Band 5+: the proportion of water expended for industrial, agricultural and domestic purposes across six regions worldwide.

The report addresses the task by describing the main trends and providing some specific data. However, there are several inaccuracies and omissions that detract from the overall clarity. For instance, the introduction is incomplete (missing a verb) and contains a spelling error ('sic' instead of 'six'). The overview is somewhat vague and does not clearly state the key comparison between agricultural and industrial dominance. Some data points are inaccurate (e.g., domestic use in Africa is stated as 'below 10%' but it is 9%, which is correct, but the phrasing is imprecise; also, the report omits the exact percentages for some regions). To improve, ensure the introduction is a complete sentence, provide a clearer overview that highlights the contrast between regions, and include more precise data for all regions. Additionally, avoid vague phrases like 'approximately above 70%' and instead give exact figures. Overall, the response covers the main requirements but has some lapses in accuracy and completeness.

The report has a clear overall structure with an introduction, overview, and detailed paragraphs. However, coherence is sometimes hindered by grammatical errors and awkward phrasing (e.g., 'agriculture is account for', 'on second rank'). The use of cohesive devices is limited, and the progression of ideas could be smoother. To improve, focus on sentence clarity and use a wider range of linking words to connect ideas logically.

The vocabulary used is adequate for the task, with some appropriate terms like 'dominant', 'proportion', and 'constitutes'. However, there are errors in word choice and spelling (e.g., 'sic' instead of 'six', 'consitutes'), and the range of vocabulary is not wide. Try to incorporate more varied and precise vocabulary, and ensure correct spelling and collocations.

There are frequent grammatical errors that affect understanding, such as subject-verb agreement ('agriculture is account for'), incorrect prepositions, and missing articles. Sentence structures are often simple and repetitive. To improve, practice using a wider range of complex sentences and proofread carefully to eliminate basic errors.
