Task Response

The report covers the requirements of the task, providing a general overview and some specific details about the energy sources in the USA in 1980 and 1990. However, there are some omissions and lapses in the accuracy of the data reported. To improve, ensure that all data points are accurately represented and consider a more structured approach to comparing and contrasting the two pie charts.

Coherence & Cohesion

The report demonstrates an adequate attempt to organize the information, but the overall structure could be improved for better flow. The 'Overall' paragraph is somewhat unclear and could be more concise and focused on the main trends. Transitions between sentences and paragraphs are sometimes abrupt, affecting the logical progression of ideas. Consider using more varied cohesive devices to link ideas and improve the clarity of the report.

Lexical Resource

The vocabulary used is generally appropriate but lacks sophistication. There is some repetition of words like 'percent' and 'percentage.' Try to incorporate a wider range of vocabulary to describe the data and trends more precisely. For example, instead of always using 'percent,' consider using terms like 'proportion,' 'share,' or 'fraction.' Also, explore synonyms for 'highest' and 'lowest' to add variety to your writing. Boost vocabulary complexity to elevate the overall score.

Grammatical Range & Accuracy

The report contains several grammatical errors, including incorrect word usage ('persent' instead of 'percent'), subject-verb agreement issues, and awkward phrasing. Sentence structure is relatively simple, and there is limited use of complex sentence structures. To improve, focus on proofreading carefully for grammatical errors and practicing a wider range of sentence structures. Pay attention to correct spelling and ensure that your sentences are clear and grammatically sound.
