Find the part of the sentence that contains an error: The spokesperson refused to comment (1)/ until the investigation would be completed (2)/ to avoid jeopardising (3)/ ongoing proceedings. (4)/
- (a)(1)
- (b)(2)
- (c)(3)
- (d)(4)
Answer
Why
Correct — B. The faulty segment is until the investigation would be completed.
Until opens a time clause, and a time clause does not use will or would to mark future time. The frame here is past ('refused'), so the clause takes a past tense.
It should read 'until the investigation was completed' → option (b).
Why the others are wrong
- (a)(1) — 'The spokesperson refused to comment' is sound. Refuse takes a to-infinitive, and the past tense 'refused' sets the time frame the rest of the sentence must follow.
- (c)(3) — 'To avoid jeopardising' is correct. Avoid is followed by the -ing form, so 'jeopardising' is right, and 'to avoid' is an infinitive of purpose giving the reason for the refusal.
- (d)(4) — 'Ongoing proceedings' is the object of 'jeopardising' and is complete. A plural noun here can take 'the' or go without it, so neither reading makes the segment wrong.
Concept
English does not use will or would to mark future time in a clause of time. After when, until, before, after, as soon as and by the time, a present tense carries the future and a past tense carries the future-in-the-past.
So 'I will wait until he comes', not 'until he will come'. Move the frame into the past and it becomes 'I waited until he came'.
The main clause keeps its will or would. Only the time clause gives it up.
'Until the investigation had been completed' is also correct, stressing that the investigation would finish first. Either repair removes the same fault, the would.
Key facts
- After until, when, before, after and as soon as, a present tense carries future time: 'until the report is ready'.
- In a past frame the same clause takes a past tense: 'refused to comment until the report was ready'.
- Avoid takes the -ing form: 'avoid jeopardising', not 'avoid to jeopardise'.
- Refuse takes a to-infinitive: 'refused to comment'.

Common traps
- Passing over 'would be completed' because 'would' looks natural in a past-tense sentence
- Suspecting 'to avoid jeopardising' because two verb forms sit together, when avoid simply takes the -ing form
One segment carries the fault, and here it is the tense inside a time clause.
