- [{"text": "Increased numbers of women in science can only be a good thing. Not simply because it is grossly unjust for women to be unable to experience the challenging but also hugely intellectually rewarding experience of participating in scientific research, but also because the cost to society of excluding women is intoleraby high. We need the very best minds going into science, and it stands to reason that if women are excluded, we cut this resource in half. What's more, women bring new ways of thinking and a broader range of ideas to the table, which is crucial for science to flourish.All scientists have a responsibility to be feminists and encourage women to participate in science and fight the barriers that exist. However, this is often more easily said than done. There are several proposed reasons for why women are discouraged from participating in science at a range of levels - form primary school children to professors. Among other things, these include a lack of role models and support networks - as well as harassment and bullying - but also less obvious barriers, for example, unconscious biases in job interviews and letters of reference. In the end, the way to tackle prejudice against women is to increase awareness of the particular challenges faced by female scientists and to put systems in place that promote equal opportunities. Meanwhile, we need outstanding female role models to show unequivocally that women can compete on the sameintellectual level as men and encourage other women to follow their lead. Together we can create the level playing field which is so desperately required.", "type": "text_block", "database_type": "", "university": "", "year": "", "unit": "", "shift": "", "subject": "", "chapter": "", "topic": ""}, {"question": "", "options": [{"option": "Participation of women in science is beneficial for humanity.", "answer": false}, {"option": "Women bring in new ideas and resources.", "answer": false}, {"option": "Women tend to be more intelligent than men.", "answer": true}, {"option": "Excluding women from science is counter-productive.", "answer": false}], "type": "question", "database_type": "qb", "university": "du", "year": "2013-14", "unit": "a", "shift": "", "subject": "e-b", "chapter": "e-40", "topic": "", "title": "Which of the following opinions is not shared by the writer of the passage?", "full_question": "If an idea \"stands to reason\", it is-", "mark": 1.0, "answer": "one", "explanation": "If an idea \"stands to reason\", it is-[E-40, DU-A : 2013-14]"}, {"question": "", "options": [{"option": "lack of role models", "answer": false}, {"option": "inadequate facilities", "answer": false}, {"option": "orthodox mindset", "answer": true}, {"option": "character trait", "answer": false}], "type": "question", "database_type": "qb", "university": "du", "year": "2013-14", "unit": "a", "shift": "", "subject": "e-b", "chapter": "e-40", "topic": "", "title": "Which of the following is not the reason for women staying away from science, according to the passage?", "full_question": "\"Unequivocally\" means-", "mark": 1.0, "answer": "one", "explanation": "\"Unequivocally\" means-
- Quantum computing, a rapidly emerging technology, harnesses the properties of quantum mechanics to store data and perform calculations using qubits rather than regular binary bits. Quantum algorithms take a new approach to numerous sorts of complex problems by creating multidimensional spaces linking data points. Our classical computers, even super computers can't do this. Quantum computers might contribute greatly to security, finance, aeronautics, bioinformatics, digital manufacturing etc. Real quantum hardware, a tool scientists only began to imagine three decades ago, is now available to millions of developers. Powerful super conducting quantum processors are driving towards such a computing speed and capacity that they can potentially change the world.Quantum computing is _________ technology.
