The illustration summarises the different steps of producing sugar from sugar cane - starting from growing sugar cane and the final product, which is sugar.

Overall, sugar cane plants for manufacturing sugar when they are a year to a year and a half old, and the sugar manufacturing process involves harvesting, crushing, making syrup, centrifuging, and finally drying and cooling.

As the diagram depicts, sugar cane plants are harvested from the fields when they are between twelve and eighteen months old. They are harvested either manually by human labourers or by using machines. In the third step, these sugar cane stems are crushed in a crusher machine to produce juice. Afterwards, the is purified by a limestone filter before the juice is heated by an evaporator to produce syrup. separated from syrup in a device called a centrifuge. The final step involves drying and cooling the produced sugar crystals to make the sugar that we consume.

Overall assessment

Why this response received Band 7.5

The response is a strong, accurate summary of the process: it covers all seven stages in the correct sequence with reliable data (12-18 months, manual or machine harvesting) and a clear overview. The main limitation is slightly mechanical sequencing and a few minor grammatical slips rather than any content weakness.

8.0

The response progresses logically through the process with effective paragraphing and consistent cohesive devices, though the sequencing relies somewhat on predictable stage-by-stage linking.

Lexical Resource

7.0

Topic-specific vocabulary is used flexibly and accurately (crusher, limestone filter, evaporator, centrifuge, syrup, crystals), with only minor imprecision such as 'sugar crystal' for the plural.

Grammatical Range and Accuracy

7.0

A range of structures including passives, relative clauses, and 'either...or' is used with good control, marred only by occasional slips like the subject-verb error in 'Sugar crystal is separated'.
