The graphs below show the size of the ozone hole over Antarctica and the 
production of three ozone-damaging gases from 1980 to 2000. Summarise the 
information by selecting and reporting the main features, and make comparisons 
where relevant. 
The given line graphs illustrate the changes in the Ozone hole size over the Antarctica region 
and the amount of three gases produced which caused damage to the ozone layer from 1980 
to 2000. 
The ozone hole was at its smallest size of about 400 thousand square kilometres in 1980, but 
20 years later, it grew drastically to 3.6 million square kilometres. It increased by nine times. 
The only period when there was a reduction in the size was in the early 1990s (from 2 to 1.2 
million square km). 
In 1980, about 70 million tonnes of CFC–11 was produced, which remained stable for 3 years 
before undergoing a steady decline to below 10 million tonnes in the late 1990s. The 
production of CFC–12, on the other hand, showed an upward trend throughout the 20-year 
period from 25 to 50 million tonnes, surpassing the production of CFC–11 in 1989. N
2
O, 
however, was not produced until 1990, but its production grew rapidly to about 40 million 
tonnes by the year 2000.
Overall, the two graphs indicate that it was mainly CFC–12 and N
2
O, which gave rise to the 
expansion of ozone hole over Antarctica in the last two decades of the 20
th
century.

The diagram below shows the plan of a library in 2001 and 2009. Summarise the 
information by selecting and reporting the main features and make comparisons 
where relevant.
The given diagram compares the map of the ground floor of a library in 2001 and 2009. It can 
be clearly seen that a lot of changes took place in the ground floor over a period of eight 
years.
In 2001, the self help and history section occupied the whole left wall, but in 2009 fiction, 
kitchen, economics and law sections were also added. The fiction section on the back wall of 
the ground floor, was replaced by the children’s books in front of which the children’s area 
was made. On the right wall the newspapers and periodicals area was there in 2001. 
However, in 2009, films and DVDs were placed in front of which computers were placed. 
The eight smaller tables in 2001 were removed and in place of these four bigger tables were 
placed.
No changes were made to the entrance, the librarian’s desk and the stairs. The librarian’s 
desk was right after the entrance and the stairs were in the front right corner in both the 
years.
Overall, a lot of additions can be seen in the ground floor of the library over a period of eight 
years.
