[{"text": "Recently, significant problems regarding energy use have emerged. Enormous amounts of pollutants are being emitted from power plants, factories, and automobiles, which are worsening the condition of the earth. This environmental degradation is a clear result of acid rain, increased levels of carbon dioxide in the atmosphere, and other forms of air pollution. Acid rain and air pollution, for instance, are devastating forests, crops, and lakes over wide areas all over the world. Since the 1950s, carbon dioxide levels in the atmosphere have increased by 13%, setting the stage for global warming. As atmospheric temperature rise, grain output may significantly decrease, making it more difficult for farmers to keep pace with the growth of population. In urban areas, air pollution is taking a toll on the buildings and human health. To reduce the amount of environmental damage in cities, developed countries have devised technology to control the harmful emissions. However, as these countries already have an abundance of vehicles that continue to grow in number, the efficacy of these measures is diminished. Since cars and other vehicles create more air pollution than any other human activity, the most effective means to reduce pollution is to decrease the number of vehicles. A major shift away from automobile usage in urban areas may be possible with the aid of urban planning.", "type": "text_block", "database_type": "", "university": "", "year": "", "unit": "", "shift": "", "subject": "", "chapter": "", "topic": ""}, {"question": "", "options": [{"option": "the role of pollutants is increasing air pollution all over the world.", "answer": false}, {"option": "hazardous effects of air pollution and the role of urban planners in improving living conditions.\u00a0", "answer": true}, {"option": "the devastating effect of acid rain of forest resources, crops and water bodies", "answer": false}, {"option": "the extensive use of cars and vehicles is diminishing the growth of a risk-free society.\u00a0", "answer": false}], "type": "question", "database_type": "qb", "university": "du", "year": "2014-15", "unit": "a", "shift": "", "subject": "e-b", "chapter": "e-40", "topic": "", "title": "The passage is about :", "full_question": "The word 'pollutants' in the passage is a/an", "mark": 1.0, "answer": "one", "explanation": "The word 'pollutants' in the passage is a/an[E-31, DU-A : 2014-15]"}, {"question": "", "options": [{"option": "being expensive\u00a0", "answer": false}, {"option": "casusing a barrier", "answer": false}, {"option": "causing damage", "answer": true}, {"option": "\u00a0ringing a bell", "answer": false}], "type": "question", "database_type": "qb", "university": "du", "year": "2014-15", "unit": "a", "shift": "", "subject": "e-b", "chapter": "e-40", "topic": "", "title": "\" taking a toll \" in the passage means :", "full_question": "What happens with the increase in the atmospheric temperature?\u00a0", "mark": 1.0, "answer": "one", "explanation": "What happens with the increase in the atmospheric temperature?\u00a0[E-31, DU-A : 2014-15]"}]
