[{"text": "Read the passage and answer Q. (147-150)About fifty years ago, plant physiologists set out to grow roots, by themselves in solutions in laboratory flasks. The scientists found that the nutrition of isolated roots was quite simple. They required sugar and usual minerals and vitamins. However, they did not require organic nitrogen compounds. These roots got along fine on mineral inorganic nitrogen. Roots are capable of making their own protein and and other organ compounds.These activities require energy of course. The process of respiration uses sugar to make the high-energy compound ATP, \u00a0which drives the bio-chemical actions. Respiration also requires oxygen. Highly act roots require a good deal of oxygen.", "type": "text_block", "database_type": "", "university": "", "year": "", "unit": "", "shift": "", "subject": "", "chapter": "", "topic": ""}, {"question": "What is the main topic of the passage?", "mark": 1.0, "answer": "one", "explanation": "", "options": [{"option": "The relationship between a plant's roots and its shoots.", "answer": false}, {"option": "What can be learned by growing roots in isolation", "answer": true}, {"option": "How plants can be grown without roots", "answer": false}, {"option": "What elements are necessary for the growth of plants", "answer": false}], "type": "question", "database_type": "qb", "university": "du", "year": "2001-02", "unit": "a", "shift": "", "subject": "e-b", "chapter": "e-40", "topic": "", "title": "What is the main topic of the passage?", "full_question": "What is the main topic of the passage?
