प्रश्न
Read the following passage carefully and answer the following questions.
Pollution is the introduction of contaminants into the environment that cause harm to the ecosystem. The different kinds of pollution are air pollution, water pollution and land pollution. The release of various gases, finely divided solid particles, or liquid droplets that escape into the atmosphere to disperse and dilute in the environment is called air pollution. Modern society is also concerned about specific types of pollutants, such as noise pollution, light pollution, and plastic pollution.
Particulate Matter (PM), also known as particle pollution, is a complex mixture of extremely small particles and liquid droplets that get into the air. These particles if inhaled can affect health. The impact of PM 2.5 is particularly high in South Asia. Outdoor pollution is caused by a variety of pollutants like public and private vehicles, waste burning in the open, power production industries and construction and even cigarette smoking in public places.
Presently, air pollution is a major and growing risk factor for ill health in India. Delhi is one of the most air polluted cities in India. The air in the city as well as areas surrounding it has worsened to extremely hazardous levels in the recent years. This year’s pollution level is the worst in four years. Several studies have shown that poor air quality is a cause for many health issues among people with lower respiratory disorders with symptoms like dry cough, breathlessness, wheezing, chest discomfort, serious lung infections and cardio vascular diseases. Some studies throw light on the fact that about 16 per cent of the deaths worldwide in 2015 were due to pollution.
Air Masks are an option to protect oneself outdoor. Air masks can be used while commuting or while one is exposed to a polluted area. Some of these masks also include a layer of Activated carbon to filter the air. They protect us from suspended air particles and particulate matter up to the size of 2.5 microns and above. Their usage is limited to some days and should be disposed off after their prescribed duration of usage. The price for air masks starts from Rs 100 and can go up to Rs 500 and more.
We have to take active measures to control pollution and protect ourselves to lead a healthy and pollution free life.

(iv) Elephants lived a wary life …………………….. .
On the left bank of the Ganga, where it emerges from the Himalayan foothills, there is a long stretch of heavy forest. There are villages on the fringe of the forest, inhabited by bamboo cutters and farmers, but there are few signs of commerce or pilgrimage. Hunters, however, have found the area an ideal hunting ground during the last seventy years, and as a result, the animals are not as numerous as they used to be. The trees, too, have been disappearing slowly; and, as the forest recedes, the animals lose their food and shelter and move further on into the foothills. Slowly, they are being denied the right to live
Only the elephants can cross the river. And two years ago, when a large area of the forest was cleared to make way for a refugee resettlement camp, a herd of elephants - finding their favourite food, the green shoots of the bamboo, in short supply - waded across the river. They crashed through the suburbs of Haridwar, knocked down a factory wall, pulled down several tin roofs, held up a train, and left a trail of devastation in their wake until they found a new home in a new forest which was still untouched. Here, they settled down to a new life but an unsettled, wary life. They did not know when men would appear again, with tractors,bulldozers and dynamite.
