By the time the team arrived, the technicians had already repaired the control panel and tested all functions twice.
This question requires changing a sentence from the active voice to the passive voice. The active voice emphasizes the subject performing the action, while the passive voice emphasizes the object receiving the action.
Active Voice: The subject performs the action. Example: The technicians repaired the panel. (Subject: technicians, Verb: repaired, Object: panel)
Passive Voice: The object becomes the subject and receives the action. The original subject (agent) may be introduced with 'by'. Example: The panel was repaired by the technicians. (Subject: panel, Verb: was repaired, Agent: by the technicians)
The original sentence is: "By the time the team arrived, the technicians had already repaired the control panel and tested all functions twice."
To convert the Past Perfect tense to passive voice, we use the structure: Object + had been + Past Participle + (by Subject).
Let's break down the sentence:
Now, we combine the passive parts with the original time clause. The agent ("by the technicians") can be mentioned once if it applies to both actions.
Combining the passive structures:
"By the time the team arrived, the control panel had already been repaired, and all functions had been tested twice by the technicians."
Therefore, Option 1 is the correct passive voice transformation of the original active sentence.
