No sooner ______ the executive briefing than journalists began asking pointed questions about the offshore accounts.

Answer and explanation

Correct answer: B. had the minister concluded

  1. Step 1: The correlative structure 'no sooner... than' requires subject-auxiliary inversion in the introductory clause. The past perfect auxiliary 'had' must precede the subject, establishing anteriority to the 'than' clause. Answer: had the minister concluded. Why not the others: "did the minister conclude his formal briefing" uses past simple instead of past perfect, which disrupts standard correlative anteriority; "the minister concluded" fails to invert the auxiliary and subject after initial restrictive negative adverb 'no sooner'; "has the minister spoken" uses present perfect which conflicts with the narrative past tense in the main clause.
