CAT 2006 Exam Paper

Answer questions 6 to 10 on the basis of the information given below. Mathematicians are assigned a number called Erdös number, (named after the famous mathematician, Paul Erdös). Only Paul Erdös himself has an Erdös number of zero. Any mathematician who has written a research paper with Erdös has an Erdös number of 1. For other mathematicians, the calculation of his/her Erdös number is illustrated below: Suppose that a mathematician X has co-authored papers with several other mathematicians. From among them, mathematician Y has the smallest Erdös number. Let the Erdös number of Y be y. Then X has an Erdös number of y + 1. Hence any mathematician with no co-authorship chain connected to Erdös has an Erdös number of infinity. In a seven day long mini-conference organized in memory of Paul Erdös, a close group of eight mathematicians, call them A, B, C, D, E, F, G and H, discussed some research problems. At the beginning of the conference, A was the only participant who had an infinite Erdös number. Nobody had an Erdös number less than that of F. On the third day of the conference F co-authored a paper jointly with A and C. This reduced the average Erdös number of the group of eight mathematicians to 3. The Erdös numbers of B, D, E, G and H remained unchanged with the writing of this paper. Further, no other co-authorship among any three members would have reduced the average Erdös number of the group of eight to as low as 3. At the end of the third day, five members of this group had identical Erdös numbers while the other three had Erdös numbers distinct from each other. On the fifth day, E co-authored a paper with F which reduced the group‘s average Erdös number by 0.5. The Erdös numbers of the remaining six were unchanged with the writing of this paper. No other paper was written during the conference.

Answer the questions 11 to 15 on the basis of the information given below.
Two traders, Chetan and Michael, were involved in the buying and selling of MCS shares over five trading days. At the beginning of the first day, the MCS share was priced at Rs. 100, while at the end of the fifth day it was priced at Rs. 110. At the end of each day, the MCS share price either went up by Rs. 10, or else, it came down by Rs. 10. Both Chetan and Michael took buying and selling decisions at the end of each trading day. The beginning price of MCS share on a given day was the same as the ending price of the previous day. Chetan and Michael started with the same number of shares and amount of cash, and had enough of both. Below are some additional facts about how Chetan and Michael traded over the five trading days. Each day if the price went up, Chetan sold 10 shares of MCS at the closing price. On the other hand, each day if the price went down, he bought 10 shares at the closing price. If on any day, the closing price was above Rs. 110, then Michael sold 10 shares of MCS, while if it was below Rs. 90, he bought 10 shares, all at the closing price.

11. If Chetan sold 10 shares of MCS on three consecutive days, while Michael sold 10 shares only once during the five days, what was the price of MCS at the end of day 3?
(1) Rs. 90
(2) Rs. 100
(3) Rs. 110
(4) Rs. 120
(5) Rs. 130

12. If Michael ended up with Rs. 100 less cash than Chetan at the end of day 5, what was the difference in the number of shares possessed by Michael and Chetan (at the end of day 5)?
(1) Michael had 10 less shares than Chetan.
(2) Michael had10 more shares than Chetan.
(3) Chetan had 10 more shares than Michael.
(4) Chetan had 20 more shares than Michael.
(5) Both had the same number of shares.

13. If Chetan ended up with Rs. 1300 more cash than Michael at the end of day 5, what was the price of MCS share at the end of day 4?
(1) Rs. 90
(2) Rs. 100
(3) Rs. 110
(4) Rs. 120
(5) Not uniquely determinable

14. What could have been the maximum possible increase in combined cash balance of Chetan and Michael at the end of the fifth day?
(1) Rs. 3700
(2) Rs. 4000
(3) Rs. 4700
(4) Rs. 5000
(5) Rs. 6000

15. If Michael ended up with 20 more shares than Chetan at the end of day 5, what was the price of the share at the end of day 3?
(1) Rs. 90
(2) Rs. 100
(3) Rs. 110
(4) Rs. 120
(5) Rs. 130

Answer questions 16 to 20 on the basis of the information given below.
A significant amount of traffic flows from point S to point T in the one-way street network shown below. Points A, B, C, and D are junctions in the network, and the arrows mark the direction of traffic flow. The fuel cost in rupees for travelling along a street is indicated by the number adjacent to the arrow representing the street.
Motorists travelling from point S to point T would obviously take the route for which the total cost of travelling is the minimum. If two or more routes have the same least travel cost, then motorists are indifferent between them. Hence, the traffic gets evenly distributed among all the least cost routes. The government can control the flow of traffic only by levying appropriate toll at each junction. For example, if a motorist takes the route S-A-T (using junction A alone), then the total cost of travel would be Rs. 14 (i.e. Rs. 9 + Rs. 5) plus the toll charged at junction A.

16. If the government wants to ensure that all motorists travelling from S to T pay the same amount (fuel costs and toll combined) regardless of the route they choose and the street from B to C is under repairs (and hence unusable), then a feasible set of toll charged (in rupees) at junctions A, B, C, and D respectively to achieve this goal is:
(1) 2, 5, 3, 2
(2) 0, 5, 3, 1
(3) 1, 5, 3, 2
(4) 2, 3, 5, 1
(5) 1, 3, 5, 1

17. If the government wants to ensure that no traffic flows on the street from D to T, while equal amount of traffic flows through junctions A and C, then a feasible set of toll charged (in rupees) at junctions A, B, C, and D respectively to achieve this goal is:
(1) 1, 5, 3, 3
(2) 1, 4, 4, 3
(3) 1, 5, 4, 2
(4) 0, 5, 2, 3
(5) 0, 5, 2, 2

18. If the government wants to ensure that all routes from S to T get the same amount of traffic, then a feasible set of toll charged (in rupees) at junctions A, B, C, and D respectively to achieve this goal is:
(1) 0, 5, 2, 2
(2) 0, 5, 4, 1
(3) 1, 5, 3, 3
(4) 1, 5, 3, 2
(5) 1, 5, 4, 2

19. If the government wants to ensure that the traffic at S gets evenly distributed along streets from S to A, from S to B, and from S to D, then a feasible set of toll charged (in rupees) at junctions A, B, C, and D respectively to achieve this goal is:
(1) 0, 5, 4, 1
(2) 0, 5, 2, 2
(3) 1, 5, 3, 3
(4) 1, 5, 3, 2
(5) 0, 4, 3, 2

20. The government wants to devise a toll policy such that the total cost to the commuters per trip is minimized. The policy should also ensure that not more than 70 per cent of the total traffic passes through junction B. The cost incurred by the commuter travelling from point S to point T under this policy will be:
(1) Rs. 7
(2) Rs. 9
(3) Rs. 10
(4) Rs. 13
(5) Rs. 14

Directions for Questions 31 to 35: Each of the following questions has a paragraph from which the last sentence has been deleted. From the given options, choose the one that completes the paragraph in the most appropriate way.
31. I am sometimes attacked for imposing 'rules‘. Nothing could be further from the truth. I hate rules. All I do is report on how consumers react to different stimuli. I may say to a copywriter, “Research shows that commercials with celebrities are below average in persuading people to buy products. Are you sure you want to use a celebrity?” Call that a rule? Or I may say to an art director, “Research suggests that if you set the copy in black type on a white background, more people will read it than if you set it in white type on a black background.”
(1) Guidance based on applied research can hardly qualify as ‘rules’.
(2) Thus, all my so called ‘rules’ are rooted in applied research.
(3) A suggestion perhaps, but scarcely a rule.
(4) Such principles are unavoidable if one wants to be systematic about consumer behaviour.
(5) Fundamentally it is about consumer behaviour - not about celebrities or type settings.

32. Relations between the factory and the dealer are distant and usually strained as the factory tries to force cars on the dealers to smooth out production. Relations between the dealer and the customer are equally strained because dealers continuously adjust prices - make deals - to adjust demand with supply while maximizing profits. This becomes a system marked by a lack of long-term commitment on either side, which maximize feelings of mistrust. In order to maximize their bargaining positions, everyone holds back information - the dealer about the product and the consumer about his true desires.
(1) As a result, ‘deal making’ becomes rampant, without concern for customer satisfaction.
(2) As a result, inefficiencies creep into the supply chain.
(3) As a result, everyone treats the other as an adversary, rather than as an ally.
(4) As a result, fundamental innovations are becoming scarce in the automobile industry.
(5) As a result, everyone loses in the long run.

33. In the evolving world order, the comparative advantage of the United States lies in its military force. Diplomacy and international law have always been regarded as annoying encumbrances, unless they can be used to advantage against an enemy. Every active player in world affairs professes to seek only peace and to prefer negotiation to violence and coercion.
(1) However, diplomacy has often been used as a mask by nations which intended to use force.
(2) However, when the veil is lifted, we commonly see that diplomacy is understood as a disguise for the rule of force.
(3) However, history has shown that many of these nations do not practice what they profess.
(4) However, history tells us that peace is professed by those who intend to use violence.
(5) However, when unmasked, such nations reveal a penchant for the use of force.

34. Age has a curvilinear relationship with the exploitation of opportunity. Initially, age will increase the likelihood that a person will exploit an entrepreneurial opportunity because people gather much of the knowledge necessary to exploit opportunities over the course of their lives, and because age provides credibility in transmitting that information to others. However, as people become older, their willingness to bear risks declines, their opportunity costs rise, and they become less receptive to new information.
(1) As a result, people transmit more information rather than experiment with new ideas as they reach an advanced age.
(2) As a result, people are reluctant to experiment with new ideas as they reach an advanced age.
(3) As a result, only people with lower opportunity costs exploit opportunity when they reach an advanced age.
(4) As a result, people become reluctant to exploit entrepreneurial opportunities when they reach an advanced age.
(5) As a result, people depend on credibility rather than on novelty as they reach an advanced age.

35. We can usefully think of theoretical models as maps, which help us navigate unfamiliar territory. The most accurate map that it is possible to construct would be of no practical use whatsoever, for it would be an exact replica, on exactly the same scale, of the place where we were. Good maps pull out the most important features and throw away a huge amount of much less valuable information. Of course, maps can be bad as well as good - witness the attempts by medieval Europe to produce a map of the world. In the same way, a bad theory, no matter how impressive it may seem in principle, does little or nothing to help us understand a problem.
(1) But good theories, just like good maps, are invaluable, even if they are simplified.
(2) But good theories, just like good maps, will never represent unfamiliar concepts in detail.
(3) But good theories, just like good maps, need to balance detail and feasibility of representation.
(4) But good theories, just like good maps, are accurate only at a certain level of abstraction.
(5) But good theories, just like good maps, are useful in the hands of a user who knows their limitations.

Directions for Questions 36 to 40: The passage given below is followed by a set of questions. Choose the most appropriate answer to each question.
Fifteen years after communism was officially pronounced dead, its spectre seems once again to be haunting Europe. Last month, the Council of Europe‘s parliamentary assembly voted to condemn the crimes of totalitarian communist regimes,“ linking them with Nazism and complaining that communist parties are still legal and active in some countries.“Now Goran Lindblad, the conservative Swedish MP behind the resolution, wants to go further. Demands that European Ministers launch a continent-wide anti-communist campaign - including school textbook revisions, official memorial days, and museums - only narrowly missed the necessary two-thirds majority. Mr. Lindblad pledged to bring the wider plans back to the Council of Europe in the coming months. He has chosen a good year for his ideological offensive: this is the 50th anniversary of Nikita Khrushchev‘s denunciation of Josef Stalin and the subsequent Hungarian uprising, which will doubtless be the cue for further excoriation of the communist record. Paradoxically, given that there is no communist government left in Europe outside Moldova, the attacks have if anything, become more extreme as time has gone on. A clue as to why that might be can be found in the rambling report by Mr. Lindblad that led to the Council of Europe declaration. Blaming class struggle and public ownership, he explained different elements of communist ideology such as equality or social justice still seduce many “and a sort of nostalgia for communism is still alive.” Perhaps the real problem for Mr. Lindblad and his right-wing allies in Eastern Europe is that communism is not dead enough - and they will only be content when they have driven a stake through its heart. The fashionable attempt to equate communism and Nazism is in reality a moral and historical nonsense. Despite the cruelties of the Stalin terror, there was no Soviet Treblinka or Sorbibor, no extermination camps built to murder millions. Nor did the Soviet Union launch the most devastating war in history at a cost of more than 50 million lives - in fact it played the decisive role in the defeat of the German war machine. Mr. Lindblad and the Council of Europe adopt as fact the wildest estimates of those killed by communist regimes (mostly in famines) from the fiercely contested Black Book of Communism, which also underplays the number of deaths attributable to Hitler. But, in any case, none of this explains why anyone might be nostalgic in former communist states, now enjoying the delights of capitalist restoration. The dominant account gives no sense of how communist regimes renewed themselves after 1956 or why Western leaders feared they might overtake the capitalist world well into the 1960s. For all its brutalities and failures, communism in the Soviet Union, Eastern Europe, and elsewhere delivered rapid industrialization, mass education, job security, and huge advances in social and gender equality. Its existence helped to drive up welfare standards in the West, and provided a powerful counterweight to Western global domination.
It would be easier to take the Council of Europe‘s condemnation of communist state crimes seriously if it had also seen fit to denounce the far bloodier record of European colonialism - which only finally came to an end in the 1970s. This was a system of racist despotism, which dominated the globe in Stalin‘s time. And while there is precious little connection between the ideas of fascism and communism, there is an intimate link between colonialism and Nazism. The terms lebensraum and konzentrationslager were both first used by the German colonial regime in south-west Africa (now Namibia), which committed genocide against the Herero and Nama peoples and bequeathed its ideas and personnel directly to the Nazi party. Around 10 million Congolese died as a result of Belgian forced labour and mass murder in the early twentieth century; tens of millions perished in avoidable or enforced famines in British-ruled India; up to a million Algerians died in their war for independence, while controversy now rages in France about a new law requiring teachers to put a positive spin on colonial history. Comparable atrocities were carried out by all European colonialists, but not a word of condemnation from the Council of Europe. Presumably, European lives count for more. No major twentieth century political tradition is without blood on its hands, but battles over history are more about the future than the past. Part of the current enthusiasm in official Western circles for dancing on the grave of communism is no doubt about relations with today‘s Russia and China. But it also reflects a determination to prove there is no alternative to the new global capitalist order - and that any attempt to find one is bound to lead to suffering. With the new imperialism now being resisted in the Muslim world and Latin America, growing international demands for social justice and ever greater doubts about whether the environmental crisis can be solved within the existing economic system, the pressure for alternatives will increase.

36. Among all the apprehensions that Mr. Goran Lindblad expresses against communism, which one gets admitted, although indirectly, by the author?
(1) There is nostalgia for communist ideology even if communism has been abandoned by most European nations.
(2) Notions of social justice inherent in communist ideology appeal to critics of existing systems.
(3) Communist regimes were totalitarian and marked by brutalities and large scale violence.
(4) The existing economic order is wrongly viewed as imperialistic by proponents of communism.
(5) Communist ideology is faulted because communist regimes resulted in economic failures.

37. What, according to the author, is the real reason for a renewed attack against communism?
(1) Disguising the unintended consequences of the current economic order such as social injustice and environmental crisis.
(2) Idealising the existing ideology of global capitalism.
(3) Making communism a generic representative of all historical atrocities, especially those perpetrated by the European imperialists.
(4) Communism still survives, in bits and pieces, in the minds and hearts of people.
(5) Renewal of some communist regimes has led to the apprehension that communist nations might overtake the capitalists.

38. The author cites examples of atrocities perpetrated by European colonial regimes in order to
(1) compare the atrocities committed by colonial regimes with those of communist regimes.
(2) prove that the atrocities committed by colonial regimes were more than those of communist regimes.
(3) prove that, ideologically, communism was much better than colonialism and Nazism.
(4) neutralise the arguments of Mr.Lindblad and to point out that the atrocities committed by colonial regimes were more than those of communist regimes.
(5) neutralise the arguments of Mr. Lindblad and to argue that one needs to go beyond and look at the motives of these regimes.

39. Why, according to the author, is Nazism closer to colonialism than it is to communism?
(1) Both colonialism and Nazism were examples of tyranny of one race over another.
(2) The genocides committed by the colonial and the Nazi regimes were of similar magnitude.
(3) Several ideas of the Nazi regime were directly imported from colonial regimes.
(4) Both colonialism and Nazism are based on the principles of imperialism.
(5) While communism was never limited to Europe, both the Nazis and the colonialists originated in Europe.

40. Which of the following cannot be inferred as a compelling reason for the silence of the Council of Europe on colonial atrocities?
(1) The Council of Europe being dominated by erstwhile colonialists.
(2) Generating support for condemning communist ideology.
(3) Unwillingness to antagonize allies by raking up an embarrassing past.
(4) Greater value seemingly placed on European lives.
(5) Portraying both communism and Nazism as ideologies to be condemned.

Directions for Questions 41 to 45: The passage given below is followed by a set of five questions. Choose the most appropriate answer to each question.
My aim is to present a conception of justice which generalizes and carries to a higher level of abstraction the familiar theory of the social contract. In order to do this we are not to think of the original contract as one to enter a particular society or to set up a particular form of government. Rather, the idea is that the principles of justice for the basic structure of society are the object of the original agreement. They are the principles that free and rational persons concerned to further their own interests would accept in an initial position of equality. These principles are to regulate all further agreements; they specify the kinds of social cooperation that can be entered into and the forms of government that can be established. This way of regarding the principles of justice, I shall call justice as fairness. Thus, we are to imagine that those who engage in social cooperation choose together, in one joint act, the principles which are to assign basic rights and duties and to determine the division of social benefits. Just as each person must decide by rational reflection what constitutes his good, that is, the system of ends which it is rational for him to pursue, so a group of persons must decide once and for all what is to count among them as just and unjust. The choice which rational men would make in this hypothetical situation of equal liberty determines the principles of justice. In ‘justice as fairness’, the original position is not an actual historical state of affairs. It is understood as a purely hypothetical situation characterized so as to lead to a certain conception of justice. Among the essential features of this situation is that no one knows his place in society, his class position or social status, nor does anyone know his fortune in the distribution of natural assets and abilities, his intelligence, strength, and the like. I shall even assume that the parties do not know their conceptions of the good or their special psychological propensities. The principles of justice are chosen behind a veil of ignorance. This ensures that no one is advantaged or disadvantaged in the choice of principles by the outcome of natural chance or the contingency of social circumstances. Since all are similarly situated and no one is able to design principles to favor his particular condition, the principles of justice are the result of a fair agreement or bargain. Justice as fairness begins with one of the most general of all choices which persons might make together, namely, with the choice of the first principles of a conception of justice which is to regulate all subsequent criticism and reform of institutions. Then, having chosen a conception of justice, we can suppose that they are to choose a constitution and a legislature to enact laws, and so on, all in accordance with the principles of justice initially agreed upon. Our social situation is just if it is such that by this sequence of hypothetical agreements we would have contracted into the general system of rules which defines it. Moreover, assuming that the original position does determine a set of principles, it will then be true that whenever social institutions satisfy these principles, those engaged in them can say to one another that they are cooperating on terms to which they would agree if they were free and equal persons whose relation with respect to one another were fair. They could all view their arrangements as meeting the stipulations which they would acknowledge in an initial situation that embodies widely accepted and reasonable constraints on the choice of principles. The general recognition of this fact would provide the basis for a public acceptance of the corresponding principles of justice. No society can, of course, be a scheme of cooperation which men enter voluntarily in a literal sense; each person finds himself placed at birth in some particular position in some particular society, and the nature of this position materially affects his life prospects. Yet a society satisfying the principles of justice as fairness comes as close as a society can to being a voluntary scheme, for it meets the principles which free and equal persons would assent to under circumstances that are fair.

41. A just society, as conceptualized in the passage, can be best described as:
(1) A Utopia in which everyone is equal and no one enjoys any privilege based on their existing positions and powers.
(2) A hypothetical society in which people agree upon principles of justice which are fair.
(3) A society in which principles of justice are not based on the existing positions and powers of the individuals.
(4) A society in which principles of justice are fair to all.
(5) A hypothetical society in which principles of justice are not based on the existing positions and powers of the individuals.

42. The original agreement or original position in the passage has been used by the author as:
(1) A hypothetical situation conceived to derive principles of justice which are not influenced by position, status and condition of individuals in the society.
(2) A hypothetical situation in which every individual is equal and no individual enjoys any privilege based on the existing positions and powers.
(3) A hypothetical situation to ensure fairness of agreements among individuals in society.
(4) An imagined situation in which principles of justice would have to be fair.
(5) An imagined situation in which fairness is the objective of the principles of justice to ensure that no individual enjoys any privilege based on the existing positions and powers.
43. Which of the following best illustrates the situation that is equivalent to choosing "the principles of justice" behind a "veil of ignorance"?
(1) The principles of justice are chosen by businessmen, who are marooned on an uninhabited island after a shipwreck, but have some possibility of returning.

Directions for Questions 46 to 50: The passage given below is followed by a set of five questions. Choose the most appropriate answer to each question.
Our propensity to look out for regularities, and to impose laws upon nature, leads to the psychological phenomenon of dogmatic thinking or, more generally, dogmatic behaviour: we expect regularities everywhere and attempt to find them even where there are none; events which do not yield to these attempts we are inclined to treat as a kind of ‘background noise‘; and we stick to our expectations even when they are inadequate and we ought to accept defeat. This dogmatism is to some extent necessary. It is demanded by a situation which can only be dealt with by forcing our conjectures upon the world. Moreover, this dogmatism allows us to approach a good theory in stages, by way of approximations: if we accept defeat too easily, we may prevent ourselves from finding that we were very nearly right. It is clear that this dogmatic attitude, which makes us stick to our first impressions, is indicative of a strong belief; while a critical attitude, which is ready to modify its tenets, which admits doubt and demands tests, is indicative of a weaker belief. Now according to Hume‘s theory, and to the popular theory, the strength of a belief should be a product of repetition; thus it should always grow with experience, and always be greater in less primitive persons. But dogmatic thinking, an uncontrolled wish to impose regularities, a manifest pleasure in rites and in repetition as such, is characteristic of primitives and children; and increasing experience and maturity sometimes create an attitude of caution and criticism rather than of dogmatism. My logical criticism of Hume‘s psychological theory, and the considerations connected with it, may seem a little removed from the field of the philosophy of science. But the distinction between dogmatic and critical thinking, or the dogmatic and the critical attitude, brings us right back to our central problem. For the dogmatic attitude is clearly related to the tendency to verify our laws and schemata by seeking to apply them and to confirm them, even to the point of neglecting refutations, whereas the critical attitude is one of readiness to change them - to test them; to refute them; to falsify them, if possible. This suggests that we may identify the critical attitude with the scientific attitude, and the dogmatic attitude with the one which we have described as pseudo-scientific. It further suggests that genetically speaking the pseudo-scientific attitude is more primitive than, and prior to, the scientific attitude: that it is a pre-scientific attitude. And this primitivity or priority also has its logical aspect. For the critical attitude is not so much opposed to the dogmatic attitude as super-imposed upon it: criticism must be directed against existing and influential beliefs in need of critical revision - in other words, dogmatic beliefs. A critical attitude needs for its raw material, as it were, theories or beliefs which are held more or less dogmatically. Thus, science must begin with myths, and with the criticism of myths; neither with the collection of observations, nor with the invention of experiments, but with the critical discussion of myths, and of magical techniques and practices. The scientific tradition is distinguished from the pre-scientific tradition in having two layers. Like the latter, it passes on its theories; but it also passes on a critical attitude towards them. The theories are passed on, not as dogmas, but rather with the challenge to discuss them and improve upon them. The critical attitude, the tradition of free discussion of theories with the aim of discovering their weak spots so that they may be improved upon, is the attitude of reasonableness, of rationality. From the point of view here developed, all laws, all theories, remain essentially tentative, or conjectural, or hypothetical, even when we feel unable to doubt them any longer. Before a theory has been refuted we can never know in what way it may have to be modified.

46. In the context of science, according to the passage, the interaction of dogmatic beliefs and critical attitude can be best described as:
(1) A duel between two warriors in which one has to die.
(2) The effect of a chisel on a marble stone while making a sculpture.
(3) The feedstock (natural gas) in fertilizer industry being transformed into fertilizers.
(4) A predator killing its prey.
(5) The effect of fertilizers on a sapling.

47. According to the passage, the role of a dogmatic attitude or dogmatic behaviour in the development of science is
(1) critical and important, as, without it, initial hypotheses or conjectures can never be made.
(2) positive, as conjectures arising out of our dogmatic attitude become science.
(3) negative, as it leads to pseudo-science.
(4) neutral, as the development of science is essentially because of our critical attitude.
(5) inferior to critical attitude, as a critical attitude leads to the attitude of reasonableness and rationality.

48. Dogmatic behaviour, in this passage, has been associated with primitives and children. Which of the following best describes the reason why the author compares primitives with children?
(1) Primitives are people who are not educated, and hence can be compared with children, who have not yet been through school.
(2) Primitives are people who, though not modern, are as innocent as children.
(3) Primitives are people without a critical attitude, just as children are.
(4) Primitives are people in the early stages of human evolution; similarly, children are in the early stages of their lives.
(5) Primitives are people who are not civilized enough, just as children are not.
49. Which of the following statements best supports the argument in the passage that a critical attitude leads to a weaker belief than a dogmatic attitude does?
(1) A critical attitude implies endless questioning, and, therefore, it cannot lead to strong beliefs.
(2) A critical attitude, by definition, is centred on an analysis of anomalies and “noise”.
(3) A critical attitude leads to questioning everything, and in the process generates “noise” without any conviction.
(4) A critical attitude is antithetical to conviction, which is required for strong beliefs.
(5) A critical attitude leads to questioning and to tentative hypotheses.

50. According to the passage, which of the following statements best describes the difference between science and pseudo-science?
(1) Scientific theories or hypothesis are tentatively true whereas pseudo-sciences are always true.
(2) Scientific laws and theories are permanent and immutable whereas pseudo-sciences are contingent on the prevalent mode of thinking in a society.
(3) Science always allows the possibility of rejecting a theory or hypothesis, whereas pseudo-sciences seek to validate their ideas or theories.
(4) Science focuses on anomalies and exceptions so that fundamental truths can be uncovered, whereas pseudo-sciences focus mainly on general truths.
(5) Science progresses by collection of observations or by experimentation, whereas pseudo-sciences do not worry about observations and experiments.
