cities. Everybody's health is getting threatened by these fatal substances. For the reduction of 
their amount, pro-environmental groups in the U.K have proposed ways of limiting the use of 
automobiles. One solution would be to make daily commuters use mass transportation vehicles 
such as .buses, trains or subways instead of their private cars. Another proposal by these groups 
is that car drivers be prevented from driving into the1 city centre one or two days a week. It is 
also proposed that people be banned from parking on certain streets. If car drivers were 
controlled in such ways by legal steps, people would be forced to make more use of mass 
transportation than private cars.

a) The air pollution is claimed to be mainly caused by hydrocarbon and carbon monoxide 
from automobiles. 
b) Mass transportation vehicles pollute the air we all breathe more than automobiles. 
c) While so much smoke comes out of factories, it would be unfair to place all the blame on 
mass transportation vehicles. 
d) If the use of cars remains uncontrolled, the concerned fatal substances will kill many people 
every day. 
11. To reduce the amount of fatal substances, groups in favour of the environment 
have..................... 
a) suggested that car driving in city centres should be completely banned. 
b) proposed that car drivers be prevented from driving into the city centre once or twice a week. 
c) proposed that some limitations be imposed on car owners driving into and out of the
