The two pie charts compare how the components of electricity generation in Germany evolved from 1980 to 2010.

Overall, the total units of electricity increased significantly over the 30 years. However, figures for the majority of the sources decreased, except significant increase in the yellow and a slight in the black sector. The proportion of the grey sector remained the same.

The unit of the yellow section rose dramatically from 20 to 155 between the years of 1980 and 2010. Likewise, the number in black had a slight increase from 22 to 27. On the other hand, the proportion of green was reduced markedly from 28 to only 2 units. Similarly, the units of blue section had a marginal drop from 7 to 2.

In contrast, grey remained relatively stable at 28 compared to the other sectors between 1980 and 2010.

Task Response

The report covers the main features of the pie charts and provides relevant comparisons between the two years. However, there are some inaccuracies in the data reported (e.g., identifying colors instead of sources, misreporting values). To improve, ensure data accuracy and use specific source names instead of color references for clarity. The report falls short of the required 150 words.

Coherence & Cohesion

The report is generally well-organized with a clear overall structure, including an introduction, overview, and detailed paragraphs. The progression of ideas is logical, but the use of color references (yellow, black, grey, green, blue) without explicitly stating what each color represents initially can be confusing for the reader. To improve coherence, consider explicitly naming the source of electricity each color represents at the beginning or within the relevant paragraphs. Transition words are present but could be used more effectively to enhance the flow between sentences and paragraphs.

Lexical Resource

The report demonstrates a good range of vocabulary related to describing proportions and changes. Terms like 'significantly,' 'dramatically,' 'slight increase,' 'reduced markedly,' and 'marginal drop' are used appropriately. However, there's room to incorporate more varied and precise vocabulary to describe the data. For instance, instead of repeatedly using 'units,' consider using 'percentage,' 'proportion,' or 'amount' depending on the context. Also, try to avoid vague terms like 'section' and use the actual source of electricity. Boost vocabulary complexity to elevate the overall score.

Grammatical Range & Accuracy

The report demonstrates a good command of grammar with a variety of sentence structures. There are a few minor errors, but they do not significantly impede understanding. Pay attention to subject-verb agreement and correct use of articles. For example, 'The unit of the yellow section rose dramatically' could be improved to 'The amount of electricity generated from coal rose dramatically.' Review and correct any instances of imprecise language to enhance clarity and accuracy.
