The diagram illustrates how rainwater is gathered and treated to be used as drinking water in Australian town.

As depicted in the diagram, the process includes several stages starting with the collection of rainwater to water and chemicals treatment and concluding with the potable water ready to be used.

Task Response

The response provides a good overview of the main features of the diagram, covering the stages of rainwater collection, treatment, and conversion to drinking water. However, some key details are missing, such as the mention of a water filter and the flow direction indicated by arrows. The word count is also slightly below the minimum requirement. The report falls short of the required 150 words.

Coherence & Cohesion

5.5

The report is generally coherent and cohesive, with a clear progression of ideas from rainwater collection to treatment and conversion to drinking water. Paragraphing is appropriately used to separate different stages of the process. Some minor issues with sentence structure and transitions slightly affect the overall flow.

Lexical Resource

4.5

There is a good range of vocabulary used to describe the process of rainwater treatment, including terms like 'filtration,' 'chemicals treatment,' and 'potable water.' However, there are instances of awkward phrasing and inaccuracies, such as 'specialized machine for filtration' instead of 'water filter.' More precise and varied word choices could enhance the lexical resource.

Grammatical Range & Accuracy

4.5

The report demonstrates a mix of simple and complex sentence structures, contributing to a moderate range of grammatical structures. However, there are issues with subject-verb agreement ('chemicals is added'), prepositions ('assist the phase by'), and tense consistency ('having been converted'). Punctuation and sentence mechanics are generally accurate but could be improved for a higher score.
