The line chart presents three sources of air pollutants in Portugal between 2005 and 2020.

Overall, in Portugal, industry contributes significantly to air pollution, whereas household has the least influence. Although air pollutants from industry and household have decreased throughout the period, air pollutants from transportation have increased from 2005 to 2020.

In 2005, air pollutants from industry were around 5 million tonnes. This figure then witnessed a significant drop, reaching to its lowest at approximately 2.5 million tonnes in 2020. Air pollutants arising from household also demonstrated a similar trend. It started around 1 million tonnes in 2005, and steadily dropped to below 1 million tonnes by 2008 and plateued at this level until 2011. Afterwards, it strated to gradually decrease, recording its lowest emission at nearly 0.5 million tonnes in 2017, and remained steady at this level until 2020.

A different pattern can be observed in air pollutants from transportation. The air pollutants arising from this source were roughly 1 million tonnes, in 2005. This figure hovered around this level until 2011, and started to dramatically increase, reaching its peak at nearly 2 million tonnes in 2020.

Task Response

7
The report covers the main trends and makes relevant comparisons. However, there are some inaccuracies in the data reported (e.g. '2.5 million tonnes in 2020' vs '2 million tonnes in 2020', '0.5 million tonnes in 2017' vs '0.9 million tonnes in 2014, and 0.8 million tonnes in 2020'). To improve, ensure greater accuracy in reporting the data and consider including more specific details to support the overall trends.

Coherence & Cohesion

7
The report is generally well-organized with a clear overview and supporting paragraphs. The progression of ideas is logical. However, cohesion could be improved by using a wider range of cohesive devices to link ideas within and between paragraphs more smoothly. For example, consider using more varied transition words and phrases to enhance the flow of information.

Lexical Resource

7
The report demonstrates a good range of vocabulary, appropriate for the task. There is room to enhance the sophistication of word choices to describe trends and quantities more precisely. For instance, instead of 'witnessed a significant drop,' consider using more specific terms like 'plummeted' or 'declined sharply.' Also, ensure that the vocabulary used accurately reflects the data presented in the graph.

Grammatical Range & Accuracy

7
The report demonstrates a good command of grammar with a variety of sentence structures. While there are only a few grammatical errors, attention to detail in proofreading can further improve accuracy. Focus on ensuring correct tense usage and subject-verb agreement throughout the report. Also, pay attention to the accuracy of preposition usage.
