MCQ-> The teaching and transmission of North Indian classical music is, and long has been, achieved by largely oral means. The raga and its structure, the often breathtaking intricacies of talc, or rhythm, and the incarnation of raga and tala as bandish or composition, are passed thus, between guru and shishya by word of mouth and direct demonstration, with no printed sheet of notated music, as it were, acting as a go-between. Saussure’s conception of language as a communication between addresser and addressee is given, in this model, a further instance, and a new, exotic complexity and glamour.These days, especially with the middle class having entered the domain of classical music and playing not a small part ensuring the continuation of this ancient tradition, the tape recorder serves as a handy technological slave and preserves, from oblivion, the vanishing, elusive moment of oral transmission. Hoary gurus, too, have seen the advantage of this device, and increasingly use it as an aid to instructing their pupils; in place of the shawls and other traditional objects that used to pass from shishya to guru in the past, as a token of the regard of the former for the latter, it is not unusual, today, to see cassettes changing hands.Part of my education in North Indian classical music was conducted via this rather ugly but beneficial rectangle of plastic, which I carried with me to England when I was a undergraduate. Once cassette had stored in it various talas played upon the tabla, at various tempos, by my music teacher’s brother-in law, Hazarilalii, who was a teacher of Kathak dance, as well as a singer and a tabla player. This was a work of great patience and prescience, a one-and-a-half hour performance without my immediate point or purpose, but intended for some delayed future moment who I’d practise the talas solitarily.This repeated playing our of the rhythmic cycles on the tabla was inflected by the noises-an hate auto driver blowing a horn; the sound bf overbearing pigeons that were such a nuisance on the banister; even the cry of a kulfi seller in summer —entering from the balcony of the third foot flat we occupied in those days, in a lane in a Bombay suburb, before we left the city for good. These sounds, in turn, would invade, hesitantly, the ebb and flow of silence inside the artificially heated room, in a borough of West London, in which I used to live as an undergraduate. There, in the trapped dust, silence and heat, the theka of the tabla, qualified by the imminent but intermittent presence of the Bombay subrub, would come to life again. A few years later, the tabla and, in the background, the pigeons and the itinerant kulfi seller, would inhabit a small graduate room in Oxford.cThe tape recorder, though, remains an extension of the oral transmission of music, rather than a replacement of it. And the oral transmission of North Indian classical music remains, almost uniquely, testament to the fact that the human brain can absorb, remember and reproduces structures of great complexity and sophistication without the help of the hieroglyph or written mark or a system of notation. I remember my surprise on discovering the Hazarilalji- who had mastered Kathak dance, tala and North Indian classical music, and who used to narrate to me, occasionally, compositions meant for dance that were grant and intricate in their verbal prosody, architecture and rhythmic complexity- was near illustrate and had barely learnt to write his name in large and clumsy letters.Of course, attempts have been made, throughout the 20th century, to formally codify and even notate this music, and institutions set up and degrees created, specifically to educate students in this “scientific” and codified manner. Paradoxically, however, this style of teaching has produced no noteworthy student or performer; the most creative musicians still emerge from the guru-shishya relationship, their understanding of music developed by oral communication.The fact that North Indian classical music emanates from, and has evolved through, oral culture, means that this music has a significantly different aesthetic, aw that this aesthetic has a different politics, from that of Western classical music) A piece of music in the Western tradition, at least in its most characteristic and popular conception, originates in its composer, and the connection between the two, between composer and the piece of music, is relatively unambiguous precisely because the composer writes down, in notation, his composition, as a poet might write down and publish his poem. However far the printed sheet of notated music might travel thus from the composer, it still remains his property; and the notion of property remains at the heart of the Western conception of “genius”, which derives from the Latin gignere or ‘to beget’.The genius in Western classical music is, then, the originator, begetter and owner of his work the printed, notated sheet testifying to his authority over his product and his power, not only of expression or imagination, but of origination. The conductor is a custodian and guardian of this property. IS it an accident that Mandelstam, in his notebooks, compares — celebratorily—the conductor’s baton to a policeman’s, saying all the music of the orchestra lies mute within it, waiting for its first movement to release it into the auditorium?The raga — transmitted through oral means — is, in a sense, no one’s property; it is not easy to pin down its source, or to know exactly where its provenance or origin lies. Unlike the Western classical tradition, where the composer begets his piece, notates it and stamps it with his ownership and remains, in effect, larger than, or the father of, his work, in the North India classical tradition, the raga — unconfined to a single incarnation, composer or performer — remains necessarily greater than the artiste who invokes it.This leads to a very different politics of interpretation and valuation, to an aesthetic that privileges the evanescent moment of performance and invocation over the controlling authority of genius and the permanent record. It is a tradition, thus, that would appear to value the performer, as medium, more highly than the composer who presumes to originate what, effectively, cannot be originated in a single person — because the raga is the inheritance of a culture.The author’s contention that the notion of property lies at the heart of the Western conception of genius is best indicated by which one of the following?

MCQ-> India is rushing headlong toward economic success and modernisation, counting on high- tech industries such as information technology and biotechnology to propel the nation toprosperity. India’s recent announcement that it would no longer produce unlicensed inexpensive generic pharmaceuticals bowed to the realities of the World TradeOrganisation while at the same time challenging the domestic drug industry to compete with the multinational firms. Unfortunately, its weak higher education sector constitutes the Achilles’ Heel of this strategy. Its systematic disinvestment in higher education inrecent years has yielded neither world-class research nor very many highly trained scholars, scientists, or managers to sustain high-tech development. India’s main competitors especially China but also Singapore, Taiwan, and South Korea — are investing in large and differentiated higher education systems. They are providingaccess to large number of students at the bottom of the academic system while at the same time building some research-based universities that are able to compete with theworld’s best institutions. The recent London Times Higher Education Supplement ranking of the world’s top 200 universities included three in China, three in Hong Kong,three in South Korea, one in Taiwan, and one in India (an Indian Institute of Technology at number 41.— the specific campus was not specified). These countries are positioningthemselves for leadership in the knowledge-based economies of the coming era. There was a time when countries could achieve economic success with cheap labour andlow-tech manufacturing. Low wages still help, but contemporary large-scale development requires a sophisticated and at least partly knowledge-based economy.India has chosen that path, but will find a major stumbling block in its university system. India has significant advantages in the 21st century knowledge race. It has a large high ereducation sector — the third largest in the world in student numbers, after China andthe United States. It uses English as a primary language of higher education and research. It has a long academic tradition. Academic freedom is respected. There are asmall number of high quality institutions, departments, and centres that can form the basis of quality sector in higher education. The fact that the States, rather than the Central Government, exercise major responsibility for higher education creates a rather cumbersome structure, but the system allows for a variety of policies and approaches. Yet the weaknesses far outweigh the strengths. India educates approximately 10 per cent of its young people in higher education compared with more than half in the major industrialised countries and 15 per cent in China. Almost all of the world’s academic systems resemble a pyramid, with a small high quality tier at the top and a massive sector at the bottom. India has a tiny top tier. None of its universities occupies a solid position at the top. A few of the best universities have some excellent departments and centres, and there is a small number of outstanding undergraduate colleges. The University Grants Commission’s recent major support of five universities to build on their recognised strength is a step toward recognising a differentiated academic system and fostering excellence. At present, the world-class institutions are mainly limited to the Indian Institutes of Technology (IITs), the Indian Institutes of Management (IIMs) and perhaps a few others such as the All India Institute of Medical Sciences and the Tata Institute of Fundamental Research. These institutions, combined, enroll well under 1 percent of the student population. India’s colleges and universities, with just a few exceptions, have become large, under-funded, ungovernable institutions. At many of them, politics has intruded into campus life, influencing academic appointments and decisions across levels. Under-investment in libraries, information technology, laboratories, and classrooms makes it very difficult to provide top-quality instruction or engage in cutting-edge research.The rise in the number of part-time teachers and the freeze on new full-time appointments in many places have affected morale in the academic profession. The lackof accountability means that teaching and research performance is seldom measured. The system provides few incentives to perform. Bureaucratic inertia hampers change.Student unrest and occasional faculty agitation disrupt operations. Nevertheless, with a semblance of normality, faculty administrators are. able to provide teaching, coordinate examinations, and award degrees. Even the small top tier of higher education faces serious problems. Many IIT graduates,well trained in technology, have chosen not to contribute their skills to the burgeoning technology sector in India. Perhaps half leave the country immediately upon graduation to pursue advanced study abroad — and most do not return. A stunning 86 per cent of students in science and technology fields from India who obtain degrees in the United States do not return home immediately following their study. Another significant group, of about 30 per cent, decides to earn MBAs in India because local salaries are higher.—and are lost to science and technology.A corps of dedicated and able teachers work at the IlTs and IIMs, but the lure of jobs abroad and in the private sector make it increasingly difficult to lure the best and brightest to the academic profession.Few in India are thinking creatively about higher education. There is no field of higher education research. Those in government as well as academic leaders seem content to do the “same old thing.” Academic institutions and systems have become large and complex. They need good data, careful analysis, and creative ideas. In China, more than two-dozen higher education research centers, and several government agencies are involved in higher education policy.India has survived with an increasingly mediocre higher education system for decades.Now as India strives to compete in a globalized economy in areas that require highly trained professionals, the quality of higher education becomes increasingly important.India cannot build internationally recognized research-oriented universities overnight,but the country has the key elements in place to begin and sustain the process. India will need to create a dozen or more universities that can compete internationally to fully participate in the new world economy. Without these universities, India is destined to remain a scientific backwater.Which of the following ‘statement(s) is/are correct in the context of the given passage ? I. India has the third largest higher education sector in the world in student numbers. II. India is moving rapidly toward economic success and modernisation through high tech industries such as information technology and bitechonology to make the nation to prosperity. III. India’s systematic disinvestment in higher education in recent years has yielded world class research and many world class trained scholars, scientists to sustain high-tech development.....

MCQ-> In the annals of investing, Warren Buffett stands alone. Starting from scratch, simply by picking stocks and companies for investment, Buffett amassed one of the epochal fortunes of the twentieth century. Over a period of four decades more than enough to iron out the effects of fortuitous rolls of the dice, Buffett outperformed the stock market, by a stunning margin and without taking undue risks or suffering a single losing year. Buffett did this in markets bullish and bearish and through economies fat and lean, from the Eisenhower years to Bill Clinton, from the l950s to the l990s, from saddle shoes and Vietnam to junk bonds and the information age. Over the broad sweep of postwar America, as the major stock averages advanced by 11 percent or so a year, Buffett racked up a compounded annual gain of 29.2 percent. The uniqueness of this achievement is more significant in that it was the fruit of old-fashioned, long-term investing. Wall Street’s modern financiers got rich by exploiting their control of the public's money: their essential trick was to take in and sell out the public at opportune moments. Buffett shunned this game, as well as the more venal excesses for which Wall Street is deservedly famous. In effect, he rediscovered the art of pure capitalism, a cold-blooded sport, but a fair one. Buffett began his career, working out his study in Omaha in 1956. His grasp of simple verities gave rise to a drama that would recur throughout his life. Long before those pilgrimages to Omaha, long before Buffett had a record, he would stand in a comer at college parties, baby-faced and bright-eyed, holding forth on the universe as a dozen or two of his older, drunken fraternity brothers crowded around. A few years later, when these friends had metamorphosed into young associates starting out on Wall Street, the ritual was the same. Buffett, the youngest of the group, would plop himself in a big, broad club chair and expound on finance while the others sat at his feet. On Wall Street, his homespun manner made him a cult figure. Where finance was so forbiddingly complex, Buffett could explain it like a general-store clerk discussing the weather. He never forgot that underneath each stock and bond, no matter how arcane, there lay a tangible, ordinary business. Beneath the jargon of Wall Street, he seemed to unearth a street from small-town America. In such a complex age, what was stunning about Buffett was his applicability. Most of what Buffett did was imitable by the average person (this is why the multitudes flocked to Omaha). It is curious irony that as more Americans acquired an interest in investing, Wall Street became more complex and more forbidding than ever. Buffett was born in the midst of depression. The depression cast a long shadow on Americans, but the post war prosperity eclipsed it. Unlike the modern portfolio manager, whose mind- set is that of a trader, Buffett risked his capital on the long term growth of a few select businesses. In this, he resembled the magnates of a previous age, such as J P Morgan Sr.As Jack Newfield wrote of Robert Kennedy, Buffett was not a hero, only a hope; not a myth, only a man. Despite his broad wit, he was strangely stunted. When he went to Paris, his only reaction was that he had no interest in sight-seeing and that the food was better in Omaha. His talent sprang from his unrivaled independence of mind and ability to focus on his work and shut out the world, yet those same qualities exacted a toll. Once, when Buffett was visiting the publisher Katharine Graham on Martha’s Vineyard, a friend remarked on the beauty of the sunset. Buffett replied that he hadn't focused on it, as though it were necessary for him to exert a deliberate act of concentration to "focus" on a sunset. Even at his California beachfront vacation home, Buffett would work every day for weeks and not go near the water. Like other prodigies, he paid a price. Having been raised in a home with more than its share of demons, he lived within an emotional fortress. The few people who shared his office had no knowledge of the inner man, even after decades. Even his children could scarcely recall a time when he broke through his surface calm and showed some feeling. Though part of him is a showman or preacher, he is essentially a private person. Peter Lynch, the mutual-fund wizard, visited Buffett in the 1980s and was struck by the tranquility in his inner sanctum. His archives, neatly alphabetized in metal filing cabinets, looked as files had in another era. He had no armies of traders, no rows of electronic screens, as Lynch did. Buffett had no price charts, no computer - only a newspaper clipping from 1929 and an antique ticker under a glass dome. The two of them paced the floor, recounting their storied histories, what they had bought, what they had sold. Where Lynch had kicked out his losers every few weeks, Buffett had owned mostly the same few stocks for years and years. Lynch felt a pang, as though he had traveled back in time. Buffett’s one concession to modernity is a private jet. Otherwise, he derives little pleasure from spending his fabulous wealth. He has no art collection or snazzy car, and he has never lost his taste for hamburgers. He lives in a commonplace house on a tree-lined block, on the same street where he works. His consuming passion - and pleasure - is his work, or, as he calls it, his canvas. It is there that he revealed the secrets of his trade, and left a self-portrait.“Saddle shoes and Vietnam”, as expressed in the passage, refers to: I. Denier cri and Vietnam war II. Growth of leather footwear industry and Vietnam shoe controversy III. Modern U.S. population and traditional expatriates IV. Industrial revolution and Vietnam Olympics V. Fashion and Politics....
