is clear, and the main features are highlighted. However, the description of the process is somewhat mechanical and lacks a cohesive flow between the stages. While the key steps are identified, the response could be improved by better linking the stages to show the progression of the material. For instance, the transition from the evaporator to the centrifuge is abrupt. Overall, the response addresses the requirements of the task well, providing a clear summary of the provided diagram.

Coherence and Cohesion — Band 6.0

The response is logically organized, following the chronological order of the process. Paragraphing is used, though the second paragraph is quite long and could have been split to improve readability. Cohesive devices such as 'Initially', 'After', and 'Finally' are used to guide the reader through the stages. However, some transitions are a bit repetitive or mechanical. The referencing is generally clear, but the flow between sentences could be improved by using a wider variety of linking words and phrases to connect the steps more fluidly.

Lexical Resource — Band 5.5

The vocabulary is generally appropriate for the task, with terms like 'centrifuge', 'evaporator', and 'purified' used correctly. There are some minor inaccuracies, such as 'grown up' (should be 'matured' or 'grown') and 'either by manually or by' (should be 'either manually or by'). The range of vocabulary is adequate for the task, but it lacks the sophistication and precision that would elevate it to a higher band. The use of technical terms is accurate, which is a strength in this type of task.

Grammatical Range and Accuracy — Band 5.5

The response uses a mix of simple and complex sentence structures. There are some grammatical errors, such as 'the diagram provides the information of each method' (should be 'information about') and 'a centrifugal separates' (should be 'a centrifuge'). The sentence 'After sugar canes are grown up, they are harvested either by manually or by using a harvester machine' contains redundant prepositions. Despite these errors, the meaning is always clear, and the errors do not impede communication. A wider range of complex structures would improve the score.
