Task Response

The report fully satisfies the requirements of the task. It provides a clear overview of the main trends, effectively highlighting the shift in dominance from China to India. The data is presented logically, with appropriate comparisons made between the years and the different countries. The use of varied vocabulary to describe changes (e.g., 'decline considerably', 'increase steadily', 'overtaking') and the accurate use of tense for projections contribute to a high-quality response.

Coherence & Cohesion

The report is exceptionally well-organized. The introduction clearly defines the scope, the overview provides a high-level summary of the main trends, and the body paragraphs are logically divided into historical data and future projections. Cohesive devices such as 'Overall', 'In contrast', 'Meanwhile', and 'According to' are used naturally to guide the reader through the comparisons without being repetitive or intrusive.

Lexical Resource

The vocabulary used is sophisticated and highly appropriate for an academic report. There is excellent variety in how proportions and changes are described, using terms like 'accounted for', 'represented', 'overtaking', 'forecast to decrease', and 'relatively stable'. The use of synonyms for 'percentage' (e.g., 'share', 'proportion', 'figure') demonstrates a high level of lexical control.

Grammatical Range & Accuracy

The report demonstrates a wide range of grammatical structures with full accuracy. The writer effectively uses a mix of past tenses for historical data and future forms (e.g., 'is expected to', 'is predicted to', 'is forecast to') for projections. Complex sentence structures, including subordinate clauses and comparative structures, are used flawlessly to convey relationships between different data points.
