Read each paragraph and choose the option that best captures its essence: the central idea, not a detail or an extension of it.
Question 1 · Multiple choice (+3 / −1)
Cities often treat street trees as decoration, something to be planted when budgets allow and felled when a road needs widening. Yet a mature canopy does measurable work. It lowers surface temperatures on hot afternoons by several degrees, intercepts rainwater that would otherwise overwhelm drains, and filters fine particles from traffic. These services rarely appear on a municipal balance sheet because no one sends an invoice for them. When a tree is removed, the loss shows up elsewhere: in higher electricity bills for cooling, in flood repairs, in hospital admissions during heatwaves. The cost is real but scattered, which is precisely why it is ignored. Valuing trees as infrastructure rather than ornament would change how such decisions are made.
Which option best captures the essence of the paragraph?
Show the solutionSolution
Answer: B. Because the benefits of urban trees are scattered and never billed, cities undervalue them; treating trees as infrastructure would correct this.
The paragraph moves from a mistaken view (trees as decoration) to the reason for it (their benefits are diffuse and unbilled) to a remedy (value them as infrastructure). Option B holds all three.
Option A lists the benefits but turns the argument into advice about planting before heatwaves, which the paragraph never gives.
Option C makes budgets the subject and claims a cause for rising bills; the paragraph is about trees, and the bills are only one place the hidden cost shows up.
Option D introduces a young-versus-mature comparison that the paragraph does not make.
Question 2 · Multiple choice (+3 / −1)
Experience is commonly assumed to produce expertise, but the two part ways more often than we admit. A radiologist who reads thousands of scans improves steadily because each diagnosis is eventually confirmed or contradicted by a biopsy. A stock picker, by contrast, may work for decades without ever learning which calls were skill and which were luck, since markets deliver noisy, delayed verdicts. What separates the two is not talent or effort but the quality of feedback. Where outcomes are quick, clear and attributable, years of practice sharpen judgement. Where they are slow or ambiguous, the same years may only harden confidence. Seniority, then, is a reliable signal of skill only in fields that tell practitioners when they are wrong.
Which option best captures the essence of the paragraph?
Show the solutionSolution
Answer: D. Experience turns into expertise only where practitioners get prompt, clear feedback on their decisions; elsewhere it mainly builds confidence.
The radiologist and the stock picker are examples; the claim they illustrate is that feedback quality decides whether experience yields skill. Option D states exactly that, including the point about confidence.
Option A keeps the examples but gives the wrong reason (rigour of the discipline), whereas the paragraph says the difference is feedback, not the field's standing.
Option B drops the condition: the paragraph says seniority is reliable where feedback is good, not that it should never be used.
Option C turns a remark about markets into a sweeping claim about luck in most professions.
Question 3 · Multiple choice (+3 / −1)
Public discussion of technology dwells on invention: the new drug, the faster chip, the bold infrastructure project. Far less attention goes to maintenance, the unglamorous labour of keeping existing systems working. Yet most of the value people receive from technology comes from things that already exist, such as water mains laid a century ago, power grids and ageing railway signals. Funding follows the excitement, so new projects are launched while old ones decay, and the eventual failures are far costlier than routine upkeep would have been. Engineers who repair rarely win awards; those who build ribbon-cutting showpieces often do. A society that wants reliable infrastructure must learn to reward the people who keep things running, not only those who start them.
Which option best captures the essence of the paragraph?
Show the solutionSolution
Answer: C. Because attention and funding favour invention over upkeep, existing systems decay at great cost; maintenance and those who do it deserve greater reward.
The paragraph contrasts the attention given to invention with the neglect of maintenance, shows the cost of that neglect, and ends by calling for maintenance to be rewarded. Option C covers the cause, the consequence and the conclusion.
Option A is too extreme: the author asks for maintainers to be rewarded 'not only' builders, which does not mean halting innovation.
Option B inflates an example (century-old water mains) into a general claim about imminent collapse.
Option D adds a reason, technical difficulty, that the paragraph never gives, and misses the main point about upkeep.
Question 4 · Multiple choice (+3 / −1)
Archives seem to offer the historian direct access to the past, but they are themselves the product of choices. Clerks decided which letters to file and which to burn; institutions preserved records that justified their own authority; the poor and the illiterate left little paper behind at all. A history written solely from surviving documents therefore risks reproducing the priorities of those who kept them. This does not make archives useless. It means the careful historian must read them for what they omit as well as what they contain, asking whose voices were never recorded and why. The silences in an archive are evidence too, if one learns to interpret them.
Which option best captures the essence of the paragraph?
Show the solutionSolution
Answer: A. Because archives reflect the choices of those who created and kept them, historians must interpret both what they contain and what they leave out.
The paragraph's arc is: archives are shaped by choices, so relying on them alone is risky, so historians should read both their contents and their silences. Option A captures this balance.
Option B contradicts the paragraph, which says outright that archives are not useless; oral testimony is never mentioned.
Option C exaggerates a detail: the paragraph says the poor left little paper behind, not that institutions destroyed their records on purpose.
Option D overstates: the author treats silences as evidence 'too', alongside the contents, not as more important than them.
Question 5 · Multiple choice (+3 / −1)
Open-plan offices were sold as engines of collaboration: remove the walls, the argument went, and colleagues would talk more freely and share ideas. Studies that tracked actual behaviour found the opposite. When workers moved from cubicles into open spaces, face-to-face conversation fell sharply while email and messaging rose. Exposed to constant view and noise, people sought privacy in the only way left to them, by putting on headphones and retreating into screens. The lesson is not that walls are good and openness bad, but that interaction cannot be produced simply by rearranging furniture. People talk when they have reasons to and some control over their surroundings; strip away that control and they withdraw.
Which option best captures the essence of the paragraph?
Show the solutionSolution
Answer: B. Removing walls reduced conversation instead of increasing it, because interaction depends on people's reasons and sense of control rather than on layout alone.
The paragraph reports a reversal (open plans cut conversation) and draws a lesson from it (layout alone cannot create interaction; people need reasons and control). Option B gives both.
Option A treats the rise in email as a benefit; the paragraph presents it as a sign of withdrawal and says nothing about efficiency.
Option C contradicts the author, who explicitly says the lesson is not that walls are good.
Option D shifts the subject to productivity, which the paragraph does not discuss.
Full worked solution
Read the paragraph once for its argument, not its examples. Ask: what is the author trying to make me believe by the last line?
Map the structure in a few words, for example 'common view, why it is wrong, what to do instead'. The right summary usually mirrors that structure.
Eliminate options that pick up a detail or example and treat it as the main point, and options that add a claim, cause or recommendation the paragraph never makes.
Watch the strength of the language. Words such as 'never', 'should stop' or 'most important' often overstate a paragraph that was careful and qualified.
Between two close options, prefer the one that keeps the author's reasoning (the 'because') and not just the conclusion.
