In the grading system, A, B, C, D, and F grades fetch 6, 4, 3, 2, and 0 grade points respectively. The Grade Point Average (GPA) is the arithmetic mean of the grade points obtained in the five subjects. For example Nisha’s GPA is (6 + 2 + 4 + 6 + 0) / 5 = 3.6. Some additional facts are also known about the students’ grades. These are (a) Vipul obtained the same grade in Marketing as Aparna obtained in Finance and Strategy. (b) Fazal obtained the same grade in Strategy as Utkarsh did in Marketing. (c) Tara received the same grade in exactly three courses. 1.

What grade did Preeti obtain in Statistics? 1. A 2. B 3. C

Sol. (1) GPA of Preeti = 3.2 F +D+x+D+y = 3.2 i.e. 5 0 + 2 + x + 2 + y = 16 x + y = 12 So only combination possible is A, A. So Preeti obtained A grade in statistics.

2.

In operations, Tara could have received the same grade as

4. D

1. Ismet

2. Hari

3. Jagdeep

4. Manab

Sol. (4) Tara received same grade in 3 courses. We already know that Tara has got B grade in one of the subject and GPA is 2.4. So in 3 courses in which he scored same grade is B. So Tara has received the same grade as Manab.

3.

In Strategy, Gowri’s grade point was higher than that obtained by 1. Fazal 2. Hari 3. Nisha 4. Rahul

Sol. (2)

GPA of Gowri is 3.8 i.e. 3 + 3 + 6 + x + 4 = 3.8 × 5 16 + x = 18 x=2 So in strategy, Gowri’s grade is C. Rahul’s grade in strategy = (4.2 × 5) – 15 = 6, i.e., A. Fazal’s grade in strategy = (2.4 × 5) – 8 = 4, i.e., B. Hence, Gowri’s grade will be higher than that of Hari. 4.

What grade did Utkarsh obtain in Finance? 1. B 2. C 3. D

Sol. (3) As Fazal GPA = 2.4 So D + F + B + P + D = 2.4 × 5 2 + 0 + 4 + P + 2 = 12 P=4 So his grade in strategy is B. So Grade of Utkarsh in marketing is also B. So for Utkarsh, x + B + F + C + A = 3 × 5 x + 4 + 0 + 3 + 6 = 15 x=2 So grade of Utkarsh in finance = D.

Coach John sat with the score cards of Indian players from the 3 games in a one-day cricket tournament where the same set of players played for India and all the major batsmen got out. John summarized the batting performance through three diagrams, one for each games. In each diagram, the three outer triangles communicate the number of runs scored by the three top scores from India, where K, R, S, V, and Y represent Kaif, Rahul, Saurav, Virender, and Yuvraj respectively. The middle triangle in each diagram denotes the percentage of total score that was scored by the top three Indian scorers in that game. No two players score the same number of runs in the same game. John also calculated two batting indices for each player based on his scores in the tournaments; the R-index of a batsman is the difference between his highest and lowest scores in the 3 games while the M-index is the middle number, if his scores are arranged in a non-increasing order.

If f(x) = x3 – 4x + p , and f(0) and f(1) are of opposite sings, then which of the following is necessarily true 1. –1 < p < 2

2. 0 < p < 3

3. –2 < p < 1

4. –3 < p < 0

Sol. (2)

We have f(0) = 03 – 4(0) + p = p f(1) = 13 – 4(1) + p = p – 3 If P and P –3 are of opp. signs then p(p – 3) < 0 Hence 0 < p < 3. 45.

Suppose n is an integer such that the sum of digits on n is 2, and 1010 < n < 10n . The number of different values of n is 1. 11 2. 10 3. 9 4. 8

Sol. (1)

We have (1) 1010 < n < 1011 (2) Sum of the digits for ‘n’ = 2 Clearly– (n)min = 10000000001 (1 followed by 9 zeros and finally 1) Obviously, we can form 10 such numbers by shifting ‘1’ by one place from right to left again and again. Again, there is another possibility for ‘n’ n = 20000000000 So finally : No. of different values for n = 10 + 1 = 11 ans. 46.

A milkman mixes 20 litres of water with 80 litres of milk. After selling one-fourth of this mixture, he adds water to replenish the quantity that he had sold. What is the current proportion of water to milk? 1. 2 : 3 2. 1 : 2 3. 1 : 3 4. 3 : 4

Sol. (1)

The diagram is self explanatory. Removal of 25 litres at stage I will result in volume of milk being reduced by 80% of 25 lit i.e. 20 lit and volume of water being reduced by the remaining 5 lit. So M = 60 lit and W = 15 lit. Addition of 25 lit water will finally given M = 60 lit and W = 40 M. Hence the ratio of W and M = 40 : 60 = 2 : 3. 47.

Karan and Arjun run a 100-meter race, where Karan beats Arjun 10 metres. To do a favour to Arjun, starts 10 metres behind the starting line in a second 100 metre race. They both run at their earlier speeds. Which of the following is true in connection with the second race? 1. Karan and Arjun reach the finishing line simultaneously. 2. Arjun beats Karan by 1 metre 3. Arjun beats Karan by 11 metres. 4. Karan beats Arjun by 1 metre.

Sol. (4)

Situation (I): In whatever time Karan covers a distance of 100 m, Arjun covers 90 m in the same time. Situation (II): Now Karan is 10 m behind the starting point. Once again to cover 100 m from this new point Karan will be taking the same time as before. In this time Arjun will be covering 90 meters only. This means that now both of them will be at the same point, which will be 10 meters away from the finish point. Since both of them are required to cover the same distance of 10 m now and Karan has a higher speed, he will beat Arjun. No need for calculations as option (4) is the only such option. 50.

N persons stand on the circumference of a circle at distinct points. Each possible pair of persons, not standing next to each other, sings a two-minute song one pair after the other. If the total time taken for singing is 28 minutes, what is N? 1. 5 2. 7 3. 9 4. None of the above

Sol. (2)

Each person will form a pair with all other persons except the two beside him. Hence he will form (n – 3) pairs. If we consider each person, total pairs = n (n – 3) but here each pair is counted twice. n(n – 3) Hence actual number of pairs = 2 n(n – 3) × 2 = n(n – 3) min They will sing for 2 Hence n(n –3) = 28 ⇒ n2 – 3n – 28 = 0 ⇒ n = 7 or – 4 Discarding the –ve value: n = 7 51.

In NutsAndBolts factory, one machine produces only nuts at the rate of 100 nuts per minute and needs to be cleaned for 5 minutes after production of every 1000 nuts. Another machine produces only bolts at the rate of 75 bolts per minute and needs to cleaned for10 minutes after production of every 1500 bolts. If both the machines start production at the same time, what is the minimum duration required for producing 9000 pairs of nuts and bolts? 1. 130 minutes 2. 135 minutes 3. 170 minutes 4. 180 minutes

Sol. (3)

Machine I: Number of nuts produced in one minute = 100 To produce 1000 nuts time required = 10 min Cleaning time for nuts = 5 min Over all time to produce 1000 nuts = 15 min. Over all time to produce 9000 = 138 min – 5 min = 133 min … (1) Machine II: To produce 75 bolts time required = 1 min To produce 1500 bolts time required = 20 min Cleaning time for bolts = 10 in. Effective time to produce 1500 bolts = 30 min Effective time to produce 9000 bolts = 30 × 6 – 10 = 170 min … (2) From (1) and (2) Minimum time = 170 minutes 52.

As per the question, we need to satisfy three conditions namely: 1. Adults (A) > Boys (B) 2. Boys (B) > Girls (G) 3. Girls (G) > Families (F) Clearly, if the number of families are 2, maximum number of adults can only be 4. Now, for the second condition to be satisfied, every family should have atleast two boys and one girl each. This will result in non-compliance with the first condition because adults will be equal to boys. If we consider the same conditions for 3 families, then all three conditions will be satisfied. 58.

3. BDECA

4. CEDAB

Sol. (2) B is the opening statement as it introduces the subject and the date. EDA is a sequence that describes the situation from the east to the west. Statement C is a stand-alone statement. 95.

A. He felt justified in bying Congress altogether on a variety of moves. B. At times he was fighting the entire Congress. C. Bush felt he had a mission to restore power to the presidency. D. Bush was not fighting just the democrats. E. Representatives democracy is a messy business, and a CEO of the white House does not like a legislature of second guessers and time wasters. 1. CAEDB

2. DBAEC

3. CEADB

4. ECDBA

Sol. (4) CDBA is a mandatory sequence. “Bush was not fighting just the democrats” in statement D, relates directly with “At times he was fighting…” in statement B. Directions for questions 96 to 97: Four alternative summaries are given below each text. Choose the option that best captures the essence of the text. 96.

The human race is spread all over world, from the polar regions to the tropics. The people of whom it is made up eat different kinds of food, partly according to the climate in which they live, and partly according to the kind of food which their country produces. In hot climates; meat and fat are not much needed; but in the Arctic regions they seem to be very necessary for keeping up the heat of the body. Thus, in India, People live chiefly on different kinds of grains, eggs, milk, or sometimes fish and meat. In Europe people eat more meat and less gain. In the Arctic regions, where no grains and fruits are produced, the Eskimo and others races live almost entirely on meat and fish.

1. Food eaten by people in different regions of the world depends on the climate and produce of the region, and varies from meat and fish in the Arctic to predominantly grains in the tropics. 2. Hot climates require people to eat grains while cold regions require people to eat meat and fish. 3. In hot countries people eat mainly grains while in the Arctic, they eat meat and fish because they cannot grow grains. 4. While people in Arctic regions like meat and fish and those in hot regions like India prefer mainly grains, they have to change what they eat depending on the local climate and the local produce. Sol. (1) Statement 2 is only partially true. It only talks of requirements and not of what grows in those regions. Similarly, statement 3 talks only of produce and not requirement. The age is not concerned with what people like or prefer but with what is locally available or required. 97.

You seemed at first to take no notice of your school-fellows, or rather to set yourself against them because they were strangers to you. They knew as little of you as you did of them; this would have been the reason for their keeping aloof from you as well, which you would have felt as a hardship. Learn never to conceive a prejudice

against others because you know nothing of them. It is bad reasoning, and makes enemies of half the world. Do not think ill of them till they behave ill to you; and then strive to avoid the faults, which you see in them. This will disarm their hostility sooner than pique or resentment or complaint. 1. The discomfort you felt with your school fellows was because both sides knew little of each other. You should not complain unless you find others prejudiced against you and have attempted to carefully analyze the faults you have observed in them. 2. The discomfort you felt with your school fellows was because both sides knew little of each other. Avoid prejudice and negative thoughts till you encounter bad behaviour from others, and then win them over by shunning the faults you have observed. 3. You encountered hardship amongst your school fellows because you did not know then well. You should learn not to make enemies because of your prejudices irrespective of their behaviour towards you. 4. You encountered hardship amongst your school fellows because you did not know them well. You should learn to not make enemies because of your prejudices unless they behave badly with you. Sol. (2) The last sentence of the age is only conveyed fully in option (2). Directions for questions 98 to 118: Each of the five ages given below is followed by a set of questions. Choose the best answer to each question. AGE I The painter is now free …..they served so sincerely. 98.

When a culture is insecure, the painter chooses his subject on the basis of: 1. 2. 3. 4.

The prevalent style in the society of his time. Its meaningfulness to the painter. What is put in front of the easel. Past experience and memory of the painter

Sol. (1) The confusion could be between answer choices 1 and 2. However, answer choice 2 deals with what the author feels about the subject of a painting, whereas we are concerned about a painter and an insecure culture. The second line of the last paragraph confirms the answer choice 1. 99.

In the sentence, “I believe there is a connection” (second paragraph), what two developments is the author referring to? 1. 2. 3. 4.

Painters using a dying hero and using a fruit as a subject of painting. Growing success of painters and an increase in abstract forms. Artists gaining freedom to choose subjects and abandoning subjects altogether. Rise of Impressionists and an increase in abstract forms.

Sol. (3) Reading the first and the second paragraph quite easily takes us to the answer choice 3. 100.

Which of the following is NOT necessarily among the attributes needed for a painter to succeed: 1. The painter and his public agree on what is significant.

2. The painting is able to communicate and justify the significance of its subject selection. 3. The subject has a personal meaning for the painter. 4. The painting of subjects is inspired by historical developments. Sol. (3) The second sentence of the fifth paragraph says ‘the subject may have a personal meaning … ; but there … general meaning.’ This is quite the opposite of what answer choice 3 states, and so it becomes the answer. 101.

In the context of the age, which of the following statements would NOT be true? 1. 2. 3. 4.

Painters decided subjects based on what they ed from their own lives. Painters of reeds and water in China faced no serious problem of choosing a subject. The choice of subject was a source of scandals in nineteenth century European art. Agreement on the general meaning of a painting is influenced by culture and historical context.

Sol. (1) The third paragraph, second line says ‘a subject does not start … or with something which the painter has to ’. 102.

Which of the following views is taken by the author? 1. 2. 3. 4.

The The The The

more more more more

insecure secure a secure a insecure

a culture, the greater the freedom of the artist. culture, the greater the freedom of the artist. culture, more difficult the choice of subject. a culture, the less significant the choice of the subject.

Sol. (1) Refer to the second-last paragraph, first line. AGE II Recently I spent several hours … most of their factories. 103.

According to the age, which of the following statements is true? 1. 2. 3. 4.

Executives of automobile companies are inefficient and ludicrous. The speed at which an automobile is driven in a city has not changed much in a century. Anthropological factors have fostered innovation in automobiles by promoting use of new technologies. Further innovation in jet engines has been more than incremental.

Sol. (2) Quite a direct answer, refer to the fourth paragraph. 104.

Which of the following views does the author fully in the age? 1. 2. 3. 4.

Nothing is as permanent as change. Change is always rapid. More money spent on innovation leads to more rapid change. Over decades, structural change has been incremental.

Sol. (4) Refer to the sixth paragraph.

105.

Which of the following best describes one of the main ideas discussed in the age? 1. 2. 3. 4.

Rapid change is usually welcomed in society. Industry is not as innovative as it is made out to be. We should have less change than what we have now. Competition spurs companies into radical innovation.

Sol. (2) This is a main idea question; if you look at the complete age, the author through examples of aeroplanes and cars and even telephones etc. is trying to show that innovation has not happened as much as it has been made out to be. The changes have been basically incremental and cosmetic. 106.

According to the age, the reason why we continues to be dependent on fossil fuels is that: 1. 2. 3. 4.

Auto executives did not wish to change. No alternative fuels were discovered. Change in technology was not easily possible German, Japanese and French companies could not come up with new technologies.

Sol. (1) Refer to the last two lines of the last paragraph. AGE III The viability of the … professional elites. 107.

According to the author, the British policy during the ‘New Imperialism’ period tended to be defensive because 1. 2. 3. 4.

it was unable to deal with the fallouts of a sharp increase in capital. its cumulative capital had undesirable side-effects. its policies favoured developing the vast hinterland. it prevented the growth of a set-up which could have been capitalistic in nature.

Sol. (1) The answer is clearly stated in the fifth line. 108.

Under New Mercantilism, the fervent nationalism of the native middle classes does not create conflict with the multinational corporations because they (the middle classes) 1. 2. 3. 4.

negotiate with the multinational corporations are dependent on the international system for their continued prosperity. are not in a position to challenge the status quo. do not enjoy popular .

Sol. (3) The second-last paragraph talks of the various factors that are responsible for this. Answer choice 3 combines all of them.

109.

In the sentence, “They are prisoners of the taste patterns and consumption standards set at the center.” (fourth paragraph), what is the meaning of ‘centre’? 1. 2. 3. 4.

National government Native capitalists. New capitalists. None of the above.

Sol. (4) The centre as can be seen from the first paragraph is the - `rival centers of capital on the Continent and in America,’ therefore none of these is the answer. 110.

The author is in a position to draw parallels between New Imperialism and New Mercantilism because 1. both originated in the developed Western capitalist countries. 2. New Mercantilism was a logical sequel to New Imperialism 3. they create the same set outputs – a labour force, middle classes and rival centers of capital. 4. both have comparable uneven and divisive effects.

Sol. (4) The answer can be figured out from the first and the third paragraph. AGE IV Fifty feet away … mystery to science. 111.

The book Man-Eaters of Tsavo annoys some scientists because 1. 2. 3. 4.

it revealed that Tsavo lions are ferocious. Patterson made a helluva lot of money from the book by sensationalism. it perpetuated the bad name Tsavo lions had. it narrated how two male Tsavo lions were killed.

Sol. (3) Refer to the third paragraph, last three lines. 112.

The sentence which concludes the first paragraph, “Now they knew better”, implies that: 1. The two scientists were struck by wonder on seeing maneless lions for the first time. 2. Though Craig was an expert on the Serengeti lion, now he also knew about the Tsavo lions. 3. Earlier, Craig and West thought that amateur observers had been mistaken. 4. Craig was now able to confirm that darkening of the noses as lions aged applied to Tsavo lions as well.

Sol. (3) Refer to the first paragraph, second-last line.

113.

According to the age, which of the following has NOT contributed to the popular image of Tsavo lions as savage creatures? 1. Tsavo lions have been observed to bring down one of the strongest and most aggressive animals — the Cape buffalo. 2. In contrast to the situation in traditional lion haunts, scarcity of non-buffalo prey in the Tsavo makes the Tsavo lions more aggressive. 3. The Tsavo lion is considered to be less evolved than the Serengeti variety. 4. Tsavo lions have been observed to attack vehicles as well as humans.

Sol. (3) All the other three answer choices are in the fourth and fifth paragraphs. 114.

Which of the following, if true, would weaken the hypothesis advanced by Gnoske and Peterhans most? 1. Craig and Peyton develop even more serious doubts about the idea that Tsavo lions are primitive. 2. The maneless Tsavo East lions are shown to be closer to the cave lions. 3. Pleistocene cave lions are shown to be far less violent than believed. 4. The morphological variations in body and skull size between the cave and Tsavo lions are found to be insignificant.

Sol. (3) If 3 is true and if Tsavo lions are similar to the cave lions, then the Tsavo lions should also be less violent, whereas the hypothesis tries to give reasons for the Tsavo lions being more ferocious. AGE V Throughout human history … health of the nation. 115.

The author recommends micronutrient-repletion for large-scale treatment of chronic degenerative diseases because 1. 2. 3. 4.

it is relatively easy to manage. micronutrient deficiency is the cause of these diseases. it can overcome genetic risk factors. it can compensate for other lifestyle factors.

Sol. (2) Refer to the fourth paragraph, first line. 116.

Tailoring micronutrient-based treatment plans to suit individual deficiency profiles is not necessary because 1. 2. 3. 4.

it very likely to give inconsistent or negative results. it is a classic pharmaceutical approach not suited to micronutrients. most people are consuming suboptimal amounts of safe-to-consume micronutrients. it is not cost effective to do so.

Sol. (3) Refer to the fourth paragraph, third-last line.

117.

Type-B malnutrition is a serious concern in developed countries because 1. 2. 3. 4.

developing countries mainly suffer from Type-A malnutrition. it is a major contributor to illness and death. pharmaceutical companies are not producing drugs to treat this condition. national surveys on malnutrition do not include newer micronutrient groups.

Sol. (2) The fourth paragraph, first line says Type B malnutrition is the major cause of chronic degenerative diseases. The first paragraph says chronic degenerative diseases are the major causes of ill-health and death, hence answer choice 2 follows. 118.

Why are a large number of apparently healthy people deemed pre-ill? 1. 2. 3. 4.

They may have chronic degenerative diseases. They do not know their own genetic risk factors which predispose them to diseases. They suffer from Type-B malnutrition. There is a lengthy latency period associated with chronically degenerative diseases.

Sol. (1) Check the first paragraph for the answer. Sub section III-B: Number of Questions = 5 Note: Questions 119 to 123 carry two marks each. Directions for Questions 119 and 120: The sentences given in each question, when properly sequenced, form a coherent paragraph. Each sentence is labeled with a letter. Choose the most logical order of sentences from among the given choices to construct a coherent paragraph. 119.

A. But this does not mean that death was the Egyptians’ only preoccupation. B. Even papyri come mainly from pyramid temples. C. Most of our traditional sources of information about the Old Kingdom are monuments of the rich like pyramids and tombs. D. Houses in which ordinary Egyptian lived have not been preserved, and when most people died they were buried in simple graves. E. We know infinitely more about the wealthy people of Egypt than we do about the ordinary people, as most monuments were made for the rich. 1. CDBEA

2. ECDAB

3. EDCBA

4. DECAB

Sol. (3) Both statements C and B (papyri is the plural for Egyptian papers and documents) are talking about sources of information. That is why CB is a mandatory pair. 120.

A. Experts such as Larry Burns, head of research at GM, reckon that only such a full hearted leap will allow the world to cope with the mass motorization that will one day come to China or India. B. But once hydrogen is being produced from biomass or extracted from underground coal or made from water, using nuclear or renewable electricity, the way will be open for a huge reduction in carbon emissions from the whole system. C. In theory, once all the bugs have been sorted out, fuel cells should deliver better total fuel economy than any existing engines. D. That is twice as good as the internal combustion engine, but only five percentage points better than a diesel hybrid. E. Allowing for the resources needed to extract hydrogen from hydrocarbon, oil coal or gas, the fuel cell has an efficiency of 30%.

1. CEDBA

2. CEBDA

3. AEDBC

4. ACEBD

Sol. (1) ED is a mandatory pair as ‘the fuel cell efficiency has an efficiency of 30%’ in E connects with ‘That is twice as good’ in D. BA is a pair because ‘the way will be open for a huge reduction…’ in B connects with ‘only such a full-hearted leap will allow the world to cope with mass motorization’ in A. Directions for Questions 121 to 123: Four alternative summaries are given below each text. Choose the option that best captures the essence of the text. 121.

Local communities have often come in conflict with agents trying to exploit resources, at a faster pace, for an expanding commercial-industrial economy. More often than not, such agents of resource-intensification are given preferential treatment by the state, through the grant of generous long leases over mineral or fish stocks, for example, or the provision of raw material at an enormously subsidized price. With the injustice so compounded, local communities at the receiving end of this process have no recourse expect direct action, resisting both the state and outside exploiters through a variety of protest techniques. These struggles might perhaps be seen as a manifestation of a new kind of class conflict. 1. A new kind of class conflict arises from preferential treatments given to agents of resource-intensification by the state, which the local community sees as unfair. 2. The grant of long leases to agents of resource-intensification for an expanding commercial-industrial economy leads to direct protests from the local community, which sees it as unfair. 3. Preferential treatment given by the state to agents of resource-intensification for an expanding commercial-industrial economy exacerbates injustice to local communities and leads to direct protests from them, resulting in a new type of class conflict. 4. Local communities have no option but to protest against agents of resourceintensification and create a new type of class conflict when they are given raw material at subsidized prices for an expanding commercial-industrial economy.

Sol. (3) Statements 2 and 4 are partially true, as they do not cover all the examples of preferential treatment. Statement 1 is incomplete, as it does not mention direct protest. 122.

Although almost all climate scientists agree that the Earth is gradually warming, they have long been of two minds about the process of rapid climate shifts within larger periods of change. Some have speculated that the process works like a giant oven or freezer, warming or cooling the whole planet at the same time. Others think that shifts occur on opposing schedules in the Northern and Southern Hemisphere, like exaggerated seasons. Recent research in examining climate patterns in the Southern Hemisphere at the end of the last Ice Age strengthens the idea that warming and cooling occurs at alternate times in the two hemispheres. A more definitive answer to this debate will allow scientists to better predict when and how quickly the next climate shift will happen. 1. Scientists have been unsure whether rapid shifts in the Earth’s climate happen all at once or on opposing schedules in different hemispheres; research will help find a definitive answer and better predict climate shifts in future. 2. Scientists have been unsure whether rapid shifts in the Earth’s climate happen all at once or on opposing schedules in different hemispheres; finding a definitive answer will help them better predict climate shifts in future. 3. Research in will help scientists find a definitive answer about warming and cooling of the Earth and predict climate shifts in the future in a better manner.

4. More research rather than debates on warming or cooling of the Earth and exaggerated seasons in its hemisphere will help scientists in predict changes better in future. Sol. (2) Statement 3 is factually wrong as we don’t know if further research can happen only in . Option 4 wrongly brings out a contest between research and debate. Between options 1 and 2, choice 1 is inappropriate because we don’t know if ‘research’ will help find a ‘definitive answer’. 123.

Modern bourgeois society, said Nietzsche, was decadent and enfeebled – a victim of the excessive development of the rational faculties at the expense of will and instinct. Against the liberal-rationalist stress on the intellect, Nietzsche urged recognition of the dark mysterious world of instinctual desires – the true forces of life. Smother the will excessive intellectualizing and you destroy the spontaneity that sparks cultural creativity and ignites a zest for living. The critical and theoretical outlook destroyed the creative instincts. For man’s manifold potential to be realized, he must forego relying on the intellect and nurture again the instinctual roots of human existence. 1. Nietzsche urges the decadent and enfeebled modern society to forego intellect and give importance to creative instincts. 2. Nietzsche urges the decadent and enfeebled modern society to smother the will with excessive intellectualizing and ignite a zest for living. 3. Nietzsche criticizes the intellectuals for enfeebling the modern bourgeois society by not nurturing man’s creative instincts. 4. Nietzsche blames excessive intellectualization for the decline of modern society and suggests nurturing creative instincts instead.

123. (1) Option 2 is factually wrong. Option 3 is wrong because Nietzsche does not criticize ‘intellectuals’. Option 4 is wrong because he does not talk of ‘the decline of modern society’.
