答案     The line graph indicates the changes of energy demand and the energy available from fossil fuels in Freedonia for 20 years to 2005.
    According to the line graph, the amount of energy available from fossil fuels increased significantly from approximately 3.5 units (each unit is equivalent to 100 billion megajoules) in 1985 to 6.5 in 1995, which was its peak. But after that it dropped sharply until 2000 when it remained stable at about 2.5 units until 2005.
    On the contrary, between 1985 and 1990, the demand for energy decreased gradually from 5 units to nearly 2 units. There was little change in this number from 1990 to 1995. Since 1995, it jumped suddenly. In 2000, this number increased to less than 4 units but after then it will go up more rapidiy and reached 7 units in 2005.
    It can be seen from the line graph that energy available was higher than energy demand from 1986 to 1999. However, after 1999, energy available was unable to keep up with energy demand.
