Band 6+: The line graph shows the percentages of Australian exports with four countries. The graph below shows the percentage of Australian exports to 4 countries from 1990 to 2012.

The report adequately addresses the task by describing the main trends in sugar production and consumption over the given period. It correctly identifies the overall fluctuation in production and the steadier rise in consumption, and it includes specific data points for key years. However, there are some omissions and minor inaccuracies: the report does not mention the initial production value precisely (it says 'roughly at 19' instead of 18.2), and it omits some years (e.g., 2002, 2004, 2008, 2010) where trends could be highlighted. Additionally, the phrase 'production started at a higher proportion than the other' is awkward, and the report could be more precise in describing the consumption trend (e.g., noting that consumption remained around 20-21 million tonnes from 2003 to 2010 before rising to 23 in 2011). Overall, the response covers the main requirements, but a more systematic overview and clearer data referencing would enhance clarity and completeness.

The report has a clear overall structure with an introduction, an overview, and two body paragraphs. However, the flow is sometimes disrupted by abrupt transitions and unclear referencing (e.g., 'the other', 'that decade'). The overview could be more concise and better integrated. To improve, use a wider range of cohesive devices (e.g., 'in contrast', 'subsequently') and ensure each paragraph has a clear central topic. Also, avoid informal phrases like 'by the end of the graph' and instead use 'by the end of the period'.

The report uses some appropriate vocabulary for describing trends (e.g., 'fluctuated', 'rose steadily', 'rocketed', 'dropped'). However, there is repetition (e.g., 'revealed', 'showed') and some imprecise word choices (e.g., 'proportion' instead of 'figure', 'demonstrated' instead of 'reached'). To achieve a higher score, expand your range of synonyms and use more precise terms (e.g., 'peaked at', 'declined sharply', 'remained stable'). Also, ensure correct collocations (e.g., 'stood at' not 'stood roughly at').

The report demonstrates a mix of simple and complex sentence structures, but there are several grammatical errors and punctuation issues that affect clarity. For example, 'Sugar production' should be 'sugar production' (lowercase), 'production started at a higher proportion' is awkward, and 'revealed similar level' should be 'revealed a similar level'. There are also missing commas and inconsistent capitalization. To improve, proofread carefully, use a wider range of complex structures (e.g., relative clauses, conditionals), and ensure subject-verb agreement and article usage are correct.
