CAT 2020 VARC Questions — Slot 1

A question about applying the passage's rules for each currency to a concrete transaction — so first pin down what the passage says about each payment method for a small purchase worth one-eighth of a bolt.

The key line on textiles is explicit: "If consumers cut textiles into smaller pieces to buy or sell something worth less than a full bolt, that, too, greatly lessened the value of the textiles." Cutting one-eighth off a brand-new bolt destroys the value of what remains — you lose far more than the one-eighth you spent. That is a money-losing move, so it is not economically sound.

Why the other options are sound:

• A (grain): Grain was a recognised Tang currency; paying its weight-equivalent is a workable transaction.
• B (a faded bolt of roughly equal value): By the option's own wording, the faded bolt carries "approximately the same value" as the purchase, so it is a fair payment despite being worn.
• C (coins): The passage says coins were "a convenient medium of exchange, especially for smaller transactions" and were "better suited for smaller transactions" — so this is the most natural payment of all.

💡 Teacher tip: When a question sets up a specific scenario, translate each option into the passage's own terms before judging it. Here, the trigger phrase is "cut textiles into smaller pieces" — the passage flags exactly that act as value-destroying.

Answer: D

An EXCEPT question asking what the words "steady" and "stable" do not indicate — so trace each occurrence back to the exact property the author is describing.

The two words appear in specific contexts:

• "The dimensions of a bolt of silk held remarkably steady from the third to the tenth century: 56 cm wide and 12 m long." — "steady" points to reliable measurements (option C).
• "The values of different textiles were also more stable than the fluctuating values of coins." — "stable" points to reliable quality/value (option B).
• The reason values stayed stable was that "textile production was widespread and there were fewer problems with the supply of textiles" — so "stable" is also underpinned by reliable supply (option D).

Transportation, by contrast, is discussed separately: textiles "weighed less than their equivalent in coins," which is a point about ease and cost of moving goods. It is never tied to the words "steady" or "stable," and it is not a claim about transportation being reliable.

💡 Teacher tip: For an EXCEPT question built on two keywords, locate every place those keywords appear and ask, "What property is the author actually describing here?" Anything discussed nearby but not connected to those words is your answer.

Answer: A

An inference question — check each option against what the passage actually states or logically supports, and eliminate the ones that distort the text.

Why D is correct: The author closes by drawing an explicit parallel: "our own currency system today has some similarities even as it is changing in front of our eyes." The Tang used coins for small transactions, textiles for large ones, and grain for tax obligations; today we use coins for small payments, banknotes and cards/cheques for larger ones. The structural similarity is directly supported.

Why the others fail:

• A (deteriorating currency not used officially): This reverses the passage. Grain "rotted easily" — it deteriorated — yet taxpayers were "required to pay grain to the government" and "official salaries were expressed in weights of grain." So a perishable currency was used for official work.
• B (coins more valuable and durable than textiles): Mixed up. Durability was indeed coins' advantage, but the passage says textile "values…were more stable than the fluctuating values of coins," so coins were not more valuable. The option stitches one true detail onto a false comparison.
• C (grain the most used currency): Directly contradicted: "Grain, because it rotted easily, was not used nearly as much as coins and textiles." Government requirement made grain a tax medium, not the most used currency.

💡 Teacher tip: Inference options often take a true detail and stretch it into a false generalisation. Test each half of the statement separately — if either half breaks, the option fails.

Answer: D

An EXCEPT question about features the modern system shares with the Tang system — so for each option, confirm the feature exists in both eras; the one that belongs to only one is the answer.

The Tang system is presented as stable across centuries; transformation is a feature of today only. The passage never suggests the Tang system was itself transforming — quite the opposite, its silk-bolt dimensions stayed fixed for roughly seven hundred years.

💡 Teacher tip: For a "shared feature EXCEPT" question, build a quick two-column mental check: does this appear in the Tang section and in the modern section? If it appears in only one, that is your answer.

Answer: D

Framing: This is an "EXCEPT" question — three of the four options are arguments the author actually makes; one is invented. Your job is to find the option that has no anchor in the passage.

Why A is an argument the author makes: The passage says the French Revolution "ended not only with a reign of terror and the emergence of a newly rich ruling caste, but with a new adored emperor, Napoleon Bonaparte." The anarchists (whose view the author presents) held that workers and peasants were "inevitably betrayed by the new class of politicians, whose first priority was to re-establish a centralized state power." So the betrayal-by-politicians argument is squarely in the text.

Why B is an argument the author makes: The passage states directly, "For anarchists the state itself is the enemy," and then explains that "every state keeps a watchful and sometimes punitive eye on its dissidents" and that new rulers applied "violence and terror, a secret police, and a professional army to maintain their control." The core stance — the state is the enemy because it uses coercive control — is the author's.

Why C is an argument the author makes: The last paragraph opens, "There are, unsurprisingly, several traditions of individualist anarchism," and then describes strands (Stirner's "conscious egoism" and the American figures) that centre on "protecting our own autonomy." So C is supported.

Why D is NOT an argument the author makes: The passage never discusses a "popular perception" of anarchism as lawless or violent, and never attributes any such perception to a "mistrust of collectivism." The only thing close is the opening note that the word anarchy "was used in a derogatory sense until 1840" — but no cause is given, and collectivism is never linked to it. D introduces ideas the passage simply does not raise.

Answer: D

Framing: The passage defines the "betrayal" in a specific way. You need to find the option that restates how the new ruling class of politicians betrayed the workers and peasants.

What the passage says: Workers and peasants, "grasping the chance that arose to bring an end to centuries of exploitation and tyranny, were inevitably betrayed by the new class of politicians, whose first priority was to re-establish a centralized state power." The passage then adds that "the new rulers had no hesitation in applying violence and terror, a secret police, and a professional army to maintain their control."

So the betrayal has a clear shape: the politicians rose to power through the workers' revolutionary struggle, and then turned the coercive machinery of the state against those same workers.

Why D is correct: It captures both halves exactly — the new ruling class "rode to power on the strength of the workers' revolutionary anger" (the revolution was won by ordinary people) and "then turned to oppress that very class" (violence, terror, secret police, professional army).

Why the others fail:

• A is impossible: the anarchists opposed the ruling class and the state; they were not its members.
• B says the anarchists were too weak to stop the new rulers — even if true, it does not describe how the betrayal happened.
• C invents a power-sharing deal with the old ruling class; the passage never mentions any such arrangement.

Answer: D

Framing: You need both a similarity and a difference between American individualist anarchists and free-market liberals. The last two sentences of the passage give you both directly.

What the passage says: The American individualist anarchists "argued that in protecting our own autonomy and associating with others for common advantages, we are promoting the good of all." They "differed from free-market liberals in their absolute mistrust of American capitalism, and in their emphasis on mutualism."

So the shared ground is a commitment to individual autonomy. The divergence is that the anarchists pair that autonomy with mutualism — associating with others for common advantage — while free-market liberals do not; they embrace capitalism instead.

Why A is correct: It states the similarity ("both prioritise individual autonomy") and the difference ("the former also emphasise mutual dependence, while the latter do not") in exactly the terms the passage uses.

Why the others fail:

• B claims the anarchists favour a "people's state" — but anarchists reject the state entirely; this is invented.
• C says both are arguments for capitalism — the reverse of what the passage says: the anarchists had "absolute mistrust of American capitalism."
• D fabricates a foundation in altruism and a "mystical" market; nothing in the passage supports either claim.

Answer: A

Framing: Pick the set of concepts that best maps onto the passage's central, recurring concerns — not minor or one-off mentions.

What the passage is built around:

• Anarchism — the subject of the entire passage.
• The state — the recurring enemy: "For anarchists the state itself is the enemy," and anarchist-communism "differs from state socialism in opposing the concept of any central authority."
• The individual — the passage tracks individualist traditions that defend "our own autonomy."
• Freedom — the passage stresses "the obviously desirable freedom of an individual or family" and autonomy throughout.

Option A — Anarchism, State, Individual, Freedom — covers every one of these core axes.

Why the others fail:

• B includes "Strike," which the passage never discusses, and "Egoism," which is only a minor sub-tradition.
• C includes "Protection," which appears only in passing ("every state protects the privileges of the powerful"), and "Liberals," who appear only as a contrast at the very end.
• D captures betrayal and power, which are themes, but it drops the foundational individual/freedom axis that runs through the whole passage — including its opening (liberalism, autonomy) and its close (individualist anarchism).

Answer: A

Framing: Find the one idea shared by every strand of anarchism the passage describes — communist, collectivist, and individualist alike.

What unifies all the strands: Hostility to concentrated, centralised state power. The passage states plainly, "For anarchists the state itself is the enemy," and specifies that anarchist-communism "differs from state socialism in opposing the concept of any central authority." Even the individualist strands are defined by defending autonomy against the state. So opposition to the centralisation of power in the state is the common thread.

💡 Teacher tip: When a question asks what is common to all forms, test each option against the most collective strand and the most individualist strand. If it fails either, it is not universal.

Why B is correct: It restates the one position every strand in the passage shares — opposition to centralised state power.

Why the others fail:

• A is false: individualist anarchism derives from Stirner and from 19th-century American figures, not from Proudhon.
• C is false: anarchist-communism is collective — property is "held in mutual control by local communities" — so the primacy of the individual is not universal.
• D is a distractor that plays on the word "anarchic"; the passage clearly identifies shared ground, so "no common idea" contradicts the text.

Answer: B

The four sentences that belong together all orbit one idea: the feminist inquiry into reading — specifically, the realization that the literary canon is androcentric, and the critical work that flowed from that realization.

Let's build the chain link by link:

1. Sentence 1 opens with a broad framing: for feminists, how we read is tied to what we read. It introduces the topic without referring back to anything, so it works as the opening line. The phrase "what we read" quietly sets up the idea of the literary canon.

2. Sentence 5 narrows that framing: the feminist inquiry into reading begins with the realization that the literary canon is androcentric, and that this has a profoundly damaging effect on women readers. The opener "More specifically" signals a move from the general claim in 1 to the specific thesis. So 1 → 5.

3. Sentence 4 follows naturally: "The documentation of this realization was one of the earliest tasks undertaken by feminist critics." The phrase "this realization" hooks directly back to the realization named in 5 — that the canon is androcentric. So 5 → 4.

4. Sentence 2 completes the chain: "Elaine Showalter's critique of the literary curriculum is exemplary of this work." "This work" refers back to the documentation task described in 4. Showalter's critique is offered as a concrete example of that early feminist critical work. So 4 → 2.

The paragraph thus reads 1 → 5 → 4 → 2, held together by two pronoun hooks — "this realization" (linking 5 to 4) and "this work" (linking 4 to 2) — and by a logical movement from general framing, to specific thesis, to the task it generated, to a named example of that task.

Why sentence 3 is the odd one out:

Sentence 3 — "Androcentric literature structures the reading experience differently depending on the gender of the reader" — sounds related because it mentions "androcentric literature," but it makes a distinct claim. It argues that androcentric literature creates gendered reading experiences — that the same text is experienced differently depending on whether the reader is male or female. The coherent paragraph, by contrast, is about the realization that the canon is androcentric, the documentation of that realization, and a specific critic's example of that work. Sentence 3 has no pronoun hook (no "this realization" or "this work") into the chain, and its focus — how reading experience varies by gender — is a tangent to the paragraph's central thread.

💡 Teacher tip: In Odd-One-Out questions, the odd sentence often sounds topical because it reuses a keyword (here, "androcentric"). The real test is whether it fits the logical chain — look for pronoun hooks and demonstratives ("this," "such," "that") that tie sentences together. The sentence without a hook is usually the odd one.

Answer: 3

Let's build this paragraph link by link by following the logical thread — a problem, then a method, then a finding, then an elaboration of that finding.

Step 1 — Find the opener.

Sentence 1 introduces the topic and a difficulty: "Relying on narrative structure alone, indigenous significances of nineteenth century San folktales are hard to determine." There is no back-reference to any earlier sentence, no pronoun like "this" or "such" pointing to something before it. It sets up a problem, which makes it a natural opener.

Step 2 — What comes after the problem? The remedy.

Sentence 4 directly answers the difficulty raised in 1. If meaning is hard to determine from narrative structure alone, sentence 4 tells us how meaning can still be elicited — "by probing beneath the narrative of verbatim, original-language records and exploring the connotations of highly significant words and phrases." The flow is clean: Problem (1) → Method (4).

Step 3 — What does the method reveal?

Sentence 3 reports the result of that probing: "Selected tales reveal that they deal with a form of spiritual conflict…concern conflict between people and living or dead malevolent shamans." The word "reveal" signals a finding, and "selected tales" refers back to the San folktales under discussion. So the chain extends: Method (4) → Finding (3).

Step 4 — Elaborate the finding.

Sentence 3 has just introduced malevolent shamans as one side of a conflict. Sentence 2 now gives us the other side — benign shamans who "using their supernatural potency…transcend the levels of the San cosmos in order to deal with social conflict." The contrast between malevolent shamans (sentence 3) and benign shamans (sentence 2) is the glue that locks 3 before 2. The paragraph moves from naming the conflict to fleshing out the shamanic dimension of it: Finding (3) → Elaboration (2).

Reading the full sequence straight through:

• Narrative structure alone is insufficient to determine the indigenous significances of San folktales (1) →
• Meaning can be elicited by probing beneath the narrative and exploring key words and phrases (4) →
• This probing reveals the tales are about spiritual conflict involving malevolent shamans (3) →
• Benign shamans, using supernatural potency, counter such conflict and protect the community (2).

The thread — problem, method, finding, elaboration — holds without a break.

💡 Teacher tip: In para jumbles, watch for a problem–solution pair first; once you lock that, the sentences reporting results and elaborating them usually fall into place through pronoun and keyword echoes (here, malevolent → benign shamans).

Answer: 1432

Let's find the sentence that can open the paragraph — one that introduces the topic without referring back to anything earlier.

Step 1 — Identify the opener.

Sentence 3 says: "Since the 1990s, the security environment of South East Asia has seen both continuity and profound changes." This is a broad framing statement — it introduces the subject (South East Asia's security environment) and sets up two threads to unpack: continuity and profound changes. No pronoun or phrase looks back at a previous sentence, so it can stand first. The other sentences all feel like they are filling in something — sentence 4's "These concerns" clearly needs an antecedent, and sentences 1 and 2 read like examples of a trend already named.

Step 2 — Unpack the first thread: continuity.

Sentence 3 promises "continuity." Sentence 1 delivers exactly that: "Tensions and sometimes conflict remain an issue in and between the 11 states…" The word "remain" signals something that has persisted over time — that is the continuity. So 3 → 1.

Step 3 — Unpack the second thread: profound change.

Sentence 3 also promises "profound changes." Sentence 2 supplies that: "China's rise as a regional military power and its claims in the South China Sea have become an increasingly pressing security concern…" This is a new, escalating development — a change, not something that has merely persisted. So 1 → 2.

Step 4 — Close the chain with the pronoun link.

Sentence 4 says: "These concerns cause states from outside the region to take an active interest in South East Asian security." The phrase "These concerns" must refer to something plural just mentioned. The only fitting antecedent is sentence 2's "pressing security concern" — China's rise and its South China Sea claims. So 2 → 4 is locked.

Reading it straight through:

Since the 1990s, the security environment has seen continuity and change (3) → continuity: internal tensions among the 11 states remain (1) → change: China's rise becomes a pressing concern (2) → these concerns draw in outside powers (4).

💡 Teacher tip: When an opener names two abstract ideas (here, "continuity" and "change"), the sentences that follow usually unpack them in the same order — and a demonstrative like "These concerns" will anchor the final sentence to the most recently mentioned noun.

Answer: 3124

Let's build this paragraph link by link, watching for the chronological thread and the pronoun references that tie the sentences together.

Step 1 — Find the opener

Sentence 1 is the natural opener: "Man has used poisons for assassination purposes ever since the dawn of civilization…" It sets the broadest historical stage — antiquity — and contains no back-reference to any earlier sentence. No other sentence can start the paragraph, because each of them points back to something.

Step 2 — What follows the broad historical stage?

Sentence 3 takes us forward in time and scope: "The foundation of microbiology by Louis Pasteur and Robert Koch offered new prospects for those interested in biological weapons…" We move from poisons used since antiquity (1) to 19th-century science creating a new, more systematic kind of threat. This is a clean chronological and logical step — 1 → 3.

Step 3 — The pronoun link that locks the next pair

Sentence 2 begins with "These dangers were soon recognized…" The word "These" must refer to something just mentioned — and the only candidate is the new prospects for biological weapons described in sentence 3. Those new capabilities created the dangers that were then recognized, leading to the 1874 Brussels and 1899 Hague declarations prohibiting poisoned weapons. So 3 → 2.

Step 4 — Close the paragraph

Sentence 4 says "Though treaties were all made in good faith, they contained no means of control, and so fail[ed]…" The word "treaties" refers directly to the two international declarations (1874 and 1899) named in sentence 2. Sentence 4 comments on the weakness of those treaties — a natural concluding thought. So 2 → 4.

Reading the full chain

1. Poisons used since the dawn of civilization → 3. Microbiology created new, rational biological-weapons prospects → 2. These dangers were recognized, leading to 1874/1899 prohibitions → 4. But those treaties lacked enforcement and failed.

The sequence flows from broad history → scientific development → international response → evaluation of that response.

💡 Teacher tip: In para jumbles, demonstrative pronouns like "these" and noun echoes like "treaties" are the strongest binding signals. Always ask: what specific noun or idea does this word point back to?

Answer: 1324

The passage argues that movies and television shows create unrealistic expectations about the reliability of forensic phonetics (the "science of voices"), which in turn leads to errors in real-life justice—a phenomenon known as the "CSI effect."

Let's evaluate the options:

1. Option C correctly identifies both the source of the problem (movies and television) and the effect it creates (the false belief that forensic phonetics is robust and foolproof). This directly aligns with the passage's main point about the "CSI effect."

2. Option A only states that the scientific basis of voice recognition can be shaky. While true, it completely drops the passage's primary focus: the role of movies and television in creating this misimpression.

3. Option B misreads the passage. The author is not saying that the specific techniques shown in movies are actually used to identify criminals in real life. Rather, the point is that movies create false expectations about what the science can achieve.

4. Option D reverses the causation. The passage does not claim that voice recognition is used in real investigations because of movies. Instead, it argues that movies distort people's beliefs about the reliability of investigations that are already happening.

Answer: C

The passage traces Europe's response to a shifting world order: as Soviet power waned and the world turned multipolar, Europe redefined itself by setting aside centuries-old political mechanisms, adopting a common currency (2002), and creating a formal political structure (2004) — all to unify and manage differences peacefully.

Main point and scope: Europe deliberately reduced its internal differences — politically and economically — in order to adapt to an emerging multipolar world (with German unification as an added push).

Why D works: "Lower political and economic heterogeneity" neatly captures both concrete moves in the passage — the common currency (economic) and the formal political structure (political). "In order to adapt itself to an emerging multi-polar world" preserves the motive the passage explicitly states. Both the act and the reason are present.

Why the others fall short:

1. A — "Consistently changed… culminated in a united Europe" is too vague. It gestures at change but drops the specific idea of lowering heterogeneity through a currency and political union, and it doesn't tie the change clearly to the multipolar trigger.
2. B — Captures only the political structure and only one driver (German unification). It omits the common currency entirely and reduces the broader "adapt to a multipolar world" framing to a single cause.
3. C — Again, "consistently changed its internal structure" is generic. It misses the specific act of reducing political and economic heterogeneity and doesn't foreground the multipolar motive.

💡 Teacher tip: When a passage pairs a specific action (currency + political union) with a stated motive (adapt to multipolarity), the correct summary must keep both. Options that stay at a vague "changed/adapted" level are usually incomplete.

Answer: D

The passage sets up a contrast: for decades, psychologists held that intelligence is a largely innate, hereditary, measurable trait — and then biologists began challenging that view on two specific fronts.

What are the two prongs of the biologists' critique?

1. They question whether it even makes sense to speak of a single entity called "intelligence."
2. They question the validity of the measures used to estimate its heritability, since humans — unlike plants or animals — are not bred under controlled conditions.

A good summary must capture both prongs and correctly name biologists as the challengers.

Option A does exactly that: it states that biologists have questioned (i) the long-standing view that intelligence is a single entity, and (ii) the attempts to estimate its heritability. Both prongs are present, and the actor is correct.

Why the others fall short:

• Option B is too vague. It only says biologists criticised the idea that people are "born with more or less intelligence potential" — a generic restatement of the conventional view. It drops the two specific challenges (single-entity coherence and heritability-measure validity) that are the heart of the biologists' contribution.

• Option C collapses the critique into a broad phrase — "measurable immutable characteristic." While not entirely wrong in spirit, it loses the specific single-entity challenge and the heritability-measure challenge. It blurs the passage's precise two-pronged argument into a general complaint.

• Option D starts well by mentioning the single-entity challenge, but then trails off into an incomplete, garbled phrase ("the ways in which what is inherited"). The sentence doesn't meaningfully capture the second prong and reads as truncated.

Answer: A

Odd-One-Out — Slave Talk

Step 1 — Read for the common thread.

Four of the five sentences are clearly circling one idea: slave talk as a subversive force within the institution of slavery — impossible to mute, and feared by owners. Once you sense that thread, the sentence that leaves it becomes visible.

Step 2 — Build the coherent chain.

1. Sentence 4 opens with the framing paradox: freedom of speech and the power to silence were markers of white liberty in the colonies, yet slavery itself "depended on dialogue" — slaves could never be completely muted. This sets up the tension the rest of the paragraph explores.

2. Sentence 1 develops that tension: talk was the most common way enslaved men and women subverted the rules of bondage and gained more agency than they were supposed to have. The phrase "subvert the rules" flows directly from 4's claim that slaves could not be muted.

3. Sentence 2 elaborates on the nature of that talk: even under extreme violence and unfreedom, their words remained "ubiquitous, ephemeral, irrepressible, and potentially transgressive." The word "irrepressible" echoes "could never be completely muted" from 4, and "transgressive" echoes "subvert" from 1.

4. Sentence 5 closes the paragraph by shifting to the owners' perspective: slave-owners obsessed over slave talk, could never control it, and feared its power to "bind and inspire" — because oaths, whispers, and secret conversations bred conspiracy and revolt. This is the natural consequence of everything said in 4-1-2: if slave talk is irrepressible and subversive, owners will fear it.

So the coherent paragraph runs 4 → 1 → 2 → 5: paradox → subversion → irrepressibility → owners' fear.

Step 3 — Identify the odd sentence.

💡 Teacher tip: In an OIO set, the odd sentence usually doesn't contradict the others — it simply changes the subject or the dimension being discussed.

Sentence 3 shifts to a different dimension entirely: "Slaves came from societies in which oaths, orations, and invocations carried great potency…as a connection to the all-powerful spirit world." This is about the slaves' African societies of origin and the spiritual potency of speech there. It has no pronoun hook into the chain, no logical bridge to the colony-level discussion of talk-as-subversion, and it introduces the spirit world — a topic none of the other four sentences touch. It breaks the unity of the paragraph.

Answer: 3

What this question tests

This is an EXCEPT question, so three of the four options must be inferable from Le Boeuf's study as described, and one must either contradict the passage or go beyond what the study supports. The safest method is to check each option against the specific claims the passage attributes to Le Boeuf.

Why A, B, and D can be inferred

• A follows from the origin story of the dialects. The passage explains that all living northern elephant seals descend from the tiny herd that survived near-extinction on Isla Guadalupe, and that dialects arose because "the dialects were, perhaps, a result of isolation over time, after the breeding sites had been recolonized." Without the nineteenth-century bottleneck, there would have been no small founder groups and no isolation-driven divergence — so no dialects. A is inferable.

• B is directly supported: "At the individual level, the pulse of the calls stayed the same: A male would maintain his vocal signature throughout his lifetime." So population and migration could shift the average without altering any one male's pulse rate. B is inferable.

• D follows from two facts working together: Le Boeuf found that at Año Nuevo "the pulse rate increased," and the long-run trend he and Petrinovich predicted was that "the calls in all locations would have eventually regressed to the average pulse rate of the founder colony." So the average at Año Nuevo was rising toward that founder norm, which is consistent with D.

Why C cannot be inferred

C claims the influx of immigrants would soon make Año Nuevo's pulse rate exceed that of Isla Guadalupe. The passage says the opposite on both counts:

• The rate rose "but it still remained relatively slow compared to the other colonies."
• The model predicts movement toward the founder colony's average — convergence, not overshoot.

Nothing in Le Boeuf's study supports Año Nuevo's rate crossing past Isla Guadalupe's. C is the claim that does not follow.

Answer: C

What this question tests

This is a hypothetical-condition question. To answer it, first pin down why the dialects disappeared, then ask which condition would have blocked that cause.

Why the dialects disappeared

The passage gives a two-part mechanism:

1. Immigrants arrived carrying a different tempo. At Año Nuevo, for example, 43 percent of males in the early 1970s "had come from southern rookeries that had a faster pulse rate," and the average pulse rate rose.
2. Individual seals never changed their own calls: "A male would maintain his vocal signature throughout his lifetime."

So immigrants kept their original tempo, and because they joined the local population, they pulled each colony's average toward the founder colony's norm. Over time, "the calls in all locations would have eventually regressed to the average pulse rate of the founder colony," and the regional differences vanished.

What would keep a dialect alive?

A dialect persists only if the local average stays distinct. That requires immigrants not to perturb it — which means immigrants would have to adopt the residents' tempo rather than import their own.

💡 Teacher tip: The key insight is that the dialect died because individuals never adapted. Anything that makes individuals adapt to their new colony protects the dialect; anything that keeps them rigid or adds more same-tempo migrants does not.

Answer: D

What this question tests

A summary of the overall transformation must capture every axis on which the calls changed — not just one. Before choosing, pull the "then" and "now" descriptions straight from the passage.

Then (about 50 years ago)

• "The drumming pattern was quite simple."
• Dialects "denoted just a change in tempo" — so there was great regional variety.
• Individual males kept one signature for life, and the variation the scientists cared about was between colonies, not within them — so less individual variety.

Now

• "Modern males exhibit more individual diversity" — great individual variety.
• "Their calls are more complex," "sometimes featuring doublets or triplets" — complex composition.
• The geographical dialects "had vanished" — less regional variety.

So the full arc is:

simple composition, less individual variety, great regional variety → complex composition, great individual variety, less regional variety.

That is exactly option B.

Why the others fail

• A tracks only the pulse-rate increase and ignores the changes in composition and individual variety that are central to the "transformation."
• C reverses the composition axis, calling the old calls complex and the new ones simple — the opposite of what the passage says.
• D reverses the individual-variety axis, claiming the past had great individual variety and the present has less — again the reverse of "modern males exhibit more individual diversity."

Answer: B

What this question tests

We need the cause of the faster pulse rate in the southern rookeries. The passage does not state it in so many words for the south specifically, but it gives a general founder-effect explanation for why different colonies had different tempos.

The mechanism the passage gives

Le Boeuf and Petrinovich concluded that the dialects were "a result of isolation over time, after the breeding sites had been recolonized," and they spelled out the chance-settler logic:

"At other sites, where the scientists found faster pulse rates, the opposite would have happened — seals with faster rates would have happened to arrive first."

The southern rookeries are precisely such "other sites" — they had faster pulse rates. So the passage's own explanation is that faster-pulse seals from the original Isla Guadalupe population happened to be the first settlers of those rookeries. That is option A.

Why the others fail

• B says many males migrated from the southern rookeries to Año Nuevo. That is true and is mentioned, but it explains why Año Nuevo's average rose — not why the southern rookeries themselves were fast in the first place. It answers a different question.
• C suggests Año Nuevo males recolonised the south. But Año Nuevo was the slowest-pulse colony; its migrants would have made the south slower, not faster — the opposite of what we see.
• D links the fast tempo to doublets and triplets. Those are a modern feature of call complexity, described for current males generally; the passage never ties them to the historical pulse-rate difference at the southern rookeries. This mixes up two separate findings.

Answer: A

Framing: This question uses a double negative — "if false, could support" — so you need to find the statement whose negation supports the passage. In other words, which option, as written, contradicts what the passage argues?

Unpacking the logic:

• If a statement as written already agrees with the passage, then making it false would weaken the passage, not support it.
• If a statement as written contradicts the passage, then making it false would support the passage.
• If a statement is simply irrelevant, its truth or falsity does nothing for the argument.

So we are looking for the option that goes against the passage.

Why D is correct:

"Perish the thought that X" means "let X be rejected" — i.e., "X is not the case." So option D effectively says: complete sentences do not necessarily need nouns and verbs.

The passage directly contradicts this. It states that a sentence is "by definition, a group of words containing a subject (noun) and a predicate (verb)." Nouns and verbs are called "the two indispensable parts of writing."

So D as written clashes with the passage. If D is false — meaning complete sentences do need nouns and verbs — the passage's central claim is supported. That is exactly what the question asks for.

Why the others fail:

Answer: D

Framing: You need to match the logical structure of the quoted lines, not just their surface wording. Identify the pattern, then find the option that preserves it.

What is the pattern?

The quoted lines say: take any member of one category (a noun), combine it with any member of another (a verb), and the result is guaranteed to be a valid sentence — "It never fails." The examples ("Rocks explode. Jane transmits. Mountains float.") are deliberately odd, yet each is still a perfect sentence.

So the structure is:

Any X + any Y → a guaranteed valid result of type Z.

The key features to preserve:

1. "Any" — no restriction on which member you pick.
2. Two different ingredients combined.
3. The result is automatically valid — it cannot fail.

Why A is correct:

"Take any vegetable, put some spices in it, and you have a dish" preserves all three features: any vegetable, plus spices, reliably yields a dish. The result is guaranteed regardless of which vegetable you choose. This mirrors "Take any noun, put it with any verb, and you have a sentence."

Why the others fail:

• B — "Take an apple tree, plant it in a field, and you have an orchard." A single tree does not make an orchard; it makes a planted tree. The result is not guaranteed — the structure breaks down.
• C — "A group of nouns arranged in a row becomes a sentence." This uses only one ingredient (nouns) and omits verbs entirely. The passage explicitly says a sentence needs both a noun and a verb, so this contradicts the very rule being illustrated.
• D — "A collection of people with the same sports equipment is a sports team." Merely holding the same equipment does not make a team — shared purpose, organization, and roles are needed. The result is not automatic.

💡 Teacher tip: When a question asks for a "similar" statement, isolate the logical skeleton — the guarantees and the ingredients — not the topic.

Answer: A

Framing: A main-concern answer must capture the whole arc of the passage, not just one true line. Trace the argument end to end before choosing.

What is the passage really about?

The passage opens by establishing that communication depends on shared grammatical rules: "When these rules break down, confusion and misunderstanding result. Bad grammar produces bad sentences." Everything that follows — the noun-verb foundation, the permission to break rules only when certain, grammar as a safety net, grammar as a "pole" to get thoughts walking — is in service of avoiding that failure. The stakes are set early: grammar matters because bad grammar produces bad sentences.

Why B is correct:

"Bad grammar produces bad sentences" states the thesis that frames the entire piece. It captures the concern — the why behind everything the author teaches — rather than any single technique.

Why the others fail:

• A — "The telling clause here is Unless he is certain of doing well." This is a pointed sub-clause the author highlights within one example. It matters, but it is a supporting detail, not the overarching concern.
• C — "Strunk and White caution against too many simple sentences in a row, but simple sentences provide a path…" This is a secondary aside about technique — a means of staying safe, not the main worry driving the passage.
• D — "Nouns and verbs are the two indispensable parts of writing…" This is a key teaching point, but it is the foundation the author uses to address his concern, not the concern itself. It answers "how," while B answers "why."

Answer: B

Framing: You need the one statement that does not follow from the passage. Three options are inferable; one is not. Check each against what the text actually says or implies.

Why C is correct (the exception):

Option C claims "the primary purpose of grammar is to ensure that sentences remain simple." The passage never says this. Grammar is described as the system that organises communication and prevents "confusion and misunderstanding." Simple sentences are offered as a "safety net" — a refuge when a writer fears getting lost — not as grammar's purpose. Moreover, the passage explicitly catalogues complex structures (appositives, compound-complex sentences, modifying phrases) as part of grammar's domain. Nothing frames simplicity as grammar's goal.

Why the others are inferable:

• A — "Sentences do not always have to be complete." The author asks, "Must you write complete sentences each time, every time? Perish the thought," and adds that "the Grammar Police aren't going to come and take you away." So incompleteness is sometimes acceptable. Inferable.
• B — "The subject-predicate relation is the same as the noun-verb relation." The passage defines a sentence as "a group of words containing a subject (noun) and a predicate (verb)," directly equating subject with noun and predicate with verb. Inferable.
• D — "'Grammar Police' is a metaphor for critics who focus on linguistic rules." The phrase appears in "the Grammar Police aren't going to come and take you away," a playful image of enforcers who would punish rule-breaking. That is exactly a metaphor for rule-obsessed critics. Inferable.

💡 Teacher tip: When a question asks for the non-inferable statement, watch for options that take a true detail and inflate it into a false general claim — here, "simple sentences help" becomes "simplicity is grammar's purpose."

Answer: C

Framing: Pin down the author's values first, then test each practice against them. The author is not anti-rule nor anti-creativity — he wants writers to know the rules so they can tell good writing from bad, and to break them only when certain.

What does the author value?

• Writers need "a rudimentary grasp of how the parts of speech translate into coherent sentences" so they can know whether they are "doing well."
• Grammar is "the pole you grab to get your thoughts up on their feet and walking" — a helpful support, not a cage.
• Rule-breaking is allowed, but only when the writer is "certain of doing well."

So the author would support anything that helps writers understand and apply the standard rules of grammar as an aid.

Why A is correct:

"The availability of language software that will standardise the rules of grammar as an aid to writers" aligns with the author's stance. A tool that helps writers grasp and follow the rules — so they can judge their own work — is exactly the kind of support the author endorses. It treats grammar as a helpmate, which matches "the pole you grab."

Why the others fail:

• B — "A campaign demanding that a writer's creative license should allow the breaking of grammatical rules." The author does not grant a blanket license to break rules. He permits it only when the writer is "certain of doing well." A campaign demanding freedom from rules goes further than the author would accept.
• C — "A Creative Writing course that focuses on how to avoid the use of rhetoric." The author is not against rhetoric. He recommends simple sentences as a refuge from rhetorical tangles when a writer feels lost — not the elimination of rhetoric. He himself uses and appreciates complex structures.
• D — "The critique of standardised rules of punctuation and capitalisation." The author upholds the rules as the baseline: sentences "begin with a capital letter, end with a period," and grammar rules exist to prevent confusion. He would not support dismantling standardised rules.
