Not until the judicial panel ______ all the cross-examined testimonies did the presiding judge deliver the final verdict. Which of the options correctly completes the sentence?
- Ahas reviewed
- had reviewedAnswer
- Creviews
- Dwould review
Answer
The correct option is 'had reviewed' because the past perfect tense is required to indicate an action completed prior to another past action in an inverted past temporal structure.
In complex sentences introduced by negative time adverbials such as 'Not until', an action that occurs and finishes before another past event must be rendered in the past perfect tense ('had reviewed'). The main clause verb ('did... deliver') sets the timeframe in the past, making the past perfect aspect grammatically mandatory for the earlier action.
