Only after the inspection was completed ___ the factory resume production.
答えを見る
正解: A) did
When a limiting adverbial phrase like 'Only after...' is fronted, the main clause is inverted like a question. Since 'resume' is the base form, the auxiliary 'did' is correct (did the factory resume). 'Was' is a be-verb and doesn't combine with 'resume'. 'Has' would need the past participle 'resumed'. 'Could' is grammatically possible, but for stating a fact, 'did' is the natural choice.
