VIII. Choose the correct answer for each gap to complete the following passage. (2pts)

There are three main kinds of pollution – air pollution, water pollution, and

noise pollution. Air, which is the most important element of our environment

for our survival, can be polluted in many ways. Smoke in the air from mills,

factories, and industry contains carbon monoxide, carbon dioxide, and

methane, which are all poisonous gases. This leads to health problems like

asthma and lung diseases, and the thinning of the ozone layer, which

protects us from harmful UV rays. China, the USA, Russia, India, Mexico, and

Japan are the world leaders in air pollution emissions. Water is also polluted

by the discharge of commercial and industrial waste into surface water.

Sewage in drinking water is another cause of water pollution as it contains

germs and viruses. The noise of vehicles, mills, and factories can be really

unbearable. This kind of constant sound also causes headaches, tension,

mental stress, and migraines. People living next to a building site where

there is too much noise can become sick, as they cannot sleep or relax. This

is called noise pollution.
