Image for topic: The given graph shows the nitrogen oxide emissions produced by four vehicles. Summarize 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 graphically represents nitrogen oxide emissions by four vehicle types (Buses, Lorries, Petrol cars, Diesel cars) across speeds (10-130 kph): Buses show a decreasing trend from ~40 g/km at 10 kph to ~28 g/km at 50 kph, followed by a subsequent rise to ~32 g/km at 130 kph; Lorries emissions start at ~35 g/km at 10 kph, decreasing to ~20 g/km at 60 kph, then ascending to ~28 g/km at 130 kph; Petrol cars maintain a steady emission rate of ~5 g/km across all speeds; Diesel cars begin at ~8 g/km at 10 kph, peaking briefly at ~10 g/km at 30 kph, then stabilize around ~9 g/km beyond 40 kph.

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

The line graph illustrates the amount of nitrogen oxide emissions created by different types of vehicles, namely buses, lorries, petrol cars, and diesel cars, measured by grams per kilometer.

Overall, buses had the highest nitrogen oxide emissions, while diesel cars recorded the lowest amount of gas emissions emitted into the environment. It is notable that while the changes of buses speed and lorries speed show strong fluctuations of nitrogen oxide, the remaining categories are almost unchanged.

Although the buses emission was 40g/km when its speed was only 10kph, it plummeted to 26g/km at 60kph. Lorries also showed a significant decrease from under 35g/km at 10kph to 23g/km at the same speed compared to buses, and hitting the lowest point of under 20g/km at 90kph. However, after decreasing sharply, both vehicles showed signs of consistent increase and reached the peak at 43g/km and 25g/km at the highest speed, respectively.

Petrol cars maintained a stable emission level of around 10g/km at the lowest speed, with the exception of its speed from 120kph to 130kph. Along with that, at 10kph diesel cars also produced a small amount of nitrogen oxide emissions at 7g/km and remained stable until the highest speed.

Task Response

The report adequately addresses the task by summarizing the main features of the graph and making some comparisons. The overall trends are identified, and some specific data points are mentioned. However, there are some inaccuracies in the data reported (e.g., diesel and petrol car emissions). To improve, ensure all data cited is accurate and consider a more structured approach to comparing and contrasting the different vehicle types.

Coherence & Cohesion

The report is generally well-organized with a clear introduction, overview, and detailed paragraphs. However, some transitions could be smoother to improve the flow of information. For example, in the third paragraph, the connection between the decreasing emissions of buses and lorries and their subsequent increase could be more explicitly linked. Also, the final paragraph feels somewhat disconnected from the previous ones; consider integrating the information about petrol and diesel cars more cohesively into the overall narrative.

Lexical Resource

The report demonstrates a good range of vocabulary related to the topic of emissions and vehicle types. However, there are instances where the word choice could be more precise or varied. For example, using synonyms for 'decrease' and 'increase' could enhance the lexical richness. Also, consider using more specific vocabulary to describe the trends, such as 'gradual decline' or 'sharp increase,' where appropriate. Pay attention to vocabulary repetition to improve the overall score.

Grammatical Range & Accuracy

The report exhibits a mix of simple and complex sentence structures. However, there are some grammatical errors and phrasing issues that affect clarity. For example, in the second paragraph, 'diesel cars recorded the lowest amount of gas emissions emitted into the environment' is somewhat redundant. In the third paragraph, there are some awkward phrasings. Pay closer attention to subject-verb agreement, correct tense usage, and sentence structure to improve grammatical accuracy.
