The diagram details the process of producing olive oil.
Sample Response
The diagram delineates the process by which olive oil is made. The production can be divided into three main stages3 main groups beginning withbeginning with initial harvesting and treatment, followed by creation of the oil, and lastly storage for future use.
The process begins with the olives being harvested from trees and placed in a collection vat. The olives must then be stripped of their leavesde-leafed and washedcleaned with water before they are put into an olive mill to crush them into olive paste. The paste is then put through a malaxer set to a temperature below 27 °Cnot greater than 27 °C. After the malaxer, paste then enters a centrifugal press which creates virgin oils.
NextSubsequent to this, the virgin oils are then either separated (with waste water being discharged) or decanted, which filters out both solids and water. Regardless of the method of separation, the oil from both branches is storedboth products are reserved in a storage tank at the end of the processto finish the steps detailed in the diagram.
Why this response received Band 7.5
The response clearly follows the production sequence and uses precise process vocabulary, with an effective overview and generally controlled complex sentences. Its main limitation is incomplete coverage of the centrifugal-press stage: the pomace by-product and its possible further processing are omitted, while the final reference to both products is slightly unclear. Prioritise a fully accurate account of every major output and branch shown in the diagram.
IELTS Writing Criteria Scores
Task Achievement
The report presents a clear overview and accurately covers the main oil-production sequence, but it omits the pomace output and its possible further processing.
Include every major branch from the centrifugal press and distinguish clearly between the oil, wastewater, solids, and pomace outputs.
Coherence and Cohesion
Information progresses logically from harvesting to storage, although repeated sequencing language and the reference to both products slightly reduce cohesion.
Use more precise referencing at the final branch and reduce redundant combinations such as subsequent to this and then.
Lexical Resource
A broad and mostly precise process vocabulary is used effectively, including malaxer, centrifugal press, decanted, and discharged.
Refine the few awkward collocations, replacing creation of the oil and products are reserved with more natural process-report wording.
Grammatical Range and Accuracy
A varied range of complex structures is handled with strong control, with only occasional article and phrasing lapses.
Polish small details such as adding the article in after the malaxer and removing redundant sequencing words.
