@mokong are you preparing for PTE exams? Well, to give my share on how you will describe this graph, here is my suggestion:
The line graph projected on the screen is the presentation of variables showing percentage of world population between Asia and Europe.
Based on the line trend, Asia's population had gradually fell from year 1850 from 64% and continue to drop dramatically until 1950 estimated at 56%. Finally, there's a gradual increase from 58-62% approaching year 2000 and continually stabilized at 60% thereafter. On the other hand, Europe had steadily increased from 20-25% from year 1750 to 1900 and slightly dropped back to 20% year 1950. Surprisingly, population had plummeted from 20% down to 9% observed until year 2000.
This graph was concise and accurate and can be used as a reference for future studies particularly in comparison between Asia and Europe population trend analysis.
Hope this helps!
