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 provided flow chart illustrates the systematic, multi-stage linear process of Manufacturing sugar from raw sugar cane.

Overall, the production line consists of seven sequential stages, starting with Agriculturral cultivation and culminating in the preparation of refined consumer Sugar. The entire process successfully combines initial outdoor manual and Mechanical farming operation with subsequent inddor refinig methods.

First, sugar canes are cultivated in fields for a period of 12 to 18 months until the Fully mature. Once ripe, the crops are harvested either mechanically using heavy Farming vehicles or manually by hand. Next, the collected stalks are transported To a mil where they are crushed to extract the raw juice. This liquid is then passed Directly through a limestone filter to purify it and remove unwanted impurities.

Subsequently, the purified juice is heated in an evaporator, which uses high Temperatures to transform the liquid into a thick syrup. This syrup is then Transferred into a centifuge machine thst spins rapidly to separte the sugar Crystals from the remaining liquid. In the final stage, these newly isolated crystald Undergo systematic drying and colling to create the finished commercial sugar Product.

Task Achievement / Task Response: Band 7.5

The response gives a clear account of the process and includes its key stages, from cultivation for 12–18 months through harvesting, crushing, purification, evaporation, centrifuging, and drying and cooling. The overview correctly identifies seven stages and the progression from growing cane to finished sugar. Useful details include the two harvesting methods and the separation of crystals from the remaining syrup. This is a strong, well-focused summary. To make the account more fully precise, avoid adding details not shown in the diagram, such as describing the sugar as “refined,” “commercial,” or the cane as “fully mature”; these are plausible but not specified. The description of the final product could also stay closer to the diagram’s simple label, “sugar.”

Coherence and Cohesion: Band 7.0

The response is organised effectively into an introduction, an overview, and two paragraphs describing the stages in sequence. Time and sequence markers such as “First,” “Once ripe,” “Next,” “Subsequently,” and “In the final stage” make the progression easy to follow, while references such as “This liquid” and “This syrup” generally connect each stage clearly to the previous one. The overview also gives the reader a useful map before the details. Some linking is slightly mechanical because nearly every stage is introduced with an explicit transition. A few sentence-initial capitals within the body (“To,” “Directly,” “Transferred”) interrupt the flow visually. More varied, unobtrusive links and consistent sentence formatting would make the organisation smoother.

Lexical Resource: Band 6.0

There is an adequate range of process vocabulary, including “cultivated,” “extract,” “limestone filter,” “evaporator,” and “separate,” and the technical terms help convey the stages accurately. The writer also attempts less common phrasing such as “systematic, multi-stage” and “isolated crystals.” However, several spelling errors—“Agriculturral,” “inddor,” “refinig,” “centifuge,” “separte,” “crystald,” and “colling”—show inconsistent control of written vocabulary. Some choices are also less natural or more elaborate than needed: “heavy Farming vehicles” and “systematic drying” could be expressed more precisely and simply. Prefer accurate, conventional process language and proofread spelling, especially for key technical terms.

Grammatical Range and Accuracy: Band 6.5

The response uses a mix of simple and complex structures, including a relative clause in “an evaporator, which uses high Temperatures” and a purpose clause in “to separate the sugar Crystals.” Most stages are expressed in the appropriate present passive, as in “are cultivated,” “are harvested,” and “is heated,” and the meaning remains clear. Some grammatical control is less secure: “until the Fully mature” lacks a grammatical subject and verb, and “the collected stalks are transported To a mil” has an inconsistent capital within the sentence. Capitalisation is also inconsistent in several other places. The sentence patterns are generally effective, but more careful checking of complete clauses, articles, and sentence-level punctuation would improve accuracy while retaining the range already attempted.
