Two sentences may both be correct and yet fail to form a comparison. Consider these statements: ‘Mitosis preserves chromosome number’ and ‘Meiosis is important for reproduction.’ Each offers a useful fact, but the first discusses a numerical outcome while the second discusses a purpose. They do not answer the same question. Good comparative writing puts the two ideas on the same line of enquiry. It shows what is shared, identifies a difference and explains how the supporting evidence permits that judgement. The reader should never have to guess what is being compared.
This is a practice guide for 2027 Singapore–Cambridge Secondary Education Certificate G3 English Language K300. Check the official SEAB G3 syllabus directory and K300 English Language syllabus for the authoritative subject scope. Comparative explanation is a transferable literacy skill, not a separate examination component or a promised question type. It helps you interpret information in comprehension, organise relevant material in writing and judge claims presented through text and other sources. The syllabus tests reading, writing, listening and speaking rather than an imaginary single ‘comparison paper’.
For planning, the 2027 K300 assessment comprises Paper 1 Writing, 1 hour 50 minutes, 70 marks, 35%; Paper 2 Comprehension, 1 hour 50 minutes, 50 marks, 35%; Paper 3 Listening, about 45 minutes, 30 marks, 10%; and Paper 4 Oral Communication, about 20 minutes including preparation time, 30 marks, 20%. Paper 1 includes editing, situational writing and continuous writing; Paper 2 requires careful reading and responding to texts. A useful comparison method travels across those tasks, but answer length, tone and selection of material must still fit the actual instructions. Do not write a mini essay when a question requires a concise response.
This guide comes after Vol 0370 on mitosis and meiosis and Vol 0371 on nth-term patterns. They offer two excellent test grounds. The Biology comparison must align chromosome number with chromosome number, purpose with purpose and genetic relationship with genetic relationship. The Mathematics comparison must align the same stage, unit and domain before judging two plans. We are learning to explain these comparisons in clear English, not replacing the subject teachers’ explanations.
The earlier Vol 0368 on persuasive language and warnings owns the analysis of particular language effects. The Secondary 1 comparative-reading learning guide owns introductory identification of agreement and difference. The present volume is an examination-performance workshop about making an answer defendable when a question offers competing evidence, different times, unequal groups or partly overlapping claims. For a still earlier foundation, PSLE Guide 0077 practises attaching a statement to the correct speaker.
A useful five-step comparison takes less time than a long introduction. First, identify exactly which two items the task names. Second, extract a single common criterion: cost, reason, effect, evidence, period, audience or reliability. Third, write a supported statement about each item on that criterion. Fourth, use a comparative connector that matches the relation: whereas, similarly, however, unlike, more than, less than, or both. Fifth, qualify the conclusion where the evidence covers only a sample, interval, stated condition or author’s opinion. If any stage cannot be completed, an apparently confident answer may conceal a gap.
The difference between comparison and juxtaposition is especially important in oral and continuous writing. Two adjacent paragraphs on two subjects do not automatically compare them. You may describe Plan A in one paragraph and Plan B in another, but the reader still needs to know which point of evaluation unites them. In short comprehension answers, one paired sentence often does the job. In a longer discussion, keep each paragraph organised around a criterion and return to the decision that the task asks the reader to make.
The practice exercises below are original hypothetical questions, not past SEC items or official model answers. Their purpose is to exercise control of evidence, meaning and sentence construction. Write your own response first. Then look at the worked reasoning and ask which constraint made the comparison defensible. The ability to identify that constraint is more valuable than memorising any one example.
Thirty-three original comparison clinics
For each clinic, try a single paired sentence before reading the suggested reasoning. Decide whether you are comparing the same criterion, source group, time and unit. Each clinic contains one deliberately tempting error and a transfer check.
01 — Compare chromosome number with chromosome number
A student’s answer reads: ‘Mitosis maintains the chromosome number, while meiosis makes gametes.’ The biology is partly right but the clauses address different dimensions. This could be a good answer to a broad prompt about function, yet it would not directly answer a request to compare chromosome-number outcomes.
For a matched numerical comparison, write: ‘Mitosis maintains the chromosome number in the daughter cells, whereas meiosis halves the chromosome number in the resulting haploid cells.’ Both halves answer the same criterion. The contrast becomes obvious without an unnecessary introduction.
In a two-mark question, look for two paired distinctions, not four disconnected facts. Underline ‘chromosome number’ in the question and keep both sides inside that boundary. This is also a useful check for essays: each contrasting sentence should remain on one explicit line of reasoning.
02 — Compare function with function
Another student writes: ‘Mitosis is for growth and repair, while meiosis gives cells half as many chromosomes.’ The contrast again shifts categories. The first part is a purpose and the second an outcome, so the apparent balance of the sentence is misleading.
A function-to-function response says: ‘Mitosis supports growth and repair by producing additional body cells, whereas meiosis forms gametes needed for sexual reproduction.’ The sentence uses parallel grammar because the ideas are truly parallel. The reader can evaluate the two roles without rebuilding the comparison.
Use one noun phrase as a private check: ‘The function of each process is…’ If the second half cannot finish that phrase naturally, return to the source material. Parallel form is not merely stylish; it is a test that both claims are answering the same question.
03 — Equal counts can conceal different information
A visitor sees two gametes with four chromosomes and concludes that they must carry identical genetic information. The number four is common to both, but it does not resolve the genetic comparison. Chromosome count and allele combination are different properties.
A careful sentence reads: ‘Although the two gametes have the same haploid chromosome number, they need not have identical genetic information.’ The concession ‘although’ marks a real similarity, while the main clause identifies the limit of what the shared count establishes.
Avoid writing ‘the gametes are different sizes’ unless that property is given. A strong comparison distinguishes what the evidence demonstrates from what it cannot establish. The correction works because it preserves the shared number without overclaiming identity.
04 — Put two costs at the same stage
A club considers P(n) = 3n + 2 and Q(n) = 2n + 12 tiles. A student compares P(5) with Q(10) and announces that Plan P is cheaper. Those numbers describe different stage positions and cannot settle a same-stage question.
At stage five, P uses seventeen tiles and Q uses twenty-two. The supported sentence is: ‘At stage five, Plan P uses five fewer tiles than Plan Q.’ Both quantities have the same stage and the same unit. The wording should not say P is always better.
A comparison becomes invalid when its hidden denominator or reference point changes. Name the common stage and the units explicitly. If the question asks which plan is better for all stages, one example is insufficient; solve the crossing or analyse the rules.
05 — A crossing point changes the verdict
Two models agree at stage ten: P(10) = 32 and Q(10) = 32. A poster uses that equality to say the plans remain identical afterwards. But P adds three tiles per stage and Q adds two, so their later values diverge.
Write: ‘Both plans need 32 tiles at stage ten; however, Plan P grows by three tiles per later stage whereas Plan Q grows by two.’ This compares equality at one stage with differing slopes, rather than turning one match into a universal conclusion.
The phrase ‘at stage ten’ is essential. Without it, the sentence suggests unrestricted equivalence. In English examinations, time, place and condition are often part of meaning, not optional decoration. Check them before removing words to save space.
06 — Compare author claims with author claims
Text A says a garden project ‘could improve students’ enjoyment’. Text B says it ‘has improved enjoyment for the forty pupils surveyed’. A careless response treats both as proof that every student became happier. The texts have different certainty and scope.
An accurate answer is: ‘Text A predicts a possible benefit, whereas Text B reports a positive finding within a defined survey group.’ The first is a possibility claim; the second describes evidence of some kind. Neither by itself proves an effect across the whole school.
Keep author voice separate from your own judgement. You may report that Text B makes a claim without endorsing its methods. When no survey details are supplied, do not invent questions, sample selection or statistics to strengthen a comparison.
07 — The same word can carry different scope
A passage says ‘some pupils preferred the earlier timetable’. Another says ‘most pupils who attended the trial preferred the new timetable’. One may sound contradictory, but different groups and different quantifiers prevent a simple yes-or-no contrast.
Compare the actual populations: ‘The first claim concerns an unspecified group of pupils; the second concerns most of the trial participants.’ The text does not tell us whether the two groups overlap or whether the preferences were measured at the same time.
Underlining ‘some’, ‘most’ and ‘who attended’ often reveals the answer. A strong reader refuses to replace these phrases with ‘all pupils’. The ordinary words are logical boundaries that determine what the writer is entitled to conclude.
08 — An older observation is not a present finding
Text A records that a reading room was full on Monday. Text B reports spare seats on Thursday. A student writes that one article must be false because a room cannot be full and not full. The times are different.
A better comparison is: ‘The Monday observation described a full room, while Thursday’s report recorded available seats; the reports refer to different occasions.’ Nothing in those two facts establishes a contradiction. Conditions may have changed in between.
For event comparisons, write the date or period beside each claim before making a judgement. The time label can turn an apparent inconsistency into a straightforward sequence. Do not invent why the attendance changed unless the texts supply relevant evidence.
09 — Compare rates with rates, not raw totals
School A has 40 pupils absent out of 400; School B has 20 absent out of 100. The raw count is higher at A, but the absence rate is ten per cent at A and twenty per cent at B.
A sentence could say: ‘School A recorded more absent pupils in number, but School B had the higher absence proportion.’ Both statements are true, and the chosen criterion determines which is relevant. If the question asks about proportions, compare ten and twenty per cent.
English reasoning sometimes requires elementary mathematical care. State what the figures measure before turning them into adjectives such as ‘worse’ or ‘higher’. A reader who checks denominators avoids false rhetorical force built from unequal group sizes.
10 — Separate a reported effect from a proposed cause
A school installed a quiet-zone sign and later recorded fewer complaints. One writer says the sign reduced complaints; another says only that complaints fell. The two reports share an observation but differ in causal strength.
Write: ‘Both writers describe a fall in complaints, but only the first attributes the change to the sign.’ The comparison identifies an agreement and the precise point where interpretation diverges. It does not claim the first writer is wrong without testing alternative explanations.
The verb matters. ‘Fell’ describes the observed pattern; ’caused’ offers a mechanism. In a comprehension answer, an extra sentence can note that the evidence presented does not rule out changes in attendance, reporting or other conditions.
11 — A concession is not a reversal
A student writes, ‘Although the new timetable is less convenient, it offers longer revision periods.’ Another interprets ‘although’ as proof that the writer opposes the timetable. The clause actually introduces a disadvantage before presenting a countervailing benefit.
A fair paraphrase says: ‘The writer acknowledges an inconvenience but emphasises an additional revision benefit.’ If a second text opposes the change, compare their overall stances only after establishing which argument each prioritises.
Look for the relationship between clauses. Connectors reveal structure, but they do not always supply an author’s final position by themselves. Use surrounding evidence to decide what the writer ultimately argues.
12 — Distinguish a proposal from approval
A notice says an experiment ‘may begin next term if permission is granted’. A later message says its plan ‘has been approved, but the start date has not been fixed’. Calling both announcements confirmed opening dates loses two separate conditions.
Compare the status: ‘The first notice describes a conditional proposal; the second confirms approval while leaving the start date undecided.’ This line protects the distinction between permission and implementation.
In situational writing, readers may act on your comparison. Do not change ‘approved’ into ‘open now’. Good practical communication makes uncertainties visible before a parent, pupil or visitor relies on the information.
13 — Do not confuse a quote with a writer’s position
A passage quotes an unhappy visitor: ‘The display is too confusing.’ The writer then explains why the revised layout is clearer. A learner reports that the writer thinks the display remains confusing because that phrase is memorable.
A precise comparison says: ‘The visitor criticised the original layout, whereas the writer argues that the revision addresses that problem.’ The two views belong to different speakers and different stages of the display.
Track who owns each statement. Quotation marks are useful evidence, but their presence does not mean the author endorses the quotation. This connects directly to PSLE skills of keeping a speaker attached to the correct reported speech.
14 — Compare evidence types fairly
One campaign uses an anecdote about a pupil who saved time. Another presents average waiting times from a defined trial. A response says the second campaign is more truthful simply because it contains numbers.
A more careful answer is: ‘The first uses an individual experience, while the second offers aggregate trial data.’ The trial may support a broader description, but its reliability still depends on how the measurements were collected and which group they represent.
Avoid making ‘quantitative’ a synonym for ‘conclusive’. The kind of evidence is a relevant comparison criterion; its quality requires further examination. State what the source shows and identify the additional information needed to judge its reach.
15 — Two visuals require shared axes
A bar chart of reading minutes uses a vertical axis beginning at ninety. Another begins at zero. The bars appear to have vastly different gaps even if the underlying numerical changes are similar.
Compare the scales before the visual impression: ‘Both charts report minutes, but their different vertical-axis starting points exaggerate or reduce the apparent size of change.’ The reader needs the labelled values, not only the height of the coloured blocks.
If a question asks which chart better represents the numerical difference, show the figures and explain the display choice. A chart’s design can affect interpretation without changing the values. Do not confuse visual contrast with a larger measured effect.
16 — Strong wording cannot replace missing evidence
Text A says ‘The pilot definitely transformed learning for every participant’. Text B says ‘Some participants reported improved focus’. The first has stronger vocabulary but weaker qualification. A student prefers it for sounding more decisive.
A defensible comparison reads: ‘Text A makes an absolute claim about all participants, whereas Text B limits its conclusion to reports from some participants.’ The sentence compares their evidential reach, not the writer’s enthusiasm.
Words such as ‘definitely’, ‘every’ and ‘reported’ carry important limits. If you need to evaluate reliability, ask what measurements support each assertion. Confident tone does not automatically produce strong evidence, and cautious tone does not automatically mean the finding is unimportant.
17 — Explain effect without inventing feeling
A poster says, ‘One overlooked step could cost a visitor valuable time.’ A second says, ‘Please check the entry requirements before arriving.’ An answer calls the first ‘sad’ without linking that judgement to its words.
A stronger comparison identifies techniques: ‘The first stresses a possible loss to create urgency; the second gives direct procedural advice.’ The claim about effect follows from specific phrasing, even if readers may react differently.
When the question asks for language effect, connect a word choice to a plausible reader response. Avoid claiming that every reader will feel the same emotion. For deeper rhetorical analysis, use the dedicated earlier language-effect owner instead of repeating its whole lesson here.
18 — A comparison needs a clear controlling sentence
An essay gives an entire page on Plan A, followed by an entire page on Plan B. Only the final sentence says that both concern school activities. The essay has description, but almost no direct assessment of their merits.
A useful paragraph opening is: ‘The plans differ most in how they balance initial cost against growth over time.’ Evidence for each plan can then follow in matched order, with a judgement after the comparison.
The controlling sentence gives the reader a reason to hold both sets of facts in mind. Without a criterion, the essay feels like two separate reports. In a short response, this same principle can be achieved with one ‘whereas’ sentence.
19 — Avoid mechanical ‘on the other hand’
A student uses ‘On the other hand’ in every paragraph, including one where the second text agrees with the first. The connector suggests a contrast that the evidence does not support.
For agreement use ‘both’, ‘similarly’ or a direct paired statement. For a genuine difference, use ‘whereas’ or ‘however’. For a limited overlap, ‘both agree that…, but they differ on…’ may be clearest. The relation should select the connector, not the other way round.
During editing, circle every linking phrase and test it against the adjoining claims. Remove connectors that merely make the prose sound formal. Accurate relationships are more valuable than an impressive supply of transitional words.
20 — Parallel wording exposes a false analogy
A student writes, ‘Mitosis is like Plan P because both have more cells.’ The mathematics model P counts exhibit tiles; it does not describe cell division. The analogy moves a property from one system into another without justification.
A defensible cross-subject comparison says: ‘Both Biology and Mathematics require us to define what is counted, but the Biology model concerns chromosome number and the tile pattern concerns objects in an exhibit.’ It notes a transferable reasoning skill without equating the processes.
When using an analogy, name both its useful similarity and its boundary. The learning value lies in the habit of checking quantity, not in pretending an nth-term tile rule is a law of genetic reproduction.
21 — Keep the unit attached to an adjective
One report states a five-minute reduction in waiting time; another reports a five-per-cent reduction. A student calls them equal improvements because each includes the number five.
They use different units and may have different baselines. To compare their effects, we need the starting times or an agreed common measure. The clear response is: ‘The first reports an absolute time change, while the second reports a proportional change.’
The difference between five minutes and five per cent is not a technical footnote. It determines the information that can be inferred. If a passage withholds the baseline, say the claims cannot yet be ranked by size on the supplied figures.
22 — Evidence from one class is not a school average
A study room report surveys one Secondary 3 class. A news paragraph rewrites its positive findings as ‘students across the school were more productive’. The second has silently widened the population.
Compare scope explicitly: ‘The survey describes responses from a single class, whereas the summary presents them as school-wide.’ That change is a generalisation not justified by the information supplied.
In your own writing, identify sample size and selection when relevant. If those details are missing, keep the claim narrow. A precise sentence can be shorter and more trustworthy than an ambitious headline that outruns the data.
23 — Contrast outcomes without attributing motives
Text A recommends a quieter corridor; Text B recommends more seating. An answer says the second writer is selfish and dislikes silence. Neither motive appears in the information.
A sound comparison names the proposed solutions: ‘The first writer prioritises noise reduction, while the second prioritises capacity.’ The priorities can be compared on consequences if the passages provide evidence, but personality claims require separate support.
Do not turn disagreement over policy into an invented character judgement. In a comprehension answer, a writer’s stance is supported by stated reasons and tone, not by assumptions about moral qualities or private intentions.
24 — Distinguish data from interpretation
A chart shows sixteen pupils chose Option A and fourteen chose Option B. A writer calls Option A the overwhelming favourite. The underlying difference is only two pupils in the measured group.
A careful response reads: ‘Option A received two more choices than Option B; the description overwhelming exaggerates that narrow margin.’ This directly links a language judgement to the values that test it.
If percentages are requested, calculate them using the correct total and note whether there were other options. Do not manufacture a majority by considering only two options if the complete sample includes a third. Context and denominator control the verdict.
25 — A condition can reverse the preference
Plan A is cheaper for fewer than ten stages; Plan B becomes cheaper after ten. An essay says one plan is always economical because it starts with fewer tiles. The claim ignores the crossing point.
A useful comparison says: ‘Plan A has the lower count at early stages, but Plan B uses fewer tiles beyond their equality stage.’ Insert the exact stage range only after calculating it. The judgement changes with the task’s time horizon.
Good prose does not conceal changing conditions. Instead of a blanket ranking, describe where each option is stronger. That is the kind of balanced decision a practical situational-writing task may need.
26 — Handle numerical precision in a sentence
One estimate is rounded to 20 metres, while another measurement is recorded as 19.6 metres. A student says the first is certainly larger. Rounding can hide a range of possible original values.
A more careful response is: ‘The rounded estimate and the recorded measurement cannot be compared as exact values without considering the precision of the first.’ This states why the conclusion is uncertain rather than avoiding the comparison.
If a question gives a rounding rule, use it. If it does not, do not invent a precise original value. English claims about ‘higher’ and ‘lower’ should respect the accuracy of the underlying evidence.
27 — Keep the proposed action separate from the observed problem
A survey finds that visitors are confused by signs. A committee recommends moving the signs. A student writes that relocating the signs already improved navigation because the proposal followed the survey.
The observation is confusion; the proposed action is relocation; improvement is an outcome that would need later measurement. A comparative statement can say: ‘The survey documents the difficulty, while the committee paper proposes a possible remedy.’
This distinction is especially important in public-facing messages. Readers may mistake a plan for an implemented change. Use words such as ‘proposed’, ‘under trial’, ‘approved’ and ‘completed’ accurately, and anchor each in the source.
28 — Avoid comparing a fact with a question
Text A says the school received 100 visitors on Friday. Text B asks whether Saturday’s opening hours should change. The second is not a rival numerical claim and cannot directly disprove the first.
Compare their functions instead: ‘Text A reports attendance, whereas Text B raises a decision for consideration.’ It is perfectly valid to compare reporting purpose with decision-making purpose if the task asks for textual function.
A source may contain a proposal, question, prediction, observation or conclusion. Identify its speech act before placing it against another source. Two texts about the same place do not necessarily make comparable factual claims.
29 — Find the strongest shared claim first
A science-club flyer says both plans can host an exhibition. One plan uses fewer tiles at stage five; another offers a wider walkway. A student claims that both plans have identical costs because they share a purpose.
A balanced comparison begins with the actual agreement: ‘Both plans would support the exhibition.’ It then distinguishes separate criteria: the number of tiles and the available walkway space. Neither shared purpose nor one cost figure resolves the overall decision alone.
Writing ‘both’ is useful only when followed by a property that both genuinely share. Similar labels, such as ‘exhibition plan’, do not prove similar measurements or outcomes. Ask which criterion the question really needs.
30 — A quote needs its immediate context
A visitor says ‘I prefer the old version’ and immediately adds ‘but only if the new entrance remains closed’. Quoting only the first half suggests unconditional opposition to change.
A precise comparison retains the qualification: ‘The visitor prefers the old version under the stated entrance condition, rather than rejecting the new version without reservation.’ The change in meaning is caused by omission, not by an obscure vocabulary word.
For short quotations, read the sentence before and after the selected phrase. Conditions, negations and exceptions often sit next to a memorable opinion. Do not trim away the material that limits the claim.
31 — Make the final judgement responsive
An essay concludes, ‘Both choices have pros and cons.’ It is safe but unhelpful when the task specifically asks which plan the committee should use for a one-day display at stage five.
A better ending identifies the criterion and makes a conditional choice: ‘For the stage-five display, Plan P needs fewer tiles than Plan Q, so it is the simpler choice on tile count alone. The committee should still verify space and accessibility.’
A conclusion is not required to sound absolute. It should answer the question to the extent that the evidence permits. State the basis of your recommendation and name any unresolved factor that could change it.
32 — Distinguish summary from a comparison essay
A comprehension summary asks for relevant points in about eighty words. A learner spends most of the allowance comparing the personalities of two writers, even though the task asks about conditions of a trial.
A summary selects and compresses the requested information; an extended comparative essay may evaluate positions, structure and consequences. The same reading skills support both, but their outputs differ. Choose facts that match the stated summary focus instead of writing an unrelated debate.
Before composing, draw a box around the task words. Paraphrase only where meaning remains stable. Do not add personal judgements or external knowledge to an answer that requests information from the text.
33 — A complete three-source comparison
Text A says a proposed exhibition will add educational value. Text B lists 5, 8, 11 and 14 tiles in its first four stages. Text C warns that tile counts are not counts of living cells. A student merges the three into ‘the school proved cell growth increases by three’.
A strong response gives each source its role: A proposes a benefit, B documents a linear design pattern and C states the limit of that analogy. The common subject is the exhibition, not an established biological growth rate. The evidence does not support the merged claim.
The final task is to write an honest visitor explanation in two sentences. Try: ‘The exhibit adds three display tiles at each stage. This is a design pattern, not a measurement of the number of cells produced during mitosis.’ Check that each statement has a rightful source.
Turn worked comparisons into a repeatable method
On a blank page, draw a table with two source columns and one row for each criterion. In the first row write what each source says about the same outcome. In the next, record their evidence. In the third, record qualifiers, including sample, period and condition. Only then draft a sentence that compares one row at a time. This simple structure works when you have two articles, two plans, two speakers or two kinds of scientific process. It also exposes a missing comparison: if one column contains an observation and the other contains a recommendation, choose a new common criterion or explain that the claims cannot be directly ranked.
Practise writing one concise sentence before attempting a paragraph. A useful pattern is ‘Both [sources] agree that [shared claim], but [A] limits its claim to [specific scope] whereas [B] extends it to [different scope].’ Use the pattern only when it matches the source. If no shared proposition exists, do not manufacture one for the sake of symmetry. Sometimes the fairest answer is that the passages discuss different aspects of the problem. The purpose of the structure is to sharpen judgement, not to replace it with a template.
For longer writing, build a paragraph around one criterion rather than one source. Begin by explaining what you are comparing, present only the evidence that bears on that feature, explain the relationship and end with what it means for the task. Your next paragraph may use a different criterion, such as cost, access or certainty. Paragraph division should guide the reader through the decision, not give each source a separate isolated room. Keep tone proportionate to the audience and instructions.
An independent ten-minute rehearsal
Read this fictional situation. A school science club has two ways to build a learning display. Plan P requires 3n + 2 tiles at stage n; Plan Q requires 2n + 12 tiles at stage n. At stage five, a teacher measures the intended layout, not a biological specimen. The display also explains that normal mitosis maintains chromosome number, whereas normal meiosis reduces it for gamete formation. A visitor notices that the stage counts rise and concludes that chromosomes must increase by three during mitosis.
Write a four-sentence response. In the first, state what the two plans have in common. In the second, compare their tile counts at the same stage: seventeen for P and twenty-two for Q at stage five. In the third, explain why that display pattern cannot serve as evidence of chromosome behaviour. In the fourth, compare mitosis and meiosis on one matched biological criterion. Then revise your response so that each sentence has a clear subject, the correct quantity and no unsupported universal claim. Do not turn your answer into a laboratory report or claim that the fictional trial actually occurred.
The most important self-check is to read only the nouns after the comparative words. ‘Cost versus cost’ is coherent; ‘cost versus purpose’ needs explanation. ‘Reported result versus reported result’ is coherent when populations and times match. ‘One group’s result versus the entire school’s wellbeing’ is unsafe without a supported inference. This noun-level check is surprisingly powerful under examination pressure. When you find a mismatch, do not merely replace the connector; repair the comparison itself.
