Change the following from active to passive:
By the time the team arrived, the technicians had already repaired the control panel and tested all functions twice.
Show answer & explanation
Correct answer: A
Explanation
Active Voice: '...the technicians (Subject) had already repaired (Verb 1) the control panel (Object 1) and tested (Verb 2) all functions (Object 2) twice.'
Passive Voice: '...the control panel (New Subject 1) had already been repaired, and all functions (New Subject 2) had been tested twice by the technicians (Agent).'
Key Rules Applied:
Past Perfect Tense: In passive voice, 'had + [past participle]' becomes 'had been + [past participle]'.Compound Sentence: Both actions ('repaired' and 'tested') are correctly converted to their passive forms to maintain the original meaning.
Object-Subject Swap: The objects from the active sentence ('control panel' and 'functions') correctly become the subjects of the passive clauses.
Correct Answer: option 1
