Task Response

The report covers the main features of the data, noting the changes in energy sources between 1980 and 1990. However, it could benefit from a more structured overview and a more comprehensive comparison of the data. To improve, consider including specific data points to support your statements and ensure accuracy in reporting the percentages. The report falls short of the required 150 words.

Coherence & Cohesion

The report is generally well-organized with a clear introduction, body, and conclusion. The information is presented logically, and the main trends are identified. However, the transitions between sentences and ideas could be smoother to enhance the flow. Consider using transition words or phrases to connect related ideas more explicitly. For example, when discussing the changes in energy sources, you could use phrases like 'In contrast' or 'Similarly' to link the information more effectively.

Lexical Resource

The report demonstrates a sufficient range of vocabulary to describe the data. However, there's room to enhance the precision and sophistication of the language used. For instance, instead of saying 'being used more,' you could use phrases like 'experienced an increase in usage' or 'saw greater utilization.' Also, consider using synonyms for common words like 'percentage' and 'source' to add variety to your writing. Boost vocabulary complexity to elevate the overall score.

Grammatical Range & Accuracy

The report demonstrates a good command of grammar with only minor errors. However, attention to detail in sentence structure and verb tense consistency could further improve the accuracy. For example, in the first paragraph, consider rephrasing 'This graph shows difference between main sources' to 'This graph illustrates the differences between the main sources.' Additionally, ensure that verb tenses are consistent throughout the report to maintain clarity.
