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.

Read the passage given below and answer the questions that follow:
The term dietary fibres refers collectively to indigestible carbohydrates present in plant foods. The importance of these dietary fibres came into the picture when it was observed that the people having diet rich in these fibres, had low incidence of coronary heart disease, irritable bowel syndrome, dental caries and gall stones.
The foodstuffs rich in these dietary fibres are cereals and grains, legumes, fruits with seeds, citrus fruits, carrots, cabbage, green leafy vegetables, apples, melons, peaches, pears etc.
These dietary fibres are not digested by the enzymes of the stomach and the small intestine whereas most of other carbohydrates like starch and sugar are digested and absorbed. The dietary fibres have the property of holding water and because of it, these get swollen and behave like a sponge as these pass through the gastrointestinal tract. The fibres add bulk to the diet and increase transit time in the gut. Some of these fibres may undergo fermentation in the colon.
In recent years, it has been considered essential to have some amount of fibres in the diet. Their beneficial effects lie in preventing coronary heart disease, and decreasing cholesterol level. The fibres like gums and pectin are reported to decrease postprandial (after meals) glucose level in blood. These types of dietary fibres are recommended for the management of certain types of diabetes. Recent studies have shown that the fenugreek (Methi) seeds, which contain 40 per cent gum, are effective in decreasing blood glucose and cholesterol levels as compared to other gum containing vegetables.
Some dietary fibres increase transit time and decrease the time of release of ingested food in colon. The diet having less fibres is associated with colon cancer and the dietary fibres may play a role in decreasing the risk of it.
The dietary fibres hold water so that stools are soft, bulky and readily eliminated. Therefore high fibre intake prevents or relieves constipation.
The fibres increase motility of the small intestine and the colon and by decreasing the transit time there is less time for exposure of the mucosa to harmful toxic substances. Therefore, there is a less desire to eat and the energy intake can be maintained within the range of requirement. This phenomenon helps in keeping a check on obesity. Another reason in helping to decrease obesity is that the high-fibre diets have somewhat lower coefficients of digestibility.
The dietary fibres may have some adverse effects on nutrition by binding some trace metals like calcium, magnesium, phosphorus, zinc and others and therefore preventing their proper absorption. This may pose a possibility of nutritional deficiency especially when diets contain marginal levels of mineral elements. This may become important constraints on increasing dietary fibres. It is suggested that an intake of 40 grams dietary fibres per day is desirable.

The Stationmaster’s Supreme Sacrifice by Sanchari Pal (Adapted)
- Thirty-three years ago, on the night of December 2, 1984, Bhopal was hit by a catastrophe that had no parallel in the world’s industrial history. An accident at the Union Carbide pesticide plant in Bhopal had released almost 30 tons of a highly toxic gas called methyl isocyanate, turning the city into a vast gas chamber. The result was a nightmare; more than 600,000 people were exposed to the deadly gas cloud that left thousands dead and many more breathless, blind and in agonizing pain. Few people know that during the Bhopal gas tragedy a heroic stationmaster risked his own life to save others.
- On the evening of December 3, 1984, Ghulam Dastagir was settling down in his office to complete some pending paperwork. This work kept him in his office till 1am in the night, when he emerged to check the arrival of the Gorakhpur Mumbai Express. As he stepped on to the platform, the deputy stationmaster felt his eyes burn and a queer itching sensation in his throat. He did not know that poisonous fumes leaking from Union Carbide’s pesticide factory were stealthily enveloping the railway station.
- Beginning to choke, Dastagir did not know then that twenty-three of his railway colleagues, including his boss, station superintendent Harish Dhurve, had already died. It was later reported that Dhurve had heard about the deadly gas and had immediately tried stopping the movement of trains passing through Bhopal before collapsing in his office chamber. His suddenly worsening health and years of experience told Dastagir that something was very wrong. Though he did not fully comprehend what was happening, he decided to act immediately when he did not get any response from the station master. He alerted the senior staff at nearby stations, like Vidisha and Itarsi, to suspend all train traffic to Bhopal.
- However, the jam-packed GorakhpurKanpur Express was already standing at the platform and its departure time was 20 minutes away. Listening to his gut instinct, Dastagir summoned his staff and told them to immediately clear the train for departure. When they asked if they should wait until the order to do so came from the head office, Dastagir replied that he would take complete responsibility for the train’s early departure. He wanted to ensure that the train left immediately, without any delay. His colleagues later recalled that Dastagir could barely stand and breathe as he spoke to them. Breaking all rules and without taking permission from anyone, he and his brave staff personally flagged off the train.
- But Dastagir’s work was not done. The railway station was filling up with people, desperate to flee the fumes. Some were gasping, others were vomiting, and most were weeping. Dastagir chose to remain on duty, running from one platform to another, attending, helping and consoling victims. He also sent an SOS to all the nearby railway offices, asking for immediate medical help. As a result, four ambulances with paramedics and railway doctors arrived at the station. It was winter and the gas was staying low to the ground, a thick haze poisoning everything in its path. Besieged by hordes of suffering people, the station soon resembled the emergency room of a large hospital. Dastagir stayed at the station, steadfastly doing his duty, knowing that his family was out there in the ill-fated city. That day all he had for his protection was a wet handkerchief on his mouth.
- Ghulam Dastagir’s devotion to duty saved the lives of hundreds of people. However, the catastrophe didn’t leave him unscathed. One of his sons died on the night of the tragedy and another developed a lifelong skin infection. Dastagir himself spent his last 19 years shuttling in and out of hospitals; he developed a painful growth in the throat due to prolonged exposure to toxic fumes. When he passed away in 2003, his death certificate mentioned that he was suffering from diseases caused as a direct result of exposure to MIC (Methyl Isocyanate) gas. A memorial has been built at platform No.1 to pay tribute to those who sacrificed their lives in the line of duty on the fateful night of December 3, 1984. However, Ghulam Dastagir, who died later, is not one of them. A forgotten hero whose sense of duty and commitment saved countless lives, Dastagir’s story deserves to be recognized and remembered by our fellow countrymen.
