DIRECTIONS for the question:
The given sentence is missing in the paragraph below. Decide where it best fits among the options 1, 2, 3, or 4 indicated in the paragraph.
Sentence: "Everything is old-world, traditional techniques from Mexico," Ava emphasizes.
Paragraph: The sisters embrace the ways their great-grandfather built and repaired instruments. ____(1) ____. When crafting a Mexican guitarrón used in mariachi music, they use tacote wood for the top of the instrument. Once the wood is cut, they carve the neck and heel from a single block using tools like hand saws, chisels and sandpaper rather than modern power tools — and believe that this traditional method improves the tone of the instrument. ____(2) ____. Their store has a three-year waitlist for instruments that take months to create. ____(3) ____. The family's artisanship has attracted stars like Los Lobos, who own custom guitars made by all three generations of the Delgado family. ____(4) ____. For the sisters, involvement in the family business started at an early age. They each built their first instruments at age 9.
- AOption 3
- BOption 2
- COption 4
- DOption 1
Answer and solution
Answer: (D) Option 1
The sentence is Ava's quote summing up the family's method: everything is done with old-world, traditional techniques from Mexico.
The paragraph opens by saying the sisters embrace the ways their great-grandfather built and repaired instruments. Blank 1 comes right after this general claim and right before the concrete details: tacote wood for the top of the guitarrón, and the neck and heel carved from a single block with hand saws, chisels and sandpaper instead of power tools. The quote belongs here, voicing the general claim before the examples bear it out.
Blank 2 (option B) is the strongest rival, because it follows the description of the techniques. But by then the paragraph has already finished that point with the claim that the traditional method improves the tone, and the next sentence turns to the three-year waitlist. A summing-up quote there would repeat the idea instead of introducing it.
Blanks 3 and 4 (options A and C) sit among sentences about the waitlist, famous clients such as Los Lobos and the sisters' childhood, which have nothing to do with technique.
Hence, option D (Option 1).

The passage given below is followed by four summaries. Choose the option that best captures the essence of the passage.
In the dynamic realm of creativity, artists often find themselves at the crossroads between drawing inspiration from diverse cultures and inadvertently crossing into the territory of cultural appropriation. Inspiration is the lifeblood of creativity, driving artists to create works that resonate across borders. The globalized nature of the modern world invites artists to draw from a vast array of cultural influences. When approached respectfully, inspiration becomes a bridge, fostering understanding and appreciation of cultural diversity. However, the line between inspiration and cultural appropriation can be thin and easily blurred. Cultural appropriation occurs when elements from a particular culture are borrowed without proper understanding, respect, or acknowledgment. This leads to the commodification of sacred symbols, the reinforcement of stereotypes, and the erasure of the cultural context from which these elements originated. It’s essential to recognize that the impact of cultural appropriation extends beyond the realm of artistic expression, influencing societal perceptions and perpetuating power imbalances.
- AIn today’s world of creativity, artists have to decide between respectfully acknowledging works that are inspired by diverse cultures and appropriating elements without respect for their contexts.
- BArtists must navigate the thin line between inspiration and cultural appropriation, where respectful inspiration fosters cultural understanding whereas appropriation involves borrowing without acknowledgement leading to commodification and reinforcement of stereotypes.
- CArtists in a globalised world must navigate between drawing inspiration from diverse cultures respectfully and cultural appropriation that involves borrowing without proper acknowledgement which has broader societal impacts including perpetuating power imbalances.
- DIn a globalised world, artists must draw from diverse cultural influences to create works that appeal to all, and this results in instances of both inspiration and cultural appropriation.
Answer and solution
Answer: (C) Artists in a globalised world must navigate between drawing inspiration from diverse cultures respectfully and cultural appropriation that involves borrowing without proper acknowledgement which has broader societal impacts including perpetuating power imbalances.
The passage makes three points. In a globalised world, artists draw on many cultures. Respectful inspiration builds understanding, but the line between inspiration and appropriation is thin. Appropriation, which is borrowing without understanding, respect or acknowledgement, harms more than art: it commodifies sacred symbols, reinforces stereotypes and perpetuates power imbalances in society.
Option C keeps all of this: the globalised setting, the need to navigate between respectful inspiration and appropriation, appropriation as borrowing without acknowledgement, and its broader societal impact, including power imbalances.
Option B is the strongest rival. It captures the thin line and names commodification and stereotypes, but it drops the globalised setting and, more importantly, the closing point that the harm reaches beyond art into society and power imbalances.
Option A misstates the choice as one between acknowledging 'works' and appropriating. Option D says artists must draw on other cultures to appeal to all, which the passage never claims, and it drops the harms of appropriation.
Hence, option C (Artists in a globalised world must navigate between drawing inspiration from diverse cultures respectfully and cultural appropriation that involves borrowing without proper acknowledgement which has broader societal impacts including perpetuating power imbalances.).

DIRECTIONS for the question:
The passage given below is followed by four summaries. Choose the option that best captures the essence of the passage.
Zombie cells may contribute to age-related chronic inflammation: this finding could help scientists understand more about the aging process and why the immune system becomes less effective as we get older. Zombie or “senescent” cells are damaged cells that can no longer divide and grow like normal cells. Scientists think that these cells can contribute to chronic health problems when they accumulate in the body. In younger people, the immune system is more effective at clearing senescent cells from the body through a process called apoptosis, but as we age this process becomes less efficient. As a result, there is an accumulation of senescent cells in different organs in the body, either through increased production or reduced clearance by the immune system. The zombie cells continue to use energy though they do not divide, and often secrete chemicals that cause inflammation, which if persistent for longer periods of time can damage healthy cells leading to chronic diseases.
- AA younger person’s immune system is healthy and is able to clear the damaged cells, but as people age, the zombie cells resist apoptosis, and start accumulating in the body.
- BAging leads to less effective apoptosis, and therefore zombie cells start to accumulate in the body, causing inflammation, which accelerates aging and leads to chronic diseases.
- CSenescent “zombie” cells are inactive or malfunctioning cells that can be found throughout the body.
- DDead cells accelerate chronic inflammation weakening the immune system and lead to aging.
Answer and solution
Answer: (B) Aging leads to less effective apoptosis, and therefore zombie cells start to accumulate in the body, causing inflammation, which accelerates aging and leads to chronic diseases.
The passage describes a chain of cause and effect. Senescent 'zombie' cells cannot divide. In young people the immune system clears them by apoptosis, but with age this clearance becomes less efficient, so the cells accumulate. They keep using energy and secrete chemicals that cause inflammation, and persistent inflammation damages healthy cells and leads to chronic disease.
Option B follows this chain from start to finish: aging weakens apoptosis, zombie cells accumulate, they cause inflammation, and this leads to chronic diseases.
Option A is the strongest rival, since it too contrasts young and old immune systems. But it says the cells 'resist apoptosis', whereas the passage says the immune system's clearance becomes less efficient. It also stops at accumulation and leaves out inflammation and chronic disease, the passage's main point.
Option C is only a definition of the cells. Option D calls them dead cells, though the passage says they keep using energy, and it reverses the order of cause by making inflammation weaken the immune system.
Hence, option B (Aging leads to less effective apoptosis, and therefore zombie cells start to accumulate in the body, causing inflammation, which accelerates aging and leads to chronic diseases.).

Five jumbled sentences (labelled 1, 2, 3, 4, and 5), related to a topic, are given below. Four of them can be put together to form a coherent paragraph. Identify the odd sentence out and key in the number of that sentence as your answer.
1. The Bayeux tapestry was, therefore, an obvious way to tell people about the downfall of the English and the rise of the Normans.
2. So if we take expert in Anglo-Saxon culture Gale Owen-Crocker’s idea that the tapestry was originally hung in a square with certain scenes facing each other, people would have stood in the centre.
3. Art historian Linda Neagley has argued that pre-Renaissance people interacted with art visually, kinaesthetically (sensory perception through bodily movement) and physically.
4. That would make it an 11th-century immersive space with scenes corresponding and echoing each other, drawing the viewer’s attention, playing on their senses and understanding of the story they thought they knew.
5. The Bayeux tapestry would have been hung at eye level to enable this.
Type in your answer (TITA). No negative mark for a wrong answer.
Answer and solution
Answer: 1
Sentences 3, 5, 2 and 4 form a chain about how the Bayeux tapestry was experienced.
Sentence 3 gives Linda Neagley's claim that pre-Renaissance people engaged with art visually, kinaesthetically and physically. Sentence 5 applies it: the tapestry would have been hung at eye level 'to enable this'. Sentence 2 adds Gale Owen-Crocker's idea that it hung in a square, so people 'would have stood in the centre'. Sentence 4 draws the result: 'That would make it' an immersive 11th-century space where scenes echo each other and play on the viewer's senses.
Sentence 1 does not belong. It concludes, with 'therefore', that the tapestry was an obvious way to tell people about the downfall of the English and the rise of the Normans. That is a point about the tapestry's political message, while the other four sentences are about how it was hung and physically experienced. Nothing in them leads to that 'therefore'.
The answer is 1.

DIRECTIONS for the question:
Five jumbled sentences (labelled 1, 2, 3, 4, and 5), related to a topic, are given below. Four of them can be put together to form a coherent paragraph. Identify the odd sentence out and key in the number of that sentence as your answer.
1. Developments both technological and sociocultural have afforded us far greater freedom over death than we had in the past, and while we are still adapting ourselves to that freedom, we now appreciate the moral importance of this freedom.
2. But I believe that a type of freedom we can call freedom over death – that is, a freedom in which we shape the timing and circumstances of how we die – should be central to this conversation.
3. Legalising assisted dying is but a further step in realising this freedom over death.
4. Many people endorse, through their opinions or their choices, our freedom over death encompassing a right to medical assistance in hastening our deaths.
5. Freedom is a notoriously complex and contested philosophical notion, and I won’t pretend to settle any of the big controversies it raises.
Type in your answer (TITA). No negative mark for a wrong answer.
Answer and solution
Answer: 4
Sentences 5, 2, 1 and 3 form the author's argument.
Sentence 5 admits that freedom is a complex, contested notion the author will not try to settle. Sentence 2 turns with 'But I believe' to one kind of freedom, freedom over death, which means shaping the timing and circumstances of how we die. Sentence 1 says technological and sociocultural developments have given us far more of this freedom, and that we now appreciate its moral importance. Sentence 3 concludes that legalising assisted dying is 'but a further step in realising this freedom over death'.
Sentence 4 is the odd one out. It reports what many people endorse, through their opinions or choices, about a right to medical help in hastening death. The other four sentences are the author's own philosophical reasoning, moving from the concept to its growth to the conclusion about assisted dying. A report of public opinion is not a step in that reasoning, and sentence 3 already makes the link to assisted dying on its own.
The answer is 4.
Reading passage
Passage for questions 6–9
DIRECTIONS for the passage:
How can we know what someone else is thinking or feeling, let alone prove it in court? In his 1863 book, A General View of the Criminal Law of England, James Fitzjames Stephen, among the most celebrated legal thinkers of his generation, was of the opinion that the assessment of a persons mental state was an inference made with little consciousness. In a criminal case, jurors, doctors, and lawyers could watch defendants—scrutinizing clothing, mannerisms, tone of voicebut the best they could hope for were clues. . . . Rounding these clues up to a judgment about a defendants guilt, or a defendants life, was an act of empathy and imagination. . . . The closer the resemblance between defendants and their judges, the easier it was to overlook the gap that inference filled. Conversely, when a defendant struck officials as unlike themselves, whether by dint of disease, gender, confession, or race, the precariousness of judgments about mental state was exposed.
In the nineteenth century, physicians who specialized in the study of madness and the care of the insane held themselves out as experts in the new field of mental science. Often called alienists or mad doctors, they were the predecessors of modern psychiatrists, neurologists, and psychologists. . . . The opinions of family and neighbors had once been sufficient to sift the sane from the insane, but a growing belief that insanity was a subtle condition that required expert, medical diagnosis pushed physicians into the witness box. . . . Lawyers for both prosecution and defense began to recruit alienists to assess defendants sanity and to testify to it in court.
Irresponsibility and insanity were not identical, however. Criminal responsibility was a legal concept and not, fundamentally, a medical one. Stephen explained: The question What are the mental elements of responsibility? is, and must be, a legal question. It cannot be anything else, for the meaning of responsibility is liability to punishment. . . . Nonetheless, medical and legal accounts of what it meant to be mentally sound became entangled and mutually referential throughout the nineteenth century. Lawyers relied on medical knowledge to inform their opinions and arguments about the sanity of their clients. Doctors commented on the legal responsibility of their patients. Ultimately, the fields of criminal law and mental science were both invested in constructing an image of the broken and damaged psyche that could be contrasted with the whole and healthy one. This shared interest, and the shared space of the criminal courtroom, made it nearly impossible to consider responsibility without medicine, or insanity without law. . . .
Physicians and lawyers shared more than just concern for the mind. Class, race, and gender bound these middle-class, white, professional men together, as did family ties, patriotism, Protestantism, business ventures, the alumni networks of elite schools and universities, and structures of political patronage. But for all their affinities, men of medicine and law were divided by contests over the borders of criminal responsibility, as much within each profession as between them. Alienists steadily pushed the boundaries of their field, developing increasingly complex and capacious definitions of insanity. Eccentricity and aggression came to be classified as symptoms of mental disease, at least by some.
Q6MCQReading Comprehension
The last paragraph of the passage refers to “middle-class, white, professional men”. Which one of the following qualities best describes the connection among them?
- AThe borders of criminal responsibility.
- BEccentricity and aggression.
- CEmpathy and imagination.
- DThe opinions of family and neighbours.
Answer and solution
Answer: (A) The borders of criminal responsibility.
The last paragraph says physicians and lawyers shared more than concern for the mind: class, race, gender, family ties, patriotism, Protestantism, business ventures, elite schools and political patronage bound them together. It then adds that, for all these affinities, they were 'divided by contests over the borders of criminal responsibility', within and between the two professions.
Of the options, only the borders of criminal responsibility is something these men were jointly engaged with. It was the common ground on which both professions met and competed, which is why disputes over it could divide them at all. So it best describes what connected them.
Option B, eccentricity and aggression, is the strongest distractor because it also appears in the last paragraph, but there it names symptoms that some alienists classed as mental disease, not a link between the professions. Option C, empathy and imagination, is how judgments about a defendant's mind were made, in the first paragraph. Option D, the opinions of family and neighbours, is the older way of sorting the sane from the insane that expert doctors replaced.
Hence, option A (The borders of criminal responsibility.).
Q7MCQReading Comprehension
Study the following sets of concepts and identify the set that is conceptually closest to the concerns and arguments of the passage.
- AJudgement, Belief, Accounts, Patronage.
- BEmpathy, Prosecution, Knowledge, Business.
- CJudgement, Insanity, Punishment, Responsibility.
- DAssessment, Empathy, Prosecution, Patriotism.
Answer and solution
Answer: (C) Judgement, Insanity, Punishment, Responsibility.
The passage is about how courts judge a defendant's state of mind, how physicians who studied insanity entered the courtroom, and how the legal idea of criminal responsibility, which Stephen defines as 'liability to punishment', became entangled with medical ideas of insanity.
Option C matches these concerns term by term. Judgement: the opening discusses how judgments about mental state are inferences made through empathy and imagination. Insanity: alienists diagnosed it and testified to it, and kept widening its definition. Punishment: responsibility means 'liability to punishment'. Responsibility: criminal responsibility, and the contests over its borders, run through the whole passage.
Option A is the strongest distractor because it starts with 'Judgement'. But 'Belief', 'Accounts' and 'Patronage' are minor words in the passage; patronage appears only in a list of social ties. Option B mixes one relevant idea (empathy) with passing ones (prosecution, knowledge, business). Option D likewise pairs assessment and empathy with prosecution and patriotism, which are marginal.
Hence, option C (Judgement, Insanity, Punishment, Responsibility.).
Q8MCQReading Comprehension
According to the passage, who or what was an “alienist”?
- AProfessionals who pushed the boundaries of their fields till they became unrecognisable in the nineteenth century.
- BPhysicians and lawyers who were responsible for the condition of immigrants or ‘aliens’ in the nineteenth century.
- CPhysicians and lawyers who were responsible for examining accounts of extraterrestrials or ‘aliens’ in the nineteenth century.
- DPhysicians who specialised in the study of madness and the care of the insane in the nineteenth century.
Answer and solution
Answer: (D) Physicians who specialised in the study of madness and the care of the insane in the nineteenth century.
The second paragraph defines the term directly. In the nineteenth century, 'physicians who specialized in the study of madness and the care of the insane' held themselves out as experts in mental science, and they were 'often called alienists or mad doctors'. They were the predecessors of modern psychiatrists, neurologists and psychologists. Option D restates this definition.
Option A is the strongest distractor, because the last paragraph does say that alienists 'steadily pushed the boundaries of their field'. But that describes something alienists did, not who they were, and the passage never says their field became unrecognisable.
Options B and C read 'alien' in its modern sense of immigrant or extraterrestrial. The passage gives no such meaning, and alienists were physicians, not physicians and lawyers.
Hence, option D (Physicians who specialised in the study of madness and the care of the insane in the nineteenth century.).
Q9MCQReading Comprehension
“Conversely, when a defendant struck officials as unlike themselves, whether by dint of disease, gender, confession, or race, the precariousness of judgments about mental state was exposed.” Which one of the following best describes the use of the word “confession” in this sentence?
- AReferring to the gender, race or disease claimed as a defence by the defendant, here it is a synonym for ‘professing’ a gender, race, or disease.
- BReferring to the practice of ‘confession’ in some faiths, here it is a metaphor for the religion of the defendant.
- CThe defendants struck out at the officials and then confessed to the act.
- DReferring to the defendant’s confession of his or her crime as false, because ‘dint’ is an archaic form of ‘didn’t’ or ‘did not’.
Answer and solution
Answer: (B) Referring to the practice of ‘confession’ in some faiths, here it is a metaphor for the religion of the defendant.
In the sentence, 'confession' is listed with disease, gender and race as things that could make a defendant seem unlike the officials judging him or her. All four are features of who a person is, so 'confession' here is not an admission of guilt. It carries its older sense of a religious creed, as in 'the Protestant confession', a sense that comes from the practice of confession in some faiths. The last paragraph supports this: the officials were bound together by Protestantism, among other ties, so a defendant of another faith would strike them as different.
Option A is the strongest distractor, as it also reads 'confession' as professing something. But it makes the word mean professing a gender, race or disease as a defence, which merges it with the other items instead of adding a separate category.
Option C misreads 'struck' as a physical blow. Option D invents a false origin for 'dint': 'by dint of' means 'by means of', not 'did not'.
Hence, option B (Referring to the practice of ‘confession’ in some faiths, here it is a metaphor for the religion of the defendant.).
Reading passage
Passage for questions 10–13
DIRECTIONS for the passage:
Studies showing that income inequality plays a positive role in economic growth are largely based on three arguments. The first argument focuses on investment indivisibilities wherein large sunk costs are required when implementing new fundamental innovations. Without stock markets and financial institutions to mobilize large sums of money, a high concentration of wealth is needed for individuals to undertake new industrial activities accompanied by high sunk costs . . . [One study] shows the relation between economic growth and income inequality for 45 countries during 1966-1995. [It was found] that the increase in income inequality has a significant positive relationship with economic growth in the short and medium term. Using system GMM, [another study estimated] the relation between income inequality and economic growth for 106 countries during 1965 2005 period. The results show that income inequality has a positive impact on economic growth in the short run, but the two are negatively correlated in the long run. The second argument is related to moral hazard and incentives . . . Because economic performance is determined by the unobservable level of effort that agents make, paying compensations without taking into account the economic performance achieved by individual agents will fail to elicit optimum effort from the agents. Thus, certain income inequalities contribute to growth by enhancing worker motivation . . . and by giving motivation to innovators and entrepreneurs . . . Finally, [another study] point[s] out that the concentration of wealth or stock ownership in relation to corporate governance contributes to growth. If stock ownership is distributed and owned by a large number of shareholders, it is not easy to make quick decisions due to the conflicting interests among shareholders, and this may also cause a free-rider problem in terms of monitoring and supervising managers and workers. . . .
Various studies have examined the relationships between income inequality and economic growth, and most of these assert that a negative correlation exists between the two. . . . Analyzing 159 countries for 19802012, they conclude that there exists a negative relation between income inequality and economic growth; when the income share of the richest 20% of population increases by 1%, the GDP decreases by 0.08%, whereas when the income share of the poorest 20% of population increases by 1%, the GDP increases by 0.38%. Some studies find that inequality has a negative impact on growth due to poor human capital accumulation and low fertility rates . . . while [others] point out that inequality creates political instability, resulting in lower investment. . . . [Some economists] argue that widening income inequality has a negative impact on economic growth because it negatively affects social consensus or social capital formation. One important research topic is the correlation between democratization and income redistribution. [Some scholars] explain that social pressure for income redistribution rises as income inequality increases in a democratic society. In other words, when democratization extends suffrage to a wider class of people, the increased political power of low- and middle-income voters results in broader support for income redistribution and social welfare expansion. However . . . if the rich have more political influence than the poor, the democratic system actually worsens income inequality rather than improving it.
Q10MCQReading Comprehension
According to the incentive or moral hazard argument, which one of the designs below is most consistent with the claim that some inequality can raise growth?
- AA regime that concentrates stock ownership in relation to corporate governance.
- BWages are determined by tenure rather than output to ensure equity.
- CRents protected by market power that enlarge top incomes without linking pay to results.
- DPay rewards on verifiable performance for highly productive workers.
Answer and solution
Answer: (D) Pay rewards on verifiable performance for highly productive workers.
The passage's second argument is about moral hazard and incentives. Effort cannot be observed directly, so paying people without regard to their performance fails to draw out their best effort. Some income inequality therefore helps growth by motivating workers, innovators and entrepreneurs.
Option D fits this exactly. Pay tied to verifiable performance gives highly productive workers more, which creates inequality, and that inequality comes from rewarding effort and results, which is what raises growth.
Option A is the strongest distractor, since concentrated ownership is also one of the passage's pro-growth arguments. But it is the third argument, about corporate governance and quick decisions, not the incentive argument the question asks about.
Option B ties wages to tenure rather than output, exactly the kind of pay that fails to elicit effort. Option C creates inequality through market power without linking pay to results, so it gives no incentive for effort.
Hence, option D (Pay rewards on verifiable performance for highly productive workers.).
Q11MCQReading Comprehension
Which one of the options below best summarises the passage?
- AThe passage argues that income inequality accelerates economic growth while also emphasising the significance of concerns regarding human capital accumulation, fertility rates, and political instability.
- BThe passage confines its discussion to financing gaps and corporate control while undercutting cross country evidence and overlooking the significance of concerns regarding human capital accumulation, fertility rates, and income redistribution under democratisation.
- CThe passage outlines investment, incentive, and governance channels through which income inequality may support economic growth and reports short-term gains while noting long term drawbacks.
- DThe passage claims that evaluating the effect of income inequality on economic growth without considering both short- and long-term consequences is misguided.
Answer and solution
Answer: (C) The passage outlines investment, incentive, and governance channels through which income inequality may support economic growth and reports short-term gains while noting long term drawbacks.
The passage first sets out three arguments for inequality helping growth: large sunk investments need concentrated wealth, unequal pay motivates effort, and concentrated ownership speeds corporate decisions. It cites studies finding short- and medium-term gains, one of which finds a negative link in the long run. It then reports that most studies find a negative relationship, and the channels behind it.
Option C captures the core of this: the investment, incentive and governance channels, the short-term gains, and the long-term drawbacks.
Option D is the strongest distractor, because the passage does contrast short-run and long-run effects. But the passage never claims that ignoring either horizon is 'misguided'; D turns a detail into a thesis the author does not argue.
Option A says the passage argues that inequality accelerates growth, but the passage presents both sides and reports that most studies find a negative link. Option B is wrong on every count: the passage goes beyond financing and corporate control, relies on cross-country evidence, and does discuss human capital, fertility and redistribution under democratisation.
Hence, option C (The passage outlines investment, incentive, and governance channels through which income inequality may support economic growth and reports short-term gains while noting long term drawbacks.).
Q12MCQReading Comprehension
The primary function of the three-part case for a positive income inequality–economic growth link in the first half of the passage is to show that:
- Ainequality can aid short-term growth in settings with high sunk costs, incentive alignment, and concentrated ownership.
- Bdispersed ownership speeds corporate decision-making and removes free rider problems.
- Cinequality boosts growth in every period and type of economy, regardless of finance or governance conditions.
- Dmature stock markets make wealth concentration unnecessary, yet they might still be harmful to investment.
Answer and solution
Answer: (A) inequality can aid short-term growth in settings with high sunk costs, incentive alignment, and concentrated ownership.
The first half gives three reasons why inequality may help growth, each tied to a setting. Where stock markets and financial institutions cannot mobilise money, concentrated wealth lets individuals meet large sunk costs. Where effort cannot be observed, unequal pay aligns incentives. Where ownership is dispersed, decisions are slow and free-riding appears, so concentrated ownership helps. The cited studies find the positive effect in the short (or medium) term, and one finds it turns negative in the long run.
Option A states exactly this: inequality can aid short-term growth in settings with high sunk costs, incentive alignment and concentrated ownership.
Option C is the strongest distractor, since it also says inequality boosts growth. But 'every period and type of economy, regardless of finance or governance conditions' overstates the case: the arguments depend on those conditions, and the evidence reverses in the long run.
Option B reverses the passage, which says dispersed ownership slows decisions and causes free-rider problems. Option D goes beyond the passage, which never says mature stock markets might harm investment.
Hence, option A (inequality can aid short-term growth in settings with high sunk costs, incentive alignment, and concentrated ownership.).
Q13MCQReading Comprehension
The passage refers to "democratization". Choose the one option below that comes closest to the opposite of this process.
- AThe coalition imposed term limits and strengthened judicial review in order to further entrench autocratic rule.
- BCorporate donations were capped and parties received public funding which was portrayed as establishing an oligarchy.
- CMunicipalities adopted participatory budgeting and recall elections which a press release called totalitarianism.
- DAfter the emergency decree, the regime shifted toward authoritarianism as suffrage narrowed and opposition parties were deregistered.
Answer and solution
Answer: (D) After the emergency decree, the regime shifted toward authoritarianism as suffrage narrowed and opposition parties were deregistered.
In the passage, democratization means extending suffrage to a wider class of people, which increases the political power of low- and middle-income voters. Its opposite would narrow the vote and shut people out of politics.
Option D describes exactly that: after an emergency decree the regime turns authoritarian, suffrage narrows and opposition parties are deregistered.
Option A is the strongest distractor, because it names autocratic rule. But the measures it lists, term limits and stronger judicial review, are checks on power typical of democracies; the claim that they 'entrench autocratic rule' is only a label, and nothing is taken away from voters.
Option B describes campaign-finance reform, capping corporate donations and funding parties publicly, which reduces no one's vote; only the 'oligarchy' label suggests otherwise. Option C describes participatory budgeting and recall elections, which widen participation, so they resemble democratization even though a press release calls them totalitarianism.
Hence, option D (After the emergency decree, the regime shifted toward authoritarianism as suffrage narrowed and opposition parties were deregistered.).
Q14MCQReading Comprehension
DIRECTIONS for the question:
The given sentence is missing in the paragraph below. Decide where it best fits among the options 1, 2, 3, or 4 indicated in the paragraph.
Sentence: Historically, silver has been, and still is, an important element in the business of 'show' visible in private houses, churches, government and diplomacy.
Paragraph: ____(1) ____. Timothy Schroder put it succinctly in suggesting that electric light and eating in the kitchen eroded this need. As he explained to the author, 'Silver, when illuminated by flickering candlelight, comes alive and almost dances before the eyes, but when lit by electric light it becomes flat and dead.' ____(2) ____. Domestic and economic changes may have worked against the market, but the London silver trade remained buoyant, thanks to the competition of collectors seeking grand display silver at the top end, and the buyers of 'collectables', like spoons and wine labels and 'novelties', at the bottom. ____(3) ____. Another factor that came into play was the systematic collection building of certain American museums over the period. Boston, Huntington Art Gallery and Williamsburg, among others, were largely supplied by London dealers. ____(4) ____.
- AOption 1
- BOption 2
- COption 3
- DOption 4
Answer and solution
Answer: (C) Option 3
The paragraph first explains why the old need for display silver faded: in Timothy Schroder's view, electric light and eating in the kitchen eroded it, because silver looks 'flat and dead' under electric light. It then says that, despite these changes, the London silver trade stayed buoyant thanks to collectors, and goes on: 'Another factor that came into play was' American museums building collections.
At blank 3, the sentence supplies a reason for the buoyant market: silver has been, and still is, important in the business of 'show' in houses, churches, government and diplomacy. 'Another factor' then adds the museums as a further reason.
Blank 1 (option A) looks tempting as an opener, but its claim that silver 'still is' central to show would be contradicted at once by Schroder's point that this need was eroded. Blank 2 (option B) has the same clash: it sits between Schroder's point and the admission that domestic and economic changes worked against the market. At blank 4 (option D), the sentence would trail after the museum example and end the paragraph on a claim nothing develops.
Hence, option C (Option 3).

Answer and solution
Answer: 3421
Sentence 3 opens the topic: women, unlike men, who are often applauded for aggression, are socialised to keep a lid on their anger.
Sentence 4 follows with 'Many of them', referring to these women, and gives the coach's experience: they are so at odds with their aggression that they pull their punches and must be urged to extend their arms.
Sentence 2 comes next. 'Once the taboos have been broken' points back to the suppression just described, and says women then find letting their fists fly intensely liberating.
Sentence 1 closes with 'But man, woman or otherwise', widening the point from women to everyone: how we handle anger shapes our life and character. That 'But' works only after the paragraph has focused on women, so this sentence comes last.
Sentence 4 cannot open the paragraph, because 'Many of them' needs the women of sentence 3, and it must come before 2, because the taboo has to be shown in action before we hear what happens once it is broken.
The answer is 3421.

Type in your answer (TITA). No negative mark for a wrong answer.
Answer and solution
Answer: 2143
The order is 2-1-4-3.
Sentence 2 makes the opening claim: the panoptic idea is a case of 'it's easy once you've thought of it' in the political sphere.
Sentence 1 says why it is so easy to apply: 'It can in fact be integrated into any function', such as education, medical treatment, production and punishment, and it can increase the effect of that function and tie power to production.
Sentence 4 opens with 'In short' and sums up sentence 1: power is not added on from outside like a heavy constraint but is built into the functions, raising their efficiency.
Sentence 3 ends the paragraph by turning that summary into a general statement: the panoptic mechanism is not just a hinge between power and a function, but a way of making power relations work through a function.
Starting with sentence 3 would put the general conclusion before the claim it rests on, and before the list in sentence 1 and its 'In short' summary in sentence 4, which are what lead up to it. Sentence 1's 'It can in fact' also needs a claim before it, which sentence 2 supplies.
The answer is 2143.

Passage for questions 17–20
DIRECTIONS for questions 17-20: The passage below is accompanied by four questions. Based on the passage, choose the best answer for each question.
Often the well intentioned music lover or the traditionally-minded professional composer asks two basic questions when faced with the electronic music phenomena: (1) . . . is this type of artistic creation music at all? and, (2) given that the product is accepted as music of a new type or order, is not such music 'inhuman'? . . . As Lejaren Hiller points out in his book Experimental Music (co-author Leonard M. Isaacson), two questions which often arise when music is discussed are: (a) the substance of musical communication and its symbolic and semantic significance, if any, and (b) the particular processes, both mental and technical, which are involved in creating and responding to musical composition. The ever-present popular concept of music as a direct, open, emotional expression and as a subjective form of communication from the composer, is, of course still that of the nineteenth century, when composers themselves spoke of music in those terms . . . But since the third decade of our century many composers have preferred more objective definitions of music, epitomized in Stravinsky's description of it as 'a form of speculation in terms of sound and time'. An acceptance of this more characteristic twentieth-century view of the art of musical composition will of course immediately bring the layman closer to an understanding of, and sympathetic response to, electronic music, even if the forms, sounds and approaches it uses will still be of a foreign nature to him.
A communication problem however will still remain. The principal barrier that electronic music presents at large, in relation to the communication process, is that composers in this medium are employing a new language of forms . . . where terms like 'densities', 'indefinite pitch relations', 'dynamic serialization', 'permutation', etc., are substitutes (or remote equivalents) for the traditional concepts of harmony, melody, rhythm, etc. . . . When the new structural procedures of electronic music are at last fully understood by the listener the barriers between him and the work he faces will be removed. . . .
The medium of electronic music has of course tempted many kinds of composers to try their hand at it . . . But the serious-minded composer approaches the world of electronic music with a more sophisticated and profound concept of creation. Although he knows that he can reproduce and employ melodic, rhythmic patterns and timbres of a traditional nature, he feels that it is in the exploration of sui generis languages and forms that the aesthetic magic of the new medium lies. And, conscientiously, he plunges into this search.
The second objection usually levelled against electronic music is much more innocent in nature. When people speak—sometimes very vehemently—of the 'inhuman' quality of this music they seem to forget that the composer is the one who fires the machines, collects the sounds, manipulates them, pushes the buttons, programs the computer, filters the sounds, establishes pitches and scales, splices tape, thinks of forms, and rounds up the over-all structure of the piece, as well as every detail of it.
Q17MCQReading Comprehension
What relation does the “communication problem” mentioned in paragraph 2 have to the questions that the author recounts at the beginning of the passage?
- AIts unfamiliar “language of forms” and novel terms mean that we cannot see electronic music as music since it does not employ traditional musical concepts.
- BUnfamiliar forms and terms might get in the way of our seeing electronic music as music, but this can be overcome.
- CThe communication problem is what allows us to see electronic music as music because music must be difficult to understand.
- DNone; they are unrelated to one another and form parts of different discussions.
Answer and solution
Answer: (B) Unfamiliar forms and terms might get in the way of our seeing electronic music as music, but this can be overcome.
The passage opens with two questions people ask about electronic music: is it music at all, and is it 'inhuman'? The first paragraph partly answers the first question: if we accept the twentieth-century view of music as 'speculation in terms of sound and time', we move closer to accepting electronic music.
Paragraph 2 then says 'A communication problem however will still remain': composers use a new language of forms, with terms like 'densities' and 'dynamic serialization' in place of harmony, melody and rhythm. This unfamiliarity is what may still stop listeners from hearing electronic music as music. But the author adds that once the new structural procedures are fully understood, the barriers 'will be removed'. So the problem bears on the first question and can be overcome.
Option A is the strongest distractor, because it also links the problem to the first question. But it says we cannot see electronic music as music, whereas the author says the barrier can be removed. Option C claims music must be hard to understand, which the passage never says. Option D denies a link that clearly exists.
Hence, option B (Unfamiliar forms and terms might get in the way of our seeing electronic music as music, but this can be overcome.).
Q18MCQReading Comprehension
From the context in which it is placed, the phrase “sui generis” in paragraph 3 suggests which one of the following?
- AIndescribable
- BParticular
- CUnaesthetic
- DGeneric
Answer and solution
Answer: (B) Particular
'Sui generis' is Latin for 'of its own kind'. In paragraph 3, the serious composer knows he could reuse traditional melodies, rhythms and timbres, but he feels the 'aesthetic magic' of the medium lies in exploring sui generis languages and forms: languages and forms particular to electronic music, not borrowed from older music. 'Particular' fits this sense.
Option A, 'Indescribable', is the strongest distractor, because these forms are new and unfamiliar. But the passage treats them as describable and learnable: paragraph 2 names terms such as 'densities' and 'permutation', and says listeners can come to understand the new procedures.
Option C, 'Unaesthetic', contradicts the passage, which places the aesthetic magic in these very forms. Option D, 'Generic', is close to the opposite of 'sui generis'.
Hence, option B (Particular).
Q19MCQReading Comprehension
The goal of the author over the course of this passage is to:
- Adifferentiate the modern composer from the nineteenth century composer.
- Bdefend electronic music from certain common charges.
- Cdifferentiate between electronic music and other forms of music.
- Ddefend the “serious-minded composer” from Lejaren Hill and Stravinsky.
Answer and solution
Answer: (B) defend electronic music from certain common charges.
The passage opens with two charges against electronic music: that it is not music at all, and that it is 'inhuman'. The rest of the passage answers them. Paragraph 1 argues that the twentieth-century view of music as 'speculation in terms of sound and time' lets us accept electronic music as music. Paragraph 2 admits a communication barrier but says it will be removed once the new structures are understood. Paragraph 3 shows the serious composer's careful search for new forms. Paragraph 4 calls the 'inhuman' charge innocent, since the composer controls every stage of the work. So the author's goal is to defend electronic music from these common charges.
Option A is the strongest distractor, because paragraph 1 does contrast the nineteenth-century view of music with the modern one. But that contrast is only a step in answering the first charge, not the aim of the whole passage.
Option C is likewise a step, not the goal. Option D is wrong because the author cites Hiller and Stravinsky in support; no composer is being defended from them.
Hence, option B (defend electronic music from certain common charges.).
Q20MCQReading Comprehension
The mention of Stravinsky’s description of music in the first paragraph does all the following EXCEPT:
- Acomplicate our notion of what is communicated through music.
- Ballow us to classify electronic music as music.
- Crespond to and expand upon earlier understandings of music.
- Dhelp us determine which sounds are musical and which are not.
Answer and solution
Answer: (D) help us determine which sounds are musical and which are not.
Stravinsky's description of music as 'a form of speculation in terms of sound and time' is set against the nineteenth-century idea of music as direct emotional expression from the composer.
It does what options A, B and C describe. It complicates what music communicates, since music becomes speculation rather than emotional expression (A). The author says accepting this view brings the listener closer to understanding electronic music, which lets us class it as music (B). And it is offered as the twentieth-century response to the earlier, nineteenth-century understanding (C).
Option B is the one most easily mistaken for the exception, since the passage says the view only brings the layman 'closer' to understanding. But making room for electronic music as music is exactly the role the view plays in the argument.
What the description does not do is give a test for sorting musical sounds from non-musical ones. It says what composition is, not which particular sounds qualify, and the passage never uses it that way.
Hence, option D (help us determine which sounds are musical and which are not.).
Reading passage
Passage for questions 21–24
DIRECTIONS for questions 21-24: The passage below is accompanied by four questions. Based on the passage, choose the best answer for each question.
Understanding the key properties of complex systems can help us clarify and deal with many new and existing global challenges, from pandemics to poverty . . . A recent study in Nature Physics found transitions to orderly states such as schooling in fish (all fish swimming in the same direction), can be caused, paradoxically, by randomness, or 'noise' feeding back on itself. That is, a misalignment among the fish causes further misalignment, eventually inducing a transition to schooling. Most of us wouldn't guess that noise can produce predictable behaviour. The result invites us to consider how technology such as contact-tracing apps, although informing us locally, might negatively impact our collective movement. If each of us changes our behaviour to avoid the infected, we might generate a collective pattern we had aimed to avoid: higher levels of interaction between the infected and susceptible, or high levels of interaction among the asymptomatic.
Complex systems also suffer from a special vulnerability to events that don't follow a normal distribution or 'bell curve'. When events are distributed normally, most outcomes are familiar and don't seem particularly striking. Height is a good example: it's pretty unusual for a man to be over 7 feet tall; most adults are between 5 and 6 feet, and there is no known person over 9 feet tall. But in collective settings where contagion shapes behaviour — a run on the banks, a scramble to buy toilet paper — the probability distributions for possible events are often heavy-tailed. There is a much higher probability of extreme events, such as a stock market crash or a massive surge in infections. These events are still unlikely, but they occur more frequently and are larger than would be expected under normal distributions.
What's more, once a rare but hugely significant 'tail' event takes place, this raises the probability of further tail events. We might call them second-order tail events; they include stock market gyrations after a big fall and earthquake aftershocks. The initial probability of second-order tail events is so tiny it's almost impossible to calculate — but once a first-order tail event occurs, the rules change, and the probability of a second-order tail event increases. The dynamics of tail events are complicated by the fact that they result from cascades of other unlikely events. When COVID-19 first struck, the stock market suffered stunning losses followed by an equally stunning recovery. Some of these dynamics are potentially attributable to former sports bettors, with no sports to bet on, entering the market as speculators rather than investors. The arrival of these new players might have increased inefficiencies and allowed savvy long-term investors to gain an edge over bettors with different goals. . . .
One reason a first-order tail event can induce further tail events is that it changes the perceived costs of our actions and changes the rules that we play by. This game-change is an example of another key complex systems concept: nonstationarity. A second, canonical example of nonstationarity is adaptation, as illustrated by the arms race involved in the coevolution of hosts and parasites [in which] each has to 'run' faster, just to keep up with the novel solutions the other one presents as they battle it out in evolutionary time.
Q21MCQReading Comprehension
All of the following inferences are supported by the passage EXCEPT that:
- Alearning can change the rules that actors face. So, a rare shock can alter payoffs and raise the odds of subsequent large disturbances within the same system, which supports the idea of second-order tail events.
- Bthe text attributes the COVID-19 pandemic rebound in financial markets solely to displaced sports bettors and treats their entry as the overriding cause of the rapid recovery across assets and time horizons.
- Cexamples like runs on banks and toilet paper scrambles illustrate how contagion can amplify local choices into system-wide cascades that surprise participants and lead to patterns they did not intend to create.
- Dheavy-tailed events make extreme outcomes more frequent and larger than bell curve expectations. This complicates forecasting and risk management in collective settings shaped by contagion and copying behaviour.
Answer and solution
Answer: (B) the text attributes the COVID-19 pandemic rebound in financial markets solely to displaced sports bettors and treats their entry as the overriding cause of the rapid recovery across assets and time horizons.
This is an EXCEPT question, so the answer is the one inference the passage does not support.
The passage says only that some of the market's dynamics are 'potentially attributable to' former sports bettors, whose arrival 'might have' increased inefficiencies. That is tentative and partial. Option B says the text makes the bettors the sole, overriding cause of the recovery across assets and time horizons, which it never does.
The other three are supported. Option A matches the last paragraph: a first-order tail event changes perceived costs and the rules, raising the odds of second-order tail events. It is the one most likely to look unsupported, since the passage never says 'learning', but a shock changing the rules is the passage's own idea. Option C matches the bank-run and toilet-paper examples and the warning about contact-tracing apps. Option D matches the second paragraph: heavy-tailed events are more frequent and larger than a bell curve predicts.
Hence, option B (the text attributes the COVID-19 pandemic rebound in financial markets solely to displaced sports bettors and treats their entry as the overriding cause of the rapid recovery across assets and time horizons.).
Q22MCQReading Comprehension
Which one of the following observations would most strengthen the passage’s claim that a first-order tail event raises the probability of further tail events in complex systems?
- AAfter a major equity crash, researchers find dense clusters of large daily moves for several weeks, with extreme days occurring far more often than in normal circumstances for assets with customarily low volatility profiles.
- BFollowing large earthquakes, regional seismic activity returns to baseline within hours with no aftershock sequence once data are adjusted for reporting effects, which suggests independence across events rather than any elevation in subsequent tail probabilities.
- CIn epidemic networks, initial super-spreading episodes are isolated spikes after which outbreak sizes match the baseline distribution from independent contact models across comparable cities with no rise in the frequency or size of later extreme clusters.
- DRiver discharge records show water levels fit a normal distribution with thin tails that match laboratory data, regardless of storms or floods.
Answer and solution
Answer: (A) After a major equity crash, researchers find dense clusters of large daily moves for several weeks, with extreme days occurring far more often than in normal circumstances for assets with customarily low volatility profiles.
The claim is that once a rare, extreme first-order event happens, further extreme events become more likely, as with stock-market gyrations after a big fall or aftershocks after an earthquake.
Option A gives exactly this kind of evidence: after a major crash, large daily moves cluster for weeks, and extreme days occur far more often than usual, even for assets that are normally calm. The first tail event is followed by a raised rate of further tail events.
Option D does not contradict anything, but it is about river levels that follow a thin-tailed normal distribution regardless of storms. It says nothing about one tail event following another, so it cannot strengthen the claim.
Options B and C would weaken the claim. In B, seismic activity returns to baseline within hours with no aftershocks; in C, super-spreading episodes are isolated spikes with no rise in later extreme clusters. Both suggest tail events are independent.
Hence, option A (After a major equity crash, researchers find dense clusters of large daily moves for several weeks, with extreme days occurring far more often than in normal circumstances for assets with customarily low volatility profiles.).
Q23MCQReading Comprehension
Which one of the options below best summarises the passage?
- AThe passage explains how speculative entrants always produce inefficiency after health shocks. Therefore, long-term investors invariably profit when new participants push prices away from fundamentals under pandemic conditions and comparable crises.
- BThe passage explains how social outcomes generally follow normal distributions. So, extreme events are negligible, and policy should stabilise averages rather than learn from large shocks in fast-changing collective settings.
- CThe passage explains how nonstationarity works in evolutionary biology and rejects applications in markets or public health because adaptation is exclusive to parasite-host systems and cannot arise in technology-mediated social dynamics.
- DThe passage explains how noise can create order, then shows why complex systems with contagion are vulnerable to heavy-tailed cascades. It also explains why early shocks change rules through nonstationarity with a market illustration during the COVID-19 disruption.
Answer and solution
Answer: (D) The passage explains how noise can create order, then shows why complex systems with contagion are vulnerable to heavy-tailed cascades. It also explains why early shocks change rules through nonstationarity with a market illustration during the COVID-19 disruption.
The passage builds three ideas about complex systems. Noise can create order: misalignment among fish feeds on itself until they school, and contact-tracing apps might produce a collective pattern people meant to avoid. Systems shaped by contagion face heavy-tailed events, such as bank runs and infection surges, which are more frequent and larger than a bell curve predicts. And a first-order tail event raises the odds of further ones by changing the rules, which is nonstationarity, illustrated by the COVID-19 stock market and by host-parasite coevolution.
Option D follows this sequence in order.
Option A is the strongest distractor because it uses the sports-bettor detail, but the passage offers that only tentatively and never says entrants 'always' create inefficiency or that investors 'invariably profit'.
Option B contradicts the passage, which stresses that extreme events are not negligible. Option C wrongly says the passage confines adaptation to hosts and parasites; it uses that case to illustrate a general concept.
Hence, option D (The passage explains how noise can create order, then shows why complex systems with contagion are vulnerable to heavy-tailed cascades. It also explains why early shocks change rules through nonstationarity with a market illustration during the COVID-19 disruption.).
Q24MCQReading Comprehension
The passage suggests that contact tracing apps could inadvertently raise risky interactions by altering local behaviour. Which one of the assumptions below is most necessary for that suggestion to hold?
- AIndividuals base movement choices partly on observed infections and on the behaviour of others. So, local responses interact, which turns many small adjustments into large scale patterns that can frustrate the intended aim of risk reduction.
- BMost users uninstall apps within a week, which leaves only highly exposed individuals participating. This neutralises any systematic bias in routing decisions and prevents any predictable change in aggregate contact patterns.
- CApp alerts always include precise location to within one metre and deliver real time updates for all users, which ensures that the data feed is perfectly accurate regardless of privacy settings, power limits, or network conditions.
- DUrban networks have uniform traffic conditions at all hours, which allows perfectly predictable routing independent of personal choices, social signals, or crowd reactions and, therefore, makes interdependence negligible in city movement decisions.
Answer and solution
Answer: (A) Individuals base movement choices partly on observed infections and on the behaviour of others. So, local responses interact, which turns many small adjustments into large scale patterns that can frustrate the intended aim of risk reduction.
The passage suggests that contact-tracing apps, though informative locally, might harm our collective movement: if each of us changes our behaviour to avoid the infected, together we may create what we meant to avoid, such as more contact between infected and susceptible people.
For this to happen, people must adjust their movements in response to infection information and to one another, so that many small local changes add up to a large pattern. Option A states exactly this. Without it, individual reactions could not combine into an unintended collective pattern.
Option D is the strongest distractor, because it too concerns interdependence, but it asserts the opposite: that movement is independent of choices and social signals. That would undermine the suggestion.
Option B says uninstalls prevent any change in aggregate contact patterns, which also works against the suggestion. Option C assumes perfectly accurate alerts, which is not needed; the concern holds even with imperfect data.
Hence, option A (Individuals base movement choices partly on observed infections and on the behaviour of others. So, local responses interact, which turns many small adjustments into large scale patterns that can frustrate the intended aim of risk reduction.).
