A and B are athletes. A covers a distance of 1 km in 5 minutes and 50 seconds, while B covers the same distance in 6 minutes and 4 seconds. If both of them start together and run at uniform speed, approximately by what distance will A win a 5 km marathon.
  • a)
    220 m
  • b)
    247 m
  • c)
    192 m
  • d)
    157 m
Correct answer is option 'C'. Can you explain this answer?

Bali answered  •  3 minutes ago
A takes (350 x 5) seconds to cover a 5 km marathon.
In (60 x 6) + 4 = 364 seconds, B covers 1 km.
So, in (350 x 5) seconds, B would cover (350 x 5)/364 ~ 4.808
Thus, approximate distance by which A wins 5 km marathon = 5000 - 4807 = 192m
Hence, option 3.

There is a widespread myth that Hitler had a personal ambition to kill all the Jews in the world. Some go so far as to believe that Hitler's primary motivation in rising to leadership in Germany and starting World War II was to kill the Jews. This is not supported by any part of the historical record, which indicates instead that his overt political motivation was to avenge Germany's defeat in World War I, and that his covert personal motivation was probably to glorify himself.
The unspeakable pathos of the Holocaust was all too real... but it was not motivated by Hitler's personal feelings about Jews. Instead, the millions of innocent civilians including women and children who perished in horrifying death camps were the collateral damage of a war that had no mercy for any segment of humanity. The poor Jewish victims of the Holocaust had been left helpless because they lacked the protection of their own nation during an era of violent nationalism. The sickening extremities of Auschwitz, Bergen-Belsen and Treblinka are too massive to be blamed on any single perpetrator, and it's tragic to realize that most of the horror could have been avoided if nations like the United States of America had been willing to take in Jews as refugees during the many years that Nazi bureaucrats tried to arrange their deportation.
The Holocaust happened, but there is no historical basis at all for the idea that Hitler had ever had a master plan to slaughter Jews.
The Nazi movement's most active opposition during the period of Hitler's rise to power were the various German Communist parties, which also strove to overthrow the weak Weimar Republic. In the years after World War I in Europe, Jews were widely considered to be Communists, as indeed they often were. A coalition of Jewish and non-Jewish Communists had taken over Russia in the final year of World War I and fear of Jewish/Communist revolution was absolutely rampant all over Europe after the war was over. Most significantly, there had been an attempted German Communist revolution in 1919, led by two prominent and heroic German Jews, Rosa Luxembourg and Kurt Liebknecht.
Today when we think of European Jews, we think of Anne Frank or Schindler's list. But the fear of Communist revolution formed the entire context for the political meaning of the term "Jew" among the parties fighting for power in 1920s and 1930s Germany. Just as today in the United States of America the word "Muslim” is often used (unfairly) as a synonym for "terrorist", in Weimar Germany the word "Jew" was often used as a synonym for "Communist". This important but often forgotten fact explains a lot about the root causes of the Holocaust.

Kuldeep Singh answered  •  11 hours ago
Option 2 with just “Jews” is incorrect as the quoted text states “they often were” and not “all”.
Option 3 with “Christianity” is out of context.
Option 4 is incorrect with “Communist Revolution”. The quoted text only talks about being a Communist and not being part of the Communist Revolution.
Option 1 is appropriate with “most” and “Communists”. Hence, the correct answer is option 1.

Mumtaj answered  •  11 hours ago
The number of days between 31st December 1899 and 31st December 1903 = 365 x 4 = 1460
The number of days between 31st December 1903 and 21st April 1904 = 31 + 29 + 31+21 = 112
Total number of days = 1572 Dividing 1572 by 7 the remainder = 4
Hence, 21st April 1904 falls on Tuesday.
Hence, option 2.
We know that in a non-leap year there are 52 weeks and 1 odd day.
There is no leap year between 1899 to 1903. Hence, there are 4 odd days.
Number of odd days between 31st December 1903 and 21st April 1904 = 3 + 1 + 3 + 0 = 7
Thus, there are total 4 odd days between the given time frame. 21st April 1904 will be a Tuesday.Hence, 21st April 1904 falls on Tuesday.
Hence, option 2.
We know that in a non-leap year there are 52 weeks and 1 odd day.

The passage given below is followed by a set of questions. Choose the most appropriate answer to each question.
The computer is an artifact, not a natural phenomenon, and science is about natural phenomena. As a creation of the human mind, independent of the physical world, mathematics is not a science but a tool for doing science. Modern techno-science undercuts the first point. How does one distinguish between nature and artifact when we rely on artifacts to produce or afford access to the natural phenomena? In insisting that ‘Nature to be commanded must be obeyed,’ Francis Bacon placed nature and art on the same physical and epistemological level.
Artifacts work by the laws of nature, and by working to reveal those laws. Only with the development of thermodynamics, through the analysis of steam engines, did we ‘discover’ that world is a heat engine subject to the laws of entropy. Later came the information theory - the analysis of communications systems arising from the problems of long-distance telephony. Now, with the computer, nature has increasingly become a computation. DNA is code, the program for the process of development. Although the computational world may have begun as a metaphor, it is now acquiring the status of metaphysics, thus repeating the early modern transition from the metaphor of ‘machine of the world’ to the metaphysics of 'matter in motion'.
The artifact as conceptual scheme is deeply, indeed inseparably, embedded in nature, and the relationship works both ways, as computer scientists turn to biological models to address problems of stability, adaptability, and complexity. Embedded too is the mathematics that has played a central role in the articulation of many of these models of nature - thermodynamical, informational, and computational - not simply by quantifying them but also, and more importantly, by capturing their structure and even filling it out. Applied to the world as models, mathematical structures have captured its workings in uncanny ways or as Eugene Wigner put it, ‘unreasonably effective’.

Read the passage below and answer the questions that follow.
For nearly four centuries, the Atlantic slave trade brought millions of people into bondage. Scholars estimate that around 1.5 million people perished in the brutal middle passage across the Atlantic.
The slave trade linked Africa, Europe and the Americas in a horrific enterprise of death and torture and profit. Yet, in the middle of the 18th century, as the slave trade boomed like never before, some notable European observers saw it as a model of free enterprise and indeed of ‘liberty’ itself. They were not slave traders or slave- ship captains but economic thinkers, and very influential ones. They were a pioneering group of economic thinkers committed to the principle of laissez-faire: a term they themselves coined. United around the French official Vincent de Gournay (1712-1759), they were among the first European intellectuals to argue for limitations on government intervention in the economy. They organised campaigns for the deregulation of domestic and international trade, and they made the slave trade a key piece of evidence in their arguments.
For a generation, the relationship between slavery and capitalism has preoccupied historians. The publication of several major pieces of scholarship on the matter has won attention from the media. Scholars demonstrate that the Industrial Revolution, centred on the mass production of cotton textiles in the factories of England and New England, depended on raw cotton grown by slaves on plantations in the American South. Capitalists often touted the superiority of the industrial economies and their supposedly ‘free labour’. ‘Free labour’ means the system in which workers are not enslaved but free to contract with any manufacturer they chose, free to sell their labour. It means that there is a labour market, not a slave market.
But because ‘free labour’ was working with and dependent on raw materials produced by slaves, the simple distinction between an industrial economy of free labour on the one hand and a slave- based plantation system on the other falls apart. So too does the 1
 oundary between the southern ‘slave states’ and northern ‘free states’ in Ame rica. While the South grew rich from plantation agriculture that depended on slave labour, New England also grew rich off the slave trade, investing in the shipping and maritime insurance that made the transport of slaves from Africa to the United States possible and profitable. The sale of enslaved Africans brought together agriculture and industry, north and south, forming a global commercial network from which the modern world emerged.
It is only in the past few decades that scholars have come to grips with how slavery and capitalism intertwined. But for the 18th-century French thinkers who laid the foundations of laissez-faire capitalism, it made perfect sense to associate the slave trade with free enterprise. Their writings, which inspired the Scottish philosopher Adam Smith’s Wealth of Nations (1776), aimed to convince the French monarchy to deregulate key businesses such as the sale of grain and trade with Asia. Only a few specialists read them today.
Yet these pamphlets, letters and manuscripts clearly proclaim a powerful message: the birth of modern capitalism depended not only on the labour of enslaved people and the profits of the slave trade, but also on the example of slavery as a deregulated global enterprise.

The first beam was circulated through the collider on the morning of 10 September 2008. CERN successfully fired the protons around the tunnel in stages, three kilometres at a time. The particles were fired in a clockwise direction into the accelerator and successfully steered around it at 10:28 local time. The LHC successfully completed its first major test: after a series of trial runs, two white dots flashed on a computer screen showing the protons travelled the full length of the collider. It took less than one hour to guide the stream of particles around its inaugural circuit. CERN next successfully sent a beam of protons in a counterclockwise direction, taking slightly longer at one and a half hours due to a problem with the cryogenics, with the full circuit being completed at 14:59.
On 19 September 2008, a quench occurred in about 100 bending magnets in sectors 3 and 4, causing a loss of approximately six tonnes of liquid helium, which was vented into the tunnel, and a temperature rise of about 100 kelvin in some of the affected magnets. Vacuum conditions in the beam pipe were also lost. Shortly after the incident CERN reported that the most likely cause of the problem was a faulty electrical connection between two magnets, and that - due to the time needed to warm up the affected sectors and then cool them back down to operating temperature - it would take at least two months to fix it. Subsequently, CERN released a preliminary analysis of the incident on 16 October 2008, and a more detailed one on 5 December 2008. Both analyses confirmed that the incident was indeed initiated by a faulty electrical connection. A total of 53 magnets were damaged in the incident and were repaired or replaced during the winter shutdown.
In the original timeline of the LHC commissioning, the first "modest" high-energy collisions at a center-of-mass energy of 900 GeV were expected to take place before the end of September 2008, and the LHC was expected to be operating at 10 TeV by the time of the official inauguration on 21 October 2008. However, due to the delay caused by the above- mentioned incident, the collider was not operational until November 2009. Despite the delay,
LHC was officially inaugurated on 21 October 2008, in the presence of political leaders, science ministers from CERN's 20 Member States, CERN officials, and members of the worldwide scientific community.
On 30 March 2010, LHC set a record for high-energy collisions, by colliding proton beams at a combined energy level of 7 TeV. The attempt was the third that day, after two unsuccessful attempts in which the protons had to be "dumped" from the collider and new beams had to be injected. The event was described by CERN Director General Rolf Heuer as "It's a great day to be a particle physicist". According to a press release, CERN will run the LHC for 18-24 months with the objective of delivering enough data to the experiments to make significant advances across a wide range of physics channels.
CERN scientists estimate that if the Standard Model is correct, a single Higgs boson may be produced every few hours. At this rate, it may take about two to three years to collect enough data to discover the Higgs boson unambiguously. Similarly, it may take one year or more before sufficient results concerning supersymmetric particles have been gathered to draw meaningful conclusions.
The results of the first proton-proton collisions at energies higher than Fermilab's Tevatron proton-antiproton collisions have been published, yielding greater-than-predicted charged hadron production. The CMS paper reports that the increase in the production rate of charged hadrons when the center-of-mass energy goes from 0.9 TeV to 2.36 TeV exceeds the predictions of the theoretical models used in the analysis, with the excess ranging from 10% to 14%, depending upon which model is used. The charged hadrons were primarily mesons (kaons and pions).

After the Treaty of Versailles in 1919, the German defence establishment was eager to improve its compromised communications system, and recognised the potential of a signalling device that had originally been made for the business market. Dr Arthur Scherbius had developed his 'Enigma' machine, capable of transcribing coded information, in the hope of interesting commercial companies in secure communications. In 1923 he set up his Cipher Machines Corporation in Berlin to manufacture this product, and within three years the German navy was producing its own version, followed in 1928 by the army and in 1933 by the air force. Enigma allowed an operator to type in a message, then scramble it by means of three to five notched wheels, or rotors, which displayed different letters of the alphabet. The receiver needed to know the exact settings of these rotors in order to reconstitute the coded text. Over the years the basic machine became more complicated, as German code experts added plugs with electronic circuits. Britain and her allies first understood the problems posed by this machine in 1931, when a German spy, Hans Thilo Schmidt, allowed his French spymasters to photograph stolen Enigma operating manuals, although neither French nor British cryptanalysts could at first make headway in breaking the Enigma cipher. It was only after they had handed over details to the Polish Cipher Bureau that progress was made. Helped by its closer links to the German engineering industry, the Poles managed to reconstruct an Enigma machine, complete with internal wiring, and to read the Wehrmacht's messages between 1933 and 1938.

I. The Enigma machine was useful to the German Navy, Airforce and Army.
II. The German spy was possibly a double agent.

A survey was carried out to assess the acceptability of private insurance players. A group of 100 respondents was identified and they were to be queried on the following parameters : Reliability, Claim Settlements and Ethical Sales. The insurance companies to be surveyed were camouflaged as C1, C2, C3 and C4. The query was based on two factors: Acceptable and Non-acceptable. The chart below gives the details of the respondents who answered the queries as acceptable for the said parameters.
In the above chart, 1 does not necessarily represent C1. Similarly 2 may or may not represent C2. Also, the three parameters of 1 may not necessarily stand for the same company. For. eg: Reliability of 1 could be of company C1 while Claim Settlement of 1 could be of Company C2.
It was further observed that a single respondent had answered only one query on any one parameter i.e. no respondent had answered to two parameters that were asked for in the survey.
1. The total number of respondents who had accepted the companies C2 and C4 on all the parameters was 29 and 26 respectively.
2. C3 had equal number of respondents accepting it on at least two of the parameters and further the total number of respondents that C3 had on all the parameters was greater than the total number of respondents who had accepted C1 on all parameters put together.
3. C1 had witnessed different number of respondents for each of the three parameters.
4. C2 did not have 10 or 5 respondents giving a positive reply for any of the parameters.
Further to have a more comprehensive analysis of the survey a point system was adopted wherein the company for whom the number of respondents for any particular parameter was highest was awarded 5 points. Similarly, the company which witnessed second highest number of respondents for that same parameter was awarded 3 points, third highest was awarded a single point and the company which had the least number of respondents accepting it on that particular parameter was supposed to get zero points.

Who and what is an Indian? How we are to characterize the Indian diasporic community as 'Indian' given that it is constituted of such diverse elements as South Asian Hong Kong Muslims, Canadian Sikhs (or shall we say Sikh Canadians?), Punjabi Mexican Californians, Gujarati East Africans now settled in the U.S. by way of England, South African Hindus, and so forth? In the United States, at least, the Indian community has occupied a place of considerable privilege, and many Indians could deflect the moment of recognition that 'Indianness' and being 'American' do not always happily coincide. In recent years, with a declining economy on the one hand, and the congregation of Indians in clusters that visibly put them apart on the other hand, Indians have for the first time become the targets of racial attacks. The Indian woman in her 'native dress', with the vermillion dot on her forehead, is easily seen as an embodiment of sheer otherness, and so she has been perceived by the so-called "dot-busters", a gang of white teenagers operating in New Jersey who have already been responsible for several violent crimes against Indians. In North America and the U.K., the native Indian costume has come up for public scrutiny and discussion in an altogether different respect: Sikhs have insisted that they be exempt from the law that compels bicyclists and motorcyclists to wear helmets, for such helmets cannot be worn over turbans, and their religious faith requires Sikhs to wear turbans. The kirpan has been an issue of contention in California schools. The 'corner shop', a hallowed symbol (if we could recall our Dickens) of English life, is now mainly in the hands of Indians. The obvious question is not only, 'What do the English think of that', but also: 'If the English landscape has been so altered, what is English about England'? The diaspora, in short, affects the center as well. 
However unlike Indian communities across the world might be, they all maintain some sort of tenuous link with the motherland. The most likely candidate for a force of bonding would be, of all things, the Hindi feature film, a phenomenon unique to the Indian diaspora: what Hollywood is to Western Europe, the Bombay Hollywood ("Bollywood") is to the Middle East and East Africa. The modesty, not to mention puritanism, of the Hindi film is said to explain its appeal to the Islamic world; and though we may well contest that interpretation, it is worthy of note that Hindi films found in grocery and video stores across the U.S. often carry subtitles in Arabic, one language which is indubitably not spoken by any Indian community in the U.S. 
The Indian 'arranged marriage' might furnish another such facet of a 'common culture'. Newspapers published by Indian communities flourish everywhere, and they invariably carry a section with matrimonial ads. Though these very ads help Indians to 'locate' one another, they pose difficult questions about 'otherness', both the otherness' of Indians in relation to 'Americans', and the internal 'otherness' of certain Indians in relation to other Indians.
Q. Which of the following weakens the concept of “otherness” as mentioned in the passage?

Van Gogh drew and painted with watercolors while at school; few of these works survive and authorship is challenged on some of those that do. When he committed to art as an adult, he began at an elementary level by copying the Cours de dessin, edited by Charles Bargue and published by Goupil & Cie. Within his first two years he had began to seek commissions. In spring 1882, his uncle, Cornelis Marinus (owner of a renowned gallery of contemporary art in Amsterdam) asked him for drawings of the Hague. Van Gogh's work did not prove equal to his uncle's expectations. Marinus offered a second commission, this time specifying the subject matter in detail, but was once again disappointed with the result. Nevertheless, Van Gogh persevered. He improved the lighting of his atelier by installing variable shutters and experimented with a variety of drawing materials. For more than a year he worked on single figures- highly elaborated studies in “Black and White”, which at the time gained him only criticism. Today, they are recognized as his first masterpieces. Early in 1883, he undertook work on multi-figure compositions, which he based on the drawings. He had some of them photographed, but when his brother remarked that they lacked liveliness and freshness, Van Gogh destroyed them and turned to oil painting. By autumn 1882, Theo had enabled him to do his first paintings, but the amount Theo could supply was soon spent. Then, in spring 1883, Van Gogh turned to renowned Hague School artists like Weissenbruch and Blommers, and received technical support from them, as well as from painters like De Bock and Van der Weele, both Hague School artists of the second generation.
When he moved to Nuenen after the intermezzo in Drenthe, he began a number of large size paintings, but destroyed most. The Potato Eaters and its companion pieces- The Old Tower on the Nuenen cemetery and The Cottage- are the only to have survived. Following a visit to the Rijksmuseum, Van Gogh was aware that many of his faults were due to lack of technical experience. So he traveled to Antwerp and later to Paris to learn and develop his skill. More or less acquainted with Impressionist and Neo-impressionist techniques and theories, Van Gogh went to Arles to develop these new possibilities. But within a short time, older ideas on art and work reappeared: ideas such as series on related or contrasting subject matter, which would reflect the purposes of art. As his work progressed, he painted a great many Self-portraits. Already in 1884 in Nuenen he had worked on a series that was to decorate the dining room of a friend in Eindhoven. Similarly in Arles, in spring 1888 he arranged his Flowering Orchards into triptychs, began a series of figures that found its end in The Roulin Family, and finally, when Gauguin had consented to work and live in Arles side-by-side with Van Gogh, he started to work on the The Decoration for the Yellow House, which was by some accounts the most ambitious effort he ever undertook. Most of his later work is elaborating or revising its fundamental settings. In the spring of 1889, he painted another smaller group of orchards. In an April letter to Theo, he said, “I have 6 studies of spring, two of them large orchards. There is little time because these effects are so short-lived.”
The art historian Albert Boime was the first to show that Van Gogh- even in seemingly phantastical compositions like Starry Night- relied on reality. The White House at Night, shows a house at twilight with a prominent star with a yellow halo in the sky. Astronomers at Southwest Texas State University in San Marcos calculated that the star is Venus, which was bright in the evening sky in June 1890 when Van Gogh is believed to have painted the picture. The paintings from the Saint-Remy period are often characterized by swirls and spirals. The patterns of luminosity in these images have been shown to conform to Kolmogorov's statistical model of turbulence.
Q. Which of the following paintings was destroyed at the hands of Van Gogh?

Roots bend in response to gravity due to a regulated movement of the plant hormone auxin known as polar auxin transport. In roots, an increase in the concentration of auxin will inhibit cell expansion, therefore, the redistribution of auxin in the root can initiate differential growth in the elongation zone resulting in root curvature. A "tropism" is a plant movement triggered by stimuli. The term "geotropic" refers to a plant whose roots grow down into the soil as a response to gravity. Plants commonly exist in a state of "anisotropic growth," where roots grow downward and shoots grow upward. Anisotropic growth will continue even as a plant is turned sideways or upside down. In other words, no matter what you do to a plant within Earth's atmosphere, it will still grow roots down and stem up. The reason for this comes from the nature of a plant and its general response to gravity.
Upward growth of plant parts, against gravity, is called "negative geotropism", and downward growth of roots is called "positive geotropism".
In shoots, increasing the local concentration of auxin promotes cell expansion; this is the opposite of root cells.
In both roots and stems, auxin accumulates towards the gravity vector on the lower side. In roots, this results in the inhibition of cell expansion on the lower side and the concomitant curvature of the roots towards gravity. In stems, the auxin also accumulates on the lower side, however in this tissue it increases cell expansion and results in the shoot curving up.
What is the antonym of the word “concomitant”?

It is indeed true that the very possibility of a criticism which shall judge of aesthetic excellence must stand or fall with this other question of a beauty in itself, as an objective foundation for criticism. If there is an absolute beauty, it must be possible to work out a system of principles which shall embody its laws, - an aesthetic, in other words; and on the basis of that aesthetic to deliver a well-founded critical judgment. Is there, then, a beauty in itself? And if so, in what does it consist? We can approach such an aesthetic canon in two ways: from the standpoint of philosophy, which develops the idea of beauty as a factor in the system of our absolute values, side by side with the ideas of truth and of morality, or from the standpoint of empirical science. For our present purpose, we may confine ourselves to the empirical facts of psychology and physiology.
When I feel the rhythm of poetry, or of perfect prose, which is, of course, in its own way, no less rhythmical, every sensation of sound sends through me a diffusive wave of nervous energy. I am the rhythm because I imitate it in myself. I march to noble music in all my veins, even though I may be sitting decorously by my own hearthstone; and when I sweep with my eyes the outlines of a great picture, the curve of a Greek vase, the arches of a cathedral, every line is lived over again in my own frame. And when rhythm and melody and forms and colours give me pleasure, it is because the imitating impulses and movements that have arisen in me are such as suit, help, heighten my physical organization in general and in particular. A well-composed picture calls up in the spectator just such a balanced relation of impulses of attention and incipient movements as suits an organism which is also balanced- bilateral - in its own impulses to movement, and at the same time stable; and it is the correspondence of the suggested impulses with the natural movement that makes the composition good. The basis, in short, of any aesthetic experience - poetry, music, painting, and the rest - is beautiful through its harmony with the conditions offered our senses, primarily of sight and hearing, and through the harmony of the suggestions and impulses it arouses with the whole organism.
But the sensuous beauty of art does not exhaust the aesthetic experience. What of the special emotions - the gaiety or triumph, the sadness or peace or agitation - that hang about the work of art, and make, for many, the greater part of their delight in it? We are told by psychology that emotion is dependent on the organic excitations of any given idea. Think away our bodily feelings, and we think away fear, too. And set up the bodily changes and the feeling of them, and we have the emotion that belongs to them even without the idea. The same thing, on another level, is a familiar experience. Now the application of all this to aesthetics is clear. All these tensions, relaxations, - bodily “imitations” of the form, - have each the emotional tone which belongs to it. What makes the sense of peace in the atmosphere of the Low Countries? Only the tendency, on following those level lines of landscape, to assume ourselves the horizontal, and the restfulness which belongs to that posture. What is the beauty of the “Ulalume,” or “Kubla Khan,” or “Ueber alien Gipfeln”? It is the way in which the form in its exquisite fitness to our senses, and the emotion belonging to that particular form as organic reverberation there from, in its exquisite fitness to thought, create in us a delight quite unaccounted for by the ideas which they express. This is the essence of beauty, - the possession of a quality which excites the human organism to functioning harmonious with its own nature.
Q. Why has the author mentioned poems such as “Ulalume,” or “Kubla Khan," or “Ueber alien Gipfeln”

The passage given below is followed by a set of questions. Choose the most appropriate answer to each question.
If you want to understand the shifting balance of power in the world economy, it helps to know the names Jorge Paulo Lemann, Carlos Brito, and Frederico Curado. Lemann, Brazil’s richest man and the dealmaker behind the dollar 52 billion InBev-Anheuser-Busch merger and the dollar 3.3 billion purchase of Burger King, has just teamed up with Warren Buffett to acquire yet another major American company, H.J. Heinz, for dollar 23 billion. Brito, the Brazilian chief executive officer of Anheuser- Busch InBev, has launched a dollar 20 billion takeover bid for Mexico’s Grupo Modelo —the maker of Corona beer—and in the process prompted a U.S. antitrust suit. (AB InBev already sells almost one in five beers in the world.) And Curado, the CEO of Embraer, the world’s third- largest commercial planemaker, recently inked a dollar 4 billion deal to supply American Airlines with regional jets.
These Brazilian tycoons represent a new breed of emerging-market entrepreneurs who are introducing unprecedented competition into every sector of global business. Emerging- market countries are now home to more than 1,000 companies with annual sales above $1 billion. Foreign direct investment from developing and transitional economies has outpaced FDI from rich countries for more than a decade. It’s by now widely understood that power is flowing from north to south and west to east, from old corporate behemoths to agile startups. But to say that power is shifting from one continent or country to another, or that it’s dispersing among many new players, tells only part of the story. Nor is it enough to attribute these shifts to the impact of the Internet and other disruptive technologies.
Instead, the very nature of the power once wielded by established companies and the people who run them has changed. Rival CEOs continue to fight for dominance, but corporate power itself - the ability to influence the way consumers, competitors, and markets behave - is decaying. The Brazilian billionaires who now control multinational giants such as AB InBev are no less vulnerable than the more familiar names they’ve replaced. In the 21st century, power is easier to get but also harder to use and easier to lose.
To many people this trend may seem surprising. In the age of Occupy Wall Street and “too big to fail,” it’s unquestionable that income is concentrating and some are using money to gain political clout. Yet even the 1 Percent in the U.S. aren’t immune to sudden shifts in wealth. For all the rise in income inequality, the Great Recession also had a corrective effect, disproportionately affecting the incomes of the rich. According to Emmanuel Saez, an economics professor at the University of California at Berkeley, the economic crisis caused a 36.3 percent drop in the incomes of the top 1 percent of earners in the U.S., compared with an 11.6 percent drop for the remaining 99 percent. In 2012, Forbes said the top take-away from its list of the world’s billionaires was “churn,” with almost as many list members losing wealth (441) as gaining it (460). Corporate chiefs may earn much more than before, but tenure at the top has become more precarious. In 1992 a U.S. Fortune 500 CEO had a 36 percent chance of
retaining his job for the next five years; in 1998 that chance was down to 25 percent. According to management consultant John Challenger, the tenure of the average American CEO has declined from close to 10 years in the 1990s to about five and a half years. The position of executives in other countries is just as tenuous. In 2011 alone, CEOs at 14.4 percent of the world’s 2,500 biggest listed companies left their jobs.
The same goes for corporations themselves. A study by economists Diego Comin and Thomas Philippon showed that in 1980 a U.S. company in the top fifth of its industry had only a 10 percent risk of falling out of that tier in five years; two decades later, that likelihood had risen to 25 percent. In finance, banks are losing power and influence to nimbler hedge funds:
In the second half of 2010, in the midst of a sharp economic downturn, the top 10 hedge funds - most of them unknown to the general public - earned more than the world’s six largest banks combined. Multinationals are also more likely to suffer brand disasters that clobber their reputations, revenues, and valuations, as companies from BP (BP) to Nike (NKE) to News Corp. (NWS) can all attest. One study found that the five-year risk of such a disaster for companies owning the most prestigious global brands has risen in the past two decades from 20 percent to 82 percent.
In some respects, these are heartening developments. Just as the decay of power in politics has undermined authoritarian regimes, in business it has curtailed monopolies and oligopolies while giving consumers more choices, lower prices, and, in some cases at least, better quality. Even areas in which monopolies were once thought unavoidable, such as utilities, can now be opened to competition. Cultural barriers are increasingly irrelevant: To cite just one example, Alejandro Ramirez, a young entrepreneur from Morelia, Mexico, is one of the leading players in the cineplex business - in India. Ramirez’s company, Cinepolis, began as a one-screen movie house in the 1940s in provincial Michoacan state. It’s since become the largest cineplex company in Mexico and Central America and is now seeking to meet India’s demand for modern multiplexes - there are only about a thousand modern film screens for more than 1.2 billion people - by adding 500 screens in the next few years.
The growing power vacuum also entails dangers. It’s nurtured all manner of improvised groups, companies, and media outlets that evade traditional scrutiny and whose sponsors hide in the cacophony of the Web. It’s also created more opportunities for fraud and deceit.
When power is harder to use and keep, and it spreads to an ever-larger, ever-shifting cast of small players, forms of competition that threaten the social good and the survival of industries (overly aggressive business tactics designed to bankrupt rivals rather than maximize profits, for instance) are more likely to arise.
We can’t anticipate the many changes that will flow from power’s ebb, but we can adopt a mind-set that will minimize its more harmful effects. The first step is resisting elevator thinking, the obsession with who’s going up and who’s coming down. You can rank competitors at any given time by their assets, power, and achievements. But the picture this offers is ephemeral and misleading. The more we fixate on rankings, the more we risk ignoring or underestimating how much the waning of power is weakening all the competing parties, not only those in apparent decline.
We must also recognize that the decay of power creates fertile soil for those who seek to exploit the proliferation of actors, opinions, and proposals in ways ultimately counter to the public interest - consider the Wall Street wizards who championed toxic financial instruments as creative solutions. Devising enforceable safeguards to protect the public will become essential for policymakers worldwide.
In business and politics, the end of power carries risks as much as it presents opportunities.
When national and international leaders are, like Gulliver, tied down by thousands ofmicropowers, they’re less able to address the most pressing issues of the day - from climate change to economic crises to nuclear proliferation. The fundamental challenge before us is to welcome the advances of plural voices and innovation without driving ourselves into a crippling paralysis.

It was almost 15 years ago that I first met Baba Amte in Hemalkasa. I was reporting from the Nagpur legislature session and decided to travel to the place where Amte’s son Dr Prakash provides medical treatment for free to tribals from Gadchiroli and neighbouring districts from Andhra Pradesh. There was a long weekend and we decided to put it to good use by visiting the Amtes and seeing their work first hand. Dr Prakash told us to be ready at 7 am sharp and join Baba for a morning walk. Well, it was not at all a walk. We were literally jogging to keep pace with the 85 year young Baba as he sprinted with the spirit of a deer. Huffing and puffing, we asked him so many questions - personal included (he was an atheist and his wife Sadhana who joined us in the walk was an ardent devotee of Lord Shiva) - and Baba was more than happy to answer us. It was an amazing love story and it really takes something to stay married to a man who was crazy enough to inject himself with leprosy-causing bacteria to test the efficacy of the vaccine. While Baba was fired up by the cause, Sadhanatai believed in him and loved him in an absolute selfless manner.
Coming back to Baba, we asked him what future did he see for India when the communal fire seemed to be engulfing it. And he laughed. "Oh, this keeps happening all the time. We have seen this during Bapu’s time, then we saw during Khalistan and we have seen that again during the 90s. We have done well, haven’t we? I believe in youth and I know they will always shun violence," Baba said. We were amazed by the positivity he showed and we asked him if he was ever depressed in his life. "When you see people shunned by the society just because they were afflicted by a disease and when you see the life they go through, you know your life is far better. I have two eyes, two ears, all my limbs are absolutely fine. What more do you want to stay positive?" By the time we returned to the government rest house after the invigorating 'walk', we were fully mesmerized by the man. From Baba, who took up the Gandhian cause and followed it in true spirit, his wife Sadhana who simply followed him no questions asked, his sons Dr Prakash and Dr Vikas or his grandson who was not lured by any of the urban pleasures of life, each person was worthy of great respect.
Q. “.....the 85 year young Baba as he sprinted with the spirit of  a deer” implies that:

Read the passage carefully and answer the questions given

More and more companies, government agencies, educational institutions and philanthropic organisations are today in the grip of a new phenomenon: ‘metric fixation’. The key components of metric fixation are the belief that it is possible -and desirable - to replace professional judgment (acquired through personal experience and talent) with numerical indicators of comparative performance based upon standardised data (metrics); and that the best way to motivate people within these organisations is by attaching rewards and penalties to their measured performance.
The rewards can be monetary, in the form of pay for performance, say, or reputational, in the form of college rankings, hospital ratings, surgical report cards and so on. But the most dramatic negative effect of metric fixation is its propensity to incentivise gaming: that is, encouraging professionals to maximise the metrics in ways that are at odds with the larger purpose of the organisation. If the rate of major crimes in a district becomes the metric according to which police officers are promoted, then some officers will respond by simply not recording crimes or downgrading them from major offences to misdemeanours. Or take the case of surgeons. When the metrics of success and failure are made public - affecting their reputation and income - some surgeons will improve their metric scores by refusing to operate on patients with more complex problems, whose surgical outcomes are more likely to be negative. Who suffers? The patients who don’t get operated upon.
When reward is tied to measured performance, metric fixation invites just this sort of gaming. But metric fixation also leads to a variety of more subtle unintended negative consequences. These include goal displacement, which comes in many varieties: when performance is judged by a few measures, and the stakes are high (keeping one’s job, getting a pay rise or raising the stock price at the time that stock options are vested), people focus on satisfying those measures -often at the expense of other, more important organisational goals that are not measured. The best-known example is ‘teaching to the test’, a widespread phenomenon that has distorted primary and secondary education in the United States since the adoption of the No Child Left Behind Act of 2001.
Short-termism is another negative. Measured performance encourages what the US sociologist Robert K Merton in 1936 called ‘the imperious immediacy of interests … where the actor’s paramount concern with the foreseen immediate consequences excludes consideration of further or other consequences’. In short, advancing short-term goals at the expense of long-range considerations. This problem is endemic to publicly traded corporations that sacrifice long-term research and development, and the development of their staff, to the perceived imperatives of the quarterly report.
To the debit side of the ledger must also be added the transactional costs of metrics: the expenditure of employee time by those tasked with compiling and processing the metrics in the first place - not to mention the time required to actually read them. . . .
Q. All of the following can be a possible feature of the No Child Left Behind Act of 2001, EXCEPT:
