The one rule that governs everything here
Ornament loses marks. Precision wins them. Examiners reward clarity and economy and penalise decoration. Wordcraft never teaches a word so you can sound impressive. It teaches the word that is exactly right, the pair you must never swap, the verb a noun takes, and the fifteen words you can delete.
Glossary from the edition
18 words, each quoted in the sentence where it appeared in the 6 September 2026 edition. Meaning first, then the sentence, then where it came from.
Urging or exhorting; in law and diplomacy, describing an instrument that recommends a course of action without creating a legal obligation. From Latin hortari, to encourage. The precise antonym in this register is binding or mandatory, not optional.
हिंदी: प्रोत्साहक; आग्रह करने वाला (बाध्यकारी नहीं)
It is hortatory: General Assembly resolutions of this kind carry political and normative weight but impose no legal obligation on member states.
From UN General Assembly Endorses the Equal Earth Projection · The single most useful word an aspirant can own for international law questions. UNGA resolutions are hortatory; UNSC resolutions under Chapter VII are binding. Writing "the UN banned" when the instrument was hortatory is a factual error, not a stylistic one.
Of a map projection, preserving local angles and therefore the shapes of small features, at the cost of distorting area. From Latin conformare, to shape after. Its technical opposite is equal-area or equivalent; the two properties are mathematically incompatible.
हिंदी: समकोणीय; आकृति-संरक्षी (मानचित्र प्रक्षेप)
On a conformal map they remain circles but change size; on an equal-area map they keep their area but flatten into ellipses.
From UN General Assembly Endorses the Equal Earth Projection · Do not treat conformal as a loose synonym for "accurate". Every projection is accurate in something and wrong in something else; conformal names precisely which.
A line on the surface of the Earth crossing every meridian at the same angle, that is, a course of constant compass bearing; also called a rhumb line. From Greek loxos, slanting, and dromos, course. It is not the shortest route between two points, which is the great circle.
हिंदी: समवक्र रेखा; स्थिर दिक्मान वाली नौपथ रेखा
It is conformal, and it has one property no other projection of its era possessed: on a Mercator chart, a line of constant compass bearing, a rhumb line or loxodrome, is a straight line.
From UN General Assembly Endorses the Equal Earth Projection · The word explains why Mercator survived four centuries of criticism: it solved navigation, which was the problem it was built for.
The act of placing two things side by side, especially so that the contrast between them becomes the point. From Latin juxta, beside, plus ponere, to place. Stronger than comparison, which weighs; juxtaposition simply sets down and lets the reader see.
हिंदी: सन्निकटता; आमने-सामने रखना
The juxtaposition is the argument in miniature: the agency delivering a first-of-its-kind national capability on the same day its staff ask what will be left for it to build.
From ISRO Employee Associations Question the Direction of Space Privatisation · An essay word that earns its keep. It lets you make a point by arrangement rather than by assertion, which is usually more persuasive.
The breaking of a total back into the parts it was made from, so that the distribution inside an average becomes visible. The exact opposite of aggregation, and from the same root grex, gregis, a flock. In statistics the usual axes are income decile, sex, caste, region and sector.
हिंदी: विसंकलन; समुच्चय को अलग-अलग करके देखना
The corrective habit is to demand the disaggregation before accepting the conclusion.
From Growth Without Shared Prosperity: The Case for Intersectional Validation · The one-word answer to any headline average. A 7.8 per cent growth figure is compatible with many distributions, and the examiner is asking which one. Pair it with aggregate above: they are the same root pulling in opposite directions.
Matter that settles out of water, especially the silt and sand a river carries and deposits. From Latin sedere, to sit. In river geomorphology, the sediment load is what builds floodplains, deltas and islands, so trapping it behind a dam has effects far beyond water volume.
हिंदी: तलछट; गाद
Trapping sediment behind a dam changes downstream geomorphology, aquatic ecology and soil fertility, quite apart from water volume.
From China's Yarlung Zangbo Mega Dam and India's Downstream Concerns · The word that turns a water-sharing answer into a geography answer. Majuli, the Sundarbans and the Kosi fan are all sediment stories.
In labour economics, the condition of employment that lies outside written contracts, social security and regulatory protection. Distinct from the everyday sense of casual manner. The measured opposite is formal or organised sector employment, not politeness.
हिंदी: अनौपचारिकता; असंगठित रोज़गार
The central charge is the normalisation of informality for workers lacking agency, conditions, wages and regulatory support.
From Growth Without Shared Prosperity: The Case for Intersectional Validation · Use the technical sense in GS3 and mark it: "informality, in the labour-market sense". Otherwise an examiner reads the social meaning.
A total formed by combining separate items; as a verb, to combine them. From Latin ad, to, plus grex, gregis, a flock: literally to drive to the flock. Note the stress shift between noun and verb, which is the usual English pattern.
हिंदी: समुच्चय; कुल जोड़
A mean can be produced by many distributions, most of which would not satisfy the goal the aggregate is invoked to support.
From Growth Without Shared Prosperity: The Case for Intersectional Validation · Today the same word carries three arguments: the GDP deflator, the totaliser and the growth critique. Aggregation buys a headline and costs you the ability to see inside it.
What remains after something has been subtracted or accounted for. From Latin residuum, remainder. In national accounting, gross value added is a residual: output minus intermediate consumption, which is why small errors in two large numbers move it disproportionately.
हिंदी: अवशिष्ट; शेष भाग
It is a derived residual under double deflation and can be negative while both input and output prices are rising.
From Reading the Evidence Beyond the Numbers: The Official Defence of the GDP Deflator · Whenever a quantity is a residual, expect it to be volatile. That single observation answers most questions about why manufacturing GVA behaves oddly.
A price index used to convert a nominal magnitude into a real one by removing the effect of price change. An implicit deflator is not observed directly but derived, by dividing the nominal magnitude by the real one, which is why it can behave counter-intuitively.
हिंदी: अपस्फीतिकारक; मूल्य सूचकांक जो नाममात्र को वास्तविक में बदले
The implicit GVA deflator then turns negative even though both output and input prices are rising.
From Reading the Evidence Beyond the Numbers: The Official Defence of the GDP Deflator · A negative implicit deflator does not mean falling prices. It is an artefact of subtraction under double deflation, and saying so correctly is worth a mark.
The formation of a settled disposition through repeated practice. From Latin habitus, condition or bearing. In Aristotelian ethics it is the mechanism by which virtue is acquired: not by learning a rule but by doing the thing until doing it becomes character.
हिंदी: अभ्यासजन्य आदत; आदत द्वारा चरित्र-निर्माण
Aristotle held that virtue is acquired by habituation until it becomes disposition, which requires a person to imitate rather than a text to read.
From The Socratic Teacher in an Age of Algorithms · The GS4 word that separates virtue ethics from deontology in one term. Deontology asks what rule applies; habituation asks what person you are becoming.
The act of passing something on, whether knowledge, disease, power or a signal. From Latin trans, across, plus mittere, to send. In education debates it names the lecture function specifically, as against diagnosis, judgement and relationship.
हिंदी: संप्रेषण; ज्ञान का हस्तांतरण
Nilay is right that a role defined by transmission is finished, and his critics are right that the alternative requires resourcing.
From The Socratic Teacher in an Age of Algorithms · A precise word for AI-and-work answers across sectors: ask which functions of a role are transmission, because those are the substitutable ones.
Occurring at the same time as the thing it relates to. From Latin con, together, plus tempus, time. In evidence and audit it is a term of art: a contemporaneous record is made at the moment of the event, which is why it is trusted more than a later reconstruction.
हिंदी: समकालिक; उसी समय होने वाला
Aggregation destroys the only contemporaneous, self-correcting audit available at the counting table.
From The Totaliser Question: Voter Anonymity Against Verifiable Counting · Distinguish from contemporary, which means belonging to the present age. A contemporaneous note is made at the time; a contemporary writer is alive now.
A third currency used to bridge two others that are not directly exchanged, because few banks hold both. The classic case is the US dollar standing between two developing-country currencies in a trade involving no American party.
हिंदी: माध्यम मुद्रा; विनिमय में सेतु का काम करने वाली मुद्रा
The dollar is the vehicle currency, and no American party is involved.
From Why BRICS Is Exploring Cross-Border Payments, and What India Actually Wants · The term that makes de-dollarisation debates precise. The dollar is used here as plumbing, not as a reserve asset, and the two roles have different remedies.
General agreement; in multilateral procedure, a decision rule under which a text is adopted only if no participant objects. From Latin consentire, to feel together. It is not the same as unanimity by vote: consensus means the absence of stated objection.
हिंदी: सर्वसम्मति; आम सहमति
It was reached by consensus, the CCW’s operating rule, which means every participating High Contracting Party had to accept it.
From 128 States Agree the First Consensus Text on Lethal Autonomous Weapons · Consensus procedure explains pace. Where one party can block, outcomes are slow and weak, which is the standing critique of the CCW and of the WTO.
A method or theory of interpretation, especially of texts. From Greek hermeneuein, to interpret. Used of the principles by which a reader decides what a text means, as against what its words literally say.
हिंदी: व्याख्याशास्त्र; पाठ की व्याख्या-पद्धति
The cost is the charge of selectivity: a hermeneutic supple enough to find an egalitarian reading can also be used to find its opposite, and it can shade into pretending a text says what one wishes it said.
From How Should a Constitutional Republic Read Its Ancient Texts? · Precise and slightly technical. Use it in GS1 society and essay answers about tradition and reform; avoid it where interpretation would do.
The act of spreading exposure across several sources, markets or assets so that no single failure is decisive. From Latin diversus, turned different ways. Note the distinction the edition draws: replacing one concentration with another is substitution, not diversification.
हिंदी: विविधीकरण; स्रोतों का विस्तार
The principle is that replacing a single-region dependence with a single-country dependence is not diversification; it is substitution.
From US LPG Is Not a Silver Bullet for India, Says World Liquid Gas Association · That one distinction converts a vague energy-security paragraph into an argument. Ask always: is this diversification, or a change of supplier?
Investing a fixed sum at regular intervals so that more units are bought when prices are low and fewer when they are high, lowering the average acquisition cost. The Indian name for what is elsewhere called dollar cost averaging.
हिंदी: रुपया लागत औसतन; नियमित निवेश से औसत लागत घटाना
Its purpose is rupee cost averaging: buying more units when prices fall and fewer when they rise, which lowers the average acquisition cost over time and removes the need to time the market.
From Crypto SIPs and the Maturing of India's Retail Digital Asset Market · It averages the entry price. It does not reduce the volatility of the asset, and it does not supply a regulator. Say so in an answer.
The seven lessons
One entry of each type, every day: a system, not a word list.
1 · Root & family
grex, gregis
Latin · "a flock, a herd" · the verb gregare, to gather into a flock
Today’s edition argues about arithmetic three times, and the same Latin flock is standing behind each argument. The statisticians at MoSPI explain that real value added is what is left when one large number is taken from another. The Election Commission objects that adding fourteen voting machines together hides a fault inside the sum. And a critique of the growth figures asks who is inside the 7.8 per cent. Every one of these is a quarrel about aggregation: about what you can see once things have been driven together into one flock.
| Word | Literal herd | What it does now |
|---|---|---|
| aggregate | ad- "to" | driven to the flock: a total formed from separate items |
| segregate | se- "apart" | driven apart from the flock: separated, often by force of law |
| congregate | con- "together" | coming to the flock: gathering of one’s own accord |
| gregarious | bare stem | liking the flock: sociable, fond of company |
| egregious | e- "out of" | standing out from the flock: once distinguished, now flagrantly bad |
| desegregate | de- + se- | undoing the separation: the civil-rights verb |
The word that changed sides. Egregious once meant remarkably good, one sheep visibly finer than the flock. English kept the standing-out and reversed the verdict, so it now means remarkably bad. When a word can carry praise or condemnation depending on the century, check the century.
And a trap worth naming. The harvest script that prepared this pack filed aggregate under regere, "to rule", alongside regulate and regional. That is a reasonable guess from the letters and it is wrong: aggregate is a flock word, regulate is a ruling word. Similar spellings, different parents. Checking that is exactly the habit the edition recommends for figures.
Every word here is at work in the 6 September edition: aggregate and aggregation in the GDP deflator editorial and in the totaliser editorial, and disaggregate in the growth critique.
2 · Confusable pair
device / devise
Two pairs the ear can settle, two it cannot
device / devise. Device is the noun, rhyming with ice; devise is the verb, rhyming with prize. The map article uses both within a few paragraphs: Tissot’s indicatrix is "the standard device", and Mercator "devised" his projection in 1569. Say the sentence aloud and the wrong one announces itself.
precede / proceed. To precede is to come before; to proceed is to go forward. The Himalaya editorial asks that political architecture "follow demonstrated technical trust rather than precede it". The linguistic-states editorial says later demands "proceed on the logic" of 1956. Note the spellings: one e in precede, double e in proceed, and the noun procedure drops one again.
systematic / systemic. This is the pair that costs marks. Systematic means methodical, done according to a system: today’s crypto article is about Systematic Investment Plans, money put in on a fixed schedule, and the map article accuses Mercator of a "systematic bias", a bias that recurs by method rather than by accident. Systemic means belonging to the whole system, affecting all of it: systemic risk, systemic discrimination, a systemic failure. The BRICS payments editorial argues that routing more traffic through fewer channels raises fragility, and that fragility is systemic, not systematic. A systematic error is repeatable; a systemic one is everywhere.
continual / continuous. Continuous means unbroken; continual means repeated with gaps. The teachers article refers to NEP 2020’s provisions on continuous professional development, and unbroken is what is meant: development that does not stop at induction. Continual professional development would mean it keeps being interrupted and restarted, which is the complaint rather than the policy. The Yarlung Zangbo article gives the physical case: a run-of-the-river scheme passes water through continuously, while a reservoir makes releases continual.
device and devised in the map article, which also supplies systematic bias; precede in the Himalaya editorial and proceed in the linguistic states editorial; Systematic Investment Plans in the crypto SIP article; continuous professional development in the teachers article. The edition never uses systemic or continual, and being able to say where each would have belonged is the test.
3 · Collocation
what a river does, and what is done to it
Hydrological collocations from the Yarlung Zangbo article
Water writing has its own verbs, and an answer that reaches for generic ones ("the dam will stop the water") loses the distinction the examiner is testing. Today’s Yarlung Zangbo article supplies the whole set, because the entire Indian concern rests on which verb is true.
| Subject | Its verb | What it commits you to |
|---|---|---|
| a river | rises in, flows through, becomes | the Yarlung Zangbo becomes the Siang and then the Brahmaputra |
| a dam | is commissioned, after being built | China has already commissioned the Zangmu dam; commissioned means operating, not merely finished |
| a reservoir | impounds; water is impounded | the technical question is how much water will be impounded |
| water | is diverted into a tunnel or canal | water is to be diverted at the Great Bend into a tunnel of about 40 km |
| a reservoir | releases; a release is made | lean-season releases are the downstream concern, not annual volume |
| sediment | is trapped, then deposited | trapping sediment changes downstream geomorphology |
| a catchment | contributes or adds flow | the Indian catchment contributes the bulk of the Brahmaputra’s volume |
The label that does not mean what it says. "Run-of-the-river" sounds like a promise that nothing is held back, and the article’s central correction is that it is not one: this project is described as run-of-the-river and still involves a reservoir and a 40 km diversion tunnel. A true run-of-the-river scheme passes water through as it arrives. A scheme with a reservoir can hold back and release. Those are different verbs because they are different powers.
Impound is the precise word, and it is not "block". To impound is to collect and hold water behind a structure. It says nothing about permanence, which is why it is the honest verb: an upstream dam cannot switch a river off, but it can decide when the water arrives. Write "impounded" and you have claimed exactly that and nothing more.
Every verb here is the article’s own: commissioned, impounded, diverted, released, trapped and run-of-the-river all appear in the Yarlung Zangbo article, which also supplies catchment, upstream and downstream. The glacier editorial at the Himalayan tripartite mechanism adds the hazard vocabulary that sits on top of it.
4 · From the edition
hortatory
HOR-tuh-tuh-ree · from Latin hortari, to encourage, to urge
On 4 September the United Nations General Assembly voted 164 to 1 to encourage the world to stop drawing Africa small. It did not ban the Mercator projection. It did not require anyone to adopt Equal Earth. The map article names what it did in one word: the resolution is hortatory, carrying political and normative weight while imposing no legal obligation.
Why this is the word of the day. Almost every wrong sentence written about this story will be wrong in the same way: "the UN banned the Mercator map". One adjective prevents it. A hortatory instrument urges; a binding instrument obliges. The distinction runs through the whole of international law, and today’s edition happens to supply both sides of it: the General Assembly resolution urges, while the lethal autonomous weapons text agreed in Geneva is described as non-binding for the same reason.
| Register | Word | Force |
|---|---|---|
| urging | hortatory, recommendatory, aspirational, exhortatory | no legal obligation created |
| obliging | binding, mandatory, obligatory, peremptory | legal obligation created |
| Indian constitutional analogue | Directive Principles under Part IV | "not enforceable by any court", Article 37 |
The Indian analogue is worth carrying. Article 37 says the Directive Principles are "not enforceable by any court" and yet "fundamental in the governance of the country". That is a hortatory provision described exactly. If you can explain why a Directive Principle matters despite not being enforceable, you can explain why a General Assembly resolution matters despite not binding, and the same paragraph serves both papers.
The word is used exactly once in the edition, in the Equal Earth article, and its sense is confirmed by the parallel description of the Geneva text as non-binding in the lethal autonomous weapons article.
5 · Say it shorter
the zombie noun
nominalisation · a verb turned into a noun, and the sentence built around the corpse
English lets you turn almost any verb into a noun: aggregate becomes aggregation, conceal becomes concealment, verify becomes verification. The nouns are not wrong. What is wrong is what happens next. A sentence with a nominalisation at its centre needs a weak verb to hold it up, usually is, are, results in, takes place, and the sentence gets longer while saying less.
The test is mechanical. Find the nouns ending in -tion, -ment, -ance, -ity, -ness. Ask what verb is trapped inside each. Then ask who is doing it. Put the doer in front of the freed verb and the sentence usually loses a third of its length.
| Zombie | Verb inside | What it needs |
|---|---|---|
| the aggregation of the counts | aggregate | a doer: who aggregates? |
| the concealment of discrepancies | conceal | a doer: what conceals? |
| the implementation of the policy | implement | a doer: which department? |
| an assessment was undertaken | assess | a doer, and a plain past tense |
The exception that keeps you honest. Nominalisations are useful when the process itself is the subject of study, which is why today’s statistical editorial cannot avoid deflation, aggregation and extrapolation. Those name techniques. The rule is not "never nominalise"; it is "never nominalise where a person or an institution is doing something".
The heaviest sentences in today’s edition, by count of nominalisations, come from the roundup, the totaliser editorial and the AI teaching editorial. The models below are deflations of the edition’s own prose.
6 · Usage watch
per cent · percentage point
the error that turns a correct figure into a wrong claim
Today’s edition is unusually full of shares, and shares are where careful aspirants lose marks. The LPG article records that the Gulf suppliers' share of India’s imports went from 81 per cent in February 2026 to 16 per cent in May, while the American share went from 14 per cent to about 67 per cent. Now describe that movement. Almost everyone writes "the Gulf share fell by 65 per cent". It did not.
The rule. When a quantity that is itself measured in per cent changes, the arithmetic difference is measured in percentage points, never in per cent. The per cent figure is the relative change, which is a different and usually much larger number.
| Movement in today’s edition | In percentage points | In per cent |
|---|---|---|
| Gulf share, 81 to 16 | a fall of 65 percentage points | a fall of about 80 per cent |
| US share, 14 to about 67 | a rise of 53 percentage points | a rise of nearly 380 per cent, close to fivefold |
| crypto SIP adopters, 2 to 4 up to about 20 | a rise of some 16 to 18 percentage points | a five to tenfold rise |
Per cent, percent or percentage. British and Indian prose writes per cent as two words; American writes percent. Percentage is the noun you use when no figure is attached: "a large percentage of imports", never "a large per cent of imports". And percentile is a rank, not a share: the 90th percentile is a position in a distribution, not ninety per cent of anything.
Crore, lakh and who is reading. Today’s edition writes ₹51,000 crore of crypto investment, a data centre campus at up to ₹70,000 crore, and 4.5 lakh teachers in Karnataka. These are correct and idiomatic in Indian English, and you should use them. Know the conversion for the moment an examiner or an international source states the same quantity differently: 1 lakh is 100,000, 1 crore is 10 million, so ₹51,000 crore is ₹510 billion and 4.5 lakh is 450,000. One caution: the edition writes both Rs and ₹. Either is acceptable; mixing them in one answer is not.
The share figures are from the LPG article, whose table tracks the Gulf and US shares across February, May and August 2026; the adoption figures are from the crypto SIP article; ₹70,000 crore is the Hyderabad campus figure in the data centre article and 4.5 lakh teachers is from the teachers article.
7 · Idiom in formal register
a silver bullet · to hold water
two idioms the edition uses, and one it uses literally
a silver bullet. A single, simple solution that resolves a complex problem at a stroke. From European folklore, in which a werewolf could be killed only by a bullet cast from silver. It is almost always used in the negative, and today’s headline is the standard shape: US LPG "is not a silver bullet for India". The idiom carries a built-in scepticism, so you rarely announce that you have found one; you say that something is not one.
to hold water. Of an argument, to survive scrutiny; to be sound. The image is a vessel that does not leak. "The claim does not hold water" means the reasoning fails, not that the claim is unpopular.
And the trap today’s edition sets by accident. The Yarlung Zangbo article writes that a scheme with a reservoir "can hold water back and release it on a schedule that suits generation". That is the literal sense, water in a dam, not the idiom. Same three words, entirely different use. When an idiom’s literal meaning is also available in your subject, the reader will take the literal one, so make the context decide.
| Idiom | Means | Safe register |
|---|---|---|
| a silver bullet | one simple fix for a complex problem | essay, editorial; usually negative |
| hold water | of an argument, to be sound | essay, editorial; avoid in water-policy answers |
| a shock absorber | something that cushions a sudden blow | GS3 economy; today, storage against a supply shock |
| the sorrow of Bihar | the Kosi river | GS1 geography; a fixed epithet, not a live metaphor |
The rule for examination prose. One idiom per answer, never in the opening sentence, and never where its literal sense competes with your subject matter. An idiom earns its place by compressing an argument; two in a paragraph make the prose sound borrowed.
Silver bullet is the frame of the LPG article, taken from the WLGA chief’s own words. Hold water appears in its literal sense in the Yarlung Zangbo article, and shock absorber is used figuratively for storage in the LPG piece.

Root & family · grex, gregis
-
Fill the blank Circle the letter that completes the sentence.
The Election Commission objects that ___ across fourteen machines conceals a fault inside the total.
- aggregation
- segregation
- congregation
- regulation
Answer
aggregation. Aggregation is the driving-together of separate counts into one. That is precisely the property the Commission says destroys booth-level verification.
-
Choose one Circle the letter of the correct option.
Which word does NOT descend from grex, gregis?
- regulate
- segregate
- gregarious
- egregious
Answer
regulate. Regulate comes from regere, to rule, alongside regional and regime. The other three are flock words. The resemblance is coincidence.
-
Choose one Circle the letter of the correct option.
In older English, "egregious" meant:
- Remarkably good, standing out from the flock
- Densely crowded
- Legally separated
- Sociable and talkative
Answer
Remarkably good, standing out from the flock. E- "out of" plus grex: one sheep visibly finer than the herd. English kept the standing-out and reversed the verdict.
-
Match the pairs Write the letter from the right against each number on the left.
Match the prefix to the direction of travel.
- ad-
- se-
- con-
- e-
- out of the flock: egregious
- together to the flock: congregate
- apart from the flock: segregate
- to the flock: aggregate
Answer
- ad-: to the flock: aggregate
- se-: apart from the flock: segregate
- con-: together to the flock: congregate
- e-: out of the flock: egregious
Each prefix names a direction relative to the herd. Fix the picture and the six words fix themselves.
-
Find the error Circle it in the sentence below, then write the correction.
Find the word that is not from this root family.
aggregate segregate congregate regional gregarious
Answer
regional → regional is from regere, to rule. Regional shares four letters and no ancestry. The harvest script made exactly this mistake, which is why the lesson names it.
-
Say it shorter Rewrite the sentence below within the word limit.
Deflate; sixteen words or fewer.
The aggregation of the counts across the cluster of machines results in the concealment of any discrepancy that may exist in an individual unit.
Word limit 16
Model
Aggregating the cluster hides a discrepancy in any single machine. Twenty-three words to ten. Three zombie nouns, aggregation, concealment and discrepancy, hold a sentence up; free the verbs and it stands on its own.
Confusable pair · device / devise · precede / proceed · systematic / systemic · continual / continuous
-
Fill the blank Circle the letter that completes the sentence.
Gerardus Mercator ___ his projection in 1569.
- devised
- deviced
- device
- devising
Answer
devised. The verb is devise, so the past tense is devised. Deviced is not a word.
-
Fill the blank Circle the letter that completes the sentence.
Routing more cross-border traffic through fewer channels raises ___ risk.
- systemic
- systematic
- systemically
- systematically
Answer
systemic. The risk is to the whole system, which is systemic. A systematic risk would be one generated by a method, which is not the BRICS argument.
-
Fill the blank Circle the letter that completes the sentence.
NEP 2020 provides for ___ professional development, meaning it does not stop after induction.
- continuous
- continual
- continuing
- continuance
Answer
continuous. Unbroken is meant, so continuous. Continual would describe development repeatedly interrupted, which is the problem rather than the policy.
-
Choose one Circle the letter of the correct option.
Which sentence uses precede correctly?
- Technical trust should precede the political architecture
- Let us precede with the next agenda item
- The committee will precede to vote
- Please precede in an orderly line
Answer
Technical trust should precede the political architecture. Precede means to come before. The other three want proceed, to go forward.

Answer
- systematic: done by a method, repeatable
- systemic: belonging to the whole system
- continuous: unbroken
- continual: repeated, with gaps
Two pairs, four distinct claims. Swapping any one of them changes what the sentence asserts about the world.
-
Find the error Circle it in the sentence below, then write the correction.
Find the wrong word.
The crash exposed a systematic weakness across the entire banking sector.
Answer
systematic → systemic. A weakness across the entire sector belongs to the whole system, so systemic. Systematic would say the weakness was produced methodically, which is a different and much stronger claim.
Collocation · the verbs of the river and the dam: commissioned, impounded, diverted, trapped, released
-
Fill the blank Circle the letter that completes the sentence.
The operative question is how much water will be ___ behind the structure.
- impounded
- imported
- impeded
- imposed
Answer
impounded. To impound is to collect and hold water behind a dam. It is the exact verb, and it claims control over timing rather than the power to stop the river.
-
Fill the blank Circle the letter that completes the sentence.
China has already ___ the Zangmu dam on the middle reaches of the Yarlung Zangbo.
- commissioned
- enacted
- ratified
- notified
Answer
commissioned. A dam is commissioned when it begins operating. The other three verbs belong to legal instruments, not infrastructure.
-
Choose one Circle the letter of the correct option.
What does calling a project "run-of-the-river" NOT establish?
- That it has no reservoir
- That it uses the river’s own descent
- That it generates power from flow
- That it is a hydropower scheme
Answer
That it has no reservoir. The article’s central correction: this project is described as run-of-the-river and still involves a reservoir and a 40 km diversion tunnel. The label describes intent, not the absence of storage.
-
Match the pairs Write the letter from the right against each number on the left.
Match each subject to the verb that belongs to it.

Answer
- a dam: is commissioned
- a reservoir: impounds
- water: is diverted
- sediment: is trapped
- a catchment: contributes flow

An upstream dam can block the Brahmaputra during the lean season.
Answer
block → affect the timing of. The Tibetan reach contributes a minority of the Brahmaputra’s annual flow, so an upstream dam cannot block it. It can alter flow timing and lean-season releases, which is the accurate and examinable claim.

What did the Correct the Map resolution actually do?
- Encouraged the use of equal-area projections where relative size matters
- Banned the Mercator projection in member states
- Required schools to adopt Equal Earth within two years
- Made Equal Earth the sole official UN projection
Answer
Encouraged the use of equal-area projections where relative size matters. It encourages and asks that the limits of every flat map be taught. It neither bans nor mandates, which is what hortatory means in practice.

- It rose by 53 per cent
- It rose by 53 percentage points
- It rose nearly fivefold
- It rose by nearly 380 per cent
Answer
It rose by 53 per cent. The 53 is a gap between two percentages, so it is 53 percentage points. Expressed in per cent the rise is nearly 380 per cent, because 53 is measured against the original 14.

Reading in the CSAT shape
A passage quoted from UN General Assembly Endorses the Equal Earth Projection, then inference questions on it.
Every flat map of a spherical Earth distorts something, and it does so as a matter of mathematics rather than of skill or intent. A sphere has Gaussian curvature; a plane does not. No transformation between them can preserve all metric properties at once. A projection may preserve area, or shape and local angles, or distance from a point, or direction from a point, but never all of them together. The cartographer's choice is therefore never neutral. It is a decision about what to sacrifice, and that decision encodes a purpose.
That final clause is the intellectually honest core of the resolution, and the one most likely to be missed. The claim is not that Equal Earth is the true map. There is no true flat map. The claim is that a projection should be chosen to fit its purpose, and that a projection built for maritime navigation was never fit for teaching children the relative size of continents.
According to the passage, why is distortion unavoidable on a flat map?
- A sphere has Gaussian curvature and a plane does not, so no transformation preserves all metric properties
- Cartographers lack the skill to draw the Earth accurately
- Printing technology cannot reproduce curved surfaces
- The Earth is not a perfect sphere
Answer
A sphere has Gaussian curvature and a plane does not, so no transformation preserves all metric properties. The passage locates the cause in mathematics, not in skill or intent, and names Gaussian curvature as the reason no transformation can preserve everything at once.
The passage states that the cartographer’s choice "is never neutral". Which inference is best supported?
- Choosing a projection means choosing which property to sacrifice, and that choice serves some purpose
- Cartographers deliberately misrepresent the world for political ends
- All projections are equally misleading and none should be preferred
- Neutral projections exist but are rarely used
Answer
Choosing a projection means choosing which property to sacrifice, and that choice serves some purpose. The passage says the choice "is a decision about what to sacrifice, and that decision encodes a purpose". It attributes purpose, not deliberate deception, and it does not say all projections are equivalent.
Which statement would the author most likely accept?
- A conformal projection remains the right choice for marine navigation
- Equal Earth should replace every other projection in all uses
- The Mercator projection was a mistake from the moment it was devised
- Only equal-area projections can be described as honest
Answer
A conformal projection remains the right choice for marine navigation. The argument is fitness for purpose. The passage says a projection built for maritime navigation was unfit for teaching relative size, which implies it remains fit for navigation.
The phrase "There is no true flat map" functions in the argument to:
- Prevent the reader from treating Equal Earth as simply correct
- Concede that the resolution has no practical value
- Establish that all maps are equally unreliable
- Argue that only globes should be used in classrooms
Answer
Prevent the reader from treating Equal Earth as simply correct. It guards against replacing one uncritically accepted projection with another, which is why the passage calls this the honest core of the resolution.
