This quarrel was the saving of us, for while it was still raging, another sound came from the top of the hill on the side of the hamlet-the tramp of horses galloping. 3. And that was plainly the last signal of danger, for, the buccaneers turned at once and ran, separating in every direction, one seaward along the cove, one slant across the hill, and so on, so that in half a minute not a sign of them remained but Pew. 4. Him they had deserted, whether in sheer panic or out of revenge for his ill words and blows I know not; but there he remained behind, tapping up and down the road in a frenzy, and groping and calling for his comrades. 5.

Direction: Analyse the following passage and provide appropriate answers for these questions. 'Whatever actions are done by an individual in different embodiments, [s] he reaps the fruit of those actions in those very bodies or embodiments (in future existences)". A belief in karma entails, among other things, a focus on long run consequences, i.e., a long term orientation. Such an orientation implies that people who believe in karma may be more honest with themselves in general and in setting expectations in particular-a hypothesis we examine here. This research is based on three simple premises. First, because lower expectations often lead to greater satisfaction, individuals in general, and especially those who are sensitive to the gap between performance and expectations, have the incentive to and actually do "strategically" lower their expectations. Second, individuals with a long term orientation are likely to be less inclined to lower expectations in the hope of temporarily feeling better. Third, long term orientation and the tendency to lower expectations are at least partially driven by cultural factors. In India, belief in karma, with its emphasis on a longer term orientation, will therefore to some extent counteract the tendency to lower expectations. The empirical results support our logic; those who believe more strongly in karma are less influenced by disconfirmation sensitivity and therefore have higher expectations. Consumers make choices based on expectations of how alternative options will perform (i.e., expected utility). Expectations about the quality of a product also play a central role in subsequent satisfaction. These expectations may be based on a number of factors including the quality of a typical brand in a category, advertised quality, and disconfirmation sensitivity. Recent evidence suggests that consumers, who are more disconfirmation sensitive (i.e., consumers who are more satisfied when products perform better than expected or more, dissatisfied when products perform worse than expected) have lower expectations. However, there is little research concerning the role of culture- specific variables in expectation formation, particularly how they relate to the impact of disconfirmation sensitivity on consumer expectations. Consider the following assertion and conclusion: Assertion: The meaning of karma in the above passage (refers to first two lines of the paragraph in italics). Conclusion: Belief that long term consequences are important. Now read the following statements carefully: 1. The conclusion will always follow the assertion. 2. The conclusion may follow the assertion. 3. The conclusion may follow the assertion only if an individual lives long enough. 4. The conclusion cannot follow the assertion. Which of the following statement(s) is correct?

Read the following sentences and choose the option that best arranges them in a logical order. 1. As chroniclers of an incremental process, they discover that additional research makes it harder, not easier, to answer questions like: When was oxygen discovered? Who first conceived of energy conservation? 2. Simultaneously, these same historians confront growing difficulties in distinguishing the "scientific" component of past observation and belief from what their predecessors had readily labelled "error" and "superstition". 3. Increasingly, a few of them suspect that these are simply the wrong sorts of questions to ask. Perhaps science does not develop by the accumulation of individual discoveries and inventions. 4. In recent years, however, a few historians of science have been finding it more and more difficult to fulfill the functions that the concept of development-by- accumulation assigns to them.

Direction: Analyse the following passage and provide appropriate answers for these questions. An example of scientist who could measure without instruments is Enrico Fermi (1901-1954), a physicist who won the Nobel Prize in Physics in 1938. He had a well-developed knack for intuitive, even casual-sounding measurements. One renowned example of his measurement skills was demonstrated at the first detonation of the atom bomb, the Trinity Test site, on July 16, 1945, where he was one of the atomic scientists observing the blast from base camp. While final adjustments were being made to instruments used to measure the yield of the blast, Fermi was making confetti out of a page of notebook paper. As the wind from the initial blast wave began to blow through the camp, he slowly dribbled the confetti into the air, observing how far back it was scattered by the blast (taking the farthest scattered pieces as being the peak of the pressure wave). Fermi concluded that the yield must be greater than 10 kilotons. This would have been news, since other initial observers of the blast did not know that lower limit. After much analysis of the instrument readings, the final yield estimate was determined to be 18.6 kilotons. Like Eratosthenes, Fermi was aware of a rule relating one simple observation-the scattering of confetti in the wind-to a quantity he wanted to measure. The value of quick estimates was something Fermi was familiar with throughout his career. He was famous for teaching his students skills at approximation of fanciful-sounding quantities that, at first glance, they might presume they knew nothing about. The best-known example of such a "Fermi question" was Fermi asking his students to estimate the number of piano tuners in Chicago, when no one knows the answer. His students-science and engineering majors-would begin by saying that they could not possibly know anything about such a quantity. Of course, some solutions would be to simply do a count of every piano tuner perhaps by looking up advertisements, checking with a licensing agency of some sort, and so on. But Fermi was trying to teach his students how to solve problems where the ability to confirm the results would not be so easy. He wanted them to figure out that they knew something about the quantity in question. Suppose you apply the same logic as Fermi applied to confetti, which of the following statements would be the most appropriate?
- A.
  
  You can calculate the minimum pressure inside the cooker by calculating the maximum distance travelled by any of its parts after it explodes
- B.
  
  You can calculate the average potency of a fire cracker by calculating the distance covered by one of its bigger fragments
- C.
  
  You can easily find out the average potency of an earthquake by measuring the length of a crack it makes on the surface of the earth
- D.
  
  You can calculate the exact volume of water stored in a tank by measuring the distance covered by the stream of water coming out of the tap fixed on the lower corner of the tank
- E.
  
  All of the above conclusions can be drawn

Of course, some solutions would be to simply do a count of every piano tuner perhaps by looking up advertisements, checking with a licensing agency of some sort, and so on. But Fermi was trying to teach his students how to solve problems where the ability to confirm the results would not be so easy. He wanted them to figure out that they knew something about the quantity in question. Read the statements given below: 1. Atomic bomb detonation was a result of Fermi's Nobel Prize contribution. 2. Fermi's students respected him as a scientist. 3. Yield of atomic bomb can only be measured in Kilotons. Which of the following statement(s) can be inferred from the passage?
- A.
  
  1, 2
- B.
  
  2, 3
- C.
  
  1, 3
- D.
  
  2 only
- E.
  
  One of the three statements is correct

Direction: Analyse the following passage and provide appropriate answers for the questions. Soros, we must note, has never been a champion of free market capitalism. He has followed for nearly all his public life the political ideas of the late Sir Karl Popper who laid out a rather jumbled case for what he dubbed "the open society" in his The Open Society and Its Enemies (1953). Such a society is what we ordinarily call the pragmatic system in which politicians get involved in people's lives but without any heavy theoretical machinery to guide them, simply as the ad hoc parental authorities who are believed to be needed to keep us all on the straight and narrow. Popper was at one time a Marxist socialist but became disillusioned with that idea because he came to believe that systematic ideas do not work in any area of human concern. The Popperian open society Soros promotes is characterised by a very general policy of having no firm principles, not even those needed for it to have some constancy and integrity. This makes the open society a rather wobbly idea, since even what Popper himself regarded as central to all human thinking, critical rationalism, may be undermined by the openness of the open society since its main target is negative: avoid dogmatic thinking, and avoid anything that even comes close to a set of unbreachable principles. No, the open society is open to anything at all, at least for experimental purposes. No holds are barred, which, if you think about it, undermines even that very idea and becomes unworkable. Accordingly, in a society Soros regards suited to human community living, the state can manipulate many aspects of human life, including, of course, the economic behaviour of individuals and firms. It can control the money' supply, impose wage and price controls, dabble in demand or supply side economics, and do nearly everything a central planning board might- provided it does not settle into anyone policy firmly, unbendingly. That is the gist of Soros's Popperian politics. Soros distrusts capitalism In particular, because of the alleged inadequacy of neoclassical economics, the technical economic underpinnings of capitalist thinking offered up in many university economics departments. He, like many others outside and even inside the economics discipline, finds the arid reductionism of this social science false to the facts, and rightly so. But the defence of capitalist free markets does not rest on this position. Neo-classical thinking depends in large part on the 18th-and-19th century belief that human society operates according to laws, not unlike those that govern the physical universe. Most of social science embraced that faith, so economics isn't unusual in its loyalty to classical mechanics. Nor do all economists take the deterministic lawfulness of economic science literally-some understand that the laws begin to operate only once people embark upon economic pursuits. Outside their commercial ventures, people can follow different principles and priorities, even if it is undeniable that most of their endeavours have economic features. Yet, it would be foolish to construe religion or romance or even scientific inquiry as solely explicable by reference to the laws of economics. In his criticism of neo-classical economic science, then, George Soros has a point: the discipline is too dependent on Newtonian physics as the model of science. As a result, the predictions of economists who look at markets as if they were machines need to be taken with a grain of salt. Some-for example the school of Austrian economists-have made exactly that point against the neo- classical. Soros draws a mistaken inference: if one defence of the market is flawed, the market lacks defence. This is wrong. If it is true that from A we can infer B, it does not prove that Bean only be inferred from A; C or Z, too, might be a reason for B. According to the author which of the following statements could be true about critical rationalism.
- A.
  
  Ideas of critical rationalism underpin the foundation of neo- classical economics
- B.
  
  Ideas of critical rationalism underpin the foundation of laissez- faire
- C.
  
  Ideas of critical rationalism underpin the foundation of open society
- D.
  
  Ideas of critical rationalism underpin the foundation of Newtonian physics
- E.
  
  None of the above

Direction: Analyse the following passage, and provide appropriate answers for the questions. Popper claimed, scientific beliefs are universal in character, and have to be so if they are to serve us in explanation and prediction. For the universality of a scientific belief implies that, no matter how many instances we have found positive, there will always be an indefinite number of unexamined instances which may or may not also be positive. We have no good reason for supposing that any of these unexamined instances will be positive; or will be negative, so we must refrain from drawing any conclusions. On the other hand, a single negative instance is sufficient to prove that the belief is false, for such an instance is logically incompatible with the universal truth of the belief. Provided, therefore, that the instance is accepted as negative we must conclude that the scientific belief is false. In short, we can sometimes deduce that a universal scientific belief is false but we can never induce that a universal scientific belief is true. It is sometimes argued that this 'asymmetry' between verification and falsification is not nearly as pronounced as Popper declared it to be. Thus, there is no inconsistency in holding that a universal scientific belief is false despite any number of positive instances; and there is no inconsistency either in holding that a universal scientific belief is true despite the evidence of a negative instance. For the belief that an instance is negative is itself a scientific belief and may be falsified by experimental evidence, which we accept and which is inconsistent with it. When, for example, we draw a right- angled triangle on the surface of a sphere using parts of three great circles for its sides, and discover that for this triangle Pythagoras' Theorem does not hold, we may decide that this apparently negative instance is not really negative because it is not a genuine instance at all. Triangles drawn on the surfaces of spheres are not the sort of triangles which fall within the scope of Pythagoras' Theorem. Falsification, that is to say, is no more capable of yielding conclusive rejections of scientific belief than verification is of yielding conclusive acceptances of scientific beliefs. The asymmetry between falsification and verification, therefore, has less logical significance than Popper supposed. We should, though, resist this reasoning. Falsifications may not be conclusive, for the acceptances on which rejections are based are always provisional acceptances. But, nevertheless, it remains the case that, in falsification, if we accept falsifying claims then, to remain consistent, we must reject falsified claims. On the other hand, although verifications are also not conclusive, our acceptance or rejection of verifying instances has no implications concerning the acceptance or rejection of verified claims. Falsifying claims sometimes give us a good reason for rejecting a scientific belief, namely when the claims are accepted. But verifying claims, even when accepted, give us no good and appropriate reason for accepting any scientific belief, because any such reason would have to be inductive to be appropriate and there are no good inductive reasons. The statement, "this 'asymmetry' between verification and falsification is not nearly as pronounced as Popper declared it to be", implies that
- A.
  
  Falsification is better than verification in universal acceptance of scientific beliefs
- B.
  
  Verification is better than falsification in universal acceptance of scientific beliefs
- C.
  
  Both falsification and verification together can result in universal acceptance of scientific beliefs
- D.
  
  Capability of falsification in acceptance of scientific beliefs is not better than that of verification in rejection of scientific beliefs
- E.
  
  Capability of falsification in rejection of scientific beliefs is not always better than that of verification in acceptance of scientific beliefs
