Image for topic: The diagram below shows how salt is removed from sea water to make it drinkable.

Our system will evaluate the answer based on this AI-generated description.

The image depicts a desalination process involving multiple stages: seawater intake leads to pre-treatment filter removing impurities and returning waste to sea, followed by high-pressure water forced through a membrane to separate salt, then post-treatment with lime, chlorine, and fluoride for storage and distribution to an integrated water supply system with a zoom-in on the membrane highlighting the separation of impurities, salt, and water molecules.

Given the complexity of the image, the above description may not be entirely accurate.

The illustration depicts the multi-stage process of desalinating salt from seawater, which transforms into potable water.

The five-step process begins with intake of salt from seawater and ends with an integrated water supply system. During this process, salt and other impurities are separated and returned to sea, while clean water is prepared for human use.

The process starts, how sea water is taken directly from the ocean through a salt water intake. It then passes through a pre-treatment filter, where large particles and impurities are removed, and then the filter is backwashed and returned to sea. Next, water is forced through membranes under high pressure, and then sea water is concentrated and Bach into the sea.

In the final stage, water which is recycled receives post-treatment with lime, chlorine and fluoride to make it safe for consumption. Then, stored and supplied to the integrated water supply system for public use.

Task Response

The report adequately describes the desalination process, covering the main stages from seawater intake to the final water supply system. However, there's room for improvement in terms of detail and organization. For instance, the description of the membrane filtration process could be more specific. To improve, focus on providing more precise details about each stage and ensuring a clear, logical flow in your description.

Coherence & Cohesion

The report presents a generally clear overview of the desalination process. The structure is logical, progressing from the initial intake to the final distribution. However, cohesion could be improved by using more varied linking words and phrases to connect ideas between sentences and paragraphs. For instance, in the third paragraph, the transition between the pre-treatment filter and the membrane process could be smoother. Consider using phrases like 'Following this' or 'Subsequently' to enhance the flow.

Lexical Resource

The report demonstrates a satisfactory range of vocabulary related to the desalination process. Terms like 'potable water,' 'pre-treatment filter,' 'membranes,' and 'integrated water supply system' are used appropriately. To further enhance the lexical resource, consider incorporating more specific vocabulary related to water treatment and engineering. For example, instead of 'large particles and impurities,' you could use terms like 'sediment' or 'particulate matter.' Also, varying the descriptive language (e.g., using 'purified' instead of always 'clean') could add sophistication.

Grammatical Range & Accuracy

The report generally demonstrates good grammatical control, with mostly accurate sentence structures and punctuation. However, there are a few areas where improvements can be made. For example, in the third paragraph, 'The process starts, how sea water is taken directly...' could be rephrased for better clarity and grammatical correctness (e.g., 'The process starts with seawater being taken directly...'). Also, ensure consistent verb tense usage throughout the report. Review the report carefully for any instances of subject-verb agreement errors or awkward phrasing.
