        C.      The length of one-degree arc would be less near the equatorial latitudes than at the poles.
        D.      One way of doing that is to determine the length of the arc along a chosen longitude or meridian at one-degree latitude separation.
        E.      While it was generally known that the earth was not a sphere but an ‘oblate spheroid’, more curved at the equator and flatter at the poles, the question of ‘how much more’ was yet to be established.

25.   A.      But in the industrial era, if you need to destroy the enemy’s productive capacity means bombing the factories which are located in the cities.

        D.      How do you battle with your enemy?
        E.      The idea is to destroy the enemy’s productive capacity, and depending upon the economic foundation, that productive capacity is different in each case.

27.   A.      Passivity is not, of course, universal.
        B.      In areas where there are no lords or laws, or in frontier zones where all men go armed, the attitude of the peasantry may well be different.
        C.      So indeed it may be on the fringe of the unsubmissive.
        D.      However, for most of the soil-bound peasants the problem is not whether to be normally passive or active, but when to pass from one state to another.
        E.      This depends on an assessment of the political situation.

28.   A.      The situations in which violence occurs and the nature of that violence tends to be clearly defined at least in theory, as in the proverbial Irishman’s question: ‘Is this a private fight or can anyone join in?’
        B.      So the actual risk to outsiders, though no doubt higher than our societies, is calculable.
        C.      Probably the only uncontrolled applications of force are those of social superiors to social inferiors and even here there are probably some rules.

        B.      Humankind lingers unregenerately in Plato’s cave, still revelling, its age-old habit, in mere images of truth.

32.   A.      Both parties use capital and labour in the struggle to secure property rights.
        B.      The thief spends time and money in his attempt to steal (he buys wire cutters) and the legitimate property owner expends resources to prevent the theft (he buys locks).
        C.      A social cost of theft is that both the thief and the potential victim use resources to gain or maintain control over property.
        D.      These costs may escalate as a type of technological arms race unfolds.      
        E.      A bank may purchase more and more complicated and sophisticated safes, forcing safecrackers to invest further in safecracking equipment.

        D.      The fundamental concept: Prices are not predictable, but the mathematical laws of chance can describe their fluctuations.
        E.      This is how what business schools now call modern finance was born.

40.   A.      Similarly, turning to caste, even though being lower caste is undoubtedly a separate cause of disparity, its impact is all the greater when the lower-caste families also happen to be poor.
        B.      Belonging to a privileged class can help a woman to overcome many barriers that obstruct women from less thriving classes.
        C.      It is the interactive presence of these two kinds of deprivation—being low class and being female—that massively impoverishes women from the less privileged classes.
        D.      A congruence of class deprivation and gender discrimination can blight the lives of poorer women very severely.
        E.      Gender is certainly a contributor to societal inequality, but it does not act independently of class.

41.   A.      When identity is thus ‘defined by contrast’, divergence with the West becomes central.
        B.      Indian religious literature such as the Bhagavad Gita or the Tantric texts, which are identified as differing from secular writings seen as ‘western’, elicits much greater interest in the West than do other Indian writings, including India’s long history of heterodoxy.
        C.      There is a similar neglect of Indian writing on non-religious subjects, from mathematics, epistemology and natural science to economics and linguistics.
        D.      Through selective emphasis that point up differences with the West, other civilizations can, in this way, be redefined in alien terms, which can be exotic and charming, or else bizarre and terrifying, or simply strange and engaging.
        E.      The exception is the Kamasutra in which western readers have managed to cultivate an interest.

TYPE II: Six Sentences—First and Last Sentences Fixed

Directions for Questions 42 to 51: Sentences given in each question, when properly sequenced, form a coherent paragraph. The first and last sentences are 1 and 6, and the four in between are labelled A, B, C and D. Choose the most logical order of these four sentences from among the four given choices to construct a coherent paragraph from sentences 1 to 6.

42.   1.       Security inks exploit the same principle that causes the vivid and constantly changing colours of a film of oil on water.
        A.      When two rays of light meet each other after being reflected from these different surfaces, they have each travelled slightly different distances.
        B.      The key is that the light is bouncing off two surfaces, that of the oil and that of the water layer below it.
        C.      The distance the two rays travel determines which wavelengths, and hence colours, interfere constructively and look bright.
        D.      Because light is an electromagnetic wave, the peaks and troughs of each ray then interfere either constructively, to appear bright, or destructively, to appear dim.
        6.       Since the distance the rays travel changes with the angle as you look at the surface, different colours look bright from different viewing angles.

43.   1.       Commercially reared chicken can be unusually aggressive, and are often kept in darkened sheds to prevent them pecking at each other.
        A.      The birds spent far more of their time—up to a third—pecking at the inanimate objects in the pens, in contrast to birds in other pens which spent a lot of time attacking others.
        B.      In low light conditions, they behave less belligerently, but are more prone to ophthalmic disorders and respiratory problems.
        C.      In an experiment, aggressive head-pecking was all but eliminated among birds in the enriched environment.
        D.      Altering the birds’ environment, by adding bales of wood-shavings to their pens, can work wonders.
        6.       Bales could diminish aggressiveness and reduce injuries; they might even improve productivity, since a happy chicken is a productive chicken.

44.   1.       The concept of a ‘nation-state’ assumes a complete correspondence between the boundaries of the nation and the boundaries of those who live in a specific state.
        A.      Then there are members of national collectivities who live in other countries, making a mockery of the concept.
        B.      There are always people living in particular states who are not considered to be (and often do not consider themselves to be) members of the hegemonic nation.
        C.      Even worse, there are nations which never had a state or which are divided across several states.
        D.      This, of course, has been subject to severe criticism and is virtually everywhere a fiction.
        6.       However, the fiction has been, and continues to be, at the basis of nationalist ideologies.

45.   1.       In the sciences, even questionable examples of research fraud are harshly punished.
        A.      But no such mechanism exists in the humanities—much of what humanities researchers call research does not lead to results that are replicable by other scholars.
        B.      Given the importance of interpretation in historical and literary scholarship, humanities researchers are in a position where they can explain away deliberate and even systematic distortion.
        C.      Mere suspicion is enough for funding to be cut off; publicity guarantees that careers can be effectively ended.
        D.      Forgeries which take the form of pastiches in which the forger intersperses fake and real parts can be defended as mere mistakes or aberrant misreading.
        6.       Scientists fudging data have no such defences.

46.   1.       Horses and communism were, on the whole, a poor match.
        A.      Fine horses bespoke the nobility the party was supposed to despise.
        B.      Communist leaders, when they visited villages, preferred to see cows and pigs.
        C.      Although a working horse was just about tolerable, the communists were right to be wary.
        D.      Peasants from Poland to the Hungarian Pustza preferred their horses to party dogma.
        6.       “A farmer’s pride is his horse; his cow may be thin but his horse must be fat,” went a Slovak saying.

47.   1.       Making people laugh is tricky.
        A.      At times, the intended humour may simply not come off.
        B.      Making people laugh while trying to sell them something is a tougher challenge, since the commercial can fall flat on two grounds.
        C.      There are many advertisements which do amuse but do not even begin to set the cash tills ringing.
        D.      Again, it is rarely sufficient for an advertiser simply to amuse the target audience in order to reap the sales benefit.
        6.       There are indications that in substituting the hard sell for a more entertaining approach, some agencies have rather thrown out the baby with the bath water.

48.   1.       Picture a termite colony, occupying a tall mud hump on an African plain.
        A.      Hungry predators often invade the colony and unsettle the balance.
        B.      The colony flourishes only if the proportion of soldiers to workers remains roughly the same, so that the queen and workers can be protected by the soldiers, and the queen and soldiers can be serviced by the workers.
        C.      But its fortunes are presently restored, because the immobile queen, walled in well below ground level, lays eggs not only in large enough numbers, but also in the varying proportions required.
        D.      The hump is alive with worker termites and soldier termites going about their distinct kinds of business.

49.   1.       According to recent research, the critical period for developing language skills is between the ages of three and five and a half years.
        A.      The read-to child already has a large vocabulary and a sense of grammar and sentence structure.
        B.      Children who are read to in these years have a far better chance of reading well in school, indeed, of doing well in all their subjects.
        C.      And the reason is actually quite simple.
        D.      This correlation is far and away the highest yet found between home influences and school success.
        6.       Her comprehension of language is therefore very high.

50.   1.       High-powered outboard motors were considered to be one of the major threats to the survival of the Beluga whales.
        A.      With these, hunters could approach Belugas within hunting range and profit from its inner skin and blubber.
        B.      To escape an approaching motor, Belugas have learned to dive to the ocean bottom and stay there for up to 20 minutes, by which time the confused predator has left.
        C.      Today, however, even with much more powerful engines, it is difficult to come close, because the whales seem to disappear suddenly just when you thought you had them in your sights.
        D.      When the first outboard engines arrived in the early 1930s, one came across 4 and 8 HP motors.
        6.       Belugas seem to have used their well-known sensitivity to noise to evolve an ‘avoidance’ strategy to outsmart hunters and their powerful technologies.

51.   1.       The reconstruction of history by post-revolutionary science texts involves more than a multiplication of historical misconstructions.
        A.      Because they aim quickly to acquaint the student with what the contemporary scientific community thinks it knows, textbooks treat the various experiments, concepts, laws and theories of the current normal science as separately and as nearly seriatim as possible.
        B.      Those misconstructions render revolutions invisible; the arrangement of the still visible material in science texts implies a process that, if it existed, would deny revolutions a function.
        C.      But when combined with the generally unhistorical air of science writing and with the occasional systematic misconstruction, one impression is likely to follow.
        D.      As pedagogy this technique of presentation is unexceptionable.
        6.       Science has reached its present state by a series of individual discoveries and inventions that, when gathered together, constitute the modern body of technical knowledge.
