Writing task 1 The graph below shows the percentage of river water in the UK that is of good chemical quality, in the period between 1990 and 2002.

The given line chart compares data about the proportion of rivers that flowed in 4 various regions of the UK and had the best chemical quality from 1990 to 2002.

Overall

, it is important that the trend of Scotland and Northern Ireland

instead

of two other areas increased over the period of 12 years.

According to

the diagram, at the start, Wales, the main region where rivers had the best chemical quality in 1990, hit 95%;

then

its fraction stabilized until 1998;

however

, it reduced moderately to 80% in 2002;

In contrast

, the second one whose name was Northern Ireland reached the constant portion at roughly 85% between 1990 and 1998;

thereafter

, it rose slightly to 95% in 2000, and its percentage was constant until 2002. The graph demonstrates that in the beginning, England touched 45%;

then

it climbed significantly and hit the vertex at just under 70% in 1996, but it declined enormously and scored the minimum point at 30% in 1998;

although

, it jumped to nearly a half in 2002. The

last

district was Scotland;

moreover

, it hit just over one-fifth in 1990;

then

it increased to 30% and it was stable until 1996 after that, it leapt considerably and peaked at almost 60% in 2000;

nevertheless

, it fell to 40% in 2002.
