Task Response

The report covers the main features of the pie charts and provides relevant data. However, there are some inaccuracies in the data reported (e.g., hydroelectric power and nuclear power trends). Also, the writing could be more concise and accurate. For example, avoid phrases like 'offosite times' and ensure correct tense usage. To improve, focus on accurate data representation and clarity in language. The report falls short of the required 150 words.

Coherence & Cohesion

The report demonstrates some organization, but the flow of information is disrupted by grammatical errors and awkward phrasing. Paragraphing is present but could be used more effectively to group related ideas. Use cohesive devices more accurately to link ideas within and between sentences.

Lexical Resource

The vocabulary is limited and sometimes inaccurate ('offosite times', 'rato'). There is an attempt to use descriptive language, but it is not always successful. Focus on expanding your vocabulary related to describing data and trends.

Grammatical Range & Accuracy

The report contains numerous grammatical errors, including incorrect verb tenses, subject-verb agreement issues, and misuse of prepositions and articles. Sentence structure is often awkward and unclear. Work on improving your understanding of basic grammar rules and sentence construction.
