▶ Your Answer : The line graph indicates quantities of good transported in the UK between 1974 and 2002 by four different modes of transport. To begin with, there are no huge changes for the first four years from 1974 to 1978. After that, goods transported by road and rail decreased more than ten million tonnes, respectively, for four years. By contrast, goods transported by pipeline and water increased at the same period of time. Especially, water transportation increased dramatically comparing to pipeline transportation. For twelve years from 1982, water tranport has slight fluctuations while pipline shows steady increase until 1998. By contrast, road and rail transportion shows dramatic fluctuation between the period of 1982 and 1998. Moreover, for the last four years, pipeline tranport maintained 21 millions tonnes while road, water and rail transport increased dramatically. Overall, road transport, water transport, rail transport showed the fluctuation phenomenon for past thirty four years, but pipeline is the only transport that did not decrease for thirty four years. |
