TOGETHER TOWARDS A SAFER INDIA (PART-II)
NCERT TEXTBOOK QUESTIONS WITH ANSWERS
1. Read the following two contrasting situations:
(a) Coastal Orissa is one of the most cyclone prone areas in India. On 29th October 1999, a Super Cyclone of speed exceeding 300 kmph lashed across the densely populated coastal districts of Orissa. Torrential rain persisted for more than two Lays. The storm surge with a height of almost 10 meters pushed its way more than 20 km inlands, submerging vast area, devasting everything in its path… people, cattle, homes, trees, electricity poles….
(b) The flag in the bright color signaling evacuation went up. Kabir was perched over a large mound of earth looking at his village. Slowly, the population was moving out, some carrying pink plastic bags and some with children and disabled people on their backs, being lead by Mir. the Early Warning and Evacuation Task Force Members (IFM). They would all be together again in the huge multi-purpose cyclone shelter till the cyclone alert is taken off. As the cattle was being herded to the mound (that created by the villagers last summer), with ropes to secure the animals, Kabir left to take a last look at the food, water and medical supplies in the shelter, that was pre-positioned a few days ago, after receiving the warning. This being the cyclone season…. He put his Shelter Management TFM badge on his arm as he picked up the activity kits for the children who always looked up to him for entertainment… It was 1991, Bangladesh, one of the most cyclone prone countries in the world, experienced a cyclone with wind speed reaching 250 km. per hour, killing around 1.40,000 people.
