How Sentence Placement Reveals Structure

Two sentences in an RC paragraph can say almost the same thing and be worth completely different amounts. One is the claim the paragraph exists to make. The other restates it with an example attached.

Aspirants who read every sentence at the same weight end up with a passage that is uniformly dense and uniformly forgettable. Aspirants who read positionally know that a paragraph is a small structure, and structures have parts that carry load and parts that fill space.

A colonnade makes this obvious. Five columns, one lintel, and only some of those columns are actually holding anything up. Remove a decorative one and nothing happens. Remove the load-bearing one and the whole thing comes down.

Why Position Predicts Weight in CAT Prose

English paragraphs in serious non-fiction follow a small number of conventional shapes, and those conventions are strong enough to predict from. A paragraph typically raises something, works through it, and lands somewhere, and the landing is what the next paragraph will build on.

That gives position real predictive power. It is not a trick or a shortcut; it is a consequence of how argumentative prose is written, and it holds across the sources CAT draws from.

The practical consequence is that a paragraph divides into two kinds of sentence:

• Load-bearing: the claim, the qualification that limits it, and the transition that connects it forward.
• Filler: examples, restatements, elaborations, and detail that supports without adding.
• Filler is not useless, but it is retrievable. You can find it again in seconds when a question needs it.
• Load-bearing sentences are not retrievable in the same way, because their weight depends on the structure you either built while reading or did not.

The Load-Bearing Sentence: Three Positions That Carry Weight

These are positions rather than content, which is what makes them usable at speed. You can find them before you have fully understood the paragraph.

The paragraph's last sentence is the most reliable of the three, and it runs against how most people read:

• Aspirants read openings hardest and endings fastest, which is exactly backwards for this prose.
• A paragraph that opens with its claim usually spends the rest qualifying it, so the ending still matters most.
• If the last sentence contains a hedge, that hedge is the claim's real shape, not a softening of it.

After a concession is the position that most often decides tone and author's-view questions:

• Concessions grant ground briefly. What follows takes it back and is where the author stands.
• The reversal may be one or two sentences later, so read forward from the concession rather than at it.
• A concession with no reversal anywhere is a sign you have misread it as a concession.

A connector-opening sentence tells you the structure of the whole passage rather than of one paragraph:

• "But" at the start of a paragraph signals the passage has changed direction, not just the sentence.
• "For example" opening a paragraph means the entire paragraph is filler; read it fast.
• "In this respect" or "on this view" attaches the paragraph to a specific earlier claim, and identifying which one is worth two seconds.

What Filler Looks Like, and How Fast to Read It

Being deliberate about what to read quickly is the other half of this, and it is where the time saving comes from.

The last two rows are load-bearing despite being short and easy to skim past, which is what makes them expensive. A qualification changes what a claim asserts, and questions are frequently written around exactly that difference.

How to Mark a Passage Positionally

The marking has to be almost free or it will not survive a timed section:

• One underline per paragraph. The load-bearing sentence, and nothing else.
• Do not underline examples, however striking. You will find them again instantly.
• Bracket qualifications rather than underlining them, so they read as modifiers of the nearby claim.
• Mark connector-opening paragraphs in the margin, since they carry the passage's shape.
• Read your underlines back before the questions. They should form a coherent argument in about fifteen seconds.

Once that habit is in place, most main-idea, purpose and structure questions resolve from the underlines rather than from re-reading, which is where the time comes back.

Common Mistakes in Reading Evenly

Related habits worth dropping:

• Underlining detail. Marking names, figures and examples, which are the most retrievable parts of the passage.
• Skimming qualifications. Passing over "in most cases" and then answering as though the claim were absolute.
• Treating every paragraph as equally important. Example paragraphs exist and can be read at double speed.
• Ignoring the connector. Missing that a paragraph opening with "but" has changed the direction of the whole passage.
• Re-reading to find the argument. Rebuilding at the questions what positional reading would have given you for free.

A Practice Drill for Positional Reading

The drill tests whether load-bearing sentences alone carry the passage, which they usually do.

1. Take fifteen RC passages. For each, underline exactly one sentence per paragraph.
2. Cover the passage and read only your underlines. Write the argument in two sentences from those alone.
3. Now read the questions. Mark how many you could answer from the underlines without uncovering the passage.
4. For the ones you could not, check whether you underlined the wrong sentence or whether the question was genuinely a detail question.

What usually emerges:

• Most main-idea, purpose and tone questions are answerable from underlines alone.
• Detail questions are not, and should not be. They are meant to be looked up.
• Wrong underlines cluster on paragraphs that opened with their claim, which is the less common shape.
• Reading time falls by a noticeable margin once filler is being read at filler speed.

The Bottom Line

A paragraph is a structure, not a block of text. Some of it holds the argument up and some of it is there so the argument does not sound bare. Reading both at the same speed is the most common reason capable readers run out of time in a section they understood perfectly well.

The Load-Bearing Sentence, Recap

• The paragraph's last sentence: where argumentative prose usually lands its claim.
• After a concession: the reversal is the author's real position.
• After a paragraph break with a connector: the sentence carrying the logical join.

Build the Habit on Timed CAT VARC

Uneven reading feels risky until it has saved you time on a real clock. Work through CAT previous year questions in timed blocks, or sit full CAT mock tests and past papers so positional reading holds under fatigue. More reading method sits in the CAT VARC blog archive, and if VARC timing keeps collapsing it is worth having your strategy reviewed honestly.
