VII. Read the following passage and then answer the questions below it.
Air pollution is a cause of ill-health in human beings. In a lot of countries there are laws 
limiting the amount of smoke which factories can produ ce. Although there isn‟t enough 
information on the effects of smoke in the atmosphere, doctors have proved th at air pollution 
causes lung diseases.
The gases from the exhausts of cars have also increased air pollution in most cities. The lead in 
petrol produces a poisonous gas which often collects in busy streets surrounded by high buildings. 
Children who live in areas where there is a lot of lead in the atmosphere cannot think as quickly as 
other children and they are clumsy when they use their hands.
There are other long-term effects of pollution. If the gases in the atmosphere continue to 
increase, the earth’s climate may become warmer. A lot of the ice near the Poles may melt and may 
cause serious floods.
