MCQ-> Read the following passage carefully and answer the questions given below it . Certain words have been printed in bold to help you locate them while answering some of the question.There was a girl who sang beautifully at the temple every morning. The music master used to happily recall, “One day when I went into the woods to pluck flowers, I found this baby under a pipal tree”. He picked her up carefully, raised her lovingly as if she were his daughter and taught her to sing before she spoke her first word. The music master grew old and didn’t see too well. The girl tended to him caringly. Many people including young men travelled from far and wide to hear her sing . This made the music master’s heart quake with fear. “You will choose one of them as your husband. What is to become of me ?” The girl replied ,”I shall not be apart from you “. But on a full moon night during the harvest festival, the master’s chief disciple touched his feet reverently and said, “Master, grant me your permission for your daughter has agreed to many me.” The master’s tears flowed freely,” She has chosen well. Go and fetch her let me hear you sing the first of many melodies that you will sing together.” The two began to sing in harmony. But the song was interrupted by the arrival of the royal messenger. “Your daughter is very fortunate– the king has sent for her,” the messenger said. At the palace the queen summoned the girl to her and said, “I place upon you the honour of making sure my daughter is never unhappy at her husband’s home.” There wasn’t a single tear in the girl’s eyes but she thought of the master and her heart was heavy.That very night the princess began her journey to Kambhoj. The princess’s royal chariotled the procession and the girl’s palanquin followed close behind carrying trunks of silk, jewellery and precious stones. It was covered with a velvet sheet and had soldiers on the both sides. As the procession passed, the master and his disciple Kumarsen stood still by wayside. A collective sigh escaped the crowd gathered there wishing that the princess wouldn’t feel homesick in her faraway home.Which of the following can be said about the girl? (A) She was brought up by her father as her mother had died when she was a baby. (B) She was a talented singer who had learnt to sing at an early age. (C) She was only allowed to sing with the master’s permission.....

MCQ-> Recently I spent several hours sitting under a tree in my garden with the social anthropologist William Ury, a Harvard University professor who specializes in the art of negotiation and wrote the bestselling book, Getting to Yes. He captivated me with his theory that tribalism protects people from their fear of rapid change. He explained that the pillars of tribalism that humans rely on for security would always counter any significant cultural or social change. In this way, he said, change is never allowed to happen too fast. Technology, for example, is a pillar of society. Ury believes that every time technology moves in a new or radical direction, another pillar such as religion or nationalism will grow stronger in effect, the traditional and familiar will assume greater importance to compensate for the new and untested. In this manner, human tribes avoid rapid change that leaves people insecure and frightened.But we have all heard that nothing is as permanent as change. Nothing is guaranteed. Pithy expressions, to be sure, but no more than cliches. As Ury says, people don’t live that way from day-to-day. On the contrary, they actively seek certainty and stability. They want to know they will be safe.Even so we scare ourselves constantly with the idea of change. An IBM CEO once said: ‘We only re-structure for a good reason, and if we haven’t re-structured in a while, that’s a good reason.’ We are scared that competitors, technology and the consumer will put us Out of business — so we have to change all the time just to stay alive. But if we asked our fathers and grandfathers, would they have said that they lived in a period of little change? Structure may not have changed much. It may just be the speed with which we do things.Change is over-rated, anyway, consider the automobile. It’s an especially valuable example, because the auto industry has spent tens of billions of dollars on research and product development in the last 100 years. Henry Ford’s first car had a metal chassis with an internal combustion, gasoline-powered engine, four wheels with rubber types, a foot operated clutch assembly and brake system, a steering wheel, and four seats, and it could safely do 1 8 miles per hour. A hundred years and tens of thousands of research hours later, we drive cars with a metal chassis with an internal combustion, gasoline-powered engine, four wheels with rubber tyres a foot operated clutch assembly and brake system, a steering wheel, four seats – and the average speed in London in 2001 was 17.5 miles per hour!That’s not a hell of a lot of return for the money. Ford evidently doesn’t have much to teach us about change. The fact that they’re still manufacturing cars is not proof that Ford Motor Co. is a sound organization, just proof that it takes very large companies to make cars in great quantities — making for an almost impregnable entry barrier.Fifty years after the development of the jet engine, planes are also little changed. They’ve grown bigger, wider and can carry more people. But those are incremental, largely cosmetic changes.Taken together, this lack of real change has come to man that in travel — whether driving or flying — time and technology have not combined to make things much better. The safety and design have of course accompanied the times and the new volume of cars and flights, but nothing of any significance has changed in the basic assumptions of the final product.At the same time, moving around in cars or aero-planes becomes less and less efficient all the time Not only has there been no great change, but also both forms of transport have deteriorated as more people clamour to use them. The same is true for telephones, which took over hundred years to become mobile or photographic film, which also required an entire century to change.The only explanation for this is anthropological. Once established in calcified organizations, humans do two things: sabotage changes that might render people dispensable, and ensure industry-wide emulation. In the 960s, German auto companies developed plans to scrap the entire combustion engine for an electrical design. (The same existed in the 1970s in Japan, and in the 1980s in France.) So for 40 years we might have been free of the wasteful and ludicrous dependence on fossil fuels. Why didn’t it go anywhere? Because auto executives understood pistons and carburettors, and would be loath to cannibalize their expertise, along with most of their factoriesAccording to the above passage, which of the following statements is true?
