Transform the following sentence into active voice.
All the structures built in that area had been demolished due to encroachment.
Show answer & explanation
Correct answer: C
Explanation
Transformation from passive to active voice:
Original Sentence (Passive Voice): "All the structures built in that area had been demolished due to encroachment."
Tense: Past Perfect Passive (Subject + had + been + V3)
In the active voice, we need an acting subject (often "They" or "The authorities" when one isn't specified) and the verb structure changes to:
Subject + had + V3 + object
Maintains the Object Phrase: The phrase "all the structures built in that area" acts as the object.
Conciseness: It avoids adding unnecessary relative clauses (like "that were built") or extra agents (like "by the people") that weren't implied in the original passive construction.
Active voice: They had demolished all the structures built in that area due to encroachment.
