Image for topic: The graph shows the nitrogen oxide emmisions produced by four vehicles.

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

The image presents a line graph of nitrogen oxide emission (g/km) versus speed (kph) for four vehicles, with the y-axis ranging from 0 to 45 and the x-axis from 10 to 130. For the Diesel car, emissions in g/km at speeds of 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, and 130 kph are approximately: 6.5, 6, 5.5, 5.2, 5.1, 5, 5, 4.9, 4.9, 4.9, 4.8, 4.8, and 4.8. For the Petrol car, the corresponding emissions are: 11, 11.2, 10.5, 10, 10.1, 9.5, 9.5, 9, 9, 9.5, 10, 10.5, and 11.5. For Lorries, the emissions are: 33, 31, 29, 27, 25, 23, 20, 18, 16, 18, 20, 22, and 24. For Buses, the emissions are: 40, 37, 34, 32, 30, 26, 29, 32, 34, 36, 38, 40, and 42.

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

The provided graph illustrates the amount of nitrogen oxide emissions release into the environment through four vehicles, namely: diesel car, petrol car, lorries, and buses.

Overall, it is apparent from the graph that the amount of emissions from trucks and buses decreases as they begin to accelerate, however, increases when they are at top speed. Additionally, the emissions of diesel and petrol car are remain unchanged at all speed.

According to the graph, lorries and buses show nearly the same trend. Buses stand at exactly 40 g/km nitrogen oxide at 1 kph initially, decline gradually to just over 25 g/km when the speed is at 6 kph. From this point, the emissions grow proportionally with the speed, reaching 42 g/km at 130 kph. Lorries start with 33 g/km decrease steadily to roughly 15 g/km at 9 kph, then rise to 24 g/m at 130 kph, about 18 g/km less than buses.

In contrast, diesel and petrol car demonstrate a stable trend. Starting with 7 g/km and 11 g/km, these two vehicles fluctuate and nearly stabilize when the speed increases. When they come to their peak speeds, the amount of nitrogen emits just around 5 and 11 g/km, become the two most environmental-saving transportations among the four.

Task Response

The report covers the requirements of the task, providing an overview of the nitrogen oxide emissions from the four vehicles. There are some inaccuracies in the data reported, such as the speeds mentioned in the third paragraph. Also, the second paragraph could be more precise in describing the trends. To improve, ensure greater accuracy in data representation and provide more specific details about the trends observed in the graph.

Coherence & Cohesion

The report demonstrates an adequate attempt to organize information, but there are instances where the flow could be improved. Transitions between ideas are not always smooth, and the paragraphing could be more effective in grouping related information. For instance, the overall trends could be more clearly stated at the beginning, and the comparison between vehicles could be more explicitly linked. Consider using cohesive devices more effectively to guide the reader through the information.

Lexical Resource

The report uses a sufficient range of vocabulary to convey the information, but there are opportunities to enhance the precision and sophistication of word choices. Some phrases are slightly awkward or could be expressed more concisely. For example, 'amount of emissions from trucks and buses decreases as they begin to accelerate, however, increases when they are at top speed' could be rephrased for clarity and impact. Focus on using more precise and varied vocabulary to describe trends and comparisons.

Grammatical Range & Accuracy

The report demonstrates a reasonable command of grammar, but there are noticeable errors that affect clarity. Subject-verb agreement issues, incorrect tense usage, and awkward phrasing are present. For example, 'the emissions of diesel and petrol car are remain unchanged' contains errors. Pay closer attention to grammatical accuracy and sentence structure to improve the overall quality of the writing. Proofreading carefully can help identify and correct these errors.
