Identifying a Clear Central Claim

A central claim is the one sentence every other sentence in a passage exists to support. Find it by asking which sentence needs the others, not which sentence sounds the loudest.

An argument is built like a structure: one claim on top, and reasons and evidence underneath holding it up. There can be several true, forceful, or interesting sentences in a passage, but only one of them is what all the others are working for. That's why a passage can run for a hundred words and still have exactly one load-bearing claim - everything else is a beam, a brace, or a number brought in to prove the beam is solid. To find it, don't ask which sentence hits hardest. Ask which sentence the other sentences would be pointless without.

This is where the test plants its trap. A vivid or blunt line - 'the fee is a wall, plain and simple' - grabs attention, but check what it's doing: is it the point, or is it a prop making the point land? In the museum example, the fee-as-wall line and the attendance statistic both serve one sentence: that dropping the fee is the museum's most important reform. Strip away the claim and those other lines have nothing to attach to; strip away a supporting line and the claim still stands, just less convincingly.

This sits right next to counterclaims and sufficiency because finding the claim is step one of judging whether the argument holds. A counterclaim is something the passage raises and answers or sets aside, not the thing it's arguing for. And once you've isolated the real claim, you can ask whether the evidence underneath is actually enough to support it - which is the next question the test asks after this one.

Key terms

central claim
The one sentence an entire passage is organized to support, which every other sentence exists to back up.
load-bearing
Describes a claim that the whole argument's structure depends on, the way a beam holds up a building.
counterclaim
An opposing point the passage raises, usually to answer or dismiss it, not the position the passage actually argues for.
sufficiency
Whether the evidence given is actually enough to support the central claim, a separate question from what the claim is.

Adapted from a column on city transport. 'The city should finish the bike network before it widens another road. Since the first 7 miles of protected lane opened, weekday cycling trips have risen 30 percent and collisions involving a cyclist have fallen. Widening roads is popular, and the mayor has promised it. But a half-built network serves nobody: riders will not use a lane that ends at a highway ramp.' Which sentence carries the passage's central claim?
