How sugar is produced from sugar cane

Student answer (Band 4.0)

This process of making sugar illsutrate different steps.Their is 12 to 18 months required for growing of sugarcane this is 1 step.Harvesting by different kinds of sugar cane before its crushing process.Their are two steps for cutting of sugar cane by machine and by hand work .Crushing is for their juice to start next step.After when juice is obtained limestone filter process lies on their to purify juice.Their is also a heat process in 5th step for making a syrup by evaporation.Eveporating process is before limestone filteration.Spertation of syrup and crystals which is on 6th step also second last step of this sugar making process. Centrifuge process convey seprated sugar which is generated by seperation sent into the last cooling and drying process on the 7th number. At last all seperated sugar is in the big round shape box where drying and cooling process. After these steps sugar is ready at last.

AI examiner evaluation

Task Achievement / Task Response — Band 4.0

The response attempts to outline the steps involved in the sugar manufacturing process, mentioning the 12 to 18 months of growing, harvesting, crushing, juice purification using limestone, heating and evaporation, separation of syrup and crystals, and final cooling and drying. However, the information is presented in a somewhat disjointed and confusing manner. For instance, the chronological ordering is muddled near the end, where the writer states that the 'Eveporating process is before limestone filteration,' which contradicts standard processing and the typical diagram flow. Furthermore, the selection of main features lacks clarity, and comparisons or overarching trends are absent. Consequently, the response falls into Band 4.0 as it touches upon the task only minimally and somewhat incoherently.

Coherence and Cohesion — Band 4.0

The organization of the text is weak, lacking proper paragraphing entirely as the entire response is written as a single block of text. There is no clear overall progression of ideas, and cohesive devices are either absent, repetitive, or inaccurate. Sentences are strung together using basic connectors like 'After when' and 'At last,' which creates a mechanical feel rather than a smooth flow. Referential pronouns such as 'their' are frequently misused in place of 'there,' leading to confusion in tracking the sequence of steps. Because information and ideas are not arranged in a coherent progression, the response aligns with Band 4.0 descriptors for this criterion.

Lexical Resource — Band 4.0

The vocabulary used is basic and repetitive, heavily relying on simple terms such as 'process,' 'sugar,' 'step,' and 'juice.' There are numerous word choice and lexical errors, such as 'spertation' instead of separation, and the incorrect use of 'box' to describe the final storage or processing container. Less common vocabulary items are attempted, such as 'evaporation' and 'centrifuge,' but they are often misspelled ('Eveporating') or incorrectly formed grammatically ('Spertation'). These errors and the limited range of vocabulary cause strain for the reader, placing the response firmly at Band 4.0.

Grammatical Range and Accuracy — Band 4.0

The grammatical range is very limited, consisting mainly of simple and attempted complex sentences that frequently break down. There are persistent basic grammatical errors throughout the text, including subject-verb agreement issues ('Their is 12 to 18 months required' and 'Their are two steps'), incorrect prepositions, and non-standard sentence structures. Punctuation is also poorly handled, with missing full stops and run-on phrasing. The frequency of these errors distorts meaning in places and impedes smooth communication, which is characteristic of the Band 4.0 descriptor level.
