Find the part of the sentence that contains an error: That certain state governments have invoked archaic laws (1)/ to suppress dissent does not only reflect legal opportunism (2)/ but also undermines the constitutional ethos (3)/ that such provisions were meant to uphold. (4)
- (a)(1)
- (b)(2)
- (c)(3)
- (d)(4)
Answer
Why
Correct — B. The trigger is the correlative pair not only … but also, which must join two matching forms.
The second half is a finite verb: but also undermines the constitutional ethos.
So the first half must match it: not only reflects legal opportunism. Part (2) writes does not only reflect, which sets does … reflect against undermines → option (b).
Why the others are wrong
- (a)(1) — Part (1) opens a noun clause correctly. That certain state governments have invoked archaic laws is the start of the sentence's subject, and inside it plural governments takes have invoked.
- (c)(3) — But also undermines is the correct second half. A clause used as a subject is singular, so undermines with -s is right, and it is the form part (2) must match.
- (d)(4) — Were meant to uphold is a correct relative clause: plural provisions takes were, and the past describes what the provisions were originally for.
Concept
Not only … but also is a correlative pair: what follows not only must match, in form, what follows but also.
The subject is a whole clause, That certain state governments have invoked archaic laws to suppress dissent. A clause used as a subject normally takes a singular verb, so both verbs take -s: not only reflects … but also undermines.
Does belongs with not only when the pair is fronted and the clause inverts: Not only does it reflect …, but it also undermines ….
The repair touches part (2) alone: drop does and add -s to reflect. Parts (1), (3) and (4) stay word for word.
Key facts
- Not only … but also joins matching forms: verb with verb, phrase with phrase.
- A clause used as a subject (That … dissent) normally takes a singular verb.
- Fronted not only brings inversion with do: Not only does it reflect …, but it also undermines ….

Common traps
- Marking part (3) because undermines looks odd after does. The -s form is right, and part (2) must change to match it.
- Agreeing the verb with governments or laws instead of with the whole That-clause, which is singular.
