The line graph compares the numbers of people who drank tea and coffee between 2000 and 2020.

Overall, tea consumption experienced a substantial upward trend throughout the period, whereas the number of people drinking coffee declined steadily. Notably, tea overtook coffee in terms of the number of consumers during the period.

In 2000, the number of tea drinkers stood at 20, compared with 40 for coffee. The figure for tea then rose steadily, reaching 30 in 2005 and 45 in 2010. It continued to increase over the following five years, reaching 55 in 2015, before peaking at 70 in 2020.

By contrast, coffee consumption followed the opposite pattern. Starting at 40 in 2000, the figure fell gradually to 35 in 2005 and 30 in 2010. It subsequently declined to 25 in 2015 and reached a low of just 20 by 2020.

Task Response

The report appropriately addresses the task by comparing the number of tea and coffee drinkers over the period, and it provides a clear overview of the main trends. The data is presented in a logical structure with specific figures for each year. However, there are some minor omissions and lapses: the report does not mention the units of measurement (e.g., millions or thousands) for the number of people, and it does not explicitly state that tea overtook coffee at a specific point in time. Additionally, the report could have included a brief comparison of the overall changes (e.g., the total increase for tea versus the total decrease for coffee) to enhance the summary. Overall, the response is well-organized and covers the main features, but these small gaps prevent it from achieving a higher band. The report falls short of the required 150 words.

Coherence & Cohesion

The report is exceptionally well-organized and easy to follow. The introduction clearly paraphrases the task, and the overview effectively summarizes the main trends. The body paragraphs are logically divided into tea and coffee consumption, with clear progression over time. Cohesive devices are used naturally and effectively, and paragraphing is skillfully managed.

Lexical Resource

The vocabulary is precise, varied, and appropriate for the task. The report uses a wide range of lexical items such as 'experienced a substantial upward trend,' 'declined steadily,' 'overtook,' 'stood at,' 'peaking at,' and 'reached a low of.' These choices demonstrate natural and sophisticated control of language, with no repetition or inappropriateness. Boost vocabulary complexity to elevate the overall score.

Grammatical Range & Accuracy

The report demonstrates a wide range of grammatical structures used with full flexibility and control. Sentences are varied in structure, including complex sentences with subordinate clauses and participial phrases. Punctuation and grammar are used correctly throughout, with no errors detected. The report is a model of grammatical accuracy.
