Find the part of the sentence that contains an error: What renders the draft legislation particularly contentious is not its proposed realignment of fiscal powers per se, (1)/ but that it presumes, without empirical substantiation, (2)/ a fiscal equivalence among states whose developmental baselines are (3)/ incommensurable by any normative metric. (4)
- (a)(1)
- (b)(2)
- (c)(3)
- (d)(4)
Answer
Why
Correct — B. The sentence turns on the pair not ... but, and the two things it contrasts must have the same grammatical shape.
After not comes a noun phrase: its proposed realignment of fiscal powers. After but comes a clause: that it presumes, with a subject and verb of its own.
Part (2) breaks the pattern. Keeping the noun-phrase shape repairs it: "but its presumption, without empirical substantiation, of a fiscal equivalence" — option (b).
Why the others are wrong
- (a)(1) — Part (1) is sound on its own: the What-clause subject takes is, and per se means 'in itself'. It sets up the noun-phrase pattern that part (2) then abandons.
- (c)(3) — among suits many states, whose correctly refers back to states, and baselines are agrees in the plural. Nothing here needs repair.
- (d)(4) — incommensurable means having no common standard of measurement, which is exactly the claim being made about the states' baselines. By any normative metric completes it.
Concept
Correlative pairs — not ... but, not only ... but also, either ... or, neither ... nor, both ... and — join two elements of the same grammatical kind: noun phrase with noun phrase, clause with clause.
The test is mechanical. Read the words straight after the first half of the pair, then straight after the second half, and compare their shapes.
Here: not + its proposed realignment (a noun phrase), but + that it presumes (a clause). The shapes differ, so one half has to change.
The mismatch could also be cured from the other side, by recasting part (1) as a clause: "not that it proposes a realignment ... but that it presumes ...". The key places the error in part (2), where the sentence departs from the shape it set up first.
Key facts
- Correlative conjunctions join elements of the same grammatical form.
- Per se means 'in itself' or 'as such'.
- Incommensurable means having no common standard by which two things can be measured.

- Hunting for an agreement or preposition slip in a long sentence and missing a structural fault
- Blaming part (1), where the pattern is set, instead of part (2), where it breaks
The same pairing rule decides 24 Sep 2024, 12:30, English Q.16, where the keyed repair moves not only to sit directly before by giving hints, so each half of not only ... but also is followed by a prepositional phrase.
