Our system will evaluate the answer based on this AI-generated description.

The image displays a line graph titled 'Trends in the Use of Three Energy Sources (1980-2030)', with 'Energy Usage (Index)' on the y-axis and 'Year' on the x-axis. Data points are as follows: Petrol - 1980: 50, 1990: 60, 2000: 70, 2010: 80, 2020: 90, 2030: 100. Coal - 1980: 60, peak at ~67 around 1990, low at ~60 around 2005, second peak at ~73 around 2022, 2030: 70. Natural Gas - 1980: 30, 1990: 40, 2000: 50, 2010: 60, 2020: 65, 2030: 70. Petrol and Coal intersect at an index of ~65 around 1995, while Natural Gas and Coal intersect at an index of ~68 around 2015 and again at an index of 70 in 2030.

Given the complexity of the image, the above description may not be entirely accurate.

The given line graph illustrates the use of three energy sources petrol, coal and natural gases from 1980 to 2030.

Overall, a cursory glance at the graph is enough to clear that petrol and natural gases usage saw a straight escalation from beginning to end, while coal experienced fluctuations.

To begin with, in 1980 petrol was used 20% more comapared with naturalgases(30%). As both faced a rapid incline, in 1990 these ratio increase with almost 10% (60 and 38%) respectively. Petrol rose up with same percentage every year (10%) and reach at 100, meanwhile natural gases peaked at 70 with 47 in 2000, 56 in 2010 and 62 in 2020.

Following this, coal fluctuate all the times between metion years(1980 to 2030). The percentage was 60 at starting, climbed from 1980 to 1990 at 68 then a deacrease seen from 2000 and 2010. After that coal stood at egual percentage as natural gases(70).

Task Response

The report addresses the task by describing the main trends for the three energy sources, and it includes an overview. However, there are several inaccuracies and omissions in the data, such as incorrect values for natural gas and coal, and the description of coal's fluctuations is incomplete. Some sentences are unclear or contain grammatical errors that affect clarity. To improve, ensure all key data points are accurately reported, provide a clearer structure with specific figures, and proofread for grammatical accuracy.

Coherence & Cohesion

The report has a clear overall structure with an introduction and an overview, but the body paragraphs lack logical organization and clear progression. The use of cohesive devices is limited and sometimes inaccurate, making the message difficult to follow. For example, the transition from describing petrol and natural gas to coal is abrupt, and the data points are presented in a somewhat random order. To improve, use clear topic sentences for each paragraph, and ensure that each paragraph focuses on a specific trend or time period. Additionally, use a range of linking words and phrases (e.g., 'in contrast', 'similarly', 'while', 'whereas') to show relationships between data points and trends.

Lexical Resource

The report uses some appropriate vocabulary for describing trends (e.g., 'escalation', 'incline', 'fluctuate', 'climbed'), but the range is limited and there are several inaccuracies and awkward phrasings. For instance, 'straight escalation' is not a natural collocation, and 'comapared with' and 'naturalgases' are misspelled. The report also lacks precision in describing data (e.g., 'these ratio increase with almost 10%' is unclear). To improve, expand your vocabulary for describing changes (e.g., 'steady increase', 'gradual rise', 'sharp decline', 'remain stable') and ensure correct spelling and word forms. Use more precise language to describe data points and trends. Boost vocabulary complexity to elevate the overall score.

Grammatical Range & Accuracy

The report contains numerous grammatical errors and punctuation issues that significantly affect clarity. There are subject-verb agreement errors (e.g., 'these ratio increase'), incorrect verb forms (e.g., 'reach' instead of 'reached'), and missing articles (e.g., 'the use of three energy sources petrol' should be 'the use of three energy sources: petrol'). Additionally, there are run-on sentences and unclear phrasing (e.g., 'As both faced a rapid incline, in 1990 these ratio increase with almost 10%'). To improve, focus on using a variety of sentence structures with correct grammar, and proofread for common errors such as subject-verb agreement, tense consistency, and punctuation. Practice writing clear, concise sentences that accurately convey the data.
