The given graph shows the nitrogen oxide emissions produced by four vehicles. Summarise the information by selecting and reporting the main features and make comparisons where relevant.
SAMPLE ANSWER
The given line graph compares the nitrogen oxide emissions from buses, lorries, petrol cars and diesel cars. It can be seen from the graph that the maximum emissions are from buses and the emissions vary with the speed of the vehicle.
At a speed of 10kph, buses produce 40 g/km emissions. However, as the speed of the bus increase to 60 kph, the emissions decrease gradually and reach a little over 25 g/km. It is interesting to note that if the speed of the bus goes beyond 60 kph, the emissions again begin to rise, and at a speed of 130 kph the emissions are over 40 g/km. Lorries also show a similar pattern but the overall emissions are lower than that from buses. Another point of difference is that emissions decrease till the speed of 90kph and only after that, begin to rise again.
The emissions from diesel car and petrol car show a similar pattern and also do not show much variation with speed. Emissions from diesel car are the least and hover around 5 g/km and those from petrol car are around 10g/km.
Overall, emissions from lorries and buses follow a similar pattern and those from diesel and petrol cars follow a similar pattern.
