You should spend about 20 minutes on this task The given graph shows the nitrogen oxide emissions produced by four vehicles. Summarize the information by selecting and reporting the main features and making comparisons where relevant. You should write at least 150 words.

The line graph illustrates the amount of nitrogen oxide emmisions produced by buses, petrol cars, diesel cars, and lorries. Overall, while busses and lorries witnessed increases and decreases from 10 to 130 KPH, diesel cars and petrol cars remained unchanged. The proportion of busses produced nitrogen oxide witnessed a dramatic drop from 40 to about […]

The given graph shows how speed can affect emissions of nitrogen oxide produced by four different vehicles. Overall, it is evident that disel and petrol car relatively emit an unchanging amount of nitrogen oxide regardless of speed, while the opposite is true for busses and lorries. Busses and lorries have rather varying nitrogen oxide emissions […]

The line graph illustrates the amount of nitrogen oxide emissions from four kinds of transportation. Overall, it is clear that there is a similar trend in buses and lorries, with buses witnessing the most dramatic rise. While having some fluctuations, diesel and petrol cars remain stable at a lower figure. There is a sharp decrease […]
