CAT 2017 VARC Questions — Slot 2

This paragraph is about a defence mechanism: caterpillars that whistle to scare off birds. But the core idea isn't just "they whistle" — it's why the whistle works. Let's pin down the main point before checking the options.

Main point of the passage: The caterpillars defend themselves by producing whistles that mimic bird alarm calls — an auditory trick, or acoustic deception. The passage walks us from the old theory (birds were merely startled by loud noise) to the newer, better-supported one (the whistle specifically imitates an alarm call, sending predators to cover).

Now let's test each option against that main point:

1. Option A — Two problems. First, "periodically" suggests they whistle on a regular schedule, but the passage says they whistle when pecked by a bird — it is a triggered response, not a routine. Second, "specialized vocal tract" is factually wrong: the caterpillars force air through holes in their sides; they do not have a vocal tract. So A distorts both the timing and the mechanism.

2. Option B — This only captures the loudness of the whistle and the surprise that such a small insect can be so loud. That detail is in the passage, but it is a supporting fact, not the main idea. The central claim — that the whistle mimics a bird alarm call for defence — is completely missing. B is true but beside the point.

3. Option C — This captures both the mechanism (whistles that mimic bird alarm calls) and the purpose (defence), and it correctly labels the trick as acoustic deception — sound-based, which matches the passage exactly. This is the full main point in one line.

4. Option D — This starts well by calling it deception, but then adds "camouflage." Camouflage is a visual trick — blending in or looking like something else visually. The passage describes an auditory trick: a whistle that sounds like an alarm call. Nothing in the passage supports visual camouflage, so D introduces an unsupported element.

💡 Teacher tip: When a summary option adds a word the passage never supports (like "camouflage" here), treat it as a red flag — even if the rest of the option looks right, one unsupported claim is enough to reject it.

The option that captures the main point without distortion is C.

Answer: C

Framing: This is an EXCEPT question — three of the four options are reasons the passage does give for cities promoting creativity; one is not. Find the one the passage never claims.

The passage attributes cities' creative power to four concrete things, all packed into one sentence:

"With their diverse populations, dense social networks, and public spaces where people can meet spontaneously and serendipitously, they spark and catalyze new ideas. With their infrastructure for finance, organization and trade, they allow those ideas to be swiftly actualized."

Let's match each option against those four:

For the author, the engine of urban creativity is social interaction plus economic infrastructure — people meeting each other, plus the organizational machinery to make ideas real. Nowhere does the passage say cities boost creativity by offering cultural activities (concerts, museums, performances, etc.). That sounds plausible in real life, but it is simply not one of the reasons this passage gives.

Answer: D

Framing: A word-in-context question. Ask yourself: what reversal or surprise does the word ironic point to in that sentence?

Here is the line:

"As for what staunches creativity, that's easy, if ironic. It's the very institutions that we build to manage, exploit and perpetuate the fruits of creativity — our big bureaucracies, and sad to say, too many of our schools."

The irony is a reversal of expectation. We would expect that the institutions we built around creativity — to manage it, exploit it, and keep its benefits flowing — would protect and extend creativity. Instead, those very institutions are what kill it. The thing created to serve creativity becomes the thing that destroys it. That is the irony.

That is exactly option B: institutions created to promote creativity eventually stifle it.

Why the others fail:

• A (people need social contact, not isolation) is a true idea elsewhere in the passage, but it is not the irony being flagged here. It does not describe any reversal.
• C (the larger the creative population, the more likely it is to be stifled) is never said — the passage never links a city's creative population size to its likelihood of being stifled.
• D (bureaucracies are the inevitable outcome of successful cities) misreads the line. The author is not saying bureaucracies inevitably follow cities; he is saying the institutions built around creativity end up suppressing it.

Answer: B

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

The argument moves through these stages:

1. Creativity is innate in every human being.
2. Yet it is fundamentally social — it flourishes where creative people meet, compete, and collaborate, which is why cities are its natural home.
3. It is stifled by the very institutions (bureaucracies, schools) that regiment and standardize human interaction.
4. Even so, creativity itself is flourishing — the real problem is that its benefits are unevenly spread.

The spine holding all of this together is that creativity is nurtured through social interaction and killed when that interaction is suppressed or regimented. Option A — social interaction is necessary to nurture creativity — captures that spine.

💡 Teacher tip: A central idea is the thread that runs through every paragraph. If an option matches only one paragraph, it is a detail, not the center.

Why the others fail:

• B (creativity is gradually declining in all societies) overreaches. The 1968 study shows decline as children pass through schooling, not a universal decline across all societies.
• C (the creativity divide is widening with socio-economic trends) is a detail from one paragraph, not the whole argument's center.
• D (more people should work in creative jobs) is a policy recommendation the author never actually makes.

Answer: A

Framing: This is an inference question. Read what Jane Jacobs actually says, and connect it to the point the author has already made about institutions in the previous paragraph.

The author asks Jacobs what makes some places more creative than others. Her answer:

"All cities, she said, were filled with creative people; that's our default state as people. But some cities had more than their shares of leaders, people and institutions that blocked out that creativity. She called them 'squelchers.'"

So Jacobs's logic is:

• Every city starts with the same raw material — creative people are the default.
• What separates the more-creative cities is not that they have more creative people to begin with, but that they have fewer leaders and institutions blocking that creativity.

In other words, the cities that stay creative are the ones whose leaders and institutions do not get in the way. That is option C.

Why the others fail:

• A (they have to struggle to retain creativity) — Jacobs is describing what makes a city creative, not claiming it must constantly struggle.
• B (they must 'squelch' unproductive people and promote creative ones) reverses the logic. "Squelching" is precisely the thing that kills creativity; Jacobs calls the blockers "squelchers," not the solution.
• D (they typically do not start off as creative hubs) contradicts Jacobs — she says all cities are filled with creative people by default.

Answer: C

Framing: When a passage cites a study, ask what claim is the study being used to support? Look at the sentence the study is attached to.

The study is introduced right after this claim:

"Creativity is disruptive; schools and organizations are regimented, standardized and stultifying."

Then the author presents the falling test scores: 98% of 3–5-year-olds pass, but only 32% of 8–10-year-olds, 10% of 13–15-year-olds, and just 2% of 25-year-olds. The steady collapse of those scores as children grow older and move through school is offered as evidence that schooling suppresses creative thinking. That is option B.

Why the others fail:

• A (children learn to be more creative as they get older) says the opposite of what the data shows — the scores fall with age.
• C (the more children learn, the less creative they become) sounds close, but it swaps the target. The passage indicts institutional regimentation — the standardized, stultifying nature of schools — not learning itself. For this author, schooling and learning are not the same thing.
• D (technology prevents creativity) introduces something the passage never mentions.

Answer: B

Framing: This asks for the assumption behind the author's ranking of "creative cities." An assumption is an unstated premise the argument must rely on to work — find the buried premise that makes the ranking possible.

Look at how the author counts creative people in paragraph 6:

"…roughly a third of us… are able to do work which engages our creative faculties to some extent, whether as artists, musicians, writers, techies, innovators, entrepreneurs, doctors, lawyers, journalists or educators — those of us who work with our minds. That leaves a group that I term 'the other 66 percent,' who toil in low-wage rote and rotten jobs…"

Notice the dividing line the author draws: creative work = work done "with our minds"; the rest are "low-wage rote" jobs. For this ranking to mean anything, the author must be treating mind-work as creative and hand/manual work as not creative. If manual work counted as creative, the whole ranking would change. That buried premise — that people who work with their hands are not doing creative work — is the assumption the conclusion rests on. That is option A.

💡 Teacher tip: To spot an assumption, ask: what would have to be true for this argument to even work? The thing the author takes for granted without stating is the assumption.

Why the others fail:

• B (more than half the population works in non-creative jobs) is a consequence of the author's framework, not the assumption behind it.
• C (only artists, musicians, etc. should be valued) is far more extreme than anything the author claims — he lists many professions, and never says only artists matter.
• D (cities ignore or waste the creativity of low-wage workers) is a critique the author might sympathize with, but it is not the assumption on which the ranking is built.

Answer: A

Let's build this paragraph link by link.

Step 1 — Find the opener

Sentence 2 is the natural opener because it defines the placebo effect for the reader. It also plants a timeline marker — the effect "used to be regularly dismissed by researchers as a psychological effect." No other sentence can start, because every other sentence assumes we already know what the placebo effect is.

Step 2 — Follow the timeline from "used to be" to "now"

Sentence 2 says placebos used to be dismissed. Sentence 5 picks up that thread with the contrasting word "now": placebos are now studied "not just as foils for 'real' interventions but as a potential portal into the self-healing powers of the body."

So the link is: 2 → 5.

Step 3 — Elaborate on "self-healing"

Sentence 5 introduces the idea of the body's self-healing powers. Sentence 4 expands exactly that idea: the mind can "trigger biochemical changes" through belief, which "could empower chronic patients through the notion of our bodies' capacity for self-healing."

So: 5 → 4.

Step 4 — The pivot with "however"

Sentence 4 explains the belief mechanism. Sentence 3 then qualifies it: "The placebo effect is not solely based on believing in treatment, however, as the clinical setting in which treatments are administered is also paramount." The word "however" signals this pivot from belief to setting.

So: 4 → 3.

Step 5 — The pronoun "This" ties to the clinical setting

Sentence 1 opens with "This has huge implications for the health care system…" The "This" refers back to sentence 3's claim that the clinical setting is paramount. If the setting matters, then a system where patients get "minimal care or concern" from doctors has real consequences — which is exactly what sentence 1 spells out.

So: 3 → 1.

Final sequence

2 → 5 → 4 → 3 → 1

💡 Teacher tip: In para jumbles, watch for timeline pairs ("used to be" → "now"), concept echoes ("self-healing" → "self-healing"), and pivot words ("however") — they are the strongest adjacency signals.

Answer: 25431

Let's first pin down what the paragraph is actually arguing.

The author opens by saying language is slippery, liquid, gelatinous — it changes shape to fit its context. Wittgenstein's point follows: meaning has no sharp boundary, and the only real way to find a word's meaning is to look at how it is used. This is the "meaning is use" doctrine.

The paragraph then contrasts this with the dictionary-first view. A dictionary looks like it fixes meaning — the way pinned butterflies look permanent, or the way a gold standard looks like it backs a currency. But Wittgenstein found that in ordinary language, meaning is a free-floating currency: the value of each word arises out of exchange. The lexicographer then abstracts a meaning from that exchange and freezes it into a definition.

So the author's position is clear in its direction: meaning is dynamic and lives in use; definitions are static abstractions pulled out of that use. Definitions are derived from usage — not the other way round.

• Option C captures exactly this: meaning is dynamic, definitions are static, and definitions are culled from meaning-in-exchange rather than vice versa. That is the paragraph's thesis stated faithfully.

• Option A overstates the case. The author's "gold standard" analogy is about how definitions back or fix meaning — it is not a charge that definitions are "dogmatic" or purely "artificial." The passage is more measured than that.

• Option B flips the author's stance. It treats "meaning in use" as a problem that lexicographers must then fix — but the passage presents "meaning in use" as the correct, Wittgensteinian insight, not a difficulty to be corrected.

• Option D also reverses the position. It praises dictionary meaning as "less dangerous and ambiguous," implying fixed definitions are superior. The passage actually favours the dynamic, exchange-based view and treats the dictionary's fixity as a useful abstraction, not a safer alternative.

Answer: C

Framing: A purpose question asks for the organising thesis of the whole passage — not the opening hook, and not any single supporting detail. Trace the argument end to end before choosing.

The passage opens with a familiar image — nestling under a blanket — and uses it to introduce the subnivium, calling it "the most important ecosystem that you have never heard of." So far that sounds like a simple introduction. But the argument pivots at the end of the second paragraph:

"Consequently, disruptions to the subnivium brought about by climate change will affect everything from population dynamics to nutrient cycling through the ecosystem."

That sentence is the hinge. Everything after it — the depth-and-density mechanics, the shorter snow season since 1970, rain-on-snow raising density and killing insulation, the crowberry and alpine azalea examples, the field experiments showing root damage — is marshalled to show how climate change destabilises the subnivium and how that disruption ripples outward. The introduction of the subnivium is the setup; the climate-change argument is the payoff.

Why C is correct: It captures that organising purpose — the passage exists to outline what climate change does to the subnivium.

Why the others fail:

Answer: C

Framing: An EXCEPT question asks you to find the one statement the passage does not support. Check each option against the text — three are confirmed true, one is not.

Let us test each option:

• A — Snow depth and snow density both influence stability. Confirmed. The passage states plainly that "the stability of the subnivium depends on the interaction between snow depth and snow density." True.

• C — The subnivium holds a steady temperature that can be 30 to 40 degrees warmer than winter air. Confirmed. The passage says the subnivium "holds steady at around 32 degree Fahrenheit" and that this "can often be 30 to 40 degrees warmer than the air temperature during the peak of winter." True.

• D — Researchers have established adverse effects of dwindling snow cover. Confirmed. The passage describes field experiments in which researchers removed snow cover and found "damage to plant roots and sometimes even the death of the plant," and it ties shrinking snow seasons to a colder, more variable subnivium. True.

• B — Climate change has some positive effects on the subnivium. The passage acknowledges that warmer winters might seem beneficial for species that struggle in subzero cold, but it immediately undercuts this: "as with most ecological phenomena, the consequences are not so straightforward." Every concrete effect described — shorter snow season, rain-on-snow raising density, reduced insulation, a colder and more variable subnivium, root damage, plant death — is negative. The author never asserts a genuine positive effect on the subnivium itself.

Since B is the statement the passage does not support, it is the EXCEPT.

Answer: B

Framing: This question asks you to infer which action the author would endorse, given the argument the passage actually makes. Match the remedy to the cause the author emphasises — not to a detail that merely sounds related.

The passage's central claim is that climate change destabilises the subnivium, and that this disruption cascades through the ecosystem — affecting "everything from population dynamics to nutrient cycling." The author identifies the climate driver as the root problem: warmer winters shorten the snow season, rain-on-snow raises density and kills insulation, and the subnivium grows colder and more variable. The logical action consistent with that argument is to address the climate cause itself.

Why B is correct: Government action to curb climate change targets the root cause the author actually blames for the subnivium's decline.

Why the others fail:

• A — Using snow machines to guarantee eight inches treats a symptom, not the cause. The passage never endorses artificial snow as a solution; it argues that the climate-driven disruption of snow depth and density is the problem.
• C — Adding nutrients to the soil is never proposed. The passage mentions nutrient cycling as a consequence of subnivium disruption, not as something to be manually supplemented.
• D — Planting shrubs sounds tempting because crowberry and alpine azalea appear later in the passage. But those shrubs are offered as an example of interrelated factors, not as a recommended remedy. The author's emphasis is on the climate cause, not a shrub-planting fix.

💡 Teacher tip: When a question asks what an author would support, look for the action that matches the cause the author identifies — not an option that borrows a detail from the passage but applies it in a way the author never advocates.

Answer: B

Framing: A "these examples demonstrate" question asks why the author placed a specific illustration at that point in the argument. Look at what the surrounding sentences are arguing, then ask what the example proves.

Paragraph 6 opens with "The effects of a colder subnivium are complex" and then gives the crowberry and alpine azalea example. The passage explains that these shrubs "tend to block the wind and so retain higher depths of snow around them", which "helps to keep soils insulated and in turn increases plant decomposition and nutrient release." The field experiment that follows — removing snow cover and finding root damage and plant death — reinforces the same point: the subnivium's stability is not controlled by snow alone. Vegetation on the forest floor shapes how snow is caught, held, and structured, which in turn shapes the insulation below.

So the examples demonstrate that the subnivium's stability depends on several interrelated factors — snow depth, snow density, and the shrubs on the forest floor that help trap and structure the snowpack.

Why D is correct: It states exactly that — the shrubs are one of several interlinked factors governing subnivium stability.

Why the others fail:

• A — That species survive frigid temperatures is a general fact mentioned earlier in the passage, but it is not what the crowberry and alpine azalea example is used to prove here.
• B — The passage never claims that surviving species tend to be shrubs rather than trees. That is an idea the text does not raise at all.
• C — The abundance of these shrubs in temperate and Arctic regions is never discussed; the example is about their functional role in snow retention, not their prevalence.

Answer: D

Framing: An inference must follow strictly from what the passage says — no outside knowledge, no leap beyond the text. Eliminate anything the passage never compares, never claims, or overstates.

The key sentence is the thesis in the second paragraph:

"Consequently, disruptions to the subnivium brought about by climate change will affect everything from population dynamics to nutrient cycling through the ecosystem."

The author is saying that a change to one component — the subnivium — sends effects cascading through the wider ecosystem: populations, nutrient cycling, plant survival, decomposition. That licences exactly one inference: in this system, altering one element produces ripple effects across the others.

Why A is correct: It restates that inference in general terms — change one element in an ecosystem, and the effects spread through the rest.

Why the others fail:

• B — The passage discusses only temperate and Arctic regions. It never compares them with equatorial or arid regions, so we cannot infer that climate change hits the former harder.
• C — The blanket analogy is illustrative — it explains how air pockets trap heat. The passage never compares wool and goose down as materials, so this inference is unsupported.
• D — The word "only" makes this too strong. The passage says many organisms in temperate and Arctic regions depend on the subnivium, but it never claims the loss would affect only those regions.

Answer: A

Framing: A device question asks what rhetorical job an image is doing. Ask: why did the author choose blankets specifically, and what does the image set up?

The first paragraph opens with the sensory experience of nestling under a blanket — the warmth, the reluctance to leave the "warm refuge." But the author is not interested in blankets for their own sake. The very next move is the parallel: "Many plants and animals similarly hunker down, relying on snow cover for safety from winter's harsh conditions." The blanket is a familiar, felt experience the reader already understands, and it is used to introduce the subnivium by comparison — the snowpack does for plants and animals what a blanket does for us.

The analogy is extended later in the passage too, when the author asks us to "imagine being under a stack of blankets that are all flattened and pressed together" to explain why snow density matters. So the blanket image is consistently used as an analogue for the snowpack.

Why C is correct: It names the device — an analogy between blankets and the snowpack.

Why the others fail:

• A — Evoking bitter cold is an incidental side effect of the opening, not the rhetorical job the blanket image is doing.
• B — The author has no interest in explaining how blankets work mechanically; the blanket is a vehicle for comparison, not the subject.
• D — The passage never warns about fatal cold exposure to humans; the life-and-death stakes are discussed for organisms depending on the subnivium, not for people under blankets.

Answer: C

Let's find the one sentence that doesn't belong by first identifying the single unifying idea across the other four.

The common thread

Read sentences 2, 1, 3, and 5 together and notice they all orbit one concept: Federer defying time at Wimbledon.

1. Sentence 2 opens the theme — Wimbledon's "greatest illusion" is the sense of timelessness it creates.
2. Sentence 1 picks up directly on that: "one of its finest champions managed to pull off a similar impression" — i.e., a champion reproduced that very illusion of timelessness. The pronoun "its" links back to Wimbledon; "similar impression" links back to "timelessness."
3. Sentence 3 delivers the proof — Federer, at 35 years and 342 days, became the oldest men's champion, "a full 14 years after he first claimed the title." This is the concrete evidence of time being defied.
4. Sentence 5 explains why he can keep defying time — his method doesn't depend on "explosive athleticism or muscular ball-striking, both vulnerable to decay." It extends the age/timelessness theme into the future.

So the sequence 2 → 1 → 3 → 5 forms a tight, coherent paragraph: Wimbledon evokes timelessness → Federer embodied it → here's the proof → here's why it can last.

Why sentence 4 breaks the unity

Sentence 4 — "Once he had survived the opening week, the second week witnessed the range of a rested Federer's genius" — is a tournament-structure detail. It describes how the fortnight unfolded week by week: surviving the first, peaking in the second. That is about the schedule of play, not about timelessness, age, or defying time.

It doesn't connect to the "illusion of timelessness" idea, and it doesn't extend the age/longevity argument. It sits on a different axis entirely — match progression rather than temporal defiance.

💡 Teacher tip: In Odd-One-Out, once you spot the unifying idea, check whether each sentence advances that idea or merely shares the subject. Sentence 4 shares the subject (Federer at Wimbledon) but advances a different idea (weekly tournament flow), which is exactly what makes it the odd one out.

Answer: 4

Let's build this paragraph link by link, starting with the sentence that can open the discussion.

Finding the opener

Sentence 2 — "The stories we tell reflect the world around us" — is the broadest, most general statement among the five. It introduces the core idea (stories mirror the world) without referring back to anything previously mentioned, so it is the natural starting point.

Building the thread

1. 2 → 5: Sentence 2 claims that stories reflect the world. Sentence 5 takes this one step further: the very moment we try to capture a story, the world we were trying to reflect has already moved on. This is a direct consequence of the opening claim — the world is always changing, so any story is instantly dated.

2. 5 → 3: Because a captured story is never quite current, sentence 3 follows logically: "We cannot help but retell the stories that we value" — they are "never quite right for us — in our time." The phrase "never quite right" picks up the idea from sentence 5 that the world has changed out from under the story.

3. 3 → 4: Sentence 4 extends the phrase "never quite right" with "And even if we manage to get them quite right, they are only right for us" — meaning even a successful retelling is personal; other people will have their own reasons for telling similar stories. The connector "And even if" and the repetition of "quite right" lock sentences 3 and 4 together.

4. 4 → 1: Sentence 1 is the concluding application, signalled by "hence." It draws the general discussion of retelling down to a specific case: retelling Indian stories takes on new meaning in modern India. The word "hence" marks it as a conclusion drawn from everything said before.

Final sequence: 2 → 5 → 3 → 4 → 1

💡 Teacher tip: In para jumbles, look for the sentence that makes a general, self-contained statement as your opener, then follow pronoun echoes and repeated phrases (here: "quite right" linking 3 and 4) to chain sentences together. A concluding sentence often carries a summarising marker like "hence" or "therefore."

Answer: 25341

A primary-purpose question asks you to capture the whole arc of the passage — not just one true fact inside it, but the overarching point the author is making.

Read the opening. The passage begins: "Despite their fierce reputation, Vikings may not have always been the plunderers and pillagers popular culture imagines them to be. In fact, they got their start trading in northern European markets…" That sentence sets the agenda: the author wants to push back against the popular raider image by showing early trade.

Everything that follows is evidence for that agenda:

• reindeer-antler combs found in Danish marketplaces,
• the fact that reindeer don't live in Denmark, implying they arrived by ship from Norway,
• the marketplace setting suggesting trade rather than pillage,
• the dating to the 780s and even 725, which predates the first Viking raids.

So the purpose is to challenge the raider perception using evidence of early trade relations — which is exactly what option C says.

Why the others fail:

💡 Teacher tip: When a passage opens with a contrast phrase like "Despite their fierce reputation…", that contrast is usually the spine of the whole argument — the purpose answer should reflect it.

Answer: C

This is a function-of-evidence question: you are told which detail is used, and asked what point it is used to prove. So don't just ask what the dates mean in isolation — ask what the author does with them in the surrounding sentences.

The line in question is: "Most of the artifacts also date to the 780s, but some are as old as 725." Read the very next sentence: "That predates the beginning of Viking raids on Great Britain by about 70 years."

So the author's move is clear: these are marketplace artefacts, and they date to before the raids began. Together, those two facts show that the Vikings were trading in Europe before they started raiding it. That is exactly option D.

Why the others fail:

💡 Teacher tip: When a question names a specific line, always read the sentence immediately after it — authors usually state the point of their evidence right next to the evidence itself.

Answer: D

An EXCEPT question asks which statement is not supported by the passage. The reliable method: check each option against the text literally, and watch for small swaps — the wrong option usually takes a real idea and changes one key word.

Let's go option by option.

B — supported. The whole point of the dating evidence is that Vikings were trading in Europe before they became raiders: "That predates the beginning of Viking raids on Great Britain by about 70 years." So B holds.

C — supported. The passage states directly: "Antler craftsmanship, in the form of decorative combs, was part of Viking culture. Such combs served as symbols of good health." That matches C.

D — supported. The artefacts were found at marketplace sites in Denmark (including Ribe), and the passage suggests a wider Scandinavian trade network: "It's possible that the antler combs represent a larger trade network, where the Norsemen supplied raw material to craftsmen in Denmark and elsewhere." So D holds.

A — not supported. This is the swap. The passage says the Vikings brought shed reindeer antlers from Norway to Denmark — "the animals shed their antlers also made them easy to collect from the large herds that inhabited Norway" — not live reindeer. Confusing the raw material with the animal itself makes A the false statement.

💡 Teacher tip: In EXCEPT questions, the wrong option often replaces one noun with a related-but-different one. Here, "antlers" becomes "reindeer" — close enough to look right, but not what the passage says.

Answer: A

Let's build this paragraph link by link, starting with the sentence that can open the passage.

Step 1 — Find the opener.

Sentence 4 is the broadest, context-setting sentence: it places us in the 18th century, in a world of global trade and warfare, and tells us that the English reader needed a dictionary. It introduces the situation and the need without referring back to anything, so it must come first.

Step 2 — Who fills that need?

Sentence 4 ends by mentioning "a vigorous and practical champion" who was spreading the language. Sentence 3 then names that champion — "Samuel Johnson was a pioneer who raised common sense to heights of genius." The phrase "vigorous and practical champion" in 4 is picked up by the description of Johnson in 3. So: 4 → 3.

Step 3 — Illustrate the character just described.

Sentence 3 establishes Johnson's defining trait: practical common sense. Sentence 5 gives a famous concrete example of exactly that — he refuted Berkeley's abstract philosophy by simply kicking a stone ("I refute it thus"), and then connects it to his view that "language must have a daily practical use." The anecdote proves the claim made in 3, and the closing phrase of 5 sets up the next idea. So: 3 → 5.

Step 4 — From principle to practice.

Sentence 5 ends with the principle that language must have "a daily practical use." Sentence 1 shows how Johnson applied that principle in his dictionary: he "treated English very practically, as a living language" and based definitions "on the principle of English common law — according to precedent." The word "practically" directly echoes 5, and we move from Johnson's general philosophy to his actual lexicographic method. So: 5 → 1.

Step 5 — The reflective close.

Sentence 2 steps back from the dictionary work to the man behind it: "Johnson found solace in compiling the words of a language that was… the precise analogue of his character." After the paragraph has described who Johnson was (3), how he thought (5), and how he worked (1), sentence 2 reflects on what the work meant to him personally. It is the natural closing note — moving from the work back to the inner life of the man. So: 1 → 2.

Final sequence: 4 → 3 → 5 → 1 → 2

💡 Teacher tip: In a para jumble, watch for the sentence that names a person or thing already referred to vaguely in an earlier sentence — here, 4's "vigorous and practical champion" is resolved by 3's "Samuel Johnson." That resolution is one of the strongest sequencing signals available.

Answer: 43512

What is the paragraph really about?

The paragraph pairs Socrates and Bacon on a shared intellectual habit. The author is not interested in listing everything each thinker did — the focus is on what they have in common when it comes to handling arguments and theories.

Let us trace that common thread:

1. Socrates — his method disproves arguments by finding exceptions, pushing the opponent into a contradiction. So he tests a claim from the negative side.
2. Bacon — he stressed that it is as important to disprove a theory as to prove one, using observation and experimentation for both aims. So he tests a claim from both sides — proof and disproof.

The shared position is therefore: a theory must be examined from both sides — to prove it and to disprove it. That is the single idea the correct summary must capture.

Checking each option

Option A — questioning opponents to disprove arguments. This fits Socrates well (he questioned opponents and found exceptions), but it does not capture Bacon. Bacon's contribution, as the passage states, was observation, experimentation, and the collaborative testing of theories — not "questioning opponents." So A captures only half the picture.

Option B — challenging arguments by observation and experimentation. This is Bacon's side, not Socrates'. The Socratic method works through questioning and finding exceptions, not through real-world observation and experiment. So B captures the other half only.

Option C — confirming arguments by finding exceptions. This reverses the logic. Finding exceptions is used to disprove a claim, not to confirm it. The passage explicitly says the Socratic method "disproves arguments by finding exceptions." So C gets the direction wrong.

Option D — examining arguments and theories from both sides to prove them. This captures the common ground: both thinkers insisted on testing a theory from both sides — proving and disproving. Socrates did the disproving side through exceptions; Bacon explicitly said disproving was as important as proving. D holds the two together without distortion.

💡 Teacher tip: In a paired-thinker summary, the right option must reflect what both figures share — not what belongs to only one of them. Eliminate any option that is true of Socrates alone or Bacon alone.

Answer: D

Let's build this paragraph step by step.

Step 1 — Find the opener

Sentence 5 is the natural opener: "One of the most dramatic examples in nature of ill wind that blows goodness is lightning." It is a self-contained, proverb-style statement that introduces lightning as the subject — nothing in it refers back to an earlier idea. Every other sentence either mentions nitrogen without introducing it, or refers back to something already said. So 5 starts.

Step 2 — Follow the thread link by link

1. 5 → 3: Sentence 5 calls lightning an example of an "ill wind that blows goodness." Sentence 3 immediately tells us what that goodness is: "Lightning starts the series of chemical reactions that need to happen to nitrogen, ultimately helping it nourish our earth." The connection is tight — 5 raises the question, 3 answers it.

2. 3 → 4: Sentence 3 introduces nitrogen as something that needs chemical reactions. Sentence 4 then zooms out to give us background on nitrogen itself: "Nitrogen — an essential food for plants — is an abundant resource, with about 22 million tons of it floating over each square mile of earth." This is the natural "what is this nitrogen?" follow-up.

3. 4 → 2: Sentence 4 tells us nitrogen is abundant in the air ("floating over each square mile"). Sentence 2 states the problem with that aerial nitrogen: "In its aerial form nitrogen is insoluble, unusable and is in need of transformation." The phrase "aerial form" directly picks up on the image of nitrogen "floating" in sentence 4.

4. 2 → 1: Sentence 2 says nitrogen is "in need of transformation." Sentence 1 elaborates on what that transformation means, using an analogy: "Before plants can take life from atmosphere, nitrogen must undergo transformations similar to ones that food undergoes in our digestive machinery." The word "transformations" links straight back to "transformation" in sentence 2, and the sentence brings the paragraph to a close by explaining how plants finally benefit.

Step 3 — Final sequence

5 → 3 → 4 → 2 → 1

💡 Teacher tip: In para jumbles, the opener never contains a back-reference (no "this," "such," "it" pointing to something earlier). Here, only sentence 5 is fully self-contained — every other sentence presupposes an idea already introduced.

Answer: 53421

What is this question asking?

A main-purpose question. You need to capture the whole arc of the passage — every reason the author gives for typewriters still being around — not just one strand of it.

Tracing the passage end to end

The passage opens by admitting typewriters are obsolete — the ink smudges, they're heavy, corrections are a mess. Then it pivots: "But they are also personal, portable and, above all, private." From there the author stacks up the reasons typewriters survive:

• Privacy / security — governments (Russia, the US) use them because a typed, locked document can't be digitally surveilled.
• Nostalgia — the metal body and well-defined keys make them popular on eBay.
• Attentiveness — the machine forces you to prepare, order your thoughts, and focus, with no online distractions.

So the passage is an account of why people continue to use typewriters even in the digital age — covering institutional, nostalgic, and personal reasons.

Why the other options fall short

• B says the passage argues typewriters will continue to be used. But the author describes present reasons for use; there is no forecast or prediction about the future. That shifts the purpose.
• C narrows the passage to personal benefits. That misses the government/institutional use the author explicitly discusses, so it captures only part of the arc.
• D claims the passage shows computers offer fewer options than typewriters — the opposite of the author's stance. The passage says typewriters are simpler and more limited, and that limitation is part of their appeal.

Answer: A

What is this question asking?

A direct retrieval question: what reason does the passage give for governments specifically still using typewriters? Go to the lines that mention Russia and the US.

The key lines

The author says:

"Type a document and lock it away and more or less the only way anyone else can get it is if you give it to them. That is why the Russians have decided to go back to typewriters in some government offices, and why in the US, some departments have never abandoned them."

The logic is about control over access — once a document is typed and locked away, no algorithm or secret surveillance can reach it. The only way someone reads it is if you physically hand it over. That is a security/privacy reason, specific to government use.

Why the other options fail

• A — the passage never says governments keep typewriters because old tech might be useful in the future. That invents a reason not in the text.
• B — this reverses the logic. The author mentions a production line staying in business as a consequence of demand, not as the reason governments use typewriters. Governments aren't keeping the machines alive out of charity.
• C — nostalgia is mentioned in the passage, but it belongs to the eBay buyers, not to government departments. The question asks specifically about governments.

Answer: D

What is this question asking?

An EXCEPT question. Three of the four options describe something the writer praises about typewriters; one does not. Find the option that is either a drawback or something the writer does not commend.

Checking each option against the passage

• A — Unlike computers, they can only be used for typing. The writer treats the machine's single-purpose nature as a virtue: "No online shopping. No urgent emails. No Twitter." That enforced focus is part of the praise for attentiveness. ✔ Praised.

• B — You cannot revise what you have typed on a typewriter. The author turns this irreversibility into a strength: "there's a big premium on hitting the right key," which forces you to sort out ideas and organise details before you start typing. It's a backhanded compliment — the difficulty of revision is framed as enforcing discipline. ✔ Praised.

• C — Typewriters are noisier than computers. The sound is explicitly praised: "The thinking process is accompanied by the encouraging clack of keys, and the ratchet of the carriage return. Ping!" The noise is part of the pleasure. ✔ Praised.

• D — Typewriters are messier to use than computers. This is admitted at the very start as a drawback, not praise: "The ink comes off the ribbon, they weigh a ton, and second thoughts are a disaster." The author concedes these flaws before pivoting to the machine's virtues. ✗ Not praised.

Since D is the one thing the writer does not praise, it is the EXCEPT.

Answer: D

Let's find the one sentence that doesn't belong with the other four.

What unites four of the sentences?

Sentences 1, 3, 4, and 5 all describe the same theme: the specific ways in which we are poor communicators, despite being born with language.

• Sentence 1 sets the stage — research shows we are "surprisingly unskilled when it comes to communicating."
• Sentence 3 gives one symptom — we "choose our words without thought," blind to emotional impact.
• Sentence 4 gives another — we "talk more than we need to," ignoring listeners.
• Sentence 5 gives a third — we "listen poorly" and miss non-verbal cues like facial expressions, gestures, and tone.

Read together, these four sentences form a coherent catalogue of our communication failures — each one adding a concrete example to the claim introduced in Sentence 1.

Why Sentence 2 is the odd one out:

Sentence 2 says: "We must carefully orchestrate our speech if we want to achieve our goals…" This is not a description of how bad we are at communicating — it is advice about what we ought to do. The word "must" signals a prescription, a recommendation. The other four sentences are busy describing the problem; Sentence 2 jumps ahead to prescribing a solution. That shift from describing to advising breaks the paragraph's unity.

💡 Teacher tip: In Odd-One-Out, ask yourself whether each sentence is doing the same job. Here, four sentences are diagnosing a problem; the odd one is prescribing a remedy. Different job = different paragraph.

Answer: Sentence 2

What this question tests: This is a main-idea question. The correct answer must capture the author's central argument — the thesis the whole passage builds toward — not merely a true detail mentioned along the way.

Why C is correct

The passage opens with the news that electric and hybrid vehicles are rising, but it quickly moves past that news to its real claim. The author calls the private car "a device of immense practical help and economic significance, but at the same time a theatre for myths of unattainable self-fulfilment," and later calls the sleek electric car "the most contemporary fantasy of autonomy and power." The closing paragraphs return to this idea: the private car sells a dream of independence that mass ownership actually makes impossible, and the future may dissolve that dream into shared, public-transport-like arrangements. So the author's argument is that the private car represents an unattainable myth of independence — which is exactly what option C states.

Why the others fail

• A is true as a fact in the passage, but it is the news hook the author starts from, not the argument the passage is making. The first sentence signals the end of the internal combustion engine, but the essay's real point is about what the car symbolises.
• B is a supporting detail. The author does praise Musk's abilities, but only as one factor among several explaining Tesla's sales — not as the passage's central claim.
• D makes a speculative comparison the author never draws. The passage discusses both Tesla and Uber-style shared mobility, but it never ranks them by environmental friendliness.

Answer: C

What this question tests: An EXCEPT question. Three of the options are things the author explicitly says about electric cars; one is not. Your job is to find the one the author does not say.

Why D is the answer (the EXCEPT)

The author's point about autonomy being a myth applies to the private car in general — it is a fantasy drivers chase regardless of what powers the engine. The passage does not claim that electric cars specifically erode or undermine driver autonomy. What it does say about electric cars is that they are the latest version of the autonomy fantasy ("the most contemporary fantasy of autonomy and power"), not that they will ultimately destroy that autonomy. So D is the statement the author does not make about electric cars.

Why the others are stated and therefore not the EXCEPT

• A is stated directly: "the rarest materials for batteries would make undeserving despots and their dynasties fantastically rich."
• B is stated: with electric cars, "the air in cities would once more be breathable and their streets as quiet as those of Venice."
• C is implied clearly: the author calls traffic "the inevitable consequence of mass car ownership." Since electric cars are still privately owned cars, swapping the engine does not remove traffic jams — the passage never suggests it would.

Answer: D

What this question tests: You must find the main reason the author gives for Tesla's remarkable sales — the one factor the author explicitly flags as the most important.

Why D is correct

The author lists several factors behind Tesla's sales — Musk's abilities as salesman, engineer, and deal-maker — but then singles out one as decisive: "Mr Musk is selling a dream that the world wants to believe in. This last may be the most important factor in the story." That "dream" is the fantasy of autonomy and power the private car represents, which the author develops in the very next sentences. People buy the Tesla because they buy into that myth of independence. Option D captures this.

Why the others fail

• A claims long-run cost-effectiveness, but the passage never argues that the Tesla saves money over time. In fact, it notes the car has a "fairly short range" and few charging stations — practical drawbacks that make a cost argument implausible.
• B mentions a tax subsidy, which is never raised in the passage.
• C directly contradicts the text: the author stresses the "very limited number of specialised charging stations," not a rapid upscaling of them.

Answer: D

What this question tests: This asks for the author's conclusion — where the argument ultimately lands after all the reasoning.

Why C is correct

The passage dismantles the fantasy of automotive autonomy step by step, then turns to the Uber-style shared-mobility future. The author writes that cars may eventually "work as taxis do, summoned at will but only for the journeys we actually need," and that "the ultimate development of the private car will be to reinvent public transport." So the conclusion is that drivers chase autonomy, but the realistic future points the opposite way — toward public-transport-like arrangements. Option C states this landing point.

Why the others fail

• A is too absolute. The author speaks in terms of possibility ("will become," "will work as taxis do"), not a guaranteed, total end of car ownership. The word "will no longer own" overstates the claim.
• B is a sub-point along the way — the author does mention sensor-equipped cars that avoid collisions — but it is not where the argument concludes.
• D is far too extreme. The author mentions electric bicycles only as an ironic final twist, not as "the only way" to achieve autonomy.

Answer: C

What this question tests: You must identify the purpose the Uber example serves in paragraphs 5 and 6 — what argument is it being used to support?

Why C is correct

The author introduces Uber to illustrate where personal mobility is actually heading. The key sentences are: "the logical outcome of cars which need no driver is that they will become cars which need no owner either. Instead, they will work as taxis do, summoned at will but only for the journeys we actually need," and "the ultimate development of the private car will be to reinvent public transport." Uber is the author's Exhibit A for the private car being transformed, in effect, into a form of public transport. Option C captures this.

Why the others fail

• A describes collision-prevention mechanisms, which the author discusses in an earlier paragraph about sensors and steering — not the point of the Uber example.
• B reverses the author's view. The author says traffic jams will be abolished only when the private car becomes a public utility; the Uber example is not a claim that jams will simply vanish.
• D makes a sales comparison the passage never argues — there is no suggestion that Uber rides will outstrip Tesla sales.

Answer: C

What this question tests: You must explain why the author brings up electrically powered bicycles at the very end of paragraph 6 — what argument does that mention serve?

Why B is correct

The author's final move is ironic. After arguing that the private car is a fantasy of autonomy, and that the realistic future points toward shared, public-transport-like mobility, the author asks: "What then will happen to our fantasies of independence? We'll all have to take to electrically powered bicycles." The point is that if you genuinely want the autonomy drivers dream of — escaping traffic, moving freely — the honest answer may be something as humble as an electric bicycle. Our fantasies of independence may, unexpectedly, point us toward e-bikes rather than ever-more-sophisticated electric cars. Option B captures this irony.

Why the others fail

• A brings in Elon Musk and what he should fund, which the passage never argues. The e-bike mention is not investment advice for Musk.
• C overstates a single ironic observation into a sweeping verdict. The author does not declare that e-bikes rather than e-cars are the future; the line is wry and conditional, not a ranked prediction.
• D introduces electric buses, which are never mentioned. The e-bike reference is about personal autonomy, not about the best form of public transport.

Answer: B

Let's find the one idea that doesn't belong by first identifying what the other four sentences share.

The unifying thread

Sentences 2, 5, 3, and 4 all revolve around hidden meanings embedded in brand logos.

1. Sentence 2 opens with a concrete example — the Commonwealth Bank logo, a recognisable yellow diamond — and notes how iconic it is.
2. Sentence 5 then reveals the secret behind that example: the Southern Cross constellation is tucked inside the diamond. The connector "But" and the phrase "more to it than meets the eye" signal this reveal, flowing directly from 2.
3. Sentence 3 broadens the discussion — "It's not just logos with hidden shapes…" — moving from the CommBank case to the general idea that brands carry vague or lost stories.
4. Sentence 4 explains the why behind this practice: graphic designers embed cryptic references to give the brand a story and make people feel like insiders.

Read as 2 → 5 → 3 → 4, this is a clean paragraph: a specific example, its hidden meaning, a generalisation, and the designer's motive.

Why sentence 1 breaks the unity

Sentence 1 says: "Those geometric symbols and aerodynamic swooshes are more than just skin deep."

The demonstrative "Those" points backward at something already introduced — but no geometric symbols or aerodynamic swooshes appear anywhere in sentences 2–5. The CommBank logo is a diamond, not a swoosh. With no antecedent in the group, sentence 1 references content outside the paragraph and cannot fit.

💡 Teacher tip: When a sentence opens with a demonstrative like "those" or "this", check whether its antecedent exists in the other sentences. If it doesn't, that sentence likely belongs elsewhere.

Answer: 1
