Find the part of the sentence that contains an error: It was not until the second report (1)/ was leaked to the press (2)/ did the ministry issue (3)/ a formal clarification. (4)
- (a)(1)
- (b)(2)
- (c)(3)
- (d)(4)
Answer
Why
Correct — C. Part (1) opens a cleft sentence: It was not until X. That frame is completed by that, and the clause after that keeps normal order, subject before verb.
Part (3) inverts instead, did the ministry issue, the order English uses when Not until itself opens the sentence.
The repair is "that the ministry issued a formal clarification" → option (c).
Why the others are wrong
- (a)(1) — It was not until is a correct cleft opening, and the key keeps it. The fault lies in part (3), which answers this frame with the wrong word order.
- (b)(2) — was leaked to the press is a correct past simple passive, in step with the past was of the opening frame. Nothing in it needs changing.
- (d)(4) — a formal clarification is the object of issue, a noun phrase with a correct article and adjective. The sentence ends cleanly.
Concept
Two correct shapes exist, and this sentence mixes them.
Fronted negative: Not until the report was leaked did the ministry issue a clarification. The negative opens the sentence, so the auxiliary did comes before the subject.
Cleft: It was not until the report was leaked that the ministry issued a clarification. The negative sits inside It was ... that, so the main clause keeps normal order.
The mix could also be cured from the front, by cutting It was from part (1) to leave Not until ... did.
The key places the error in part (3), which answers the It was frame the sentence has already set up.
Key facts
- Not until X did Y: inversion, because the negative opens the sentence.
- It was not until X that Y: a cleft, with normal word order after that.
- No sooner had X than Y: inversion after a negative opener, completed by than.

Common traps
