Summarise the infonnation by selecting and reporting the main features, and make comparisons where relevant.

Past and projected future overweight rates in selected OECD countries

Student answer (Band 7.5)

The line graph illustrates historical data and future projections for the proportion of overweight individuals across nine selected OECD nations between 1970 and 2020.

Overall, it is clear that all surveyed countries experienced an upward trend in overweight rates over the period of 1970 to 2020. The United States consistently recorded the highest figures throughout, whereas Korea remained the nation with the lowest proportion.

Looking at the countries with the highest rates, the USA began at approximately 47% in 1970, experienced a slight dip in 1980 (around 43%), and then rose steadily to reach a peak projected rate of nearly 75% by 2020. England and Australia showed sharp increases starting from the 1990s; England escalated from around 47% in 1990 to roughly 69% in 2020, while Australia’s rate climbed steadily along a similar trajectory to reach about 64%. Spain and Canada followed a comparable pattern, both converging at approximately 55% by the end of the period.

Regarding the remaining nations, Austria, Italy, and France showed moderate increases. Austria stood at roughly 39% in 1980 and rose marginally to 46% by 2020, closely matched by Italy and France at around 45% and 44% respectively. In contrast, Korea had the lowest rate, beginning at 25% in 1998 and climbing steadily to finish at about 35% in 2020.

AI examiner evaluation

Task Achievement / Task Response: Band 7.5

The student covers all parts of the task well, providing a clear overview and effectively reporting the main features and trends across the nine countries. Data is cited accurately from the visual text, such as noting the USA's high figures reaching nearly 75% by 2020 and Korea's status as the lowest starting at 25% in 1998. Comparisons are made appropriately throughout the body paragraphs, grouping nations logically by their trajectories. The response is fully developed and satisfies all requirements of Academic Task 1.

Coherence and Cohesion: Band 7.5

The text is logically organized with a clear overall progression. An effective introduction is followed by a strong overview statement that captures the main trends. Body paragraphs are well-structured, grouping countries by similar patterns (highest rates, moderate increases, and lowest rates). Cohesive devices such as 'whereas', 'regarding', 'in contrast', and referencing pronouns are used flexibly and appropriately without becoming mechanical. Paragraphing is used sufficiently and effectively to separate distinct categories of data.

Lexical Resource: Band 7.5

The response demonstrates a wide and flexible range of vocabulary suitable for describing graphical data. Phrases such as 'upward trend', 'consistently recorded', 'sharp increases', 'climbing steadily', and 'moderate increases' are used naturally. Less common lexical items and precise reporting verbs show a good awareness of style and collocation. Word choices are accurate, and spelling is flawless throughout the text.

Grammatical Range and Accuracy: Band 7.5

A wide variety of complex sentence structures is employed successfully. The majority of sentences are error-free, demonstrating excellent control over subordination, relative clauses, and participial phrases (e.g., 'England escalated from around 47% in 1990 to roughly 69% in 2020, while Australia’s rate climbed steadily along a similar trajectory'). Punctuation is accurate, and only very minor or occasional slips can be found, which do not impede communication in any way.
