MODEL TEST PAPER 2

Time : 2 hours (Based on Chapters - 9 to 16) M. Marks : 60

Reading

A. Read the given passage and answer the following questions.
The air that we breathe today is more polluted than it was before. More factories, more
vehicles, greater use of aerosols and sprays, increasing number of refrigerators and air
conditioners that release CFC gases, have all contributed towards pollution. When
certain chemicals from the smoke and fumes rise up into the air, they are mixed with the
water vapour in the clouds and make it acidic. When rain or snow falls from such
polluted clouds, it is also acidic in nature. This acidic rain falls on the leaves of trees, on
the fertile soil and also runs into lakes and rivers. The effects of this rain are disastrous.
Trees slowly lose their leaves and die. Fertile soil turns acidic and damages the plants and
crops. The fish and animals living in lakes or seas are killed. Even our drinking water can
get affected. Many forests, all over the world, have suffered severe damage on account of
acid rain. Before it is too late, we must try and put a stop to the millions of vehicles and
chimneys pouring harmful fumes into the air.
