Reading Comprehension: Main Point, Inference, Tone and the Structure of a Passage
2. Finding the main point and separating it from support
The main point is the single claim the whole passage exists to make; everything else is support — examples, reasons, qualifications, background. A reliable test is the coverage test: the main point must account for the whole passage, not just one sentence. An option that restates a vivid example, or a detail from one clause, is too narrow; an option that stretches beyond what the passage argues is too broad. The right statement of the main point is usually the one the other sentences are there to serve.
Signal words mark the structure. A contrast word (but, however, yet, although, nevertheless) often precedes the author’s real point, because the author first grants the opposing view and then turns against it. A conclusion word (therefore, thus, so, hence) points to a claim the preceding sentences support. A concession (admittedly, of course, granted) flags a view the author does not finally hold. Read these words as road signs: they tell you where the argument is going before the content does.
3. Inference: what must be true, not what could be
An inference is a statement that the passage forces to be true. The standard is strict: a valid inference leaves no room for the passage to be true while the inference is false. This is why the safest inferences are small. “The author mentions at least one benefit” is nearly always safer than “the author thinks the benefits outweigh the costs,” because the second adds a judgement the passage may never have made. Treat strong verbs — proves, guarantees, always, never, only — with suspicion: a cautious passage rarely entitles a sweeping inference.
A worked case. Passage: “Every trainee who passed the safety audit was allowed on the workshop floor. Priya, a trainee, was not allowed on the floor last week.” What follows? Only that Priya did not pass the audit — that is the contrapositive of the rule and is forced. It does not follow that nobody else failed, or that the audit is the sole requirement for the floor; the passage says passing the audit is enough to be allowed, so being refused means the audit was not passed, but it does not say the audit is the only gate. Reading one conditional in both directions is the classic inference error.
Keep two questions apart. ‘Could this be true?’ is satisfied by anything the passage does not rule out; ‘must this be true?’ is satisfied only by what the passage forces. An inference question always asks the second. If a passage says a shop opens on some weekdays, then ‘the shop opens on Monday’ could be true but need not be, while ‘the shop opens on at least one weekday’ must be true. When two options both seem allowed by the passage, the one you can picture the passage being true alongside its denial is the weaker, and the other is your answer.
4. Tone, attitude and the function of a sentence
Tone is the author’s attitude as revealed by word choice. The common academic tones are measured ones: analytical, cautiously approving, sceptical, critical, neutral. Extreme labels — contemptuous, euphoric, outraged — are rarely right for a careful passage, because the restrained language does not support them. Look at the adjectives and verbs the author chooses: “a promising but untested approach” is cautious optimism, while “a fashionable but hollow approach” is dismissal. The content can be identical; the attitude lives in the modifiers.
A function question asks not what a sentence says but what job it does in the passage: does it introduce a counter-example, concede a point, offer evidence, qualify an earlier claim, or draw the conclusion? Answer it by position and connective, not by paraphrase. A sentence beginning “One might object that …” is raising an objection the author will answer; a sentence beginning “This is why …” is stating a consequence. The right answer names the role; a wrong answer correctly paraphrases the sentence but misstates its role.
- Approving tones run from enthusiastic through appreciative to cautiously positive; critical tones run from sceptical through disapproving to, rarely, scornful. A careful passage usually sits near the middle of these scales, so pick the restrained label over the vehement one.
- Common jobs a single sentence does: to illustrate (give an example), to qualify (set a limit on a claim), to concede (grant an opposing point), to rebut (answer that point), to support (offer evidence) and to conclude (state the upshot). Match the job to the connective sitting in front of the sentence.
5. The structure of a short passage
Short argumentative passages fall into a few recognisable shapes, and naming the shape helps you predict where the answer sits. A claim–evidence passage states a position and then backs it. A problem–solution passage describes a difficulty and proposes a remedy. A two-view passage sets one position against another, usually favouring one. A phenomenon–explanation passage reports a surprising fact or a problem and then accounts for it. Once you see the shape, a question about the author’s purpose nearly answers itself.
| Question type | What it really asks | Winning habit |
|---|---|---|
| Main point | The one claim all sentences serve | Apply the coverage test; reject too-narrow and too-broad |
| Inference | What must be true given the text | Prefer the modest statement; distrust strong verbs |
| Tone / attitude | The author’s stance in the modifiers | Read adjectives and verbs; avoid extreme labels |
| Function | The job a sentence does | Use the connective and position, not the paraphrase |
| Detail | Exactly what one place in the text says | Return to the line; beware the half-right option |
When two options survive your first pass, compare them word by word: the difference between them is exactly what the question turns on. Very often one option is identical to the other except for a single overreaching word — ‘all’ where the passage said ‘many’, ‘causes’ where it said ‘is linked to’, ‘proves’ where it said ‘suggests’ — and that one word decides the question. This is why elimination beats selection: it is usually easier to prove three options wrong, each on a statable ground, than to feel that one is right.
Key takeaways
- The passage is the only authority: choose the option the text supports, not the one that is true in general or sounds sensible.
- The main point passes the coverage test — it accounts for the whole passage; reject options that restate one example (too narrow) or stretch past the argument (too broad).
- A valid inference must be true whenever the passage is true; prefer the modest statement and distrust proves, always, never and only.
- Tone lives in the modifiers; careful passages carry measured tones, so extreme labels are usually wrong. A function question asks a sentence’s job, read from its connective and position.
- Signal words are road signs: contrast words often precede the thesis, conclusion words follow their support, and a conceded view is not the author’s own.
- Wrong options usually fail as out of scope, too strong, half right or reversed; name the fault and the option falls.

Attempt each one before opening the answer. Every explanation names the tempting wrong option as well as the right one, because that is where marks are lost.
Read the passage and answer. “Many towns have begun lighting their streets with sensors that dim the lamps when no one is near. Residents welcome the lower electricity bills. Astronomers add that the dimmer, better-aimed light also makes the night sky visible again.” Which option best states the main point?
Show answer
Answer: A — Sensor-dimmed street lighting brings more than one kind of benefit
The passage lists two distinct gains — lower bills and a visible night sky — so the claim that covers the whole passage is that the lighting brings more than one benefit. Naming astronomers as the biggest gainers compares magnitudes the passage never ranks. Calling star-gazing the main reason towns adopt the lighting asserts a motive the passage never states; it only reports gains. Switching lamps off completely contradicts ‘dim’, which keeps some light.“Every book returned after its due date carries a fine. Rohan returned a library book last week and it carried no fine.” Which statement is best supported?
Show answer
Answer: B — Rohan did not return the book after its due date
A book returned after its due date carries a fine, so a book that carried no fine was not returned after its due date. That does not make it early: handing it back on the due date itself also incurs no fine, so ‘before’ goes beyond what is forced. One book says nothing about what Rohan always does, and nothing is said about other readers.“The new translation is fluent and often graceful, and it will surely win readers. Still, in smoothing the author’s awkward originals it quietly loses the very roughness that gave them their force.” The author’s attitude to the translation is best described as:
Show answer
Answer: C — Admiring of its fluency yet regretful about what that fluency costs
The praise ('fluent', 'graceful') is real, but 'Still' turns to a loss the author minds, so the stance is mixed: admiration with regret. 'Wholly enthusiastic' ignores the reservation after 'Still'. 'Contemptuous' is far too strong for a passage that calls the work graceful. 'Indifferent' is wrong because clear judgements are made on both sides.“Commuters complain that the ring road is always jammed at dawn. The cause is not too many cars but too few exits: three lanes of traffic funnel toward a single off-ramp, and the queue builds behind it.” How is this passage organised?
Show answer
Answer: D — It reports a problem and then identifies its cause
A complaint (the dawn jam) is stated and then explained by a cause (too few exits), which is the problem-then-cause shape. No remedy is proposed, so no solutions are weighed. There is no narrative sequence of events and no definition or history of a term.“Supporters of the open-plan office say it sparks the chance conversations from which ideas grow. That may be so. But the same openness also means a phone call two desks away can end an hour’s concentration, and concentration is where most real work is done.” The sentence “That may be so” functions to:
Show answer
Answer: A — Grant the supporters’ point briefly before raising a weightier objection to it
‘That may be so’ is a concession: the author allows the supporters’ claim just before ‘But’ introduces the stronger counter-point about lost concentration. It is not the conclusion, which comes in the final clause. It offers no statistics, and it withdraws nothing of the author’s own, since the author had made no prior claim to retract.“The museum keeps its most fragile manuscripts in a sealed room where the light is kept very low. Visitors are admitted to that room only in small, timed groups. The curators explain that strong light and crowding both speed the fading of old ink.” Which inference is best supported?
Show answer
Answer: B — The museum’s rules for that room are meant to slow the manuscripts’ fading
Low light and small timed groups directly address the two causes of fading the curators name, so the rules are evidently meant to slow that fading. The one-year destruction claim invents a timescale the passage never gives. Comparison with other museums and visitors’ preferences are both out of scope.“Unlike annual plants, which must be sown afresh each spring, perennials return on their own for several years. But perennials are slow to establish, and most give little show of flower in their first season.” According to the passage, which statement is accurate?
Show answer
Answer: C — Perennials return for several years but most flower little in their first season
The passage says perennials return for several years and that most flower little in the first season — both halves match, with ‘most’ preserved. Returning without resowing is the perennial, not the annual, so that option reverses the pair. The heavy-flowering claim is unsupported: the passage says most perennials make little show in their first season and never compares them with annuals. Slowness to establish is attributed to perennials, not annuals.Read the passage. “The city tested a late-night bus on one route for six months. Ridership was low on weekdays but high on weekends. The city has now kept the service on weekends only.” Which of the following statements are supported by the passage?
Show answer
Answer: A — Weekend ridership on the late-night bus was higher than weekday ridership; B — The service has been kept on the days when ridership during the test was high
The passage says ridership was high on weekends and low on weekdays, so weekend ridership was higher, and keeping the service on weekends only keeps it on the high-ridership days. It gives no reason for dropping the weekday service, so the claim about a shortage of funds is out of scope, and the test ran on ‘one route’, which contradicts the every-route claim.Read the passage. “The report praises the dam for the irrigation it provides, while noting that it displaced two villages and now traps silt that once enriched the fields downstream.” Which of the following does the passage present as drawbacks of the dam?
Show answer
Answer: A — It displaced two villages; B — It traps silt that used to enrich the downstream fields
Displacing two villages and trapping the silt that once enriched the downstream fields are the two harms the passage names. Irrigation is the benefit for which the dam is praised, so it is not a drawback, and the passage says nothing about the river being unsafe to cross, which is out of scope.Read the passage. “Historians once treated the discovery of a letter as the end of an inquiry: the letter said what it said. More recent work treats the letter as the beginning. Who wrote it, for whom, and why it survived when thousands of others did not are all questions that shape what it can be taken to show. A letter that survives because a family prized it may exaggerate that family’s importance; one that survives because it was filed in an archive of complaints will tilt towards grievance. None of this makes letters useless as evidence. It makes careless reading of them indefensible.” Which of the following best states the main point of the passage?
Show answer
Answer: D — Because the survival of a letter is itself shaped by choices, a letter must be read critically, though it remains usable as evidence
The passage argues that how and why a letter survived shapes what it can show, so it must be read critically, yet it expressly keeps letters as evidence. The avoid-letters option contradicts ‘None of this makes letters useless’. The comparison of complaint archives with family collections is a detail the passage never ranks, and the claim that earlier historians ignored letters reverses the passage, which says they treated a found letter as settling the matter.“A chef wrote that a dish is finished not when nothing more can be added, but when nothing more can be taken away without loss. The same, she added, is true of a written paragraph.” With which statement would the chef most likely agree?
Show answer
Answer: A — A paragraph is finished once no part can be removed without losing something
The chef’s test is subtraction: a thing is finished when nothing more can be removed without loss, and she extends it to paragraphs, so she would agree that a paragraph is finished when nothing removable remains. The adding-sentences and the-longer-the-more-complete views are the opposite of her test. Saying they have nothing in common contradicts her explicit comparison.“The guidebook lists the fort’s height, its date, and the number of its gates, and stops there. Of why the fort was built where it was, or what living in it was like, it says not a word.” The author’s tone toward the guidebook is:
Show answer
Answer: B — Mildly critical of how little it explains
‘Stops there’ and ‘not a word’ register a shortcoming the author regrets, so the tone is mildly critical. Gratitude for thoroughness reverses the point, since the author faults the book for leaving things out. It is not neutral, because a judgement is implied. ‘Furious’ is too strong, and the passage mentions omissions, not errors.Read the passage. “No machine in the workshop may run without a trained operator present. During the power cut, no machine ran. The lathe is a machine in the workshop.” Which of the following can be validly concluded from the passage?
Show answer
Answer: A — During the power cut, the lathe did not run; B — The lathe is not permitted to run unless a trained operator is present
No machine ran and the lathe is a machine, so the lathe did not run. The rule that no machine may run without a trained operator present, applied to the lathe, gives the conclusion that the lathe is not permitted to run unless a trained operator is present. The absence of operators is not forced: the machines may have stopped simply for lack of power. Nor is the existence of an operator: the rule requires one for running a machine but never states that one is employed.“The survey found that most respondents who cycled to work did so to save money, and that a smaller group cycled chiefly for exercise. Almost none cited concern for the environment as their main reason.” Which statement is accurate according to the passage?
Show answer
Answer: C — Saving money was the main reason for more cyclists than exercise was
‘Most’ cycled to save money and ‘a smaller group’ for exercise, so money was the main reason for more cyclists than exercise was. The environment was cited by ‘almost none’, so it was not the most common reason. A smaller group did cycle for exercise, so ‘no respondent’ is false. ‘Most’, not ‘everyone’, saved money, so the all-cyclists claim is too strong.“The orchard’s yield fell sharply this year, and the owner blamed the drought. Yet the neighbouring orchard, under the same dry sky, had its best harvest in a decade. The difference, it turned out, was that the neighbour had mulched every tree.” What role does the sentence about the neighbouring orchard play?
Show answer
Answer: D — It supplies a counter-example that casts doubt on the owner’s explanation
The neighbour faced the same drought yet thrived, which is a counter-example undercutting the drought-only explanation — and the next sentence names mulching as the real difference. It does not confirm the drought-only cause; it does the opposite. It is squarely about orchard yield, so not a new topic, and it challenges rather than restates the owner’s claim.“We praise a bridge for carrying heavy traffic, but we judge it most severely by the day it fails. A reputation works the same way: years of steady work can be undone by a single lapse, because trust, unlike weight, is not shared out evenly across the record.” Which best captures the passage’s central idea?
Show answer
Answer: A — A single lapse can outweigh a long record of good work in how a reputation is judged
The bridge is an analogy for the real subject, reputation: a single lapse can outweigh years of good work because trust is not spread evenly. The shared-materials option takes the analogy literally. 'Heavy traffic is the best test' fixes on the bridge detail, not the point. The guarantee option is the opposite of the passage, which says one lapse can undo the record.
