The bar graph compares the telephone calls duration in billion of minutes , for the fixed
line both for local and international calls and for mobile calls , in UK from 1992 to
2002 .

It can be clearly seen that the fixed line local calls has gradually increased in the
period of 1995 to 1999 , reaching it's peak in 1999 , increased by 18 billion of minutes
in contrast to 1995 . Ever since , a gradual decrease started until 2002 reaching an
approximate of 72 billion of minutes which is approximately equal to the initial value
in 1995 .

International call fixed line started with a low number in contrast to the local calls
in 1992 , then the numbers started to increase gradually until 2002 , an increase by 24
billion of minutes .

Mobiles calls numbers where very low in 1992 about 3 billion of minutes and started to
increase until 1999 . In 2000 the increase in mobile calls was about twice the 1999 year
and the huge increase continued until 2002 .

In conclusion , the graph shows that mobile calls affected tge fixed line calls , especially
in 2000 , 2001 and 2002 .

Hello!
Basically, this is a good report. Remember 'billion minutes' not 'billion of minutes'! The only real problem is with the conclusion. You claim that the increase in mobile call time affected the call time for the other categories. This is not shown by the data - only report the data, don't infer.
All the best,
David
