The response covers the main trends with a clear overview and largely accurate figures matching the graph. However, it incorrectly describes the US and Australia as maintaining a steady increase after 2005, when Australia stayed flat, and calls the UK decline continual in the overview despite acknowledging its initial plateau in the detail.
7.0Information is logically sequenced from overview to year-by-year detail with effective linking devices such as 'Similarly', 'In contrast', and 'on the other hand', and progression is consistently clear.
7.0Vocabulary is varied and generally appropriate for describing trends, including 'the trend reversed' and 'persisted'. Precision is weaker when 'steady increase' is applied to Australia's stable figures and when students themselves, rather than their number, are described as decreasing or remaining at a numerical level.
