Question

(A) Read the passage given below and answer the following questions: 1 x 5 = 5

In recent years, pollution has become one of the most serious problems we face in modern day life.

The rapid development in science, technology and industry has all contributed to this problem. On

the other hand, deforestation is another concern as the lack of trees can intensify this problem

because trees provide oxygen, which is fundamental for animal life. Air pollution is the result of

cars exhaust pumping carbon monoxide that poisons the air. The discharge from factories causes

much air pollution. However, radiation from nuclear weapon tests is an invisible form of air

pollution. Radioactive dust is invisible but deadly to all living beings. To solve this problem we

should consider using lead-free petrol in cars and keep badly maintained vehicles off the roads.

There should be strict control on factories and issue heavy fines for offenders. It would be

beneficial to move harmful industries outside city boundaries. On the other hand water pollution

happens when water supplies are contaminated by waste from factories. Factory waste leaks into

the rivers and kills millions of fish. Artificial fertilizers and pesticides flow into rivers and poison

the water. Modern farming methods are responsible for much of the water pollution. The sea is

polluted by oil, chemicals and other radioactive waste. To overcome this problem it should be

illegal to dispose waste into the sea and a lot of consideration should be made to develop a water

purification system. While, farmers should use safer fertilizers and pesticides in their farms.Questions:1. What has caused pollution recently?

2. What provides oxygen?

3. Which is an invisible kind of pollution?

4. How can we solve air pollution?

5. What contaminates water?

​

Answer 1

Answer:

1. MODERN TECHNOLOGY HAS RESULTED IN THIS

2. TREES PROVIDE OXYGEN TO US.

3. RADIOACTIVE DUST IS A TYPE OF INVISIBLE DUST

4. BY USING LEAD FREE PETROL AND REMOVE BAD MAINTAINED CARS

5. THE BAD OR CHEMICAL FERTILIZERS OIL SPILL IN SEAS AND OCEANS PESTICIDES GET MIXED WITH THE RAINWATER AND GETS WATERE CONTAMINATED.
