The line graph illustrates the percentage of four energy supplies, spanning from 1990 to 2020.

Overall, it is clear that renewable energy experienced a rise in distributing of energy from 1990 to 2020, with projections indicating a further increase at 10 to 20 .Coal is anticipated to have the highest percentage by 2010 with figures 40 to 45 but starting from 2010 its declined approximately 40, followed by natural gas from 30 to 25 and nuclear power.

The distribution of energy sources of nuclear power showed consistent downward over the 3 decades, starting at 20 in 1990 and reaching nearly 15 by 2020. Similarly, natural gas witnessed a comparable pattern, beginning at 30 and was predicted to almost 23 in 2020. After that, it witnessed a fluctuating pattern in the 2 decade.

Coal displayed a modest increase in its graph from about 40 in 1990 to just under 50 in 2010. Conversely, starting at 45 in 2010 was dropped to 42 in 2020.

Task Response

The report attempts to address the task but contains several inaccuracies and omissions. It misinterprets the data (e.g., describing trends as projections, incorrect figures for natural gas and nuclear power) and includes irrelevant information about future predictions. The overall structure is present, but the data presentation is often unclear or incorrect, detracting from task achievement. To improve, focus on accurately describing the trends for each energy source over the given period, avoid speculative language, and ensure all data points are correctly reported.

Coherence & Cohesion

The report has a logical structure with an introduction and an overview, but the flow is disrupted by unclear references and abrupt transitions. For instance, the phrase 'with projections indicating a further increase at 10 to 20' is vague and confusing. Additionally, the second paragraph mixes data from different years without clear sequencing, making it hard to follow. To improve, use clear topic sentences for each paragraph and ensure that each paragraph focuses on a specific trend or time period. Also, use cohesive devices such as 'in contrast', 'similarly', and 'over the period' to link ideas smoothly.

Lexical Resource

The vocabulary is adequate but limited, with some imprecise word choices and awkward phrasing. For example, 'distributing of energy' should be 'distribution of energy', and 'its declined' should be 'it declined'. The report also uses informal expressions like 'witnessed a fluctuating pattern' which is acceptable but could be more precise. To improve, use a wider range of academic vocabulary, such as 'accounted for', 'constituted', 'experienced a decline', and 'remained relatively stable'. Also, avoid repetition by using synonyms for 'percentage' and 'energy sources'. Boost vocabulary complexity to elevate the overall score.

Grammatical Range & Accuracy

The report contains several grammatical errors and punctuation issues that affect clarity. For example, 'its declined' should be 'it declined', and 'was dropped' should be 'dropped'. There are also missing articles and incorrect prepositions, such as 'in distributing' instead of 'in the distribution'. The sentence 'Coal is anticipated to have the highest percentage by 2010 with figures 40 to 45 but starting from 2010 its declined approximately 40' is grammatically incorrect and confusing. To improve, focus on subject-verb agreement, correct verb tenses, and proper use of articles. Also, ensure that each sentence is complete and clearly expresses a single idea.
