CAT (Common Admission Test) · Verbal Ability & Reading Comprehension
RC Structure and Tone
What a paragraph or sentence is doing in a CAT passage, and how the author stands toward the subject — function and tone, not grammar and not a main-idea recap.
A CAT structure question is not asking you to retell a paragraph. It is asking what that paragraph is doing in the passage — planting a popular view, conceding a cost, pivoting to a sharper question — and, on tone stems, how the author stands toward the subject. The same sentence can be true as content and wrong as a function answer. Main idea and must-be-true inference live on their own topics; the work here is role and attitude. One running passage carries every card: critics call recommendation systems filters; the author finds that metaphor politically useful but descriptively incomplete, because recommenders also surface titles nobody searched; the close grants the industry's remaining harm and asks who writes the ranking objective.

1Function names the job, not the content
A function stem — "serves primarily to", "in order to", "the function of the third paragraph" — wants the job a stretch does for the surrounding argument. A correct option uses a role verb: plant a view, qualify it, illustrate, concede, pivot. An option that retells the stretch accurately but never says why the author placed it there fails the stem even when every fact in it is true.
In the recommendation-metaphor passage, paragraph 2 says recommenders surface a 1970s documentary beside a new thriller. That is content. The job of those titles is to show that a filter, which only subtracts, is an incomplete description. The same sentence can be true as content and wrong as a function answer.
Figure. Paragraph 2's 1970s documentary beside a new thriller is content. Its job is to show a recommender adding an unexpected title, so filter cannot be a complete description.
Role first
- Mark the stemCircle serves primarily to / in order to / function so you stay on role, not paraphrase.
- Name the jobIn one plain verb, say what the stretch does for the passage: plant, qualify, illustrate, concede, pivot.
- Drop restatementsReject any option that only retells the stretch's facts and never names its job.
Answer the function stem, not the content
Recommendation-systems passage. The author observes that recommenders also surface titles the reader would never have searched for. A stem asks what that observation is doing in the argument, not what it says. (A) reports that recommenders can suggest unsearched titles; (B) supplies a counter-case so the 'filter' metaphor cannot be a complete description; (C) argues that users should write the ranking objective themselves; (D) concedes the industry's remaining harm.
- A, recommenders suggest unsearched titlesretells the observation and names no job, reject as paraphrase
- C, users should write the objectivethat is the closing pivot, not this observation, reject as the wrong stretch
- D, concede remaining harmalso part of the close, a different move, reject as the wrong stretch
- B, makes 'filter' incompletenames the job: it is why the metaphor is only partly right, keep
Pro tip. A function answer uses a role verb (illustrate, qualify, concede); a faithful retelling of the sentence that never says why it is there fails a function stem.
Recommendation-metaphor passage, paragraph 2: "Many recommenders also surface titles the user would never have queried: a 1970s documentary beside a new thriller." A stem asks what that sentence serves primarily to do. Which option answers the function stem?
- It reports that a documentary can appear next to a thriller
- It supplies a case in which a recommender adds an unexpected title, so "filter" cannot be a complete description
- It argues that users should write every ranking objective
- It praises critics for naming narrowing as a harm
A function answer names the job: a counter-picture that makes "filter" incomplete. Reporting the documentary/thriller pair retells content and never says why the pair is there. Users writing the objective is the close of paragraph 3, not this sentence. Praising critics is the grant in paragraph 1, not the job of paragraph 2.
2Name each stretch in one job verb
Once you are looking for a job rather than a paraphrase, you need a short list of jobs CAT actually keys. A paragraph is not "the introduction" or "the body" as a school essay uses those words. It is doing one of a few argumentative things: planting a view the author will handle, stating the author's own claim, giving a case, parking an objection, or turning the argument.
The recommendation-metaphor passage is three jobs, not three topics. Paragraph 1 plants the filter slogan and grants why the slogan is attractive. Paragraph 2 qualifies that slogan with a curatorial counter-picture. Paragraph 3 parks the remaining harm ("None of this rehabilitates the industry") and pivots to who writes the ranking objective.
Recommendation-metaphor passage as three jobs, not three boxes: paragraph 1 plants the filter slogan and grants why it attracts; paragraph 2 qualifies the slogan with titles nobody searched; paragraph 3 concedes remaining harm and pivots to who writes the ranking objective.
One verb each
- Ignore the school labelsDo not tag a paragraph intro / body / conclusion. Those names describe position, not job.
- Pick from the job listMatch the stretch to plant, claim, illustrate, concede, or pivot — the Paragraph jobs table.
- Check the next sentenceA job is confirmed by what the author does with the stretch, not by where it sits.
Name the job from what the sentences do, not from the paragraph's place in the page.
| Job | What the stretch does | Cue in the prose |
|---|---|---|
| Plant a view | Puts someone else's claim on the table to be handled | critics have described; it is often said |
| Claim | States the author's own point | it is also incomplete; the useful question is |
| Illustrate | Gives a case that makes a prior claim concrete | a documentary beside a thriller |
| Concede | Parks an objection so the author can return | none of this; granted; to be sure |
| Pivot | Turns the argument to a sharper question or claim | the useful question is therefore |
Recommendation-metaphor passage, paragraph 3 opens "None of this rehabilitates the industry" and closes "the useful question is therefore not whether an algorithm hides, but who writes the objective." Which pair names the paragraph's jobs?
- Plant a view, then illustrate it with a cookbook
- Concede remaining harm, then pivot to who writes the objective
- Define filter, then define curator
- Narrate the history of recommendation systems, then stop
"None of this rehabilitates" parks the political worry; "the useful question is therefore" turns the argument. The cookbook/documentary pair lives in paragraph 2, so "plant then illustrate" names the wrong stretch. The paragraph defines neither filter nor curator. It is not a history and it does not stop after a timeline.
3A local job is not the passage's purpose
A sentence can do a real job in its paragraph and still be the wrong answer to a whole-passage purpose stem — and the reverse is also a trap. Structure items often ask about one stretch. The attractive wrong option promotes that stretch's local job into a claim about why the whole passage was written.
"The metaphor is politically useful" is doing local work in paragraph 1: it grants why the filter slogan stuck. It is not the author's reason for writing. The passage exists to replace a slogan with a sharper question, not to celebrate the slogan's politics. Promoting a local grant to a global purpose is how a true sentence becomes a false function answer.
Figure. The filter metaphor is politically useful grants why the slogan stuck, inside paragraph 1. Promoting that grant to the reason the whole recommendation-metaphor passage was written turns a local job into a false purpose.
Keep the job local
- Read the stem's scopeDoes it ask about this sentence, this paragraph, or the passage as a whole?
- Name only that scope's jobA grant inside paragraph 1 stays a grant. Do not promote it to "the author wrote this to praise the slogan."
- Check the other paragraphsIf later stretches qualify or replace the local point, the local point cannot be the global purpose.
Recommendation-metaphor passage. Stem: "The author mentions that the filter metaphor is politically useful primarily in order to…" Which option stays inside that sentence's local job?
- Argue that recommendation systems are, on balance, a public good
- Grant why a slogan the author will later call incomplete still has force
- Prove that every ranking objective is written by the user
- Summarise the passage's closing question about who writes the objective
The sentence grants why the slogan stuck, immediately before the author calls the description incomplete. "Public good" invents a defence the passage never makes. Users writing every objective is false even as content. The closing question is paragraph 3's job, not the job of the "politically useful" grant.
4A concession parks an objection; it is not the view
Authors often give the other side a sentence so they can keep writing. Cues such as "none of this", "granted", "to be sure", and "this is not to deny" park an objection. The next sentence usually returns to the author's own claim. A function option that treats the parked sentence as the author's new belief has misread the concession.
"None of this rehabilitates the industry" does not mean the author has abandoned the curatorial description, and it does not mean the author now speaks for the platforms. It keeps the political worry on the table so the pivot — who writes the objective — does not sound like a free pass.
Figure. 'None of this rehabilitates the industry' parks the remaining harm so the pivot — who writes the objective — does not sound like a free pass. It does not announce that the author now defends platforms.
Park, then return
- Mark the cueCircle none of this / granted / to be sure / this is not to deny.
- Read the next sentenceThe return — "the useful question is therefore" — is the author's continuing claim.
- Refuse the flipDo not key an option that says the author has switched sides or withdrawn the prior claim.
Recommendation-metaphor passage, paragraph 3: "None of this rehabilitates the industry. Curation can still flatten taste… The useful question is therefore not whether an algorithm hides, but who writes the objective." What does the opening sentence serve primarily to do?
- Announce that the author now defends recommendation platforms
- Withdraw the claim that recommenders can surface unexpected titles
- Park the remaining harm so the next sentences can pivot without sounding like a free pass
- Define ranking objective as a technical term for new readers
The sentence parks the harm; the "therefore" sentence is the return. Defending platforms flips the concession into a new belief. Withdrawing the documentary/thriller claim invents a retraction paragraph 2 never makes. The sentence defines no term.
5Tone is attitude toward the subject, not the topic name
Tone is how the author stands toward the thing under discussion — skeptical, wary, corrective, dryly amused — not a label for the topic ("about algorithms", "about critics"). A tone option has to match two things: polarity (for, against, or mixed) and strength (mild versus sweeping). A savage denunciation fails a passage whose verbs are "incomplete" and "useful question". An enthusiastic endorsement fails a passage that refuses to rehabilitate the industry.
Toward the filter metaphor, the recommendation-metaphor author is skeptical: the slogan is granted as politically useful and then called descriptively incomplete. Toward the industry, the author is unsentimental — "none of this rehabilitates" — without becoming a rant. Toward curation as a description, the author is willing, then immediately limits it. One passage, three attitudes; the stem must say which object you are matching.
Object, then charge
- Name the objectAttitude toward what — the slogan, the industry, or the curatorial description? The stem names the object.
- Read the author's verbsUseful, incomplete, none of this rehabilitates, the useful question is — those words set polarity and strength.
- Match bothDrop the option that flips polarity, and drop the option that keeps polarity but overshoots strength.
The object in the stem is the thing whose charge you match. A right polarity with the wrong strength is still wrong.
| Object in the stem | Author's charge | Option that fails |
|---|---|---|
| The filter metaphor | Skeptical: useful politics, incomplete description | Enthusiastic endorsement, or contempt for anyone who uses the slogan |
| The industry | Unsentimental: remaining harm is real | Cheerleading for platforms, or a denunciation the prose never reaches |
| Curation as a description | Willing, then limited | Treats curation as a full defence of ranking |
Match tone by object, polarity and strength
Recommendation-systems passage. Stem: the author's attitude toward the 'filter' metaphor. The author calls it politically useful but descriptively incomplete. (A) enthusiastic endorsement of the metaphor; (B) contemptuous dismissal of anyone who calls recommenders filters; (C) neutral textbook definition; (D) qualified: useful in politics, incomplete as description.
- A, enthusiastic endorsementkeeps 'useful' and drops 'incomplete', one-sided, reject
- B, contemptuous dismissalright that it is criticised but overshoots strength; the author still grants a use, wrong strength
- C, neutral definition'useful but incomplete' carries a stance, so not neutral, reject
- D, qualified and mixedmatches 'politically useful' plus 'descriptively incomplete', keep
Pro tip. A tone option must match the object the stem names, then both polarity and strength; a right polarity at the wrong strength, such as contempt for measured criticism, still fails.
Recommendation-metaphor passage. Stem: "The author's attitude toward the filter metaphor is best described as…"
- Enthusiastic endorsement of a slogan that finally names the harm
- Contemptuous dismissal of anyone who still uses the word filter
- Skeptical: the slogan is granted as politically useful and then treated as descriptively incomplete
- Neutral textbook definition with no stance toward the slogan
"Politically useful" plus "incomplete" is mixed-to-skeptical, not a cheer and not a sneer. Endorsement keeps only the grant. Contempt overshoots strength: the author still grants the slogan a political use. Neutral fails because the verbs carry a stance.
6A cited view is not the author's claim
CAT passages often open by handing you someone else's sentence. "Critics have described", "it is often said", "one common view holds" plant a view the author is about to handle. The planted view can be quoted, paraphrased, or even granted a virtue. It is still not the author's claim until the author takes it up in their own voice.
"Critics have described recommendation systems as filters" is a cited metaphor. The author's own first move is to grant the metaphor a political use and then deny that it is a complete description. A function option that says the author "argues that recommenders are filters" has assigned the critics' verb to the wrong speaker.
Figure. 'Critics have described recommendation systems as filters' plants a cited metaphor. The author's own move grants it a political use and then calls it incomplete. Assigning 'are filters' to the author mixes speakers.
Who is speaking
- Mark the attributionCircle critics have described / it is often said / one view holds — those name another speaker.
- Find the author's verbLook for the first sentence that is not attributed: here, "It is also… incomplete" and "the useful question is".
- Keep the voices apartA function answer may say the opening plants a view. It may not say the author asserts that view.
Recommendation-metaphor passage, paragraph 1: "For two decades, critics have described recommendation systems as filters: machines that hide most of a catalogue…" What does that opening serve primarily to do?
- State the author's thesis that recommenders are filters
- Plant a common metaphor the author will grant a political use and then call incomplete
- Prove, with the documentary example, that hiding never occurs
- Announce that ranking objectives should be written by critics
"Critics have described" attributes the filter claim; the author's later verbs handle it. Calling it the author's thesis assigns the critics' verb to the wrong speaker. The documentary example is in paragraph 2 and does not prove hiding never occurs. Critics writing objectives is not in the passage.
Notes
- Function names the job, not the content: A "serves primarily to" stem wants the work a stretch does for the argument - plant a view, qualify it, illustrate, concede, pivot. An option can restate the stretch accurately and still fail, because it never says why the author placed it there.
- Argumentative job, not the school-essay slot: Intro, body and conclusion name position. CAT keys what the paragraph does: planting a view the author will handle, stating the author’s own claim, giving a case, parking an objection, or turning the argument.
- A local job is not the passage’s purpose: A grant inside the opening paragraph stays a grant. Promoting a true local move into the reason the whole passage was written is how a true sentence becomes a wrong function answer.
- A concession parks an objection: Cues such as "none of this", "granted" and "to be sure" keep the other side on the table so the author can carry on. The next sentence is the return, not a change of sides.
- Tone is polarity and strength toward a named object: The stem names the object whose charge you have to match, and the author’s own verbs fix both polarity and strength - "incomplete" is scepticism, not contempt. One passage can hold different attitudes to a slogan, to an industry and to a rival description.
- A cited view is not the author’s claim: "Critics have described", "it is often said" and "one view holds" name another speaker. The view stays theirs until the author takes it up in an unattributed sentence.
Formulas
- Function stems ask for the job a stretch does — plant a view, qualify it, illustrate, concede, pivot — not for what the stretch says.
- Use argumentative slots, not essay slots: planting a view the author will handle, stating the author's claim, giving a case, parking an objection, turning the argument.
- Locality rule: a grant inside the opening paragraph stays a grant; promoting a true local move into the passage's purpose is the standard wrong answer.
- Concession cues — "granted", "to be sure", "none of this" — keep the other side on the table; the next sentence is the return, not a change of side.
- Tone is polarity plus strength toward the object the stem names, fixed by the author's own verbs: "incomplete" is scepticism, not contempt.
- Attribution cues — "critics have described", "it is often said", "one view holds" — keep a claim with its speaker until the author states it unattributed.
Exam traps & shortcuts
- A function option can restate the stretch perfectly and still be wrong because it never says why the author put it there.
- Intro / body / conclusion labels are position, not job. An option phrased that way is usually the throwaway.
- After a concession cue the argument returns; readers who take the concession as a change of side mis-tag the whole paragraph.
- Tone stems name their object — the author can be warm about a finding and cold about the slogan built on it in the same passage.
- Attributed views stay with the speaker. Handing "critics have described" to the author is the single most common structure error.
Reference tables
On a function stem, predict one of these jobs before you open the options. A restatement of content is not on this list.
| Job | What you should be able to say | Typical cue |
|---|---|---|
| Plant a view | Someone else's claim is on the table to be handled | critics have described; it is often said |
| Grant / concede | An objection is parked; the next sentence usually returns | none of this; granted; to be sure |
| Qualify / challenge | A prior description is incomplete or wrong in part | it is also incomplete; that is not the whole |
| Illustrate | A case makes the prior claim concrete | for example; a documentary beside a thriller |
| Pivot | The argument turns to a sharper question | the useful question is therefore |
Match the object named in the stem, then match both the sign of the charge and how hard the author presses it.
| Check | What you match | How the option fails |
|---|---|---|
| Object | Slogan, industry, method — whichever the stem names | Right charge, wrong object |
| Polarity | For, against, or mixed, from the author's own verbs | Cheer where the prose is wary, or the reverse |
| Strength | Mild skepticism versus sweeping attack | Contempt or denunciation where the verbs are incomplete / useful question |
| Voice | Author versus cited critic | Assigns a planted view to the author |
Recap
Read only this the night before a VARC set.
- Function
- Name the job — plant, qualify, illustrate, concede, pivot — not a paraphrase of the stretch.
- School labels
- Intro / body / conclusion name position. CAT keys the argumentative job, not the school-essay slot.
- Local ≠ global
- A true local grant ("politically useful") is not why the whole passage was written.
- Concession
- None of this / granted parks an objection. The next sentence is the return, not a change of sides.
- Tone
- Match the object in the stem, then polarity and strength. Incomplete is not contempt.
- Voice
- Critics have described is a planted view. It is not the author's claim until the author takes it up.
