Complete the sentence below by filling in the blank with the grammatically correct auxiliary verb form.
Answer:No sooner 【had】 the magistrate pronounced the verdict than a sudden murmur of astonishment rippled through the courtroom.
Answer
The correct auxiliary verb to complete the sentence is 'had'.
When a sentence begins with the negative correlative conjunction 'No sooner', it demands subject-auxiliary inversion in the past perfect tense. The auxiliary 'had' precedes the subject 'the magistrate' and pairs with the past participle 'pronounced', correctly correlating with 'than' followed by the simple past verb 'rippled'.
