Image for topic: The line graph below shows changes in the proportion of energy produced from different sources in a country from 1980 to 2015. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

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

The image displays a line graph titled "Energy production by source (1980–2015)", showing the percentage of energy production against the year. In 1980, Fossil fuels were at 70%, Nuclear at 10%, Renewables at 5%, and Other sources at 15%. By 1985, Fossil fuels were approximately 68%, Nuclear 13%, Renewables 8%, and Other sources 12%. In 1990, Fossil fuels were at 65%, Nuclear 16%, Renewables 11%, and Other sources 10%. In 1995, Fossil fuels accounted for about 62%, Nuclear 19%, Renewables 14%, and Other sources 8%. Around 2000, Fossil fuels were at 58%, Nuclear 21%, Renewables 17%, and Other sources 7%. In 2005, the data points were: Fossil fuels 55%, Nuclear 22%, Renewables 20%, and Other sources 5%. For 2010, the values were approximately: Fossil fuels 52%, Nuclear 23%, Renewables 22%, and Other sources 5%. Finally, in 2015, Fossil fuels were at 50%, Nuclear at 25%, Renewables at 24%, and Other sources at 3%.

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

The line graph illustrates the change in energy production from fossil fuels, renewables, nuclear, and other sources over a thirty-five-year period between 1980 and 2015.

Overall, energy production from fossil fuels constituted the largest share throughout the period. By contrast, nuclear and renewables accounted for the smallest percentage of energy production, they experienced slight growth at the end of the timeframe.

Fossil fuels made up the majority of produced energy at around 70%. However, this figure gradually decreased, reaching 50% by the end of the period. Nuclear accounted for the 10% of generated energy in 1980, before climbing to 20% in 1995. A similar pattern can be seen in renewables, which represented roughly 5% in 1980 and followed a steady growth, reaching 15% at the end of the period. Other sources meanwhile, represented around 16% in 1980, but feel markedly to 5% in 2010.

After certain percentage of energy production by other sources remained steady until 2010 and reached a reduction to 3% in 2015.

Task Response

The report covers the main requirements of the task and provides a clear overview of the trends. The main features are identified, and comparisons are made between the different energy sources. However, there are some inaccuracies in the data reporting (for example, stating renewables reached 15% when the data suggests it reached 24%) and some grammatical issues in the final paragraph that affect the flow. To improve, ensure that the data cited matches the visual information more closely and work on the cohesion of the concluding sentences to avoid fragmented structures.

Coherence & Cohesion

The report follows a logical structure with an introduction, overview, and body paragraphs. However, there are issues with sentence connectivity and cohesion. The overview contains a comma splice (joining two independent clauses with only a comma), which disrupts the flow. Additionally, the final paragraph begins with a fragment ('After certain percentage...') that lacks a main clause, making the conclusion feel disconnected and grammatically incomplete. To improve, ensure that each paragraph has a clear purpose and that transitions between ideas are smooth and grammatically sound.

Lexical Resource

The vocabulary used is generally appropriate for an academic report, with good use of verbs like 'constituted', 'accounted for', and 'represented'. There is an attempt to vary the language used to describe trends. However, there is a significant spelling/word choice error where 'feel' was used instead of 'fell'. To reach a higher band, aim for more precise collocations and ensure that word choices are consistently accurate throughout the text.

Grammatical Range & Accuracy

The report demonstrates a mix of simple and complex sentence structures, but grammatical errors are frequent enough to impact clarity. Notable issues include the comma splice in the overview, the incorrect use of articles (e.g., 'the 10%'), and the sentence fragment at the end of the report. The phrase 'reached a reduction to' is also somewhat awkward. Focus on mastering sentence boundaries (avoiding run-on sentences) and ensuring that every sentence contains a subject and a finite verb to form a complete thought.
